Resumo: Esta encuesta examinó 30 muestras de maní y 15 productos de maní de tres estados (Khartoum, Kordofan y Gadarif) de Sudán para determinar AFB1, AFB2, AFG1, and AFG2 usando cromatografía líquida de alta performance (HPLC) con detección de fluorescencia. La frecuencia de muestras de maní contaminadas con AFB1 de Khartoum, Gadarif y Kordofan fue 58,3%, 57,1%, y 66,7%, respectivamente. Ninguna muestra de maní o producto de maní estaba contaminado con AFG1 o AFG2. El límite de detecciones (LDD) y el límite de cuantificaciones (LDC) estuvieron en un rango de 0,01-0,02 ng g-1 y 0,03-0,05 ng g-1, respectivamente. Algunas muestras de maní contenían concentraciones de AFB1 por encima de los límites regulatorios UE. Las muestras más contaminadas con aflatoxinas fueron las del estado de Kordofan.

Idioma: en.
Resumo: Peanuts (Arachis hipogaea L.) have a great potential for grain production for feed and forage production, being an alternative for producers, as it grows a double product. Grains have excellent quality and contain a greater amount of protein with which to feed the herd. The present study is a cut-off effect study with an application of Stimulate® phytostimulant to determine grain quality and peanut fodder genotype. In the first planting, the peanuts were cultivated under field conditions in a randomized block design in a 4 × 2 × 2 subplot scheme, with four cultivars and two cutting periods, with or without phytostimulant. The cultivars were IAC Tatu ST and Caiana (vertical growth), as well as non-flowering and harvesting seeds. For the second planting, a randomized block design was used with a subplot scheme of 3 × 2 × 2, with three cultivars and 2 cutting periods, with or without phytostimulant. The cultivars were IAC Tatu ST and Caiana (vertical growth) and IAC 503 (prostrate growth). All cultivars contained a high percentage of hay protein in the two plantings. The cultivar IAC 503 was efficient in the production of protein and fiber in the grains in both plantings, demonstrated the potential of protein for animal supplementation, and also presented high grain yield in the summer planting.

A cultura do amendoim (Arachis hipogaea L.) apresenta grande potencial para produção de grão para alimentação e produção de forragem, sendo uma alternativa para os produtores, produzindo a cultura com duplo propósito, grãos de excelente qualidade e significativa quantidade de feno para alimentação do rebanho. O objetivo desta pesquisa foi avaliar o efeito da época de corte com a aplicação do fitoestimulante Stimulate® sobre a qualidade do grão e forragem de genótipo de amendoim. No primeiro plantio o amendoim foi cultivado em condições de campo, em delineamento em blocos ao acaso, em esquema de subsubparcela de 4x2x2, sendo quatro cultivares, dois períodos de corte, com e sem fitoestimulante. As cultivares foramcompostas de IAC Tatu ST e Caiana (crescimento vertical), IAC 886 e IAC 503 (crescimento prostrado) e as épocas de corte foram no florescimento e na colheita. Para o segundo plantio foi utilizado o delineamento em blocos ao acaso, em esquema de subsubparcela de 3x2x2 sendo três cultivares com e sem fitoestimulante e dois períodos de corte. As cultivares foram IAC Tatu ST e Caiana (crescimento vertical) e IAC 503 (crescimento prostrado). Todas as cultivares que receberam corte apresentaram alto percentual de proteína do feno nos dois plantios. A cultivar IAC 503, mostrou-se eficiente na produção de proteína e fibra nos grãos nos dois plantios, demonstraram potencial com fonte de proteína para suplementação animal, além de apresentar alta produtividade de grãos no plantio de verão.

Idioma: en.
Resumo: Among the factors that may influence the germination process of seeds, water deficiency is considered the most important. The present study aims to evaluate the physiological response of peanut genotypes to water deficiency. The experiment was conducted in a completely randomized design with four replications in a 12 x 7 factorial scheme with 12 peanut genotypes and seven polyethylene glycol 6000 concentrations corresponding to osmotic potentials of 0.00; -0.10; -0.20; -0.40; -0.60; -0.80 and -1.00 MPa. The data were submitted to analysis of variance and Tukey's test at a 5% probability level and, when significant, to analysis of variance adjusted to a quadratic polynomial curve. The germination percentage, seed vigor evaluated by the speed germination index, mean germination time, root length and root dry matter of some genotypes were affected by the osmotic potentials. Among the genotypes, there is a differential response related to the water deficiency level. In relation to the physiological response of the seeds, the lineages 506, 599, and 870 and the cultivar IAC Tatu-ST have a higher tolerance of water deficit. The peanut genotypes begin to suffer the effects of water deficiency at the osmotic potential of -0.4 MPa

Entre os fatores externos que podem influenciar o processo germinativo das sementes, a deficiência hídrica é considerada o mais importante. Dessa forma, o objetivo do presente trabalho foi avaliar a resposta fisiológica de sementes de genótipos de amendoim submetidos à deficiência hídrica. O experimento foi conduzido em esquema fatorial 12 x 7, tendo como tratamentos sementes de 12 genótipos de amendoim submetidos a sete concentrações de polietilenoglicol 6000, nos potenciais osmóticos correspondentes a 0,00; -0,10; -0,20; -0,40; -0,60; -0,80; -1,00 MPa. Constatou-se que os genótipos são afetados pelos potenciais osmóticos e, entre os genótipos, há resposta diferenciada em relação ao nível de deficiência hídrica. Em relação à resposta fisiológica das sementes, as linhagens 506, 599, 870 e a cultivar IAC Tatu-ST possuem maiortolerância à deficiência hídrica. Todos os genótipos de amendoim começam a sofrerem os efeitos da deficiência hídrica a partir do potencial osmótico de -0,4 MPa para a maior parte das características avaliadas

Resumo: The objective of work was to study the productive profile of perennial peanut in a rotational stocking environment under different criteria. The treatments corresponded to pre-grazing height of 14 and 18cm or 95% of light interception (LI) distributed in a completely randomized design. The studied variables were forage mass, percentage of structural components, forage mass and the structural components in the lower and upper canopy strata. The entrance criterion of 18cm in height, despite having higher forage mass, presented lower percentage of leaves and higher percentage of stems and forage losses. The criteria of 14cm and 95% light interception presented similar production between them and the highest rate of forage accumulation. In all criteria, in the upper strata of pasture a higher percentage of leaves were found. The criteria of 95% LI and 14cm in height presented the best productive performances. The entry criterion of 18cm presented a higher mass of pre-grazing forage with lower percentage of dead material, but with higher forage losses, resulting from senescent leaves. Due to changes in the structural components, as grazing cycles increase, the interception of 95% of the incident light by the perennial peanut occurs at lower heights.(AU)

O objetivo do presente trabalho foi estudar o perfil produtivo do amendoim forrageiro em um ambiente rotacionado, sob diferentes critérios. Os tratamentos corresponderam à altura de pré-pastejo de 14 e 18cm ou 95% de intercepção de luz (LI), distribuídos em delineamento inteiramente ao acaso. As variáveis estudadas foram massa forrageira, porcentagem de componentes estruturais, densidade da massa forrageira e densidade dos componentes estruturais nos estratos do dossel inferior e superior. O critério de entrada de 18cm de altura, apesar de ter maior massa forrageira, apresentou menor porcentagem de folhas e maior porcentagem de hastes e perdas de forragem. Os critérios de interceptação de luz de 14cm e 95% apresentaram produção similar entre eles e a maior taxa de acumulação de forragem. Em todos os critérios, no estrato superior de pastagem, foi encontrada maior porcentagem de folhas. Os critérios de 95% LI e 14cm de altura apresentaram os melhores desempenhos produtivos. O critério de entrada de 18cm apresentou maior massa de forragem pré-pastagem com menor porcentagem de material morto, mas com maiores perdas de forragem, resultantes de folhas senescentes. Devido às mudanças nos componentes estruturais, à medida que os ciclos de pastagem aumentam, a intercepção de 95% da luz incidente pelo amendoim forrageiro ocorre em alturas mais baixas.(AU)

Resumo: Background: Soil salinity can significantly reduce crop production, but the molecular mechanism of salinity tolerance in peanut is poorly understood. A mutant (S1) with higher salinity resistance than its mutagenic parent HY22 (S3) was obtained. Transcriptome sequencing and digital gene expression (DGE) analysis were performed with leaves of S1 and S3 before and after plants were irrigated with 250 mM NaCl. Results: A total of 107,725 comprehensive transcripts were assembled into 67,738 unigenes using TIGR Gene Indices clustering tools (TGICL). All unigenes were searched against the euKaryotic Ortholog Groups (KOG), gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases, and these unigenes were assigned to 26 functional KOG categories, 56 GO terms, 32 KEGG groups, respectively. In total 112 differentially expressed genes (DEGs) between S1 and S3 after salinity stress were screened, among them, 86 were responsive to salinity stress in S1 and/or S3. These 86 DEGs included genes that encoded the following kinds of proteins that are known to be involved in resistance to salinity stress: late embryogenesis abundant proteins (LEAs), major intrinsic proteins (MIPs) or aquaporins, metallothioneins (MTs), lipid transfer protein (LTP), calcineurin B-like protein-interacting protein kinases (CIPKs), 9-cis-epoxycarotenoid dioxygenase (NCED) and oleosins, etc. Of these 86 DEGs, 18 could not be matched with known proteins. Conclusion: The results from this study will be useful for further research on the mechanism of salinity resistance and will provide a useful gene resource for the variety breeding of salinity resistance in peanut.

Resumo: Background: Because of its strong specificity and high accuracy, real-time quantitative PCR (RT-qPCR) has been a widely used method to study the expression of genes responsive to stress. It is crucial to have a suitable set of reference genes to normalize target gene expression in peanut under different conditions using RT-qPCR. In this study, 11 candidate reference genes were selected and examined under abiotic stresses (drought, salt, heavy metal, and low temperature) and hormone (SA and ABA) conditions as well as across different organ types. Three statistical algorithms (geNorm, NormFinder and BestKeeper) were used to evaluate the expression stabilities of reference genes, and the comprehensive rankings of gene stability were generated. Results: The results indicated that ELF1B and YLS8 were the most stable reference genes under PEG-simulated drought treatment. For high-salt treatment using NaCl, YLS8 and GAPDH were the most stable genes. Under CdCl2 treatment, UBI1 and YLS8 were suitable as stable reference genes. UBI1, ADH3, and ACTIN11 were sufficient for gene expression normalization in low-temperature experiment. All the 11 candidate reference genes showed relatively high stability under hormone treatments. For organs subset, UBI1, GAPDH, and ELF1B showed the maximum stability. UBI1 and ADH3 were the top two genes that could be used reliably in all the stress conditions assessed. Furthermore, the necessity of the reference genes screened was further confirmed by the expression pattern of AnnAhs. Conclusions: The results perfect the selection of stable reference genes for future gene expression studies in peanut and provide a list of reference genes that may be used in the future.

Resumo: A grama missioneira gigante (Axonopus catharinensis Valls) é uma espécie forrageira que merece ser melhor investigada tanto pura como recebendo a inclusão de leguminosas. Objetivou-se avaliar o consumo de MS por ovinos pastejando grama missioneira gigante com ou sem acesso a pastos de amendoim forrageiro (Arachis pintoi cv. Amarillo). Para isso, foi conduzido um experimento prévio com cordeiros alojados em gaiolas metabólicas, gerando-se uma equação para a estimativa do consumo tomando como base a excreção fecal de proteína bruta (PBf), que apresentou R2= 0,91. Em um segundo experimento, foi avaliado o consumo de forragem por ovinos em pastos de grama missioneira gigante com duas alturas de entrada (25 ou 35cm), com ou sem acesso a áreas de amendoim forrageiro por duas horas diárias. A altura de entrada na grama missioneira gigante não alterou o consumo total de MS, mas o acesso aos piquetes da leguminosa aumentou o consumo em aproximadamente 20%. Em conclusão, a grama missioneira gigante pode ser manejada com alturas de entrada entre 25 e 35cm, enquanto o acesso a áreas de amendoim forrageiro por duas horas diárias aumenta o consumo de MO por cordeiros pastejando a missioneira.(AU)

The missioneira gigante grass (Axonopus catharinensis Valls) is a grass that deserves to be better investigated both pure and receiving the inclusion of legumes. The objective of this work was to evaluate the herbage intake by sheep grazing missioneira gigante grass with or without access to peanut grass (Arachis pintoi cv. Amarillo). A previous experiment was conducted using lambs housed in metabolic cages, generating an equation for estimation of herbage intake as a function of faecal crude protein excretion (CPf). The equation presented a value of R 2 = 0.91. In the grazing experiment, the herbage intake was evaluated using missioneira gigante pastures with two pre-grazing sward heights (25 or 35cm), with or without access to peanut areas during two hours per day. The pre-grazing sward height of missioneira gigante did not change the total OM herbage intake, but the access to peanut pastures increased the herbage intake by approximately 20%. In conclusion, missioneira gigante grass has shown flexibility to be used with pre-grazing sward heights between 25 and 35cm, while the access to forage peanut pastures during two hours daily increases herbage OM intake by lambs grazing grass.(AU)

Resumo: Background: Cultivated peanut (Arachis hypogaea L.) is a major oilseed crop worldwide. Fatty acid composition of peanut oil may affect the flavor and shelf life of the resulting food products. Oleic acid and linoleic acid are the major fatty acids of peanut oil. The conversion from oleic acid to linoleic acid is controlled by theΔ12 fatty acid desaturase (FAD) encoded byAhFAD2AandAhFAD2B, two homoeologous genes from A and B subgenomes, respectively. One nucleotide substitution (G:Câ†'A:T) ofAhFAD2Aand an "A" insertion ofAhFAD2Bresulted in high-oleic acid phenotype. Detection ofAhFAD2mutation had been achieved by cleaved amplified polymorphic sequence (CAPS), real-time polymerase chain reaction (qRT-PCR) and allele-specific PCR (AS-PCR). However, a low cost, high throughput and high specific method is still required to detectAhFAD2genotype of large number of seeds. Kompetitive allele specific PCR (KASP) can detect both alleles in a single reaction. The aim of this work is to develop KASP for detectionAhFAD2genotype of large number of breeding materials. Results: Here, we developed a KASP method to detect the genotypes of progenies between high oleic acid peanut and common peanut. Validation was carried out by CAPS analysis. The results from KASP assay and CAPS analysis were consistent. The genotype of 18 out of 179 BC4F2seeds was aabb. Conclusions: Due to high accuracy, time saving, high throughput feature and low cost, KASP is more suitable fordeterminingAhFAD2genotype than other methods.

Resumo: ABSTRACT This study aimed to explore the effects of two siderophore-producing bacterial strains on iron absorption and plant growth of peanut in calcareous soil. Two siderophore-producing bacterial strains, namely, YZ29 and DZ13, isolated from the rhizosphere soil of peanut, were identified as Paenibacillus illinoisensis and Bacillus sp., respectively. In potted experiments, YZ29 and DZ13 enhanced root activity, chlorophyll and active iron content in leaves, total nitrogen, phosphorus and potassium accumulation of plants and increased the quality of peanut kernels and plant biomass over control. In the field trial, the inoculated treatments performed better than the controls, and the pod yields of the three treatments inoculated with YZ29, DZ13, and YZ29 + DZ13 (1:1) increased by 37.05%, 13.80% and 13.57%, respectively, compared with the control. Based on terminal restriction fragment length polymorphism analysis, YZ29 and DZ13 improved the bacterial community richness and species diversity of soil surrounding the peanut roots. Therefore, YZ29 and DZ13 can be used as candidate bacterial strains to relieve chlorosis of peanut and promote peanut growth. The present study is the first to explore the effect of siderophores produced by P. illinoisensis on iron absorption.

Título: Risk assessment of the occurrence of aflatoxin and fungi in peanuts and cashew nuts
Fonte: Braz. J. Pharm. Sci. (Online);55:e18135, 2019. tab, graf, ilus.
Idioma: en.
Resumo: In the present study, the occurrence of fungi and aflatoxins (AFs) in peanut and cashew nut samples was investigated. Mycological analysis revealed the presence of fungi in 58.8% of samples, and assessment of AFs by chromatographic methods revealed that 52.9% were contaminated by AFs. AFB1 was the principal component in all AF-contaminated samples, with a mean level of 14.0, and 1.08 µg/kg in peanut and cashew nut, respectively. Eleven samples (32.4%) exceeded the total AF maximum level (4 µg/kg) and 8 samples (23.5%) exceeded the AFB1 (2 µg/kg) established by the European Commission. Our findings suggest that the incidence of AFs emphasizes the need for regular monitoring and a more stringent food safety system to control AFs at the lowest possible levels in peanuts and cashew nuts. The hypothetical dietary exposure suggests that the food products evaluated may significantly contribute to the overall human exposure
