[Ab] Resumo:Phytophthora austrocedri is causing widespread mortality of Austrocedrus chilensis in Argentina and Juniperus communis in Britain. The pathogen has also been isolated from J. horizontalis in Germany. Isolates from Britain, Argentina, and Germany are homothallic, with no clear differences in the dimensions of sporangia, oogonia, or oospores. Argentinian and German isolates grew faster than British isolates across a range of media and had a higher temperature tolerance, although most isolates, regardless of origin, grew best at 15°C and all isolates were killed at 25°C. Argentinian and British isolates caused lesions when inoculated onto both A. chilensis and J. communis; however, the Argentinian isolate caused longer lesions on A. chilensis than on J. communis and vice versa for the British isolate. Genetic analyses of nuclear and mitochondrial loci showed that all British isolates are identical. Argentinian isolates and the German isolate are also identical but differ from the British isolates. Single-nucleotide polymorphisms are shared between the British and Argentinian isolates. We concluded that British isolates and Argentinian isolates conform to two distinct clonal lineages of P. austrocedri founded from the same as-yet-unidentified source population. These lineages should be recognized and treated as separate risks by international plant health legislation.

[Ab] Resumo:Accurate tree height and diameter at breast height (dbh) are important input variables for growth and yield models. A total of 5503 Chinese Metasequoia trees were used in this study. We studied 53 fitted models, of which 7 were linear models and 46 were non-linear models. These models were divided into two groups of single models and multivariate models according to the number of independent variables. The results show that the allometry equation of tree height which has diameter at breast height as independent variable can better reflect the change of tree height; in addition the prediction accuracy of the multivariate composite models is higher than that of the single variable models. Although tree age is not the most important variable in the study of the relationship between tree height and dbh, the consideration of tree age when choosing models and parameters in model selection can make the prediction of tree height more accurate. The amount of data is also an important parameter what can improve the reliability of models. Other variables such as tree height, main dbh and altitude, etc can also affect models. In this study, the method of developing the recommended models for predicting the tree height of native Metasequoias aged 50-485 years is statistically reliable and can be used for reference in predicting the growth and production of mature native Metasequoia.

[Ab] Resumo:The impact of phenological stages (vegetative, flowering and fruiting stages) on chemical composition, antioxidant, and antimicrobial activities of Tetraclinis articulata (Vahl) Mast. parts essential oils were investigated for the first time. GC and GC/MS analyses pointed to a quantitative variability of components; terpene hydrocarbons derivatives, represented by α-pinene (16.38 ± 0.19 - 31.78 ± 0.35%) and limonene (3.41 ± 0.07 - 9.49 ± 0.14%) as major components, predominate at the vegetative stage, whereas oxygenated derivatives, represented by camphor (16.11 ± 0.23 - 26.17 ± 0.29%) and bornyl acetate (15.21 ± 0.21 - 27.33 ± 0.33%) as major components, predominate at the fruiting stage. Furthermore, our findings showed that the plant parts collected at the fruiting stage possess the highest antioxidant activity and the best antimicrobial activity against the tested microorganisms, than plant parts collected at the vegetative and flowering stages. This highlighted variability reflects the high impact of phenological cycle on chemical composition and biological activities, which led to conclude that we should select essential oils to be investigated carefully depending on phenological stage, in order to have the highest effectiveness of essential oil in terms of biological activities for human health purposes.

[Ab] Resumo:In the present work, the hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD) kinetics of essential oil (EO) extracted from Tetraclinis articulata (Vahl) Mast. wood was conducted, in order to assess the impact of extraction time and technique on chemical composition and biological activities. Gas chromatography (GC) and GC/mass spectrometry analyses showed significant differences between the extracted EOs, where each family class or component presents a specific kinetic according to extraction time, technique and especially for the major components: camphene, linalool, cedrol, carvacrol and α-acorenol. Furthermore, our findings showed a high variability for both antioxidant and anti-inflammatory activities, where each activity has a specific effect according to extraction time and technique. The highlighted variability reflects the high impact of extraction time and technique on chemical composition and biological activities, which led to conclude that we should select EOs to be investigated carefully depending on extraction time and technique, in order to isolate the bioactive components or to have the best quality of EO in terms of biological activities and preventive effects in food.

[Ab] Resumo:Glyptostrobus pensilis, belonging to the monotypic genus Glyptostrobus (Family: Cupressaceae), is an ancient conifer that is naturally distributed in low-lying wet areas. Here, we report the complete chloroplast (cp) genome sequence (132,239 bp) of G. pensilis. The G. pensilis cp genome is similar in gene content, organization and genome structure to the sequenced cp genomes from other cupressophytes, especially with respect to the loss of the inverted repeat region A (IRA). Through phylogenetic analysis, we demonstrated that the genus Glyptostrobus is closely related to the genus Cryptomeria, supporting previous findings based on physiological characteristics. Since IRs play an important role in stabilize cp genome and conifer cp genomes lost different IR regions after splitting in two clades (cupressophytes and Pinaceae), we performed cp genome rearrangement analysis and found more extensive cp genome rearrangements among the species of cupressophytes relative to Pinaceae. Additional repeat analysis indicated that cupressophytes cp genomes contained less potential functional repeats, especially in Cupressaceae, compared with Pinaceae. These results suggested that dynamics of cp genome rearrangement in conifers differed since the two clades, Pinaceae and cupressophytes, lost IR copies independently and developed different repeats to complement the residual IRs. In addition, we identified 170 perfect simple sequence repeats that will be useful in future research focusing on the evolution of genetic diversity and conservation of genetic variation for this endangered species in the wild.

[Ab] Resumo:Although numerous hypotheses have been proposed to prevent chemotherapy-induced alopecia (CIA), effective pharmaceuticals have yet to be developed. In our study, the back hairs of C57BL/6 mice were factitiously removed. These mice were then treated with cedrol or minoxidil daily. Mice with early-stage anagen VI hair follicles were treated with cyclophosphamide (CYP, 125mg/kg) to induce alopecia. The CYP-damaged hair follicles were observed and quantified by using a digital photomicrograph. The results demonstrated that the minoxidil-treated mice suffered from complete alopecia similar to the model 6days after CYP administration. Simultaneously, the cedrol-treated (200mg/kg) mice manifested mild alopecia with 40% suppression. Histological observation revealed that anagen hair follicles of the cedrol-pretreated mice (82.5%) likely provided from damage compared with the sparse and dystrophic hair follicles of the model mice (37.0%). Therefore, the use of topical cedrol can prevent hair follicle dystrophy and provide local protection against CIA.

[Ab] Resumo:Platycladus orientalis (L.) Franco is traditionally known to potentiate hair growth promotion. However, there has been no report on its main active ingredient responsible for the hair growth activity. In the current work, cedrol as a major constituent from P. orientalis was evaluated for its potential on hair growth in vivo. Different concentrations of cedrol (10, 20 and 30mg/mL) were applied topically over the shaved skin of C57BL/6 mice and monitored for 21days. Results indicated that cedrol significantly promoted hair growth in a dose-dependent manner, particularly for the female mice. Both male and female mice groups treated with 30mg/mL cedrol required shorter time than the blank control and 2% minoxidil groups at different growth stages. Compared with the blank control (8.87mm) and 2% minoxidil (9.94mm) groups at 21days, the hair length of female mice treated with 30mg/mL cedrol showed a remarkable increase with the value of 11.07mm. Hair in male and female mice groups treated with 30mg/mL cedrol was heavier than the 2% minoxidil (38.2 and 35.9mg, respectively) groups with the weight of 42.6 and 45.2mg, respectively. Further observation of the hair follicle demonstrated that cedrol exerted a remarkable effect on the hair follicle length. These findings suggested that cedrol may be the main active ingredient of P. orientalis and have the potential of becoming a new hair growth promoter.

[Ab] Resumo:Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is an important coniferous tree species for timber production, which accounts for ~40% of log supply from plantations in southern China. Chloroplast genetic engineering is an exciting field to engineer several valuable tree traits. In this study, we revisited the published complete Chinese fir (NC_021437) and four other coniferous species chloroplast genome sequence in Taxodiaceae. Comparison of their chloroplast genomes revealed three unique inversions found in the downstream of the gene clusters and evolutionary divergence were found, although overall the chloroplast genomic structure of the Cupressaceae linage was conserved. We also investigated the phylogenetic position of Chinese fir among conifers by examining gene functions, selection forces, substitution rates, and the full chloroplast genome sequence. Consistent with previous molecular systematics analysis, the results provided a well-supported phylogeny framework for the Cupressaceae that strongly confirms the "basal" position of Cunninghamia lanceolata. The structure of the Cunninghamia lanceolata chloroplast genome showed a partial lack of one IR copy, rearrangements clearly occurred and slight evolutionary divergence appeared among the cp genome of C. lanceolata, Taiwania cryptomerioides, Taiwania flousiana, Calocedrus formosana and Cryptomeria japonica. The information from sequence divergence and length variation of genes could be further considered for bioengineering research.

[Ab] Resumo:This research reports first time antiviral activity of sugiol, a diterpenoid isolated from Metasequoia glyptostroboides in terms of its ability to inhibit in vitro growth of H1N1 influenza virus. Antiviral potential of sugiol was evaluated through hcytopathogenic reduction assay using Madin-Darby canine kidney (MDCK) cell line. Sugiol (500 µg/ml) was found to exhibit considerable anti-cytopathic effect on MDCK cell line confirming its antiviral efficacy against H1N1 influenza virus. These findings strongly reinforce the suggestion that sugiol could be a candidate of choice in combinational regimen with potential antiviral efficacy.

[Ab] Resumo:In order to get better knowledge about the volatiles produced by Xanthocyparis vietnamensis, a species recently discovered in Vietnam, its wood oil has been analyzed by a combination of chromatographic (GC, CC) and spectroscopic (GC-MS, (13)C-NMR) techniques. Forty components that accounted for 87.9% of the oil composition have been identified. The composition is dominated by nootkatene (20.7%), 11,12,13-tri-nor-eremophil-1(10)-en-7-one (17.2%), γ-eudesmol (5.1%), nootkatone (4.7%), valencene (3.5%) and 13-nor-eremophil-1(10)-en-11-one (2.6%). The structure of two new compounds-10-epi-nor-γ-eudesmen-11-one and 12-hydroxy-isodihydroagarofuran-has been elucidated, while 11,12,13-tri-nor-eremophil-1(10)-en-7-ol is reported as a natural product for the first time. The composition of X. vietnamensis wood oil varied drastically from those of leaf oils, dominated by hedycaryol (34.4%), phyllocladene (37.8%) or by pimara-6(14)-15-diene (19.4%).
