[Ab] Resumo:A bacterial strain, designated TPY-10T, was isolated from calla lily roots in Taiwan and characterized by using a polyphasic taxonomy approach. Cells of strain TPY-10T were Gram-stain-negative, strictly aerobic, motile and creamy white rods. Growth occurred at 15-35 °C (optimum, 25-30 °C), at pH 6-7 (optimum, pH 6) and with 0-1 % NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain TPY-10T belonged to the genus Cellvibrio and was most closely related to Cellvibriomixtus ACM 2601T with sequence similarity of 97.8 %. Strain TPY-10T contained C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C18 : 1ω7c as the predominant fatty acids. The only isoprenoid quinone was Q-9. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The DNA G+C content of the genomic DNA was 49.8 mol%. The DNA-DNA hybridization value for strain TPY-10T with Cellvibriomixtus ACM 2601T was less than 21 %. On the basis of the phylogenetic inference and phenotypic data, strain TPY-10T should be classified as a novel species, for which the name Cellvibrio zantedeschiae sp. nov. is proposed. The type strain is TPY-10T (=BCRC 80525T=LMG 27291T=KCTC 32239T).

[Ab] Resumo:We aimed to identify the main compounds responsible for low temperature-induced yellow pigmentation of the bracts of Zantedeschia aethiopica 'Wedding March'. On the basis of the area ratios estimated from absorbance at 400 nm in HPLC analyses, we identified two flavonoids, isoorientin and swertiajaponin, as such compounds. We also identified two additional flavonoids, isovitexin and swertisin, which do not contribute considerably to the yellow pigmentation. Flavonoids of Zantedeschia bracts seem to belong to the class of flavone C-glycosides.

[Ti] Título:Regreening in spathes of Zantedeschia after anthesis: its physiology and control by fructification and hormones.

[La] Idioma:eng
[Ab] Resumo:The mature pigmented spathe of Zantedeschia is characterized by a developmental process, wherein the spathe regreens after anthesis and prior to senescence of the inflorescence. Previous research has shown that spathe regreening involves redifferentiation of chloroplasts and re-accumulation of chlorophyll, but the detailed physiological changes associated with regreening are still largely unknown. Using Zantedeschia aethiopica and the Zantedeschia pentlandii variety 'Best Gold' as models, this study explores the physiological mechanism and possible roles of fructification, 6-benzylaminopurine (BAP) and gibberellin (GA3 ) in induction or progression of spathe regreening. Application of BAP stimulated regreening in spathe tissue of 'Best Gold' by enhancing accumulation of carotenoid and chlorophyll, and also increasing stacking of grana. In contrast, GA3 retarded formation of double-membrane lamella during chloroplast redifferentiation, thus delaying the onset of regreening. We suggest that these actions of BAP and GA3 have a synergistic effect in delaying the onset of regreening in 'Best Gold' so that when applied together retardation of chlorophyll accumulation, chloroplast redifferentiation and accumulation of carotenoids were enhanced. The elimination of fructification did not prevent the occurrence of regreening in either Zantedeschia model plants, indicating that fructification was not a prerequisite for the induction of regreening. It is still unclear how regreening in Zantedeschia is triggered. We propose that the onset of regreening in Zantedeschia is likely to be a genetically programmed event.

[Ti] Título:Priming of protein expression in the defence response of Zantedeschia aethiopica to Pectobacterium carotovorum.

[Ab] Resumo:The defence response of Zantedeschia aethiopica, a natural rhizomatous host of the soft rot bacterium Pectobacterium carotovorum, was studied following the activation of common induced resistance pathways­systemic acquired resistance and induced systemic resistance. Proteomic tools were used, together with in vitro quantification and in situ localization of selected oxidizing enzymes. In total, 527 proteins were analysed by label-free mass spectrometry (MS) and annotated against the National Center for Biotechnology Information (NCBI) nonredundant (nr) protein database of rice (Oryza sativa). Of these, the fore most differentially expressed group comprised 215 proteins that were primed following application of methyl jasmonate (MJ) and subsequent infection with the pathogen. Sixty-five proteins were down-regulated following MJ treatments. The application of benzothiadiazole (BTH) increased the expression of 23 proteins; however, subsequent infection with the pathogen repressed their expression and did not induce priming. The sorting of primed proteins by Gene Ontology protein function category revealed that the primed proteins included nucleic acid-binding proteins, cofactor-binding proteins, ion-binding proteins, transferases, hydrolases and oxidoreductases. In line with the highlighted involvement of oxidoreductases in the defence response, we determined their activities, priming pattern and localization in planta. Increased activities were confined to the area surrounding the pathogen penetration site, associating these enzymes with the induced systemic resistance afforded by the jasmonic acid signalling pathway. The results presented here demonstrate the concerted priming of protein expression following MJ treatment, making it a prominent part of the defence response of Z. aethiopica to P. carotovorum.

[Ab] Resumo:Zantedeschia aethiopica is an evergreen perennial plant cultivated worldwide and commonly used for ornamental and medicinal purposes including the treatment of bacterial infections. However, the current understanding of molecular and physiological mechanisms in this plant is limited, in comparison to other non-model plants. In order to improve understanding of the biology of this botanical species, RNA-Seq technology was used for transcriptome assembly and characterization. Following Z. aethiopica spathe tissue RNA extraction, high-throughput RNA sequencing was performed with the aim of obtaining both abundant and rare transcript data. Functional profiling based on KEGG Orthology (KO) analysis highlighted contigs that were involved predominantly in genetic information (37%) and metabolism (34%) processes. Predicted proteins involved in the plant circadian system, hormone signal transduction, secondary metabolism and basal immunity are described here. In silico screening of the transcriptome data set for antimicrobial peptide (AMP) -encoding sequences was also carried out and three lipid transfer proteins (LTP) were identified as potential AMPs involved in plant defense. Spathe predicted protein maps were drawn, and suggested that major plant efforts are expended in guaranteeing the maintenance of cell homeostasis, characterized by high investment in carbohydrate, amino acid and energy metabolism as well as in genetic information.

[Ti] Título:A systemic response of geophytes is demonstrated by patterns of protein expression and the accumulation of signal molecules in Zantedeschia aethiopica.

[La] Idioma:eng
[Ab] Resumo:In geophyte plants, such as Zantedeschia, individual leaves are directly connected to a specialized underground storage organ (rhizome/tuber), raising a question regarding systemic resistance as a mechanism of defense. A systemic response requires a transfer of a signal through the storage organ which has been evolutionary adapted to store food, minerals and moisture for seasonal growth and development. We have characterized the nature of induced defense responses in Zantedeschia aethiopica, a rhizomatous (tuber-like) ornamental plant by the application of local elicitation using two well-known defense elicitors, benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH) and methyl jasmonate (MJ). The system consisted leaves in which local responses were directly induced, and systemically responsive leaves in which defense molecules were detected, demonstrating a transported vascular signal. Using anatomical and biochemical tools and local elicitation with MJ, the systemic nature of the response was verified in adjacent leaves by unique protein expression patterns; similarly polyphenol oxidase (PPO) activity was found to increase systemically in all parts of the locally induced plants, including the rhizome, and adjacent leaves; finally, significant accumulation of defense signal molecules such as salicylic and jasmonic acids was recorded in local and systemic leaves following elicitation with BTH. Anatomical sections through the leaves and the rhizome revealed that to be transferred from one leaf to its neighbor, signal molecules must have been transferred through the storage organ. The collected data strongly support our hypothesis that defense signals may and are transferred through the storage organ in monocot geophytes.

[Ab] Resumo:Zantedeschia aethiopica (calla lily) and Anemopsis californica (yerba mansa) are plant species capable of accumulating arsenic (As) and therefore proposed as phytoremediation for removal of As from drinking water. The effects of a continuous 6 month As exposure (34±11 µg/L) from local contaminated groundwater on the antioxidant response of Z. aethiopica and A. californica were evaluated in leaves and stems of the plants bimonthly in a subsurface flow constructed wetland. As increased the activities of the antioxidant enzymes ascorbate peroxidase, glutathione reductase and catalase where higher levels were observed in Z. aethiopica than A. californica. No significant differences were detected on lipid peroxidation levels or antioxidant capacity evaluated by ORAC and DPPH assays or total phenol contents in any part of the plant, although in general the leaves of both plants showed the best antioxidant defense against the metal. In conclusion, Z. aethiopica and A. californica were able to cope to As through induction of a more sensitive enzymatic antioxidant response mechanism.

[Ab] Resumo:PREMISE OF THE STUDY: A new set of microsatellite or simple sequence repeat (SSR) markers from expressed sequence tags (ESTs) was developed for arum lily (Zantedeschia aethiopica), which is one of the most iconic and widely recognized ornamental plants in the world. • METHODS AND RESULTS: Using 2175 unigenes derived from 4283 random ESTs in arum lily, 166 primer pairs were designed and tested for amplification in 24 accessions from Asia, Europe, and Africa. A total of 43 loci were polymorphic, with the number of alleles per locus ranging from two to 10. The observed heterozygosity, expected heterozygosity, and polymorphism information content ranged from 0.2313 to 0.8480, 0.3034 to 0.8648, and 0.1015 to 0.7364, respectively. • CONCLUSIONS: These novel polymorphic EST-SSR markers will facilitate future studies of genetic variation and molecular-assisted breeding systems in arum lily.

[Ti] Título:Sinks for photosynthetic electron flow in green petioles and pedicels of Zantedeschia aethiopica: evidence for innately high photorespiration and cyclic electron flow rates.

[Ab] Resumo:A combination of gas exchange and various chlorophyll fluorescence measurements under varying O(2) and CO(2) partial pressures were used to characterize photosynthesis in green, stomata-bearing petioles of Zantedeschia aethiopica (calla lily) while corresponding leaves served as controls. Compared to leaves, petioles displayed considerably lower CO(2) assimilation rates, limited by both stomatal and mesophyll components. Further analysis of mesophyll limitations indicated lower carboxylating efficiencies and insufficient RuBP regeneration but almost similar rates of linear electron transport. Accordingly, higher oxygenation/carboxylation ratios were assumed for petioles and confirmed by experiments under non-photorespiratory conditions. Higher photorespiration rates in petioles were accompanied by higher cyclic electron flow around PSI, the latter being possibly linked to limitations in electron transport from intermediate electron carriers to end acceptors and low contents of PSI. Based on chlorophyll fluorescence methods, similar conclusions can be drawn for green pedicels, although gas exchange in these organs could not be applied due to their bulky size. Since our test plants were not subjected to stress we argue that higher photorespiration and cyclic electron flow rates are innate attributes of photosynthesis in stalks of calla lily. Active nitrogen metabolism may be inferred, while increased cyclic electron flow may provide the additional ATP required for the enhanced photorespiratory activity in petiole and pedicel chloroplasts and/or the decarboxylation of malate ascending from roots.

[Ab] Resumo:Recombinant Zantedeschia aethiopica agglutinin (ZAA) was expressed in Escherichia coli as N-terminal His-tagged fusion. After induction with isopropylthio-beta-D-galactoside (IPTG), the recombinant ZAA was purified by metal-affinity chromatography. The purified ZAA protein was applied in anti-fungal assay and the result showed that recombinant ZAA had anti-fungal activity towards leaf mold (Fulvia fulva), one of the most serious phytopathogenic fungi causing significant yield loss of crops. This study suggests that ZAA could be an effective candidate in genetic engineering of plants for the control of leaf mold.
