Purple foliage always appears in Camellia sinensis families; however, the transcriptional regulation of anthocyanin biosynthesis is unknown. The tea bud sport cultivar 'Zijuan' confers an abnormal pattern accumulation, resulting a mutant phenotype that has striking purple color young and stem. In this study, we aimed to unravel underlying molecular mechanism biosynthetic C. sinensis. Our results revealed activation R2R3-MYB transcription factor (TF) anthocyanin1 (CsAN1) specifically...
Plants produce countless specialized metabolites crucial for their development and fitness, many are useful bioactive compounds. Capsaicinoids intriguing genus-specialized that confer a pungent flavor to Capsicum fruits, they widely applied in different areas. Among the five domesticated species, chinense has high content of capsaicinoids, which results an extremely hot flavor. However, species-specific upregulation capsaicinoid-biosynthetic genes (CBGs) evolution peppers not well...
Plant biosynthesis involves numerous specialized metabolites with diverse chemical natures and biological activities. The of often exclusively occurs in response to tissue-specific combinatorial developmental cues that are controlled at the transcriptional level. Capsaicinoids a group confer pungent flavor pepper fruits. Capsaicinoid fruit placenta combines its cues. Although capsaicinoid biosynthetic pathway has been largely characterized, regulatory mechanisms control metabolism have not...
Abstract The organization of chromatin into self-interacting domains is universal among eukaryotic genomes, though how and why they form varies considerably. Here we report a chromosome-scale reference genome assembly pepper ( Capsicum annuum ) explore its 3D through integrating high-resolution Hi-C maps with epigenomic, transcriptomic, genetic variation data. Chromatin folding in are as prominent TADs mammals but exhibit unique characteristics. They tend to coincide heterochromatic regions...
Carotenoids are major accessory pigments in the chloroplast, and they also act as phytohormones volatile compound precursors to influence plant development confer characteristic colours, affecting both aesthetic nutritional value of fruits. Carotenoid pigmentation ripening fruits is highly dependent on developmental trajectories. Transcription factors incorporate phytohormone signalling regulate biosynthesis process. By contrast well-established pathways regulating ripening-related...
Chili pepper (Capsicum) is known for its unique fruit pungency due to the presence of capsaicinoids. The evolutionary history capsaicinoid biosynthesis and mechanism their tissue specificity remain obscure lack high-quality Capsicum genomes. Here, we report two telomere-to-telomere (T2T) gap-free genomes C. annuum wild nonpungent relative rhomboideum investigate evolution in chili peppers. We precisely delineate centromeres, which high-copy tandem repeats but are extensively invaded by CRM...
Jasmonates (JAs) play an important role in plant developmental processes and regulate the biosynthesis of various specialized metabolites, transcription factors are crucial mediating JA signaling to these processes. Capsaicinoids (Caps) intriguing metabolites produced uniquely by Capsicum species that give their fruits a pungent flavor defend against herbivory pathogens. In this study, we identify R2R3-MYB factor CaMYB108 demonstrate its roles regulating Caps stamen development....
Abstract Background The basic helix–loop–helix (bHLH) transcription factors (TFs) serve crucial roles in regulating plant growth and development typically participate biological processes by interacting with other TFs. Capsorubin capsaicinoids are found only Capsicum , which has high nutritional economic value. However, whether bHLH family genes regulate capsorubin capsaicinoid biosynthesis these TFs remains unknown. Results In this study, a total of 107 CabHLHs were identified from the...
Plants are constantly challenged by environmental stresses, including drought and high salinity. Improvement of osmotic stress tolerance without yield decrease has been a great challenge in crop improvement. The Arabidopsis ENHANCED DROUGHT TOLERANCE1/HOMEODOMAIN GLABROUS11 (AtEDT1/HDG11), protein the class IV HD-Zip family, demonstrated to significantly improve Arabidopsis, rice, pepper. Here, we report that AtEDT1/HDG11 confers Chinese kale. AtEDT1/HDG11-overexpression lines exhibit...
Abstract Background ERF transcription factors (TFs) belong to the Apetala2/Ethylene responsive Factor (AP2/ERF) TF family and play a vital role in plant growth development processes. Capsorubin capsaicinoids have relatively high economic nutritional value, they are specifically found Capsicum . However, there is little understanding of how ERFs participate regulatory networks capsorubin biosynthesis. Results In this study, total 142 were identified annuum genome. Subsequent phylogenetic...
Abstract The yield of pepper plants ( Capsicum spp.) is their most important trait and affected by the flower number flowering time. annuum produces a single per node has an early habit. By contrast, chinense yields multiple flowers late character. However, genetic mechanism underlying control these floral traits remains largely unknown. In this study, 150 F 2 populations from interspecific cross between inbred lines 740 C . ) CA1 parents were used to construct molecular linkage map using...
DNA methylation plays important roles in regulating gene expression during development. However, little is known about the influence of on secondary metabolism leaf development tea plant (Camellia sinensis). In this study, we combined methylome, transcriptome, and metabolome to investigate dynamic changes its potential regulatory metabolite biosynthesis. level genomic increased as progressed from tender old leaf. It additionally exhibited a similar distribution across background at two...
The fruit development and ripening process involve a series of changes regulated by fine-tune gene expression at the transcriptional level. Acetylation levels histones on lysine residues are dynamically histone acetyltransferases (HATs) deacetylases (HDACs), which play an essential role in control expression. However, their regulating process, especially pepper (Capsicum annuum), typical non-climacteric fruit, remains to understand. Herein, we performed genome-wide analyses HDAC HAT family...
Bacterial wilt caused by Ralstonia solanacearum is a severe soil-borne disease globally, limiting the production in Solanaceae plants. SmNAC negatively regulated eggplant resistance to (BW) though restraining salicylic acid (SA) biosynthesis. However, other mechanisms through which regulates BW remain unknown. Here, we identified an interaction factor, SmDDA1b, encoding substrate receptor for E3 ubiquitin ligase, from cDNA library using as bait. SmDDA1b expression was promoted R. inoculation...
