Abstract Tartary buckwheat ( Fagopyrum tataricum ) is an important crop used for edible food and medicinal usage. Drought annually brings reduction in yield quality, causing enormous economic losses. Transcription factors are often involved the regulation of plant responses to environmental stresses. In this study, we identified 233 MYB transcription tartary classified them into 13 groups, including 1R, R2R3, 3R, 4R types. Gene structure conserved motifs these FtMYBs suggested relative conservation within each group. There strong collinearity genomes F. , with identifying syntenic gene pairs FtMYB . Further, expansion genes was attributed whole genome duplication. The enrichment analysis cis -acting elements indicated that may participate abiotic stress responses. transcriptional changes were then investigated using public data qPCR.

FtPinG0005108900.01 shown activated by drought treatment, its encoded protein localizes nucleus, revealing it as typical factor. Overexpression increase tolerance, transcriptome lignin synthesis other than flavonoid biosynthesis pathway overexpressing plants following treatment. Our results provided detailed evolution comparative genomic information dissected function response drought.

Calcium (Ca2+), a second messenger, plays crucial role in plant growth and development as well responding to biotic abiotic stresses. In this work, we explored the of exogenous calcium alleviating cold stress examined relationship between chloride (CaCl2) channel blockers, lanthanum (LaCl3), tea plants under at physiological transcriptional levels. Exogenous Ca2+ partially offsets negative impacts which increased tolerance by significantly raising photochemical efficiency PSII, protective enzyme activities, ABA content, reduced relative electrical conductivity (REC) level malondialdehyde (MDA) concentration. At transcriptome level, enhanced expression key genes involved response pathways. Nevertheless, LaCl3 treatment not only inhibited activities antioxidant enzymes including superoxide dismutase (SOD), peroxidase (POD) catalase (CAT), but also damage. This study aims provide essential insight into stress, better understand molecular mechanisms that facilitate Ca-mediated tolerance.

Rice (Oryza sativa) produces phenolamides and diterpenoids as major phytoalexins. Although the biosynthetic pathways of in plants have been revealed, knowledge their accumulation regulatory mechanisms remains limited, and, particular, no co-regulatory factor has identified to date. Here, using a combined co-expression evolutionary analysis, we basic helix–loop–helix (bHLH) transcription OsbHLH5 positive bifunctional regulator phenolamide diterpenoid biosynthesis rice. Metabolomic analysis revealed that significantly increased content (such feruloyl tryptamine (Fer-Trm) p-coumaroyl tyramine (Cou-Tyr)) phytoalexins momilactones A, B) overexpression lines, while was reduced knockout lines. Gene expression dual-luciferase assays activates genes (including putrescine hydroxycinnamoyltransferase 3 (OsPHT3), hydroxycinnamoyltransferases 1/2 (OsTHT1/2), benzoyltransferase 2 (OsTBT2)) well copalyl diphosphate synthase 4 (OsCPS4) kaurene synthase-like 4/7/10/11 (OsKSL4/7/10/11)). Furthermore, demonstrated is induced by jasmonic acid (JA), pathogen inoculation indicated transgenic rice leads enhanced resistance Xanthomonas oryzae pv. (Xoo). Overall, biotic stress induces phytoalexin partly an OsbHLH5-dependent manner, providing new insights into metabolic interactions involved response offering valuable gene resources for development, through genetic improvement, varieties are resistant diseases.
