Tambocerus elongatus (Shen) (Hemiptera: Cicadellidae) is a devastating insect pest species of Camellia sinensis, significantly affecting the yield and quality tea. Due to growing concerns over irrational use insecticides associated food safety, it crucial better understand innate resistance mechanism tea trees T. elongatus. This study aims explore responses different levels infestation. We first focused on primary metabolism found that amino acid decreased with increasing infestation, while sugar accumulation showed an opposite trend. Moreover, secondary metabolite analysis significant increase in flavonoid compounds lignin content after Metabolomics revealed decrease proanthocyanidin level anthocyanidin glycosides (anthocyanins their derivatives) infestation also caused abundance non-ester catechins ester catechins. Furthermore, gene expression transcripts genes involved biosynthesis, such as CsCHI, CsF3H, CsF3'H, CsFNS, CsFLS, CsUFGT, were down-regulated, pathway up-regulated by suggesting probably plays pivotal role plant response Analysis related indicates jasmonate (JA) primarily responds leafhopper damage. These findings suggest JA play preferential production saccharides anthocyanin metabolic are critical during this stress response. Further exploration roles tree could provide theoretical basis for understanding defense against

Photosynthesis is an essential biological process that occurs within chloroplasts. Recently, Frangedakis et al. (2024) reported transcription factors- MpRR-MYB2 and MpRR-MYB5 work along with GLK, also play a role in chloroplast development. The findings from this research could pave the way for engineering crops enhanced photosynthetic efficiency.

Abstract Water transportation to developing tissues relies on the structure and function of plant xylem cells. Plant microtubules govern direction cellulose microfibrils guide secondary cell wall formation morphogenesis. However, relevance microtubule-determined thickening patterns in hydraulic conductivity remains unclear. In present study, we identified a maize (Zea mays) semi-dominant mutant, designated drought-overly-sensitive1 (ZmDos1), upper leaves which wilted even when exposed well-watered conditions during growth; wilting phenotype was aggravated by increased temperatures decreased humidity. Protoxylem vessels stem mutant showed altered (from annular spiral), inner diameters, limited water transport efficiency. The causal mutation for this found be G-to-A gene α-tubulin4, resulting single amino acid substitution at position 196 (E196K). Ectopic expression α-tubulin4 Arabidopsis (Arabidopsis thaliana) changed orientation microtubule arrays, suggesting determinant role assembly thickening. Our findings suggest that spiral thickenings triggered α-tubulin are stretched organ elongation, causing smaller diameter protoxylem affecting maize. This study underscores importance tubulin-mediated regulating hydraulics, improves our understanding relationships between structural features functions, offers candidate genes genetic enhancement

The WRKY gene family is ubiquitously distributed in plants, serving crucial functions stress responses. Nevertheless, the structural organization and evolutionary dynamics of genes cotton have not been fully elucidated. In this study, a total 112, 119, 217, 222 were identified Gossypium arboreum, raimondii, hirsutum, barbadense, respectively. These 670 categorized into seven distinct subgroups unequally across chromosomes. Examination conserved motifs, domains, cis-acting elements, architecture collectively highlighted conservation divergence within cotton. Analysis synteny collinearity further confirmed instances expansion, duplication, loss events among during evolution. Furthermore, GhWRKY31 transgenic Arabidopsis exhibited heightened germination rates longer root lengths under drought salt stress. Silencing led to reduced levels ABA, proline, POD, SOD, along with downregulated expression stress-responsive genes. Yeast one-hybrid molecular docking assays binding capacity W box GhABF1, GhDREB2, GhRD29. findings offer systematic comprehensive insight patterns WRKYs, proposing suitable regulatory framework for developing cultivars enhanced resilience salinity

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. A number exhibited apparent transcript levels detected tissues most disturbed their expression after treatment PEG6000 or natural seedlings. Some showed a similar trend qPCR validation.
