Soil salinity caused by NaCl is a major challenge to agricultural crops worldwide. For this, two WRKY transcription factors were evaluated for their role in salt stress tolerance tomato plants (Solanum lycopersicum; Sl). SlWRKY36 and SlWRKY51 provided novel insight into the regulatory mechanism against via virus-induced gene silencing (VIGS). Salt significantly reduced chlorophyll-a, an abundant form of chlorophyll content 6.0 5.1 mg/g proline 0.06 0.09 respectively silenced plants. This shows that affected act as osmo-protectant damaged photosynthetic pigments Similarly, concentrations Na+/ K+ ratio also showed higher trend 14 days after with 5.5 8.9 concentration at 200 mM showing promotes Na+/K+ ion under stress. Also, responsive genes such overly sensitive SOS1 Na+/H+ exchanger NHX1 displayed lower transcript level negative regulation silencing. Collectively, these findings suggest first time positive regulators managing homeostasis, machinery transcriptional reprogramming. Overall, explored potential candidates engineering crop

Abstract Plant pigments are the natural source of color perceived by human senses. They have captivated researchers to explore their structural, physical, and chemical properties, synthesis mode, physiological significance. secondary metabolites in plants metabolism, growth regulation, photosynthesis, defense. Chlorophylls, carotenoids, anthocyanins, betalains major classes colors contributing shades textiles, foods, cosmetics. The bioactive properties these compounds used apply as pharmaceuticals treat chronic degenerative diseases like hypertension, diabetes, cancer, cardiovascular disorders. This review discusses classification, biosynthesis, metabolic activities, commercial applications plant pigments, knowledge gaps pigment identification application prospects. developments technologies such non‐encapsulation preserve unstable extracts for use transporter genes involved synthesizing essential pigments. However, additional research is required gain insight into candidate gene orchestrating stress responses potential engineering tolerance various crops.

As an important genus in Orchidaceae, Cymbidium has rich ecological diversity and significant economic value. DNA binding with one zinc finger (Dof) proteins are pivotal plant-specific transcription factors that play crucial roles the growth, development, stress response of plants. Although Dof genes have been identified functionally analyzed numerous plants, exploration Orchidaceae remains limited. We conducted a thorough analysis gene family goeringii, C. ensifolium, sinensis. In total, 91 (27 CgDofs, 34 CeDofs, 30 CsDofs) were identified, divided into five groups (I–V) based on phylogenetic analysis. All motif 1 2 conserved domains over half contained introns. Chromosomal localization collinearity revealed their evolutionary relationships potential duplication events. Analysis cis-elements CsDofs promoters showed light-responsive most common, followed by hormone-responsive elements, plant growth-related abiotic elements. three species primarily exhibit random coil structure, while homology modeling exhibited similarity. addition, RT-qPCR expression levels nine CgDofs changed greatly under heat stress. CgDof03, CgDof22, CgDof27, CgDof08, CgDof23 varying degrees upregulation. Most upregulated belong to group I, indicating I great for high-temperature resistance. conclusion, our study systematically demonstrated molecular characteristics different species, preliminarily patterns stress, provided reference further breeding orchids.

Context Heat shock proteins play a vital role in cellular homeostasis by protecting against various environmental stresses, which facilitates the survival of plants under unfavourable conditions. Aims We aimed to provide first comprehensive genomic and expression analysis HSP70 gene family betel palm (Areca catechu) elucidate its heat stress response. Methods Genomic revealed 34 putative genes distributed across 13 chromosomes. These were renamed AcatHSP70 classified into five subfamilies (A–E) based on phylogenetic analysis. are mostly localised chloroplast, cytoplasm, nucleus. Gene ontology that these involved stress. The duplication events only segmental duplications. subjected seedlings (2 years old) controlled conditions for 30 days at high, low, room temperatures analyses genes. Key results Expression eight candidate (AcatHSP70-3, AcatHSP70-13, AcatHSP70-22, AcatHSP70-19, AcatHSP70-21, AcatHSP70-24, AcatHSP70-25, AcatHSP70-26) showed significantly higher high-temperature AcatHSP70-5 low-temperature treatment, AcatHSP70-16 was responsive temperature treatment. Conclusion conclude majority crucial thermal conditions, respond as shown quantitative reverse transcription polymerase chain reaction Implications This characterisation provides novel insights protection mechanisms palms changing climates.
