Abstract Priming‐mediated stress tolerance in plants stimulates defense mechanisms and enables to cope with future stresses. Seed priming has been proven effective for against abiotic stresses; however, underlying genetic are still unknown. We aimed assess upland cotton genotypes their transcriptional behaviors under salt successive induced stress. pre‐selected 16 based on previous studies performed morpho‐physiological characterization, from which we selected three genotypes, representing different levels, transcriptomic analysis. subjected these four treatments: (P0), salinity dose at 3‐true‐leaf stage (PD), without (0D), control (CK). Although the displayed distinct expression patterns, identified common differentially expressed genes (DEGs) PD enriched pathways related transferase activity, terpene synthase lipid biosynthesis, regulation of acquired resistance, indicating beneficial role enhancing resistance. Moreover, number unique DEGs associated G. hirsutum purpurascens was significantly higher compared other genotypes. Coexpression network analysis hub involved cell wall biogenesis, glucan metabolic processes, ribosomal RNA binding. Functional characterization XTH6 ( XYLOGLUCAN ENDOTRANSGLUCOSYLASE/HYDROLASE ) using virus‐induced gene silencing revealed that suppressing its improves plant growth Overall, findings provide insights into candidate response effects responses cotton.

Abstract The commonly used precipitation-based drought indices typically rely on probability distribution functions that can be suitable when the data exhibit minimal discrepancies. However, in arid and semi-arid regions, precipitation often display significant discrepancies due to highly irregular rainfall patterns. Consequently, imposing any distributions for analysis such regions may not effective. To address this issue, study employs a novel index called Discrepancy Precipitation Index (DPI), specifically designed regions. Unlike traditional methods, DPI does impose data; instead, it relies discrepancy between mean value. Drought severity classifications (i.e., Drought-I, Drought-II, Drought-III) are proposed based values. is characterize assess meteorological years annual monsoonal over nineteen districts Western Rajasthan, India, during 1901–2019. Additionally, statistic Measure (DM) employed degree of climatology monsoon time series.

Abstract The situation of global warming imparts negative impacts on crop growth and development. Cotton is the most important fiber around globe. However, frequent drought episodes pose serious threats to cotton production worldwide. Due complex genetic structure tolerance, development a tolerant cultivar cumbersome via conventional breeding. Multiple omics techniques have appeared as successful tool for improvement in tolerance. Advanced omics-based biotechniques paved way generation data like transcriptomics, genomics, metabolomics proteomics, which greatly expand knowledge response stress. Omics methodologies provided ways identification quantitative trait loci (QTLs), gene regulatory networks, other pathways against stress cotton.

Unfavorable environmental conditions and climate change impose stress on plants, causing yield losses worldwide. The Indonesian pigmented rice (Oryza sativa L.) cultivars Cempo Ireng Pendek (black rice) Merah Kalimantan Selatan (red are becoming popular functional foods due to their high anthocyanin contents have great potential for widespread cultivation. However, ability grow marginal, high-salinity lands is limited. In this study, we investigated whether seed halopriming enhances salt tolerance in the two cultivars. non-pigmented IR64, a salt-stress-sensitive cultivar, INPARI 35, tolerant, were used as control. We pre-treated seeds with solution before germination then exposed plants of 150 mM NaCl at 21 days after using hydroponic system greenhouse. Halopriming was able mitigate negative effects salinity plant growth, including suppressing reactive oxygen species accumulation, increasing membrane stability index (up two-fold), maintaining photosynthetic pigment contents. had different accumulation proline, varieties: proline content increased IR64 but decreased 35 Selatan. also disparate expression stress-related genes: OsMYB91 positively correlated treatment, whereas OsWRKY42 OsWRKY70 negatively treatment. These findings highlighted benefits salt-affected agro-ecosystems.
