Rice effective panicle is a major trait for grain yield and affected by both the genetic tiller numbers early tillering vigor (ETV) traits to survive environmental adversities. The mechanism behind bud formation has been well described, while genes molecular underlying rice-regulating ETV are unclear. In this study, candidate in regulating have sought quantitative locus (QTL) mapping bulk-segregation analysis resequencing method (BSA-seq) conjoint using rice backcross inbred line (BIL) populations, which were cultivated as late-season of double-cropping systems. By QTL mapping, seven QTLs detected on chromosomes 1, 3, 4, 9, with logarithm odds (LOD) values ranging from 3.52 7.57 explained 3.23% 12.98% observed phenotypic variance.

Rice (Oryza sativa L.) is susceptible to various abiotic stresses, such as salt, cold, and drought. Therefore, there an urgent need explore the relevant genes that enhance tolerance these stresses. In this study, we identified a gene, OsNCED4 (9-cis-epoxycarotenoid dioxygenase 4), which regulates multiple encodes chloroplast-localized abscisic acid (ABA) biosynthetic enzyme. The expression of gene was significantly induced by 150 mM NaCl cold stress. Disruption CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/Cas9-mediated mutagenesis resulted in significant sensitivity salt osnced4 mutant due reduction ABA content excessive accumulation reactive oxygen species (ROS) under Moreover, also drought stress rice seedlings. Taken together, results indicate new regulator for rice, provided potential target enhancing future.

The use of conventional farming methods, excessive reliance on fertilizers and inputs, abrupt shifts in climate have raised significant concerns regarding global agricultural production, particularly developing countries like Nepal. Agriculture products such as rice hold importance Nepal’s agriculture economy, serving a staple food crucial source livelihood for its population. Sustainable cultivation enhancing productivity are imperative ensuring security economic stability the country. Adoption climate-smart (CSA) practices can minimize detrimental effects, promote sustainability, enhance resilience towards change. We surveyed 200 farmers across four municipalities Chitwan District Nepal to explore prevalence socio-economic drivers adoption CSA practices, which include stress-tolerant varieties, efficient water management, diversified cropping, among others. results revealed that pest-resistant plant varieties was common practice study area. Logistic regression increases with an increase education membership climate-related organizations. Similarly, is negatively associated farm size, farmers’ experience, their access credit facilities. Short-term courses training could be initiated complement formal maximize practices. farmer-related organizations should further strengthened capacity facilitate more provide need-based, timely information flow. This highlights potential sustainability change, but also identifies barriers need tailored policy interventions. Our findings contribute understanding dynamics vulnerable settings guide future strategies smallholder communities countries.

Dufulin is a novel immuno-inducer in plants, used to control viral diseases. Salt stress one of the major abiotic stresses affecting plant growth. OsJAZ5 member JAZ (JASMONATE ZIM-DOMAIN) protein family, which are key regulators JA (jasmonic acid) response. In this study, promoted expression gene salt response process rice, and interaction between was confirmed using microscale thermophoresis (MST) molecular docking studies. We further explored function protein, yeast functional complementation studies, physiological biochemical data OsJAZ5-overexpressed transcriptome determine its role enhancing rice tolerance, found that indirectly promotes JA-signaling transduction through interacting proteins OsMYL1 OsMYL2. conclusion, target for achieve enhanced overexpression can improve tolerance stress.
