During cytokinesis in plants, trans-Golgi network-derived vesicles accumulate at the center of dividing cells and undergo various structural changes to give rise planar cell plate. However, how this conversion occurs molecular level remains elusive. In study, we report that SH3 Domain-Containing Protein 2 (SH3P2) Arabidopsis thaliana plays a crucial role converting SH3P2 RNAi plants showed cytokinesis-defective phenotypes produced aggregations leading edge localized plate, particularly...
The circadian clock in plants is crucial for regulating stress responses, including cold tolerance. Cold induces the expression of C-REPEAT BINDING FACTOR (CBF) transcription factors, which activate COLD-REGULATED (COR) genes to mitigate cold-induced damage. Previously, we identified that HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENE15 (HOS15)-HISTONE DEACETYLASE 2C (HD2C) complex regulates tolerance by modulating histone deacetylation on COR genes. Our research reports oscillator GIGNATEA...
Abstract Abiotic stress, a serious threat to plants, occurs for extended periods in nature. Abscisic acid (ABA) plays critical role abiotic stress responses plants. Therefore, mediated by ABA have been studied extensively, especially short‐term responses. However, long‐term remain largely unknown. To elucidate the mechanism which plants respond prolonged we used treatment that activates signalling against such as dehydration and investigated mechanisms underlying Long‐term constitutive...
The circadian clock is a timekeeping, homeostatic system that temporally coordinates all major cellular processes. function of the compensated in face variable environmental conditions ranging from normal to stress-inducing conditions. Salinity critical factor affecting plant growth, and plants have evolved SALT OVERLY SENSITIVE (SOS) pathway acquire halotolerance. However, regulatory systems for compensation under salinity are unclear. Here, we show plasma membrane Na
Flowering is the primary stage of plant developmental transition and tightly regulated by environmental factors such as light temperature. However, mechanisms which temperature signals are integrated into photoperiodic flowering pathway still poorly understood. Here, we demonstrate that HOS15, known a GI transcriptional repressor in pathway, controls time response to low ambient At 16°C, hos15 mutant exhibits an early phenotype, HOS15 acts upstream genes (GI, CO, FT). protein abundance...
The demand for trade has led to unsustainable harvesting of medicinal plants, causing a decline in their population natural habitats. This presents notable problem, however, there is lack information regarding the severity threat these resources. To address this, study was conducted identify high-value plants Annapurna Conservation Area Nepal and evaluate potential endangerment by using Rapid Vulnerability Assessment method (RVA). also calculated distribution different habitats size. Results...
Abstract Excess soil salinity significantly impairs plant growth and development. Our previous reports demonstrated that the core circadian clock oscillator GIGANTEA (GI) negatively regulates salt stress tolerance by sequestering SALT OVERLY SENSITIVE (SOS) 2 kinase, an essential component of SOS pathway. Salt induces calcium‐dependent cytoplasmic GI degradation, resulting in activation pathway; however, precise molecular mechanism governing degradation during remains enigmatic. Here, we...
Influenza epidemics frequently and unpredictably break out all over the world, seriously affect breeding industry human activity. Inactivated live attenuated viruses have been used as protective vaccines but exhibit high risks for biosafety. Subunit enjoy biosafety specificity a few weak points compared to inactivated virus or vaccines, especially in low immunogenicity. In this study, we developed new subunit vaccine platform potent, adjuvant-free, multivalent vaccination. The ectodomains of...
The seven members of the 90-kDa heat shock protein (Hsp90) family encode highly conserved molecular chaperones essential for cell survival in Arabidopsis thaliana. Hsp90 are abundant proteins, localized different compartments with AtHsp90.1-4 cytosol and AtHsp90.5-7 organelles. Among AtHsp90, AtHsp90.1, is stress-inducible shares comparatively low sequence identity constitutively expressed AtHsp90.2-4. Even though information available on mammalian cytosolic it unknown whether proteins...
Anthropogenic activities cause the leaching of heavy metals into groundwater and their accumulation in soil. Excess levels toxicity plants, inducing production reactive oxygen species (ROS) possible death caused by resulting oxidative stress. Heavy metal stresses repress auxin biosynthesis transport, inhibiting plant growth. Here, we investigated whether nickel (Ni) is reduced exogenous application Ni stress tolerance Arabidopsis thaliana mediated bifunctional enzyme YUCCA6 (YUC6), which...
Humic acid (HA) is a principal component of humic substances, which make up the complex organic matter that broadly exists in soil environments. HA promotes plant development as well stress tolerance, however precise molecular mechanism for these little known. Here we conducted transcriptome analysis to elucidate mechanisms by enhances salt tolerance. Gene Ontology Enrichment Analysis pointed involvement diverse abiotic stress-related genes encoding HEAT-SHOCK PROTEINs and redox proteins,...
Medicinal plants are the primary source of traditional healthcare systems in many rural areas mostly developing countries. This study aimed to document and analyze diversity, distribution, sustainability medicinal used by Gurung people Sikles region western Nepal. Ethnobotanical data were collected through focus group discussions individual interviews, analyzed using descriptive inferential statistics. Prior informed consent was obtained before each interview. Quantitative ethnobotanical...
Abstract Herbicides play a crucial role in maintaining crop productivity by reducing competition between weeds and crops. Protoporphyrinogen oxidase (PPO)-inhibiting herbicides trigger the photooxidative damage that destroys cell membranes. Tiafenacil is recently developed pyrimidinedione-type PPO-inhibiting herbicide has low IC 50 values plants less toxic humans compared to other PPO inhibitors. Previous reports confirmed mutations Arabidopsis circadian clock-controlled gene GIGANTEA ( GI )...
Light plays a crucial role in plant growth and development, light signaling is integrated with various stress responses to adapt different environmental changes. During this process, excessive protein synthesis overwhelms the protein-folding ability of endoplasmic reticulum (ER), causing ER stress. Although crosstalk between response has been reported plants, molecular mechanisms underlying are poorly understood. Here, we demonstrate that photoreceptor phytochrome B (phyB) induces expression...
