Plants need to integrate internal and environmental signals mount adequate stress responses. The NUCLEAR PORE COMPLEX (NPC) component HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENES 1 (HOS1) is emerging as such an integrator, affecting responses cold, heat, light, salinity. Stress conditions often converge in a low-energy signal that activates SUCROSE NON-FERMENTING 1-RELATED KINASE (SnRK1) promote tolerance survival. Here, we explored the role of HOS1 SnRK1-dependent response Arabidopsis thaliana, using darkness treatment combination genetic, biochemical, phenotypic assays. We show induction starvation genes plant prolonged are defective hos1 mutant. interacts physically with SnRK1α1 catalytic subunit yeast two-hybrid assays planta, nuclear accumulation reduced Likewise, another NPC mutant, nup160, exhibits lower activation decreased darkness. Importantly, defects background rescued by fusing potent localization or sugar supplementation during dark treatment. Altogether, this work demonstrates importance for SnRK1α1, which key conditions.

Plants alter their morphology and cellular homeostasis to promote resilience under a variety of heat regimes. Molecular processes that underlie these responses have been intensively studied found encompass diverse mechanisms operating across broad range components, timescales temperatures. This review explores recent progress throughout this landscape with particular focus on thermosensing in the model plant Arabidopsis. Direct temperature sensors include photosensors phytochrome B phototropin, clock component ELF3 an RNA switch. In addition, there are heat-regulated mediated by ion channels, lipids lipid-modifying enzymes, taking place at plasma membrane chloroplast. some cases, mechanism perception is well understood but others, remains open question. Potential novel based lipid liquid-liquid phase separation. Finally, future research directions high signalling pathways discussed.

Temperature is a key environmental cue that influences the distribution and behavior of plants globally. Understanding how sense temperature integrate this information into their development important to determine adapt climate change apply knowledge breeding climate-resilient crops. The mechanisms perception in eukaryotes are only just beginning be understood, with multiple molecular phenomena inherent dependencies, such as RNA melting, phytochrome dark reversion, protein phase change, being exploited by nature create thermosensory signaling networks. Here, we review recent progress understanding sensing four major pathways Arabidopsis thaliana occurs: vernalization, cold stress, thermomorphogenesis, heat stress.

RING zinc finger proteins have a conserved domain, mainly function as E3 ubiquitin ligases, and play important roles in plant growth, development, the responses to abiotic stresses such drought, salt, temperature, reactive oxygen species, harmful metals. act stress by modifying degrading stress-related proteins. Here, we review latest progress research on proteins, including their structural characteristics, classification, subcellular localization, physiological functions, with an emphasis tolerance. Under stress, plasma membrane may sensors or abscisic acid (ABA) receptors signaling. Some accumulate nucleus like transcription factors regulate expression of downstream marker genes through direct indirect ways. Most usually cytoplasm ligases response ABA, mitogen-activated protein kinase (MAPK), ethylene signaling pathways. We also highlight areas where further plants is needed.

Abstract Heat stress (HS) adversely affects plant growth and productivity. The Class A1 HS transcription factors (HSFA1s) act as master regulators in the response to HS. However, how HSFA1-mediated transcriptional reprogramming is modulated during remains be elucidated. Here, we report that a module formed by microRNAs miR165 miR166 their target transcript, PHABULOSA (PHB), regulates HSFA1 at translational levels control responses. HS-triggered induction of MIR165/166 Arabidopsis thaliana led decreased expression genes including PHB. overexpression lines mutations miR165/166 enhanced tolerance, whereas knockdown plants expressing miR165/166-resistant form PHB were sensitive directly repressed HSFA1s globally HS-responsive genes. share common gene, HSFA2, which essential for activation responses physically interacted with exerted an antagonistic effect on activity. co-regulated transcriptome upon Together, these findings indicate heat-triggered regulation miR165/166–PHB controls plays critical role Arabidopsis.

Heat stress causes huge losses in the yield of cereal crops. Temperature influences rate plant metabolic and developmental processes that ultimately determine production grains, with high temperatures causing a reduction grain quality. To ensure continued food security, tolerance temperature is rapidly becoming necessary. Brassinosteroids (BR) are class hormones impact to various biotic abiotic stresses regulate growth fertility. Fine-tuning action BR has potential increase cereals' acclimation heat maintain yields. Mechanistically, exogenous applications protect yields through amplifying responses rescuing expression promoters. Varied compounds differential signaling mechanisms across cereals point diversity can be leveraged mitigate stress. Further, hormone transport interaction other molecules plants may critical utilizing as protective agrochemicals against Understanding interplay between responses, lead us comprehensive dogma how tune application for optimizing under challenging environments field.

Double haploid production is the most effective way to create true-breeding lines in a single generation. In Arabidopsis, induction via mutation of centromere-specific histone H3 (cenH3) has been shown when mutant outcrossed wild-type, and wild-type genome remains progeny. However, factors that affect are still poorly understood. Here, we report cenH3 assembly factor Kinetochore Null2 (KNL2) can be used as inducer pollinated by wild-type. We discovered short-term temperature stress knl2 increased efficiency 10-fold. also demonstrated point CENPC-k motif KNL2 sufficient generate haploid-inducing lines, suggesting crops identified naturally occurring or chemically induced population, avoiding generic modification (GM) approach at any stage. Furthermore, cenh3-4 functioned response heat stress, even though it did not induce haploids under standard conditions. Thus, new target gene for generation haploid-inducer showed exposure centromeric protein mutants high strongly increases their efficiency.
