Abstract Global mean temperature is increasing at a rapid pace due to the emission of greenhouse gases majorly from anthropogenic practices and predicted rise up 1.5°C above pre‐industrial level by year 2050. The warming climate affecting global crop production altering biochemical, physiological, metabolic processes resulting in poor growth, development, reduced yield. Maize susceptible heat stress, particularly reproductive early grain filling stages. Interestingly, stress impact on crops closely regulated associated environmental covariables such as humidity, vapor pressure deficit, soil moisture content, solar radiation. Therefore, tolerance considered complex trait, which requires multiple levels regulations plants. Exploring genetic diversity landraces wild accessions maize promising approach identify novel donors, traits, quantitative trait loci (QTLs), genes, can be introgressed into elite cultivars. Indeed, genome wide association studies (GWAS) for mining potential QTL(s) dominant gene(s) major route improvement. Conversely, mutation breeding being utilized generating variation existing populations with narrow background. Besides approaches, augmented shock factors (HSFs) proteins (HSPs) have been reported transgenic provide tolerance. Recent advancements molecular techniques including clustered regularly interspaced short palindromic repeats (CRISPR) would expedite process developing thermotolerant genotypes.

Abiotic stresses increasingly threaten existing ecological and agricultural systems across the globe. Plant roots perceive these in soil adapt their architecture accordingly. This review provides insights into recent discoveries showing importance of root system (RSA) plasticity for survival development plants under heat, cold, drought, salt, flooding stress. In addition, we molecular regulation hormonal pathways involved controlling RSA plasticity, main growth, branching lateral hair development, formation adventitious roots. Several affect anatomy by causing aerenchyma formation, lignin suberin deposition, Casparian strip modulation. Roots can also actively grow toward favorable conditions avoid environments detrimental to development. Recent advances understanding cellular mechanisms behind different tropisms are discussed. Understanding will be instrumental crops that resilient face abiotic

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.

How the plasma membrane senses external heat-stress signals to communicate with chloroplasts orchestrate thermotolerance remains elusive. We identified a quantitative trait locus, Thermo-tolerance 3 (TT3), consisting of two genes, TT3.1 and TT3.2, that interact together enhance rice reduce grain-yield losses caused by heat stress. Upon stress, membrane-localized E3 ligase translocates endosomes, on which ubiquitinates chloroplast precursor protein TT3.2 for vacuolar degradation, implying might serve as potential thermosensor. Lesser accumulated, mature proteins in are essential protecting thylakoids from Our findings not only reveal TT3.1-TT3.2 genetic module at one locus transduces but also provide strategy breeding highly thermotolerant crops.

We present unresolved questions in plant abiotic stress biology as posed by 15 research groups with expertise spanning eco-physiology to cell and molecular biology. Common themes of these include the need better understand how plants detect water availability, temperature, salinity, rising carbon dioxide (CO2) levels; environmental signals interface endogenous signaling development (e.g. circadian clock flowering time); this integrated controls downstream responses stomatal regulation, proline metabolism, growth versus defense balance). The plasma membrane comes up frequently a site key transport events mechanosensing lipid-derived signaling, aquaporins). Adaptation extremes CO2 affects hydraulic architecture transpiration, well root shoot morphology, ways not fully understood. Environmental adaptation involves tradeoffs that limit ecological distribution crop resilience face changing increasingly unpredictable environments.

Summary Many environmental conditions fluctuate and organisms need to respond effectively. This is especially true for temperature cues that can change in minutes seasons often follow a diurnal rhythm. Plants cannot migrate most regulate their temperature. Therefore, broad array of responses have evolved deal with from freezing heat stress. A particular response mildly elevated temperatures called thermomorphogenesis, suite morphological adaptations includes thermonasty, formation thin leaves elongation growth petioles hypocotyl. Thermomorphogenesis allows optimal performance suboptimal by enhancing the cooling capacity. When rise further, stress tolerance mechanisms be induced enable plant survive stressful temperature, which typically comprises cellular protection memory thereof. Induction depend on gene expression regulation, governed diverse epigenetic processes. In this Tansley review we update current knowledge regulation signalling response, focus thermomorphogenesis memory. highlight emerging role H3K4 methylation marks pathways.

Abstract Throughout evolution, plants have developed strategies to confront and alleviate the detrimental impacts of abiotic stresses on their growth development. The combat involve intricate molecular networks a spectrum early late stress‐responsive pathways. Plant peptides, consisting fewer than 100 amino acid residues, are at forefront these responses, serving as pivotal signalling molecules. These with roles similar phytohormones, intricately regulate plant growth, development facilitate essential cell‐to‐cell communications. Numerous studies underscore significant role small peptides in coordinating diverse events triggered by environmental challenges. Originating from proteolytic processing larger protein precursors or directly translated open reading frames, including microRNA (miRNA) encoded primary miRNA, exert biological functions through binding membrane‐embedded receptor‐like kinases. This interaction initiates downstream cellular cascades, often involving major phytohormones reactive oxygen species‐mediated mechanisms. Despite advances, precise modes action for numerous other remain be fully elucidated. In this review, we delve into dynamics stress physiology, mainly focusing shedding light significance face changing conditions.
