The understanding of stomatal regulation in climate stress is essential for ensuring resilient crops. investigation the combined heat and drought aimed to link effects exogenous melatonin on conductance (gs) its mechanistic interactions with ABA or ROS signaling. Melatonin-treated non-treated tomato seedlings were subjected moderate severe levels (38°C one three days) (soil relative water content 50% 20%) applied individually combination. We measured gs, anatomy, metabolites enzymatic scavengers. stomata responded predominantly at soil (SRWC) = SRWC 20%. Drought increased stress, whereas caused an accumulation conjugated form, glucose ester, both stress. treatment affected gs activity scavenging enzymes but had no effect levels. metabolism conjugation might play a role opening toward high temperatures. provide evidence that increases not mediated through

Over the years, changes in agriculture industry have been inevitable, considering need to feed growing population. As world population continues grow, food security has become challenged. Resources such as arable land and freshwater scarce due quick urbanization developing countries anthropologic activities; expanding agricultural production areas is not an option. Environmental climatic factors drought, heat, salt stresses pose serious threats worldwide. Therefore, utilize remaining water effectively efficiently maximize yield support increasing demand crucial. It essential develop climate-resilient crops that will outperform traditional under any abiotic stress conditions salt, well these combinations.

Physiological Responses of Plants to Combined Drought and Heat under Elevated CO2

Agronomy, Journal Year: 2022, Volume and Issue: 12(10), P. 2526 - 2526

Published: Oct. 16, 2022

Anthropogenic activities over the last century have caused rapid changes in environmental conditions through increasing CO2 emissions atmosphere that contribute to global warming. Moreover, increased average temperature is linked with precipitation rate and distribution, resulting a negative impact on crop health productivity. Plants nature often experience combined stresses; therefore, they developed adaptive mechanisms cope fluctuating conditions. Thus, investigating plant responses under unfavorable will provide better understanding of how crops can adapt thereby assist selecting climate-resilient withstand climate variability. This review highlights main physiological biochemical grown elevated (eCO2) exposed abiotic stresses (drought heat). mitigation limitation plants combination stress discussed.

Stomatal effects and ABA metabolism mediate differential regulation of leaf and flower cooling in tomato cultivars exposed to heat and drought stress

Journal of Experimental Botany, Journal Year: 2024, Volume and Issue: 75(7), P. 2156 - 2175

Published: Jan. 9, 2024

Abstract Co-occurring heat and drought stresses challenge crop performance. Stomata open to promote evaporative cooling during stress, but close retain water which resulted in complex stomatal regulation under combined drought. We aimed investigate leaves flowers of perennial, indeterminate cultivars tomatoes subjected individual stress followed by a recovery period, measuring morphological, physiological, biochemical factors involved regulation. Under stomata were predominantly affected drought, with lower density closing, resulting significantly decreased photosynthesis higher leaf temperature. Conversely, sepals seemed mainly stress. The differential patterns persisted into the phase as contrasting density. show that flower transpiration is regulated temperature, soil availability Organ-specific development abscisic acid metabolism mediated this phenomenon. Our results throw light on dual role tolerance vegetative generative organs, demonstrate importance considering surfaces phenotyping reactions

Drought priming‐induced stress memory improves subsequent drought or heat tolerance via activation of γ‐aminobutyric acid‐regulated pathways in creeping bentgrass

Plant Biology, Journal Year: 2024, Volume and Issue: unknown

Abstract Recurrent drought can induce stress memory in plants to tolerance subsequent stress, such as high temperature or drought. Drought priming (DP) is an effective approach improve various stresses; however, the potential mechanism of DP‐induced has not been fully resoved. We examined DP‐regulated thermotolerance associated with changes physiological responses, GABA and NO metabolism, heat shock factor (HSF) dehydrin (DHN) pathways perennial creeping bentgrass. Plants recover after two cycle DP, DP‐treated had significantly higher leaf RWC, Chl content, photochemical efficiency, cell membrane stability. DP alleviated oxidative damage through enhancing total antioxidant capacity response stress. Endogenous was increased by activating glutamic acid decarboxylase activity inhibiting transaminase activity. also enhanced accumulation NO, depending on NOS activity, under Transcript levels multiple transcription factors, proteins, DHNs HSF DHN were up‐regulated but there differences between these pathways. The findings indicate that recurrent moderate drought, improves relation GABA‐regulated pathways, providing new insight into understanding role plant adaptation complex environmental stresses.

Elevated [CO2] negatively impacts C4 photosynthesis under heat and water stress without penalizing biomass

Journal of Experimental Botany, Journal Year: 2023, Volume and Issue: 74(9), P. 2875 - 2890

Published: Feb. 17, 2023

Elevated [CO2] (eCO2) and water stress reduce leaf stomatal conductance (gs), which may affect thermoregulation during heat waves (heat stress). Two sorghum lines, with different width were grown in a glasshouse at mean day temperature of 30 °C, under watering levels, subjected to (43 °C) for 6 d the start reproductive stage. We measured photosynthetic responses light transients before harvesting plants. Photosynthesis growth conditions (Agrowth) biomass accumulation enhanced by eCO2 control conditions. Heat increased gs, especially wider leaves, reduced time constant opening (kopen) ambient but not eCO2. However, photosynthesis due evaporative cooling. prevented reduction both stress, possibly improved plant soil status as result gs. Our results suggest that response C4 crop future climate depends on trade-off between low gs needed high use efficiency drought tolerance, tolerance an future.
