The complexity of environmental conditions encountered by plants in the field, or nature, is gradually increasing due to anthropogenic activities that promote global warming, climate change, and increased levels pollutants. While past it seemed sufficient study how acclimate one even two different stresses affecting them simultaneously, complex developing on our planet necessitate a new approach studying stress plants: Acclimation multiple occurring concurrently consecutively (termed, multifactorial combination [MFSC]). In an initial plant response MFSC, conducted with Arabidopsis thaliana seedlings subjected MFSC six abiotic stresses, was found increase number simultaneously impacting plant, growth survival declined, if effects each involved such minimal insignificant. three recent studies, crop plants, have similar commercial rice cultivar, maize hybrid, tomato, soybean, causing significant reductions growth, biomass, physiological parameters, and/or yield traits. As are worsening, as well becoming more complex, addressing its agriculture ecosystems worldwide becomes high priority. this review, we address crops, agriculture, worldwide, highlight potential avenues enhance resilience crops MFSC.

Systemic stomatal responses in plants: Coordinating development, stress, and pathogen defense under a changing climate

Plant Cell & Environment, Journal Year: 2024, Volume and Issue: 47(4), P. 1171 - 1184

Published: Jan. 1, 2024

Abstract To successfully survive, develop, grow and reproduce, multicellular organisms must coordinate their molecular, physiological, developmental metabolic responses among different cells tissues. This process is mediated by cell‐to‐cell, vascular and/or volatile communication, involves electric, chemical hydraulic signals. Within this context, stomata serve a dual role coordinating to the environment with neighbouring at epidermis, but also other present on parts of plant. As represent one most important conduits between plant its above‐ground environment, as well directly affect photosynthesis, respiration status controlling gas vapour exchange atmosphere, overall response within leaves tissues plays cardinal in growth, development reproduction. Here, we discuss examples local systemic stomatal coordination, signalling pathways that mediate them, importance coordination our food supply, ecosystems weather patterns, under changing climate. We further potential biotechnological implications regulating for enhancing agricultural productivity warmer CO 2 ‐rich environment.

Improvement in genomic prediction of maize with prior gene ontology information depends on traits and environmental conditions

The Plant Genome, Journal Year: 2025, Volume and Issue: 18(1)

Published: Jan. 8, 2025

Abstract Classical genomic prediction approaches rely on statistical associations between traits and markers rather than their biological significance. Biologically informed selection of regions can help prioritize polymorphisms by considering underlying processes, making models robust accurate. Gene ontology (GO) terms be used for this purpose, the information integrated into through marker categorization. It allows likely causal to account a certain portion genetic variance independently from remaining markers. We systematically tested list 5110 GO predictive performance physiological (platform traits) productivity (field grain yield) in maize ( Zea mays L.) panel using features best linear unbiased (GFBLUP) model. Predictive abilities were compared classical (GBLUP). gains with categorizing based given term strongly depend trait growth conditions, as useful condition or somewhat similar conditions but not same different condition. Overall, results all GFBLUP GBLUP show that former might less efficient latter. Even though we could identify prior criterion determine which offer benefit trait, posteriori find interpretations results, meaning helpful if more about gene functions relationships was known.

Plants are frequently exposed to different combinations of soil constraints including salinity and herbicides. These abiotic conditions negatively affect photosynthesis, growth plant development resulting in limitations agriculture production. To respond these conditions, plants accumulate metabolites that restore cellular homeostasis key for stress acclimation processes.
