Root system architecture plasticity is the key trait for drought stress adaptation in plants

Towards climate-resilient rice (Oryza sativa L.): re-engineering root system architecture for abiotic stress tolerance: a review

This review synthesizes the current understanding of RSA in rice as a dynamic trait complex that integrates root spatial configuration, developmental processes, anatomical features, and physiological functions, collectively influencing abiotic stress tolerance to enable the development of climate-resilient rice varieti...

Root Plasticity and Hormonal Regulation Shape Alfalfa Cultivar Responses to Drought and Waterlogging

Alfalfa ( Medicago sativa L.) is a globally strategic forage legume whose productivity is increasingly threatened by climatic variability, particularly recurrent drought and flooding events. Although both stresses disrupt plant water balance, they impose contrasting physiological constraints that require dist...

Plant growth-promoting rhizobacteria as a soil-based strategy to improve nutrient acquisition and drought tolerance in sugarcane

Drought is an increasingly important constraint to sustainable sugarcane production because prolonged water deficit can impair root development, nutrient acquisition, photosynthesis, biomass accumulation, sucrose accumulation, and ultimately cane and sugar yield. Plant growth-promoting rhizobacteria (PGPR) have emerged...

Harnessing the variability in root architecture and VsNGR gene expression for drought adaptation in common vetch.

Root system architecture (RSA) is a key determinant of drought adaptation, particularly in rainfed crops such as common vetch (Vicia sativa L.). This study evaluated RSA traits together with shoot and root biomass in seedlings of 27 vetch genotypes from six countries under control conditions and water stress induced by...

Silicon-mediated mitigation of drought stress in crops: current understanding and future perspectives

The selection of drought-tolerant plant genotypes in Iraq

Water stress plays a critical role in plant growth and productivity, particularly in crops like maize. Water stress (or drought) can significantly affect plant physiology and development. Absorption vs. loss: Plants absorb water through their roots, but during water stress, the rate of water loss through transpiration...
