Abstract Abiotic stresses such as drought and heat continue to impact crop production in a warming world. This review distinguishes seven inherent capacities that enable plants respond abiotic growing, although at reduced rate, achieve productive yield. These are the selectively take up essential resources, store them supply different plant parts, generate energy required for cellular functions, conduct repairs maintain tissues, communicate between manage existing structural assets face of changed circumstances, shape-shift through development be efficient environments. By illustration, we show how all important reproductive success major species during drought, salinity, temperature extremes, flooding, nutrient stress.

Published: May 1, 2024

Drought is a natural disaster that has profound impact on global agricultural production, significantly reduces crop yields and thereby poses severe threat to worldwide food security. Addressing the challenge of effectively improving drought resistance (DR) mitigate yield loss under conditions issue. An optimal root system architecture (RSA) plays pivotal role in enhancing crops' capacity efficiently uptake water nutrients, which consequently strengthens their resilience against environmental stresses. In this review, we discuss compositions roles RSA summarize most recent developments augmenting tolerance crops by manipulating RSA-related genes. Based current research, propose potential configuration could be helpful DR. Lastly, discussed existing challenges future directions for breeding with enhanced DR capabilities through genetic improvements targeting RSA.

Regulatory Dynamics of Plant Hormones and Transcription Factors under Salt Stress

Biology, Journal Year: 2024, Volume and Issue: 13(9), P. 673 - 673

Published: Aug. 29, 2024

The negative impacts of soil salinization on ion homeostasis provide a significant global barrier to agricultural production and development. Plant physiology biochemistry are severely affected by primary secondary NaCl stress impacts, which damage cellular integrity, impair water uptake, trigger physiological drought. Determining how transcriptional factors (TFs) hormone networks regulated in plants response salt is necessary for developing crops that tolerate salt. This study investigates the complex mechanisms several TF families influence plant responses stress, involving AP2/ERF, bZIP, NAC, MYB, WRKY. It demonstrates these transcription help respond detrimental effects salinity modulating gene expression through including signaling, osmotic pathway activation, homeostasis. Additionally, it explores hormonal imbalances triggered entail interactions among phytohormones like jasmonic acid (JA), salicylic (SA), abscisic (ABA) within regulatory networks. review highlights role key salt-stress response, their interaction with hormones crucial genome-edited can enhance sustainability address food security challenges.

Root responses to abiotic stress: a comparative look at root system architecture in maize and sorghum

Journal of Experimental Botany, Journal Year: 2023, Volume and Issue: 75(2), P. 553 - 562

Published: Oct. 4, 2023

Abstract Under all environments, roots are important for plant anchorage and acquiring water nutrients. However, there is a knowledge gap regarding how root architecture contributes to stress tolerance in changing climate. Two closely related species, maize sorghum, have distinct system architectures different levels of tolerance, making comparative analysis between these two species an ideal approach resolve this gap. current research has focused on shared aspects the that advantageous under abiotic conditions rather than differences. Here we summarize state comparing relative performance deficit, salt stress, low phosphorus sorghum. steeper angles deeper systems proposed be both species.

Journal of Agronomy and Crop Science, Journal Year: 2024, Volume and Issue: 210(6)

Published: Oct. 10, 2024

ABSTRACT Cereal crops are cultivated across diverse regions globally, facing numerous environmental challenges, with salinity posing a significant threat to their growth and productivity. Plants respond stress (SS) through various morphological physiological mechanisms. Notably, root system architecture (RSA) has emerged as crucial factor in aiding nutrient uptake ensuring efficient water supply, reshaping plant responses, particularly under SS. However, assessing visualizing RSA patterns different is more challenging than aboveground parts, often leading neglect research. Roots serve dual role SS: preventing Na + (sodium) from soil its accumulation into shoots. This review highlights the impact of SS on remodeling RSA, encompassing phenology, cytology, genetic regulation. It offers comprehensive insights architecture, functionalities, hormonal crosstalk, agronomic strategies tailored for cereals crops. These aim optimize resource capture, mitigate uptake—known reduce yield saline conditions—and explore potential avenues engineering roots circumvent
