Plants’ Response to Abiotic Stress: Mechanisms and Strategies

Abstract

Abiotic stress is the adverse effect of any abiotic factor on a plant in a given environment, impacting plants’ growth and development. These stress factors, such as drought, salinity, and extreme temperatures, are often interrelated or in conjunction with each other. Plants have evolved mechanisms to sense these environmental challenges and make adjustments to their growth in order to survive and reproduce. In this review, we summarized recent studies on plant stress sensing and its regulatory mechanism, emphasizing signal transduction and regulation at multiple levels. Then we presented several strategies to improve plant growth under stress based on current progress. Finally, we discussed the implications of research on plant response to abiotic stresses for high-yielding crops and agricultural sustainability. Studying stress signaling and regulation is critical to understand abiotic stress responses in plants to generate stress-resistant crops and improve agricultural sustainability.

Dissection of quantitative trait nucleotides and candidate genes associated with agronomic and yield-related traits under drought stress in rapeseed varieties: integration of genome-wide association study and transcriptomic analysis

“…Integration of GWAS and RNA-seq revealed 59 DEGs associated with flowering and maturity times of which the LOX4, GDSL , FAR1, NCED9, CCR2, RALFL14, DEFL7 , ORYZASIN1 , LAX2 , FY , AGL15 , AGL16 , and AGL19 genes were key flowering and maturity genes in our study. In the hormone pathway, the LOX4 , NCED9 , ORYZASIN1 , and LAX2 genes play important roles in flower development and pollen tube growth ( Caldelari et al., 2011 ; Chauvin et al., 2013 ; Huang and Han, 2014 ; Gomez et al., 2015 ; Li et al., 2018 ; Zuniga-Mayo et al., 2018 ; Park et al., 2019 ; Tran et al., 2023 ; Zhang et al., 2023d ). From the auxin carrier AUX/LAX family, LAX2 regulates the floral organ development by modulating auxin polar transport ( Cardarelli and Cecchetti, 2014 ).…”

Identification and Expression Profiling of the bZIP Gene Family Throughout the Genome in Phoebe bournei under Abiotic Stress

“…Abiotic stress has a direct impact on the growth and development of plants (Zhang et al 2023). When plants are exposed to an environment with harsh conditions that they are not able to tolerate, their normal growth and development will be affected.…”

Influence of Weather Conditions in the Northwestern Russian Federation on Flax Fiber Characters According to the Results of a 30-Year Study

“…A successful solution of this problem should be based on understanding the influence of environmental conditions on the plant growth and development. Though molecular mechanisms of plant responses to different abiotic stresses are now intensively evaluated [ 3 ], the complex influence of weather conditions still needs to be clarified. For successful crop production, it is very important to understand the environment requirements of the crop in different stages of development and, on the other hand, outline the main features that are required for the newly developed varieties to withstand unfavorable and changing weather conditions.…”
