Abstract: Plants cannot move, so they must endure abiotic stresses such as drought, salinity and extreme temperatures. These stressors greatly limit the distribution of plants, alter their growth and development, and reduce crop productivity. Recent progress in our understanding of the molecular mechanisms underlying the responses of plants to abiotic stresses emphasizes their multilevel nature; multiple processes are involved, including sensing, signalling, transcription, transcript processing, translation and post-translational protein modifications. This improved knowledge can be used to boost crop productivity and agricultural sustainability through genetic, chemical and microbial approaches.

Dajo Smet,Helder Opdebeeck,Klaas Vandepoele +2 more
TL;DR: Predicting transcriptional responses to heat and drought stress in rice using genomic features and machine learning models. The study explores the use of machine learning to predict gene expression in rice in response to heat or drought stress. The findings provide insights into the regulatory code underlying the transcriptional response to abiotic stress and contribute to the development of novel strategies to improve crop resilience.
Molecular mechanism of drought resistance in soybean roots revealed using physiological and multi-omics analyses.

Salt and drought stress signal transduction in plants
TL;DR: Salt and drought stress signal transduction consists of ionic and osmotic homeostasis signaling pathways, detoxification (i.e., damage control and repair) response pathways, and pathways for growth regulation.
Abiotic Stress Signaling and Responses in Plants
TL;DR: Core stress-signaling pathways involve protein kinases related to the yeast SNF1 and mammalian AMPK, suggesting that stress signaling in plants evolved from energy sensing.

Plant-growth-promoting rhizobacteria.
TL;DR: This review restricts itself to bacteria that are derived from and exert this effect on the root and generally designated as PGPR (plant-growth-promoting rhizobacteria), which can be direct or indirect in their effects on plant growth.

PLANT COLD ACCLIMATION: Freezing Tolerance Genes and Regulatory Mechanisms
Michael F. Thomashow
- 01 Jun 1999
TL;DR: This review of recent advances in determining the nature and function of genes with roles in freezing tolerance and the mechanisms involved in low temperature gene regulation and signal transduction concludes that cold acclimation includes the expression of certain cold-induced genes that function to stabilize membranes against freeze-induced injury.
Two transcription factors, DREB1 and DREB2, with an EREBP/AP2 DNA binding domain separate two cellular signal transduction pathways in drought- and low-temperature-responsive gene expression, respectively, in Arabidopsis.

TL;DR: Overexpression of the DREB1A cDNA in transgenic Arabidopsis plants not only induced strong expression of the target genes under unstressed conditions but also caused dwarfed phenotypes in the transgenic plants, and revealed freezing and dehydration tolerance.
