Gene networks involved in drought stress response and tolerance

TLDR
In this paper, a short review of recent progress resulting from analysis of gene expression during the drought-stress response in plants as well as in elucidating the functions of genes implicated in the stress response and/or stress tolerance are summarized.
Abstract
Plants respond to survive under water-deficit conditions via a series of physiological, cellular, and molecular processes culminating in stress tolerance. Many drought-inducible genes with various functions have been identified by molecular and genomic analyses in Arabidopsis, rice, and other plants, including a number of transcription factors that regulate stress-inducible gene expression. The products of stress-inducible genes function both in the initial stress response and in establishing plant stress tolerance. In this short review, recent progress resulting from analysis of gene expression during the drought-stress response in plants as well as in elucidating the functions of genes implicated in the stress response and/or stress tolerance are summarized. A description is also provided of how various genes involved in stress tolerance were applied in genetic engineering of dehydration stress tolerance in transgenic Arabidopsis plants.

Photosynthesis under drought and salt stress: regulation mechanisms from whole plant to cell

TL;DR: It is becoming apparent that plants perceive and respond to drought and salt stresses by quickly altering gene expression in parallel with physiological and biochemical alterations; this occurs even under mild to moderate stress conditions.

Drought, salt, and temperature stress-induced metabolic rearrangements and regulatory networks

TL;DR: Information about metabolic regulation in response to drought, extreme temperature, and salinity stress is summarized and the signalling events involved in mediating stress-induced metabolic changes are presented.

The effect of drought and heat stress on reproductive processes in cereals.

TL;DR: The results achieved so far indicate that various plant organs, in a definite hierarchy and in interaction with each other, are involved in determining crop yield under stress.

The interaction of plant biotic and abiotic stresses: from genes to the field

TL;DR: This review aims to characterize the interaction between biotic and abiotic stress responses at a molecular level, focusing on regulatory mechanisms important to both pathways.

Reactive oxygen species, abiotic stress and stress combination.

TL;DR: ROS is beneficial to plants during abiotic stress enabling them to adjust their metabolism and mount a proper acclimation response, as long as cells maintain high enough energy reserves to detoxify ROS.

Functional analysis

Journal ArticleDOI

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.

A gene expression map of Arabidopsis thaliana development

TL;DR: Examining the expression patterns of large gene families, it is found that they are often more similar than would be expected by chance, indicating that many gene families have been co-opted for specific developmental processes.

Drought and Salt Tolerance in Plants

TL;DR: The responses of plants to salt and water stress are described, the regulatory circuits which allow plants to cope with stress are presented, and how the present knowledge can be applied to obtain tolerant plants is discussed.

A novel cis-acting element in an Arabidopsis gene is involved in responsiveness to drought, low-temperature, or high-salt stress.

TL;DR: The rd29A promoter in both transgenic Arabidopsis and tobacco was analyzed and a novel cis-acting, dehydration-responsive element (DRE) containing 9 bp, TACCGACAT, was identified that is involved in the first rapid response of rd 29A to conditions of dehydration or high salt.
