Methods and concepts in quantifying resistance to drought, salt and freezing, abiotic stresses that affect plant water status.
The abiotic stresses of drought, salinity and freezing are linked by the fact that they all decrease the availability of water to plant cells. This decreased availability of water is quantified as aExpand

Endogenous siRNAs Derived from a Pair of Natural cis-Antisense Transcripts Regulate Salt Tolerance in Arabidopsis
In higher eukaryotes, miRNAs and siRNAs guide translational inhibition, mRNA cleavage, or chromatin regulation. We found that the antisense overlapping gene pair of Delta(1)-pyrroline-5-carboxylateExpand

Cold stress regulation of gene expression in plants.
Cold stress adversely affects plant growth and development. Most temperate plants acquire freezing tolerance by a process called cold acclimation. Here, we focus on recent progress inExpand

The Arabidopsis NFYA5 Transcription Factor Is Regulated Transcriptionally and Posttranscriptionally to Promote Drought Resistance[W]
Nuclear factor Y (NF-Y) is a ubiquitous transcription factor composed of three distinct subunits (NF-YA, NF-YB, and NF-YC). We found that the Arabidopsis thaliana NFYA5 transcript is strongly inducedExpand

Salt Cress. A Halophyte and Cryophyte Arabidopsis Relative Model System and Its Applicability to Molecular Genetic Analyses of Growth and Development of Extremophiles1
Salt cress (Thellungiella halophila) is a small winter annual crucifer with a short life cycle. It has a small genome (about 2 × Arabidopsis) with high sequence identity (average 92%) withExpand

Role of miRNAs and siRNAs in biotic and abiotic stress responses of plants.
Small, non-coding RNAs are a distinct class of regulatory RNAs in plants and animals that control a variety of biological processes. In plants, several classes of small RNAs with specific sizes andExpand

Small RNAs as big players in plant abiotic stress responses and nutrient deprivation.
Abiotic stress is one of the primary causes of crop losses worldwide. Much progress has been made in unraveling the complex stress response mechanisms, particularly in the identification of stressExpand

Heat stress induction of miR398 triggers a regulatory loop that is critical for thermotolerance in Arabidopsis.
microRNAs (miRNAs) play important roles in plant growth and development. Previous studies have shown that down-regulation of miR398 in response to oxidative stress permits up-regulation of one of itsExpand

A DEAD Box RNA Helicase Is Essential for mRNA Export and Important for Development and Stress Responses in Arabidopsis
An Arabidopsis thaliana mutant, cryophyte, was isolated and found to have an enhanced cold stress-induction of the master regulator of cold tolerance, C-repeat binding factor 2 (CBF2), and itsExpand

The plasma membrane Na+/H+ antiporter SOS1 interacts with RCD1 and functions in oxidative stress tolerance in Arabidopsis
The adverse effects of high salt on plants include Na+ toxicity and hyperosmotic and oxidative stresses. The plasma membrane-localized Na+/H+ antiporter SOS1 functions in the extrusion of toxic Na+Expand
