Cell Signaling during Cold, Drought, and Salt Stress Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.000596.
Low temperature, drought, and high salinity are common stress conditions that adversely affect plant growth and crop production. The cellular and molecular responses of plants to environmental stressExpand

The Arabidopsis HOS1 gene negatively regulates cold signal transduction and encodes a RING finger protein that displays cold-regulated nucleo--cytoplasmic partitioning.
Low temperature is one of the most important environmental stimuli that control gene transcription programs and development in plants. In Arabidopsis thaliana, the HOS1 locus is a key negativeExpand

The Arabidopsis LOS5/ABA3 Locus Encodes a Molybdenum Cofactor Sulfurase and Modulates Cold Stress– and Osmotic Stress–Responsive Gene Expression
To understand low temperature and osmotic stress signaling in plants, we isolated and characterized two allelic Arabidopsis mutants, los5-1 and los5-2, which are impaired in gene induction by coldExpand

Genetic Analysis of Salt Tolerance in Arabidopsis: Evidence for a Critical Role of Potassium Nutrition
A large genetic screen for sos (for salt overly sensitive) mutants was performed in an attempt to isolate mutations in any gene with an sos phenotype. Our search yielded 28 new alleles of sos1, nineExpand

Genetic analysis of osmotic and cold stress signal transduction in Arabidopsis: interactions and convergence of abscisic acid-dependent and abscisic acid-independent pathways.
To dissect genetically the complex network of osmotic and cold stress signaling, we constructed lines of Arabidopsis plants displaying bioluminescence in response to low temperature, drought,Expand

FIERY1 encoding an inositol polyphosphate 1-phosphatase is a negative regulator of abscisic acid and stress signaling in Arabidopsis.
The plant hormone abscisic acid (ABA) plays a wide range of important roles in plant growth and development, including embryogenesis, seed dormancy, root and shoot growth, transpiration, and stressExpand

A calcium sensor and its interacting protein kinase are global regulators of abscisic acid signaling in Arabidopsis.
The phytohormone abscisic acid (ABA) triggers an oscillation in the cytosolic Ca(2+) concentration, which is then perceived by unknown Ca(2+) binding proteins to initiate a series of signalingExpand

Regulation of Osmotic Stress-responsive Gene Expression by theLOS6/ABA1 Locus inArabidopsis *
Drought and high salinity induce the expression of many plant genes. To understand the signal transduction mechanisms underlying the activation of these genes, we carried out a genetic screen toExpand

LOS2, a genetic locus required for cold‐responsive gene transcription encodes a bi‐functional enolase
The Arabidopsis mutation, los2, impairs cold‐responsive gene transcription, acquired freezing tolerance and plant resistance to chilling under certain conditions. LOS2 was isolated through positionalExpand
