TLDR
An Arabidopsis thaliana RD20 cDNA encodes a putative protein with a conserved EF-hand Ca2+-binding domain that was induced not only by drought but also by ABA and high salinity.Abstract:
An Arabidopsis thaliana RD20 cDNA, which was isolated as one of drought-inducible genes, encodes a putative protein with a conserved EF-hand Ca2+-binding domain. The recombinant RD20 protein was shown to bind Ca2+. The transcription of RD20 gene was induced not only by drought but also by ABA and high salinity.read more

Abscisic Acid Signaling in Seeds and Seedlings
TL;DR: Abscisic acid regulates many agronomically important aspects of plant development, including the synthesis of seed storage proteins and lipids, the promotion of seed desiccation tolerance and dormancy, and the inhibition of the phase transitions from embryonic to germinative growth and from.

Arabidopsis AtMYC2 (bHLH) and AtMYB2 (MYB) Function as Transcriptional Activators in Abscisic Acid Signaling
TL;DR: Results indicate that both AtMYC2 and AtMYB2 proteins function as transcriptional activators in ABA-inducible gene expression under drought stress in plants.

TL;DR: The results show that the full-length cDNA microarray is a useful material with which to analyze the expression pattern of Arabidopsis genes under drought and cold stresses, to identify target genes of stress-related transcription factors, and to identify potential cis-acting DNA elements by combining the expression data with the genomic sequence data.

TL;DR: It is found that the expression of sense TUs is necessary for the stress- or ABA-inducible expression of the antisense TUs in the fSATs (AGI code/non-AGI TU).

TL;DR: A new criterion for triggering the extension of word hits, combined with a new heuristic for generating gapped alignments, yields a gapped BLAST program that runs at approximately three times the speed of the original.

The molecular basis of dehydration tolerance in plants
J. Ingram,Dorothea Bartels +1 more
TL;DR: A large number of genes with a potential role in drought tolerance have been described, and major themes in the molecular response have been established.

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.

Plant responses to water deficit
TL;DR: It has been difficult to resolve the functions of many drought-induced genes against the background of other stress-induced changes, and thus it is now important to integrate information about cellular and whole plant responses.

Gene expression and signal transduction in water-stress response
TL;DR: Findings suggest the existence of both ABAindependent and ABA-dependent signal transduction cascades between the initial signal of drought or cold stress and the expression of specific genes, which are consistent with evidence that these genes respond to water stress or dehydration.
