DREB2 (dehydration-responsive element-binding factor 2)-type transcription factors play a critical role in the stress-related regulation network in plants. In this study, we isolated and characterized a DREB2 homolog from Malus sieversii Roem., designated MsDREB2C (GenBank accession No. JQ790526). MsDREB2C localized to the nucleus and transactivated reporter genes in yeast strain YGR-2. Quantit...

bHLH (basic helix-loop-helix) transcription factors play important roles in the abiotic stress response in plants, but their characteristics and functions in tartary buckwheat (Fagopyrum tataricum), a flavonoid-rich cereal crop with a strong stress tolerance, have not been fully investigated. Here, a novel bHLH gene, designated FtbHLH3, was isolated and characterized. Expression analysis in tar...

Plants in nature may face a wide range of favorable or unfavorable biotic and abiotic factors during their life cycle. Any of these factors may cause stress in plants; therefore, they have to be more adaptable to stressful environments and must acquire greater response to different stresses. The objective of this study is to retrieve and arrange data from the literature in a standardized electr...

To elucidate the effects of high temperatures, wheat plants (Triticum aestivum cv. CPAN 1676) were given heat shocks at 37°C and 42°C for two hours, and responsive genes were identified through PCR-Select Subtraction technology. Four subtractive cDNA libraries, including three forward and one reverse subtraction, were constructed from three different developmental stages. A total of 5500 ESTs w...

Extensive studies in Arabidopsis and rice have demonstrated that Subgroup-A members of the bZIP transcription factor family play important roles in plant responses to multiple abiotic stresses. Although common wheat (Triticum aestivum) is one of the most widely cultivated and consumed food crops in the world, there are limited investigations into Subgroup A of the bZIP family in wheat. In this ...

Abiotic stress negatively affects the yield of many crops. The SQUAMOSA promoter binding protein-like proteins (SBPs) represent a family plant-specific transcription factors which play essential roles in plant growth, development, and responsiveness. In this study, 18 putative SBPs (PgSBPs) were identified genome pearl millet on basis SBP domain. One or two zinc finger-like structure(s) nuclear...

BACKGROUND AND AIMS Corn (Zea mays) responds to salt stress via changes in gene expression, metabolism and physiology. This adaptation is achieved through the regulation of gene expression at the transcriptional and post-transcriptional levels. MicroRNAs (miRNAs) have been found to act as key regulating factors of post-transcriptional gene expression. However, little is known about the role of ...

BACKGROUND Calcium-binding proteins that contain EF-hand motifs have been reported to play important roles in transduction of signals associated with biotic and abiotic stresses. To functionally characterize genes of EF-hand family in response to abiotic stress, an MtCaMP1 gene belonging to EF-hand family from legume model plant Medicago truncatula was isolated and its function in response to d...

Crop plants are subjected to multiple abiotic stresses during their lifespan that greatly reduce productivity and threaten global food security. Recent research suggests that plants can be primed by chemical compounds to better tolerate different abiotic stresses. Chemical priming is a promising field in plant stress physiology and crop stress management. We review here promising chemical agent...

The cysteine2/histidine2-type zinc finger proteins are a large family of transcription regulators, and some of them play essential roles in plant responses to biotic and abiotic stress. In this study, we found that expression of C2H2-type ZINC FINGER OF ARABIDOPSIS THALIANA6 (AtZAT6) was transcriptionally induced by salt, dehydration, cold stress treatments, and pathogen infection, and AtZAT6 w...
