abiotic stress such as cold and drought has adverse effects on plants growth and development. abiotic stress resistance is one of the most important goals in plant breeding. this goal can be achieved through transcription factor gene transfer to plants. recent studies show many successes in improving abiotic stress resistance by use of transcription factor gene transfer. the objective of the re...

Due to adverse effects of abiotic stresses on plant growth and development, we focused on an effective abiotic stress responsive element known as Dehydration responsive element binding factor (DREB) in Triticum aestivum. The objective of the research was to isolate and molecularly characterize two wheat DREB2 (WDREB2) gene isoforms. In order to isolate WDREB2 isoforms, plants were exposed to co...

The APETALA 2/Ethylene-responsive element binding factor (AP2/ERF) transcription factor gene family is widely involved in the biotic and abiotic stress regulation. Haynaldia villosa (VV, 2n = 14), a wild species of wheat, is a potential gene pool for wheat improvement. H. villosa confers high resistance to several wheat diseases and high tolerance to some abiotic stress. In this study, ERF1-V, ...

Abiotic stresses such as cold, drought and high salinity are common adverse environmental conditions that seriously influence plant growth and crop productivity worldwide. Some transcription factors (TFs) have been isolated and verified recently to play roles under abiotic stresses. Among them, the TF of DREB (Dehydration responsive element binding) can therefore regulate the expression of many...

The DREB (dehydration-responsive element binding)-type transcription factors regulate the expression of stress-inducible genes by binding the DRE/CRT cis-elements in promoter regions. The upstream transcription factors that regulate the transcription of DREB transcription factors have not been clearly defined, although the function of DREB transcription factors in abiotic stress is known. In th...

Plants are continuously exposed to a myriad of abiotic and biotic stresses. However, the molecular mechanisms by which these stress signals are perceived and transduced are poorly understood. To begin to identify primary stress signal transduction components, we have focused on genes that respond rapidly (within 5 min) to stress signals. Because it has been hypothesized that detection of physic...

The dehydration responsive element binding (DREB) transcription factors play an important role in regulating stress-related genes. OsDREB2A, a member of the DREBP subfamily of AP2/ERF transcription factors in rice (Oryza sativa), is involved in the abiotic stress response. OsDREB2A expression is induced by drought, low-temperature and salt stresses. Here, we report the ability of OsDREB2A to re...

Chickpea (Cicer arietinum L.) is an important food legume crop, particularly for the arid regions including Indian subcontinent. Considering the detrimental effect of drought, temperature and salt stress on crop yield, efforts have been initiated in the direction of developing improved varieties and designing alternate strategies to sustain chickpea production in adverse environmental condition...

The dehydration-responsive element binding (DREB) transcription factors binds to dehydration responsive element (DRE)/C-repeat (CRT) cis-element, induces a set of abiotic stress-related genes and imparts stress endurance to plants. In the present study, a DREB1 like gene, designated as LlDREB1A, was isolated from highly cold adapted ecotype of Lepidium latifolium L. Its full-length cDNA (JN5615...

Remorin proteins (REMs) form a plant-specific protein family, with some REMs being responsive to abiotic stress. However, the precise functions of REMs in abiotic stress tolerance are not clear. In this study, we identified 11 remorin genes from foxtail millet (Setaria italica) and cloned a remorin gene, SiREM6, for further investigation. The transcript level of SiREM6 was increased by high sal...
