Low temperature is an important environmental factor influencing plant growth and development. In this study, we report the characterization of a genetic locus, HOS2, which is defined by three Arabidopsis thaliana mutants. The hos2-1, hos2-2 and hos2-3 mutations result in enhanced expression of RD29A and other stress genes under low temperature treatment. Gene expression in response to osmotic ...

Low water availability is the major environmental factor limiting growth and productivity of plants and crops and is therefore considered of high importance for agriculture affected by climate change. Identifying regulatory components controlling the response and tolerance to drought stress is thus of major importance. The NAC transcription factor (TF) JUNGBRUNNEN1 (JUB1) from Arabidopsis thali...

We produced transgenic Arabidopsis plants that express chimeric genes for transcription factors converted to dominant repressors, using Chimeric REpressor gene-Silencing Technology (CRES-T), and evaluated the salt tolerance of each line. The seeds of the CRES-T lines for ADA2b, Msantd, DDF1, DREB26, AtGeBP, and ATHB23 exhibited higher germination rates than Wild type (WT) and developed rosette ...

Drought stress critically endangers the growth and development of crops. Glutathione S-transferase plays a vital role in response to abiotic stress. However, there are few studies on glutathione maize drought In this study, significantly downregulated expression ZmGST26 roots under was analyzed by qRT-PCR. Promoter analyses showed that were several cis-acting elements related involved oxidative...

DREB (dehydration-responsive element-binding protein) transcription factors have important roles in the stress-related regulation network in plants. A DREB orthologue, GmDREB3, belonging to the A-5 subgroup of the DREB subfamily, was isolated from soybean using the RACE (rapid amplification of cDNA ends) method. Northern blot analysis showed that expression of GmDREB3 in soybean seedlings was i...

Engineering transcription factors (TF) hold promise in enhancing abiotic stress tolerance plants. In this study, one of the popular rice varieties South India, namely ADT 43, was engineered with a TF AtDREB1A driven by stress-inducible rd29A promoter. PCR and Southern hybridization were employed to confirm integration copy number transgene. Transgenic lines (T1) 43 showed enhanced drought salin...
