Three DREB homologue genes, GmDREBa,GmDREBb, and GmDREBc, were isolated from soybean, Glycine max (L.) Merr. Each of the deduced proteins contains an AP2 domain of 64 amino acids. Yeast one-hybrid assay revealed that all of the three dehydration-responsive, element-binding proteins specifically bound to the dehydration-responsive element. Analysis of(More)
Cation transport is thought to be an important process for ion homeostasis in plant cells. Here, we report that a soybean putative cation/proton antiporter GmCAX1 may be a mediator of this process. GmCAX1 is expressed in all tissues of the soybean plants but at a lower level in roots. Its expression was induced by PEG, ABA, Ca2+, Na+ and Li+ treatments. The(More)
By using cDNA-AFLP, we analyzed a recombinant inbred line population of soybean that was derived from a soybean mosaic virus (SMV) resistant cultivar Kefeng No.1 and a susceptible cultivar Nannong 1138-2. One hundred and eight fragments showing polymorphism between SMV resistant and susceptible pools were identified. One fragment w27 was 96 bp in length and(More)
A full-length gene GmPti1 was identified from soybean in an EST sequencing project by its homology to tomato Pti1. It encoded a protein of 366 amino acids. RT-PCR analysis showed that the GmPti1 expression was induced by salicylic acid and wounding. The deduced amino acid sequence had a Ser/Thr/Tyr kinase domain. GmPti1 protein was expressed in E. coli as(More)
Hypoxia inducible factor 1 alpha (HIF-1 alpha) is a basic helix-loop-helix-PAS (bHLH-PAS) transcription factor that mediates certain cellular responses to low oxygen tension, iron chelators, Co2+, Ni2+, Mg2+, and low intracellular glucose concentration. Upon exposure to the above conditions, HIF-1 alpha is upregulated and heterodimerizes with the Ah(More)
Cell division is a fundamental biological process sharing conserved features and controls in all eukaryotes. The cell cycle is usually divided into four phases: G1, S, G2, and M. Regulated gene expression is an important mechanism for controlling cell cycle progression and genes involved in cell division-related processes often show transcriptional(More)
