An inter-university research group has succeeded in constructing the gene expression network behind the vascular development process in plants. They achieved this by performing bioinformatics analysis using the VISUAL tissue culture platform, which generates vascular stem cells from leaf cells. In this network, they also discovered a new BES/BZR transcription factor, BEH3, and illuminated its role in vascular cell maintenance. ....
Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful, but precisely how nitrate presence controls nodule formation in these plants has been a mystery. ....
Price: Researchers from the University of Tsukuba find that nitrate-induced control of root nodule formation results from varying DNA-binding properties of specific proteins that control gene expression Tsukuba, Japan - Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how nitrate presence controls nodule formation in these plants has been a mystery. Now, researchers from Japan have found that interactions between proteins and nitrate can induce and repress genes, controlling nodulation with potential applications in sustainable agriculture. In a study published in April in ....
