A big congratulations to Dr. Abidur Rahman and his PhD student Mohammad Arif Ashraf for their recent article on cold stress response in Arabidopsis thaliana publihed in the prestigious journal "the plant journal". Dr. Rahman is an associate professor at the Department of Plant Bio sciences, Iwate University, Japan and one of the founding member of GNOBB. The study reports a fascinating connection of cold response of Arabidopsis with the endosomal trafficking and GNOM a sec7 containing ARF-Guanine exchange factor. GNOM is required for both apical-basal pattern formation of early embryo and root formation. The GNOM mutant lines shows variable tolerance to short and long term cold stress with different mutations in the protein. The team identified GNOM as an important modulator of cold stress response and demonstrate that cold resistant plants can be engineered by manipulating this single protein. With this exciting finding they are provisioning identification and characterization of all the proteins that are trafficked by GNOM will help in engineering the plants with good yield under severe cold stress. Both Dr. Rahman and Arif Ashraf are former students of Department of Biochemistry and Molecular Biology, University of Dhaka. GNOBB wishes them best in their search for cold tolerance mechanism.
