About Valeriy

During the last three years Valeriy has been working in the University of Illinois for Dr. Hans Bohnert. His research activity in this period is an “research in the area of plant genomics”. During this period he was involved in several genomics projects: the “Rice stress genomics project” - sequencing and submission to the Gene Bank the Rice ESTs obtained from the salt stressed rice plants and design and printing ~15000 unigenes rice microarray; “Cyanophora paradoxa project” (in collaboration with Austrian colleagues) - the small (2500 features), ESTs based, array for the alga Cyanophora paradoxa; “Corn Root project” – three normalized and bar-coded cDNA libraries for the water stressed and control corn roots, and one SAGE library for well watered corn root were constructed,  sequenced, and submitted to Gene Bank. This SAGE library is a biggest plant SAGE library submitted to the Gene Bank by a single laboratory.
