Tolerance Genes: Identifying Key Functional Genes for Salt and Drought Tolerance

This research focuses on identifying key functional genes related to salt and drought tolerance in extremophiles. A genomics-scale approach is needed to study the genetic databases, genomes sequences, and transcriptomes to understand the mechanisms behind tolerance. The KAUST Center for Salt Tolerant Plant Genomics aims to develop innovative solutions for crop improvement and enhance food security while protecting the environment. The goal is to improve crop yields, develop new crops, and extend cropland to marginal soils.
