About the Plant Biotechnology Lab

Plant Biotechnology Lab is located in the Vegetable and Fruit Improvement Center at Texas A&M University. It consists of two labs, plant transformation lab and molecular breeding lab. Plant transformation lab has growth chambers, incubators, autoclaves, laminar flow hoods, microscopes and a thermo controlled culture room. Molecular breeding lab is equipped to be able to conduct cloning genes, DNA and RNA preparation and purification, PCR and electrophoresis. Major equipments include thermal cyclers, gel imaging systems, spectrophotometers, centrifuges, freezers, incubators and shakers.

Research

Our research interests are in molecular breeding. The goal is to develop fruit and vegetable varieties having optimized health beneficial bioactive compounds for consumers using marker assisted selection. Genetic transformation approach is also taken to enhance the level of carotenoids in muskmelon and limonoids in citrus. We try to understand molecular genetic basis and regulation mechanism of phytochemial biosynthesis, such as carotenoids and flavonoids. We have been identifying and characterizing key enzymes involved in carotenoid and flavonoid biosynthetic pathway in carrots and onions.

Current Projects

. Development of molecular markers linked to restorer-of-fertility (ms) gene in onion
. Elucidating phytochemical biosynthesis mechanism in carrot by biochemical and molecular approaches.
. Determining feasibility of grapefruit transformation to elevate limonoid glucoside and reduce bitter compound by genetic engineering approach.
. Genetic transformation to enhance the beta-carotene level in melon fruits.
