       Dr. Balasubramanian was involved in establishment of Rice Transformation Facility at TNAU in 1996 with financial support from the Rockefeller Foundation New York. The Department of Biotechnology, New Delhi (DBT) with its funding assigned to him the work on cloning antifungal genes from Trichoderma spp. for use against Rhizoctonia solani, the invincible soil-borne plant pathogen. He worked in evolving several transgenic lines of elite rice cultivars of Tamil Nadu expressing resistance to sheath blight and bacterial blight by pyramiding genes encoding a chitinase, a thaumatin-like protein and Xa21. He built two Transgenic Greenhouse Facilities at TNAU with funding from the Govt. of Tamil Nadu and DBT. His transgenic lines are awaiting clearance from DBT for field trials.
       He was specialized in transgenic plant technology and molecular plant pathology and trained at University of California, Davis, John Innes Centre, UK and the Scripps Research Institute, La Jolla, USA.
