Cotton production is widely effected by Cotton Leaf Curl Virus (CLCuV) in world posing serious losses to cotton yield. The CRT genes from CLCuV resistant G. arboreum and CLCuV susceptible G. hirsutum were cloned and sequenced to know the differences of protein composition in both species. Molecular techniques were used to isolate full length putative biotic stress resistance genes from G. arboreum besides the analysis of identified novel genes in model plant tobacco (Nicotiana tabacum) for resistance to cotton leaf curl disease complex. It was found that transgenic plants over expressing Hydroperoxidelyase (HPL) genes exhibited higher enzyme activity than wild type. In addition the genome sequence information was used for the purpose of gene isolation. Even for the enhanced expression of Calreticulin (CRT), AOS and HPL in G. hirsutum, it still showed susceptibility against CLCuV suggesting alternative genes and pathways involved for the expression of resistance.
