Introduction
Cotton growth and productivity is severely reduced by various
types of stress. Therefore, adequate techniques and management
is required to increase its productivity. Cotton leaf curl
virus (CLCuV) has emerged as a serious threat to cotton plants
by causing leaf curl disease and affecting cotton production by
making up to 80% loss in North India and Pakistan (Varma
and Malathi, 2003; Mansoor et al., 2003; Sattar et al., 2013).
Cotton leaf curl virus belongs to begomovirus group, family,
Geminivirideae. CLCuV possesses DNA-A and a satellite molecule
known as b DNA. The b DNA has only one gene
(bC1gene). It acts as the pathogenicity, a suppressor of post
transcriptional gene silencing (Hammond et al., 2001) and
