FIGURE 1.

Leaf phenotype and cotton leaf curl virus (CLCuD) virus accumulation after CLCuD infection of upland cotton plants. (A) CLCuD accumulation in CK and CLCuD-inoculated cotton plants were estimated from total genomic DNA by qRT-PCR at 20 dpi. Values were normalized using the cotton histone gene (AF024716) as an internal reference. Error bars represent standard errors of three biological replicates and asterisk indicates the significant difference based on the Student’s t-test (P < 0.05). (B) Leaf phenotype after CLCuD infection at 60 dpi of the cotton plants.
