Most of our studies, including molecular studies have implicated morphological traits like hairs on leaf and leaf thickness (sometimes the close packing of cells in the epidermis of leaves) in tolerance to jassids. Are there definitive findings , at the biochemical level (not the usual high sugar content or presence of gossypol etc, which have been accounted for) where the insects are deterred from attacking/ the plant shows resilience to attack. Any transcriptome studies in cotton up on infestation.
