The proteins of T. licus licus are shown in green. Black spots indicate the APNs that have been reported as putative Cry toxin receptors. Red spots indicate the APNs which gene expression changed after Bt infection. Red squares indicate the APNs which silencing induced resistance of the insect to Cry1Ab. GenBank accession number is shown for each protein.
