CAP peptides artificially induce insect-gall-like growth in different plant species.

ABSTRACT: The formation of galls by gall-inducing insects on their host plants demonstrates the concept of 'extended phenotype', referring to traits expressed in a host organism manipulated by a parasite. Phytohormones, amino acids, and proteins have been suggested as compound types involved in gall formation, and a few specific molecules have been proposed as candidate effector molecules; however, no specific gall-inducing effector molecules have been identified. Hence, in this study, we identified the cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1 proteins (CAP) peptide from horned gall aphid Schlechtendalia chinensis transcripts through in silico screening and the Arabidopsis-based gall-forming assay, a bioassay system for analysing the molecular mechanisms of gall format
