Overview

Identifies ABC transporter Sl-ABCB5 in tomato to enhance insect resistance by secreting acylsugars.

Key Points

  • To investigate the role of the ABC transporter Sl-ABCB5 in acylsugar secretion from tomato trichomes and its impact on insect resistance.
  • Utilized CRISPR-Cas9 to create Sl-ABCB5 knockout mutants in cultivated tomato.
  • Conducted in vitro transport assays with membrane vesicles and protoplasts to assess acylsugar transport capacity.
  • Applied virus-induced gene silencing on ABCB5 orthologs in wild tomato and black nightshade to explore functional conservation.
  • Knockout of Sl-ABCB5 mutants showed a significant decrease in acylsugar content in trichomes.
  • Increased susceptibility to western flower thrips was observed in Sl-ABCB5 knockout mutants.
  • Functional conservation of ABCB5 was demonstrated across Solanaceae species.
