Overview

Hormone analysis and transcriptomics show Trichagalma acutissimae induces galls in oak, suggesting hormonal roles.

Key Points

  • The study reveals that Trichagalma acutissimae larvae synthesize auxins and cytokinins, contributing to gall formation.
  • Preliminary data show that gall tissues exhibit higher levels of auxins, with IAA biosynthesis genes downregulated in the galls.
  • Transcriptome analysis indicates active biosynthesis suppression of jasmonic acid, reinforcing the nutritional hypothesis of gall formation.
  • Integration of hormonal dynamics and transcriptomic data broadens understanding of plant-insect interactions in gall induction.
