E-MTAB-1777 - Transcription profiling by array of Arabidopsis Col-0 plants and myc2myc3myc4 triple mutant plants to study the transcription target of MYC2/MYC3/MYC4 and their role in controlloing jasmonate-related defense responses
Released on 27 August 2013, last updated on 2 May 2014
Arabidopsis thaliana plants fend off insect attack by constitutive and inducible production of toxic metabolites such as glucosinolates (GS). A triple mutant lacking MYC2, MYC3, and MYC4, three basic helix-loop-helix transcription factors that are known to additively control jasmonate-related defense responses, is highly susceptible to insect herbivory. In this study, we performed a whole-genome microarray analysis on three-week-old plants and compared wild-type (Col-0) and myc2myc3myc4 plants in control conditions (no treatment). Myc234 was shown to have a highly reduced expression of GS biosynthesis genes.
