Insect eggs represent a threat for the plant as hatching larvae rapidly start with their feeding activity. Using a whole-genome microarray, we studied the expression profile of Arabidopsis (Arabidopsis thaliana) leaves after oviposition by two pierid butterflies. For Pieris brassicae, the deposition of egg batches changed the expression of hundreds of genes over a period of 3 d after oviposition. The transcript signature was similar to that observed during a hypersensitive response or in lesion- ...[more]
Project description:Compare gene expression in the resting leaves of Arabidopsis thaliana WT with the mutants fou2 and tpc1-2. To analyse the contribution of the fou2 and tpc1-2 mutations in Arabidopsis thaliana to gene expression, transcript levels in the resting leaves of Arabidopsis were measured using 4 weeks-old plants grown in control conditions (long day).
