Arabidopsis thaliana wild-type vs. cotyledon-less laterne (= pid enp homozygous) mutant

Transcriptional profiling of cotyledon transcriptomics at the seedling stage (6 d) by comparison of wild-type vs. cotyledon-less laterne (= pid enp) homozygous mutant. The goal was to determine the transcriptomic profile of a cotyledon. The experiment took advantage of the endogenously caused lack of cotyledons instead of dissecting these organs, which would cause wound-induced expression.This was achieved by comparing seedlings of the Arabidopsis thaliana pid enp double mutant, which is incapable to generate cotyledons. This is caused by the loss of apical cell polarisation of the auxin efflux carrier PIN1 in epidermal cells during embryogenesis. Two-color experiments with four independent biological replicates no1-4. The experiments were repeated with reversed colors as technical replicates.
