Transcription profiling of Arabidopsis thaliana LFY mutant plants transformed with either Arabidopsis LFY or Leanworthia crassa LFY to investigate evolutionary divergence of LFY function

The aim of this experiment is to test the ability of the ortholog of Arabidopsis LFY gene from Leanworthia crassa (Lcr) to complement an Arabidopsis LFY mutant. Plants used are homozygous lfy6 mutants (EMS alleles) in Ler background which are transformed or not (for the lfy6 mutant) by genomic clones for Arabidopsis LFY (AthLFY) or Leanworthia crassa LFY (LcrLFY). Flowering was synchronized by growing plants in SD then shifting them to LD. 2 time points samples (wild type Ler) were taken at the end of the SD period as a reference for genes induced by shifting to LD, irrespective of the status at the LFY locus.
