Analysis of the roles of PERPETUAL FLOWERING 1 direct target genes in perennial flowering and their divergence in sister annual species

Perennial plants live for many years and flower every year while annual plants undergo senescence after flowering. The transcription factor PERPETUAL FLOWERING 1 (PEP1) has been shown to be involved in specifying seasonal flowering patterns within the perennial life cycle of Arabis alpina. In my project I want to analyze the function of PEP1 direct targets and determine whether these vary between perennial A. alpina and annual sister species. Direct targets of PEP1 will be identified by comparing ChIPseq and RNAseq data sets. Candidates will be further characterized by expression analysis and functional studies using transgenic plants or reverse genetic approaches. Understanding the distinction between perennial and annual life style can be a first step in engineering perennial crops from annuals to provide a regular yield combined with reduced expenses.
