Abstract

PLENA (PLE) is one of the best characterised plant organ identity genes. It encodes a MADS transcription factor with a key role in floral organ identity which is also required to terminate development in the centre of the flower. Many mutants are available including various degrees of loss-of-function, an ectopic expression of ple allele and non-allelic mutants which result in ectopic PLE expression. PLE has also been used to alter floral organ identity in transgenic plants. Despite this and in common with other plant MADS-box factors, almost nothing is known about the regulation of the PLE expression, its mode of action or is target genes. We propose to investigate the control of PLE expression concentrating on two identified intragenic regulatory elements. We will also extend our studies on the first putative plant MADS-factor TCF and initiate a search for the target genes of PLENA.
