Current Research

My interests include the molecular genetic analysis of plant development, focusing on male reproduction and the events occurring during pollen and anther development. We have used mutants that are defective at various stages of pollen development to study genes critical to these pathways. These stages range from meiotic aberrations, to tapetal abnormalities and the degeneration of immature pollen, through to dehiscence mutants that produce functional pollen that does not get released.

One of the most important anther tissues is the tapetum, which is essential for synchronizing development of the maternal anther tissues and the developing gametophytes. We are interested in the regulatory activities of the tapetum and the roles it plays in pollen development, and have been investigating the regulatory networks of two tapetal transcription factors, ABORTED MICROSPORE (AMS) and MALESTERILITY1 (MS1). We have identified a number of AMS regulatory targets and interacting factors, which are preferentially expressed in male reproductive tissues and have functionally linked these to pollen formation. We have also characterised MS1 and shown that it has homology to the PHD-finger class of transcription regulators, is expressed in the anther tapetum but has highly regulated expression. MS1 alters transcription in the anther and they have identified a large number of MS1-target genes, many of which are involved in pollen wall synthesis. MS1 is also involved in the control of tapetal secretion and programmed cell death (PCD). We are extending this work into the study of orthologues of these gene and interacting factors in crop species.

Another major focus is anther dehiscence and we are using an indehiscent mutant, ms35, to elucidate anther endothecial development and secondary wall thickening. We have shown that this is due to a mutation in the MYB26 gene, which is critical for specifying secondary thickening in the anther. We have over-expressed AtMYB26 and observed ectopic secondary thickening, and shown that MYB26 regulates a number of
