Abstract
We have identified a key target protein (p26) that is phosphorylated as a key step (the earliest identified S- specific event in incompatible pollen) in the SI signalling cascade. p26 is a functional inorganic pyrophosphatase, whose activity is inhibited upon phosphorylation. This gives a clear model for the function of p26 in SI to test. We aim to pursue several inter-related lines of investigation. These are (i) Identification and characterisation of the CDPK that phosphorylates p26; (ii) Control of p26 activity by phosphorylation, and (iii) to test the model that regulation of the p26 activity is an important element in the inhibition of pollen tube growth during the SI reaction.
