Research interest:

Sexual plant reproduction in higher plants involves pollination, involving specific interactions between pollen and pistil. A key mechanism to prevent inbreeding is self-incompatibility (SI), which is a controlled by a single, multi-allelic S-locus. Incompatible (“self”) pollen is rejected and compatible (“non-self”) pollen is allowed to fertilize the plant.

Prof Franklin-Tong’s lab is investigated the signaling cascades, targets and mechanisms regulating pollen tube tip growth inhibition induced by SI in Papaver. The “self” interaction triggers a Ca2+-dependent signaling network, resulting in incompatible pollen tube tip growth being inhibited and programmed cell death being induced. The long-term goal is to establish how the different components integrate and interact in what has turned out to be a complex signaling network.
