DESCRIPTION:Meiosis is the specialised cell division that gives rise to th
 e haploid cells required for gamete formation and sexual reproduction. The
  factors that induce cells to undergo meiosis vary greatly between (and wi
 thin) eukaryotes and a meiotic trigger has yet to be defined in plants. He
 re we propose to use a forward genetic screen to identify sterile mutants 
 in Arabidopsis that fail to enter meiosis at the appropriate time and plac
 e during development. Fluorescent markers that selectively highlight meiot
 icytes or the surrounding cells are being generated to better characterise
  the developmental events surrounding meiosis. These will be used in combi
 nation with a meiotic indicator (callose accumulation) to screen for mutan
 ts with disrupted sporogenesis. By selecting mutants that exhibit normal e
 arly anther (male) and ovule (female) development but fail to complete mei
 osis\, we aim to indentify genes that are required for meiotic commitment 
 in Arabidopsis.
