The Effects of PPAL-1 in Arabidopsis Gamete Development

Prenylation is a type of post-translational modification in which 15- or 20-carbon lipid added to the carboxyl (C) terminus protein. Arabidopsis thaliana contains PROTEIN PRENYLTRANSFERASE ALPHA SUBUNIT-LIKE (PPAL) gene, encodes protein with homology ?-subunits three known prenylation enzymes, PFT, PGGT, and Rab-GGT. We previously identified two mutations PPAL, one ppal-1, T-DNA insertion fourth intron. have observed that self-fertilizing heterozygous ppal-1 plants produce progeny homozygous underrepresented. This project attempts ascertain possible affects gametophyte growth development might cause this underrepresented population.
