The rice gene Os03g0790600 was reported as PLASTOCHRON3 (PLA3)/GOLIATH (GO) in 2009[1].
Contents
Annotated Information
Function
- PLASTOCHRON3 (PLA3)/ GOLIATH (GO) regulates various developmental processes including the rate of leaf initiation (the plastochron). PLA3/GO encodes a glutamate carboxypeptidase, which is thought to catabolize small acidic peptides and produce small signaling molecules.
Mutation
- Two recessive mutations, pla3-1 and pla3-2, caused pleiotropic phenotypes including a shortened plastochron (Figures 1a). Mature embryos of pla3/go mutants were significantly larger than those of wild type (Figure 1b–e). All of the embryonic organs were enlarged, including scutellum, plumule, radicle and epiblast (Figure 1d,e). The patterning and positioning of the organs were not disturbed. In pla3-3 (go-1) and pla3-4 (go-2), two radicles were occasionally formed (Figure 1h). In addition, four foliage leaves were differentiated in pla3 embryos in contrast to three leaves in wild-type embryos (Figure 1f,g). The overproduction of leaves could be due to a reduced dormancy, because pla3 seeds frequently showed vivipary (Figure 1i–k).
