Function
The molecular basis of plastochron regulation remains to be uncovered. plastochron 1 (pla1) is the first mutant that drastically alters plastochron, in which leaf primordia are formed approximately twofold faster than in the wild type. Concomitantly, leaves of pla1 become short, suggesting that PLA1 regulates organ size. The PLA1 gene encodes a cytochrome P450 family protein (CYP78A11). An Arabidopsis homolog of PLA1, KLUH, was shown to regulate organ size. Subsequently, the PLA2 and PLA3 genes, loss-of-function mutants of which exhibit similar phenotypes to that of pla1, were identified. These encode an RNA-binding protein and glutamate carboxypeptidase, respectively. Interestingly, PLA1 and PLA2 are expressed in young leaf primordia, but not in shoot meristems. Therefore, based on analyses of the developmental processes of leaves, the primary functions of PLA1 and PLA2 are suppression of precocious leaf maturation, and that some non-cell autonomous signals move from leaf primordial through shoot meristems to suppress the formation of a new leaf primordium. Thus, PLA1 and PLA2 are key genes for elucidating leaf development.
PLA1 and PLA2 show several phenotypes likely related to phytohormones, such as small leaf size, dwarfism and enlarged SAM. In addition, the phytohormone (CK, abscisic acid and IAA) contents of pla mutants differed from those of the wild type. These mutant phenotypes suggest that PLA genes have some relationship with phytohormones.
Expression
PLA1 and PLA2 gene expression is associated with GA signaling. Thus, the research team examined the effect of GA on PLA1 and PLA2 gene expression. Ten-day-old seedlings were treated with 10 lM GA3 and PLA gene expression was monitored for 24 h by real-time PCR. PLA1 and PLA2 expression increased as early as 3 h after treatment, and a high level of expression was maintained for 24 h. To investigate the longterm effect of GA, wild-type seeds were inoculated and grown for 8 days on culture media containing 10 lM GA3. PLA1 and PLA2 expression was maintained at a high level for 8 days. Next, we examined the effect of uniconazole, a GA biosynthesis inhibitor. Uniconazole treatment markedly suppressed PLA1 and PLA2 gene expression. Therefore, GA regulates the expressions of both PLA1 and PLA2.
Evolution
According to the recommendation of the Cyto-chrome P450 Gene Nomenclature Committee, the PLA1 protein was designated as CYP78A11 (GenBank accession no. AB096259). The CYP78A class comprises 11 members including rice CYP78A11. Rice CYP78A11 forms a cluster with maize CYP78A1 (GenBank accession no. L23209) and Arabidopsis CYP78A7 (GenBank accession no. AC016893) (Fig. 2c). CYP78A11 exhibits the highest similarity to the CYP78A1 of maize (71% amino acid identity), and strong similarity to Arabidopsis CYP78A7 (61% identity) and Pinus radiata CYP78A4 (59% identity; GenBank accession no. AF049067). Genes in the CYP78A class belong to the group A cytochrome P450 in plants. They are phylogenetically more closely related to each other than to non-group A cytochrome P450s and seem to be involved in plant-specific reactions.
