Function
Rice PAP2 encodes MADS34, a grass-specific SEPALLATA(SEP) subfamily MADS domain protein.PAP2 functions as a positive regulator of SM identity[1].PAP2 also functions as a suppressor of the extra elongation of glumes[2].In addtion,PAP2 activated in the meristem at phase transition and function in specifying IM identity in rice[3].
Mutation
- Figure 1 shows the Phenotype of the wild type and pap2-1 mutant in panicle development.the arrangement of lateral organs, such as rachis branches and spikelets, was disordered and the panicle became irregularly denser, in sharp contrast to the well-defi ned phyllotaxy of the wild-type panicle ( Fig. 1B–D ).A signifi cant increase in the number of primary rachis branches per panicle was observed in pap2-1 , indicating that the IM activity was maintained longer in pap2-1 than in the wild-type ( Fig. 1F ).In the wild-type panicle, 31.0 % of lateral organs produced in the primary rachis branches grow as secondary rachis branches, whereas 70.8 % become secondary branches in pap2-1 ( Fig. 1G ).
- Figure 2 shows the Phenotype of the wild and pap2-1 mutant in spikelet development.(A–C) shows the Spikelets in the wild-type (A) and pap2-1 (B, C).(D–F)shows SEM analysis of the spikelet of wild-type (D) and pap2-1 (E, F).(G and H) shows the number of rudimentary glumes (G) and
sterile lemmas (H) in the wild-type and pap2-1 .Approximately 60 % of the spikelets in a pap2-1 panicle exhibited elongated rudimentary glumes, and 40 % of them developed an ectopic filamentous organ.Approximately 13 % of the sterile lemmas elongated to about half the size of the lemma, 65 % grew to a similar size and 23 % grew longer.

Expression
PAP2 expression starts the earliest among the five SEP genes, and a low but signifi cant level of PAP2 mRNA was detected in the infl orescence meristem, in branch meristems immediately after the transition, and in glume primordia, consistent with its role in the early development of spikelet formation.
Evolution
OsMADS34 is a member of the MADS-box gene family that regulates many aspects of plant growth and development. PAP2/OsMADS34 is a type II MADS-box gene (there are > 44 known type II MADS-box genes), a member of the SEPALLATA ( SEP ) subfamily，PAP2/OsMADS34 belong to the LOFSEP subgroup( Fig. 3）。
