the SEP subfamily of the MADS-box proteins. We suggest that PAP2 is one of the key regulators for spikelet meristem identity in rice. Results The panicle of the pap2-1 mutant produces more rachis branches A wild-type panicle contains several primary rachis branches (prb) that are produced by...
Genetic studies, using floral homeotic mutants, have led to the ABC model of flower development. This model proposes that the combinatorial action of three sets of genes, the A, B and C function genes, specify the four floral organs (sepals, petals, stam

MADS-box genes have a wide range of functions, in the formation of flowers, the control of flowering time and the control of vegetative development. The landmark ABC model of flower organ identity states that three classes of homeotic gene, most of which encode MADS-box proteins, function ...
