Fig. 2From: Differences in meristem size and expression of branching genes are associated with variation in panicle phenotype in wild and domesticated African riceHistological description of early differentiation of African rice panicle and corresponding stages for expression analysis. O. barthii: a–g O. glaberrima: h–n. Developmental stages selected for in situ hybridization and qRT-PCR analyses are indicated in lower panel. Stage 1: unbranched stage with elongation of rachis meristem and formation of primary branch meristems; stage 2: early branching stage with at the end the initiation of spikelet meristem differentiation; stage 3: late branching stage with elongated secondary branch and complete spikelet meristem differentiation; stage 4: floret organ differentiation/development.
