  abstract = {{B}ackground: {T}he {A}frican rice {O}ryza glaberrima was domesticated from its wild relative {O}ryza barthii about 3000 years ago. {D}uring the domestication process, panicle complexity changed from a panicle with low complexity in {O}. barthii, to a highly branched panicle carrying more seeds in {O}. glaberrima. {T}o understand the basis of this differential panicle development between the two species, we conducted morphological and molecular analyses of early panicle development. {R}esults: {U}sing {X}-ray tomography, we analyzed the morphological basis of early developmental stages of panicle development. {W}e uncovered evidence for a wider rachis meristem in {O}. glaberrima than in {O}. barthii. {A}t the molecular level, spatial and temporal expression profiles of orthologs of {O}. sativa genes related to meristem activity and meristem fate control were obtained using in situ hybridization and q{RT}-{PCR}. {D}espite highly conserved spatial expression patterns between {O}. glaberrima and {O}. barthii, differences in the expression levels of these early acting genes were detected. {C}onclusion: {T}he higher complexity of the {O}. glaberrima panicle compared to that of its wild relative {O}. barthii is associated with a wider rachis meristem and a modification of expression of branching-related genes. {O}ur study indicates that the expression of genes in the mi{R}156/mi{R}529/{SPL} and {TAW}1 pathways, along with that of their target genes, is altered from the unbranched stage of development. {T}his suggests that differences in panicle complexity between the two {A}frican rice species result from early alterations to gene expression during reproductive development.},
