|a In order to understand the functioning of apical meristems in Arabidopsis more clearly, a new mutant, mgoun3 (mgo3), affected in the structural organization and the functional regulation of both shoot and root meristems has been isolated. mgo3 plants display perturbations in leaf morphogenesis, in the spatial and the temporal formation of primordia, and frequent fasciation of the inflorescence stem. Cellular analysis showed that both cellular organization and cell identity patterning are impaired in the mutant meristems. The MGO3 gene has been isolated by positional cloning. The protein deduced from the cDNA sequence contains TetratricoPeptide Repeats (TPR) and Leucine-Rich Repeats (LRR), two motifs that are thought to act in protein-protein interactions. This gene appears to be unique in the Arabidopsis genome. Although the MGO3 protein presents TPR as in the Arabidopsis proteins HOBBIT and SPINDLY, the MGO3 motifs are more similar to those present in LGN-related proteins, which are regulators for some of the asymmetric cell divisions in animal development. These features suggest a key role for MGO3 in meristematic cell divisions and would be of interest for the comparison between plant and animal development
