Description | Pleiotropic phenotypes in embryogenesis, early vegetative and reproductive phases: In early vegetative, meristem produces threadlike leaves with aberrant phyllotaxis. However, in late vegetative phase, plants relatively normal except for leaf phenotypes, such as threadlike leaves with normal dorsoventrality or partial loss of leaf domains. Marginal domain may be deleted from leaf. Less severe phenotypes have bi- or trifurcated leaf blade. In some leaves, midrib is separated from other tissues in middle of abaxial leaf blade. Wide variation of leaf phenotypes caused by lesion of one or two leaf domains or by nonsynchronous growth of the three domains. With SEM, the central domain is seen to develop earlier than the other two domains. Synchronous initiation and growth of the three domains are severely disrupted. Aberrant proper induction of leaf domains in shoot apical meristem is thought to be caused by sho2 gene. |
