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.
