Radial leaves of the maize mutant ragged seedling2 retain dorsiventral anatomy.

Abstract excerpt

ragged seedling2 (rgd2) is a novel, recessive mutation affecting lateral organ development in maize. The mutant phenotype of homozygous rgd2-R leaves is variable. Mild leaf phenotypes have a reduced midrib and may be moderately narrow and furcated; severe Rgd2-R(-) leaves are filamentous or even radial. Despite their radial morphology, severe Rgd2-R(-) mutant leaves develop distinct adaxial and abaxial anatomical...
