Understanding leaf development is important since leaf shape and positioning influence photosynthesis. The maize development mutant rld-5409 is characterized by upwardly rolled leaves resulting from errors in leaf polarity determination. The rld-5409 gene has been mapped to the distal end of the long arm of chromosome 4. RNA-Seq analysis of laser-captured leaf primordia from mutant and wild-type plants has identified a candidate gene within the mapping interval that is differentially regulated in the rld-5409 mutants. Arabidopsis thaliana has been used as a model plant system to understand development. The homolog of the rld-5409 candidate gene has been identified from The Arabidopsis Information Resource. Arabidopsis seeds with an insertion-mutation in this homolog are being grown to compare the Arabidopsis and maize mutants. Several mutant phenotypes potentially involved in leaf development have been observed. Molecular genetic analyses will indicate if any of these phenotypes co-segregate with insertions in the Arabidopsis homolog.
