Description | Many variable white stripes and margin patterns on leaves (compare cm1); conditions chloroplast defects that are cytoplasmically inherited. Many variable white stripes in seedlings and later leaves, boldest at the margins and base and at the edges of sheaths; expression varies with background from near-white seedlings that usually die (Oh51A) to distinctly striped (Mo17) to spiderly leaves (K55) to grainy with few white stripes (inbred line). Reference allele is mutable when activated, reverts to normal green (Ij1-Rev). Recessive allele conditions chloroplast defects that are maternally inherited. Plastid-encoded proteins and nuclear-encoded thylakoid-associated proteins absent but 33kD protein of the oxygen-evolving complex and ferredoxin:NADP oxidoreductase are accumulated at reduced levels. Plastid DNA content normal. Additional or missing plastid-encoded transcripts; possibly due to alterations in transcriptional or post-transcriptional processes. Alterations persist in maternal-exception progeny. Origin of the name is from "Iodent", the variety in which the mutant was found (Jenkins 1924), combined with "japonica", as previously applied to j1 (which see). 4th intron has rare 5' splice site sequence TTG/GCAA. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible. |
