Arabidopsis thaliana | CYP704B1 is highly coexpressed with CYP703A2, a cytochrome P450 involved in exine production | additional information |
General Information | Comment | Organism |
---|---|---|
physiological function | mutations in CYP704B1 result in impaired pollen walls that lack a normal exine layer and exhibit a characteristic striped surface, termed zebra phenotyp. Mutations in three genes, CYP704B1, CYP703A2, and another exine gene, MALE STERILITY2 result in pollen with remarkably similar zebra phenotypes, distinct from those of other known exine mutants. The double and triple mutant combinations do not result in the appearance of novel phenotypes or enhancement of single mutant phenotypes | Arabidopsis thaliana |
