General Information

EC Number General Information Comment Organism
1.14.14.80 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
1.14.15.3 malfunction mutations in CYP703A2 or CYP704B1 genes result in pollen with remarkably similar zebra phenotypes (impaired pollen walls that lack a normal exine layer and exhibit a characteristic striped surface). Double and triple mutant combinations do not result in the appearance of novel phenotypes or enhancement of single mutant phenotypes Arabidopsis thaliana
1.14.15.3 physiological function CYP703A2 and CYP704B1 together with the fatty acyl reductase MALE STERILITY2 are required to provide an indispensable subset of fatty acid-derived components within the sporopollenin biosynthesis framework Arabidopsis thaliana
