General Information

EC Number General Information Comment Organism
2.7.1.134 malfunction the epidermis structure of seed coat is irregularly formed in seeds of itpk2-1 mutant, resulting in the increased permeability of seed coat to tetrazolium salts. The cell wall shows a dramatic decrease in composition of suberin and cutin, which relate to the permeability of seed coat and the formation of which is accompanied with seed coat development. ITPK2 deficiency results in the distorted seed coat and crumpled columellas. Seed coat of itpk2-1 mutant presents high permeability to 2,3,5-triphenyltetrazolium and has less mucilage Arabidopsis thaliana
2.7.1.134 physiological function enzyme ITPK2 plays an essential role in seed coat development and lipid polyester barrier formation Arabidopsis thaliana
