Abstract excerpt

Wild type seed coats of Arabidopsis thaliana are brown due to the accumulation of proanthocyanidin pigments (PAs). The pigmentation requires activation of phenylpropanoid biosynthesis genes and mutations in some of these genes cause a yellow appearance of seeds, termed transparent testa (tt) phenotype. The TT1 gene encodes a WIP-type zinc finger protein and is expressed in the seed coat endothelium where most of...
