Abstract

A novel WRKY-like transcription factor was isolated from a screen for weakly expressed mRNAs in ovules in the self-incompatible wild potato species Solanum chacoense Bitt. This protein, named ScWRKY1, consisted of 525 amino acids and can be classified as a WRKY group-I member, having two WRKY domains. It is expressed at low levels in stems, roots, and petals, and expressed at much higher levels in leaves. Interestingly, although barely detectable in developing seeds, it is strongly and transiently expressed in fertilized ovules bearing late torpedo-staged embryos, suggesting a specific role during embryogenesis.
