Functional Description ? help Back to Top
Source	Description
TAIR	Encodes a protein similar to WRKY transcription factors that is expressed in the seed integument and endosperm. Mutants are defective in proanthocyanidin synthesis and seed mucilate deposition. Seeds are yellow colored. Seed size is also affected; seeds are reduced in size but only when the mutant allele is transmitted through the female parent.Loss of function allele corresponding to the DSL QTL are associated with a reduction in interploidy lethality.

Complexes containing R2R3 MYB and bHLH transcription factors regulate the expression of TTG2, which then regulates GL2 expression with complexes containing R2R3 MYB. [PMID: 17766401] the role of the sporophytically active TTG2 gene in interploidy crosses indicates that the developmental programming of the mother regulates the viability of interploidy hybrid offspring. [PMID: 19071961] GIGANTEA-miRNA172-WRKY44 may regulate drought escape and drought tolerance by affecting sugar signaling in Arabidopsis. [PMID: 24223111] Data show that TRANSPARENT TESTA GLABRA 2 (TTG2) is a specific activator of TRYPTICHON protein (TRY) by binding to W-boxes in a minimal promoter fragment of TRY. [PMID: 25304203]
