Source Description
UniprotDEVELOPMENTAL STAGE: During anther development, accumulates in anther primordia during archesporial cell specification and later present in a horseshoe pattern associated with the lateral and adaxial portion of primordia, prior to the emergence of distinct locules. Expressed throughout sporogenic tissue and surrounding cells layers in adaxial and adaxial locules. Localized to the tapetum and middle layers, gradually fading postmeiosis with degeneration of these cell layers. {ECO:0000269|PubMed:20805327}.
UniprotTISSUE SPECIFICITY: Mostly expressed in stems, inflorescence apex and flowers, and, to a lower extent, in seedlings, leaves and siliques. {ECO:0000269|PubMed:20805327}.
Functional Description ? help Back to Top
Source Description
UniProtTogether with TGA10, basic leucine-zipper transcription factor required for anther development, probably via the activation of SPL expression in anthers and via the regulation of genes with functions in early and middle tapetal development (PubMed:20805327). Required for signaling responses to pathogen-associated molecular patterns (PAMPs) such as flg22 that involves chloroplastic reactive oxygen species (ROS) production and subsequent expression of H(2)O(2)-responsive genes (PubMed:27717447). {ECO:0000269|PubMed:20805327, ECO:0000269|PubMed:27717447}.

  1. Mutations in TGA9 and TGA10 lead to male sterility and differential defects in abaxial and adaxial anther lobe development similar to roxy1 roxy2 mutants. [TGA9]
