Expression -- Description ? help Back to Top
Source Description
UniprotTISSUE SPECIFICITY: Expressed at high levels in roots, low level in leaf sheath, but not in leaf blade. Predominantly expressed in vascular tissues. {ECO:0000269|PubMed:14704272}.
UniprotTISSUE SPECIFICITY: Ubiquitous. Strongly expressed in mature pollen. {ECO:0000269|PubMed:27896439}.

Source Description
UniProtTranscription factor probably involved in vascular development and shoot tissue organization. Binds to the DNA sequence 5'-CCGAGTGTGCCCCTGG-3' present in the promoter region Box II of the phloem-specific rice tungro bacilliform virus (RTBV) promoter. May regulate tissue-specific expression of the RTBV promoter and virus replication. {ECO:0000269|PubMed:14704272}.
UniProtTranscrition factor that may participate with bZIP34 in the gametophytic control of pollen development. {ECO:0000269|PubMed:27896439}.
