Source Description
UniprotDEVELOPMENTAL STAGE: First detected in the boundary region of the shoot apical meristem (SAM) and the surrounding sheath. Expressed at low levels in vegetative organs, mostly in the sheaths. In inflorescence tissues, observed in the branch meristem and spikelet meristem regions, as well as in their vasculature and surrounding sheath (PubMed:17144896). Accumulates in incipient rudimentary- and empty-glume primordia (PubMed:22003982). Highly abundant in young developing panicles, but becomes later present at low levels in developing panicles and seeds. Found primarily in the boundary region of glume primordia (PubMed:17144896). {ECO:0000269|PubMed:17144896, ECO:0000269|PubMed:22003982}.
UniprotTISSUE SPECIFICITY: Highly expressed in seedlings and developing panicles (PubMed:17144896, PubMed:20017947, PubMed:22003982). Mostly expressed in newly emerging spikelet meristems and, at low levels, in shoots, roots, panicles, mature spikelets and sheaths (PubMed:17144896). {ECO:0000269|PubMed:17144896, ECO:0000269|PubMed:20017947, ECO:0000269|PubMed:22003982}.
Functional Description ? help Back to Top
Source Description
UniProtProbable transcription factor (By similarity). Involved in spikelet transition (Probable). Together with IDS1, controls synergistically inflorescence architecture and floral meristem establishment via the regulation of spatio-temporal expression of B- and E-function floral organ identity genes in the lodicules and of spikelet meristem genes (PubMed:22003982). Prevents lemma and palea elongation as well as grain growth (PubMed:28066457). Regulates the transition from spikelet meristem to floral meristem, spikelet meristem determinancy and the floral organ development (PubMed:17144896). {ECO:0000250|UniProtKB:P47927, ECO:0000269|PubMed:17144896, ECO:0000269|PubMed:22003982, ECO:0000269|PubMed:28066457, ECO:0000305|PubMed:26631749}.
