Floral homeotic protein APETALA 1-1

Gene

1AP1

Organism
Brassica oleracea var. italica (Broccoli)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Transcription factor that promotes early floral meristem identity in synergy with LEAFY. Displays a redundant function with CAULIFLOWER in the up-regulation of LEAFY. Required subsequently for the transition of an inflorescence meristem into a floral meristem, and for the normal development of sepals and petals in flowers. Regulates positively B class homeotic proteins (By similarity).By similarity

Expressioni

Tissue specificityi

Expressed in some of the meristems of arrest-stage broccoli heads.1 Publication

Developmental stagei

First observed in young floral meristem before organs initiation. Accumulates strongly in the sepals of the early stage bud. In more mature buds, expressed on the adaxial side of the sepals, in the petal primordia, and transiently in young stamen primordia.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
