AP2-like ethylene-responsive transcription factor ANT

Gene

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Transcription activator that recognizes and binds to the DNA consensus sequence 5'-CAC[AG]N[AT]TNCCNANG-3'. Required for the initiation and growth of ovules integumenta, and for the development of female gametophyte. Plays a critical role in the development of gynoecium marginal tissues (e.g. stigma, style and septa), and in the fusion of carpels and of medial ridges leading to ovule primordia. Also involved in organs initiation and development, including floral organs. Maintains the meristematic competence of cells and consequently sustains expression of cell cycle regulators during organogenesis, thus controlling the final size of each organ by controlling their cell number. Regulates INO autoinduction and expression pattern. As ANT promotes petal cell identity and mediates down-regulation of AG in flower whorl 2, it functions as a class A homeotic gene.12 Publications

Expressioni

Tissue specificityi

Mostly expressed in developing flowers. Also present in mature flowers, siliques and seedlings, but not in mature roots, leaves and stems. Expressed in ovules and in vegetative and floral primordia.3 Publications

Developmental stagei

Expressed in floral primordia, in STM-negative region, then in sepal primordia. As sepal develops, progressively confined to a basal core before disappearing. Present in stamen primordia, then confined to a central region as they become stalked and develop locules. Later reduced to procambial cells as stamen mature. From petal primordia, expressed on the lateral edges of developing petals and finally confined to petal epidermis before disappearing. Present in carpel primordia, then in inner side of carpels especially in the placenta. Strong levels in ovules primordia and young ovules, then localized in integuments initiation zone before being confined to inner integument cells that will differentiate into the endothelium. Expressed in the distal half of the funiculus throughout ovule development and later extends into the chalaza. After fertilization, expression shift to the embryo. First on the apical part at the globular stage, then in cotyledons primordia, and later in cotyledons during the torpedo stage. As cotyledons grow out, expression becomes limited to a plane separating adaxial and abaxial parts. Excluded from the embryonic central region (ECR). In seedlings, found in leaf primordia then in central and lateral actively developing regions of extending leaves.3 Publications

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.
