Abscisic acid 8'-hydroxylase 2

Gene

CYP707A2

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

Functioni

Expressioni

Tissue specificityi

Mainly expressed in dry seeds. Lower expression in rosette leaves, flowers, siliques and stems. Not expressed in roots. Expressed in both endosperm and vascular tissues of embryo during the seed development and in cortex and endodermis in germinating embryo.2 Publications

Developmental stagei

Up-regulated from late-maturation to mature dry seed. Up-regulated immediately after seed imbibition, reaching a maximum at 6 hours and decreasing therafter.2 Publications

Inductioni

By abscisic acid, dehydration and rehydration. Expression regulated by phytochrome B.2 Publications

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.
