Source Description
UniprotDEVELOPMENTAL STAGE: Expressed in the apical parts of the developing gynoecium. Detected throughout the youngest flower primordium. Later relocalizes towards the regions of the presumptive sepal anlagen and remains in sepal primordia until just after their emergence. Also observed on the abaxial side of the young floral meristem. Present in the newly arisen gynoecial primordium. Restricted to the apical parts of the carpels as the open-ended gynoecial cylinder elongates vertically. In the apical regions of the gynoecium, confined to a zone in the interphase between the style and the stigma and fades out later. Within the gynoecium, accumulates in ovule primordia, and, as the ovules developed, restricted to the epidermis of the developing funiculi, to the outer, but not the inner, integuments and to the tip of the nucellus. Also present in the cell layer of the septum that faces the ovary. In the embryo, detected in the cotyledon primordia during late globular to mid heart stage. In addition, transiently expressed in petal and stamen primordia and in the tapetum of the anthers. {ECO:0000269|PubMed:12361963}.

Source Description
TAIRA member of SHI gene family. Arabidopsis thaliana has ten members that encode proteins with a RING finger-like zinc finger motif. Despite being highly divergent in sequence, many of the SHI-related genes are partially redundant in function and synergistically promote gynoecium, stamen and leaf development in Arabidopsis. STY1/STY2 double mutants showed defective style, stigma as well as serrated leaves. Binds to the promoter of YUC4 and YUC8 (binding site ACTCTAC)
UniProtTranscription activator that binds DNA on 5'-ACTCTAC-3' and promotes auxin homeostasis-regulating gene expression (e.g. YUC genes), as well as genes affecting stamen development, cell expansion and timing of flowering. Synergistically with other SHI-related proteins, regulates gynoecium, stamen and leaf development in a dose-dependent manner, controlling apical-basal patterning. Promotes style and stigma formation, and influences vascular development during gynoecium development. May also have a role in the formation and/or maintenance of the shoot apical meristem (SAM). {ECO:0000269|PubMed:12361963, ECO:0000269|PubMed:16740145, ECO:0000269|PubMed:16740146, ECO:0000269|PubMed:18811619, ECO:0000269|PubMed:20154152, ECO:0000269|PubMed:22318676}.

  3. Induction of the transcriptional activator DORNROSCHEN-LIKE (DRNL) activates the transcription of STY1 and other SHI/STY family members and that this activation is dependent on a functional GCC box.

UniProtDISRUPTION PHENOTYPE: Gynoecia with aberrant style morphology. The double mutant sty1-1 and sty2-1 has a reduction in the amount of stylar and stigmatic tissues and decreased proliferation of stylar xylem, as well as shorter siliques and rosette and cauline leaves with a higher degree of serration. Hypersensitive to 1-N-naphthylphtalamic acid (NPA), but restored by exogenous application of auxin. {ECO:0000269|PubMed:12361963, ECO:0000269|PubMed:16740145, ECO:0000269|PubMed:16740146, ECO:0000269|PubMed:18811619}.
