RT   "STIG1 controls exudate secretion in the pistil of petunia and tobacco.";
RL   Plant Physiol. 138:153-160(2005).
CC   -!- FUNCTION: Involved in the temporal regulation of the exudate secretion
CC       onto the stigma. {ECO:0000269|PubMed:15821148}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:15821148}.
CC   -!- TISSUE SPECIFICITY: Expressed exclusively in the stigmatic secretory
CC       zone. {ECO:0000269|PubMed:8039494}.
CC   -!- DEVELOPMENTAL STAGE: Expressed early during pistil development.
CC       {ECO:0000269|PubMed:8039494}.
CC   -!- PTM: Glycosylated. {ECO:0000305|PubMed:15821148}.
CC   -!- DISRUPTION PHENOTYPE: No visible phenotype. Increased exudate
CC       production by the mature stigmas, but no effects on pollen tube
CC       germination, pollen tube growth or seed set.
CC       {ECO:0000269|PubMed:15821148}.
CC   -!- SIMILARITY: Belongs to the STIG1 family. {ECO:0000305}.
