| Type: | Family | Name: | Pistil-specific extensin-like protein |
| Description: | Extensins are plant cell-wall proteins; they can account for up to 20% of the dry weight of the cell wall. They are highly-glycosylated, possiblyreflecting their interactions with cell-wall carbohydrates. Amongst their functions is cell wall strengthening in response to mechanical stress (e.g.,during attack by pests, plant-bending in the wind, etc.). By contrast with extensin genes, pistil-specific extensin-like genes arenot induced under stress conditions. Gene expression is organ-specific and temporally regulated during pistil development. After pollination, transcript levels of pistil-specific extensin-like genes change relative to levels in unpollinated pistils []. The protein sequence is characterisedby multiple tandem ser-pro-pro-pro-pro pentapeptide repeats. | Short Name: | Pistil_extensin |
