(n.) The seed-bearing organ of a flower. It consists of an ovary, containing the ovules or rudimentary seeds, and a stigma, which is commonly raised on an elongated portion called a style. When composed of one carpel a pistil is simple; when composed of several, it is compound. See Illust. of Flower, and Ovary.
Example Sentences:
(1) Raised levels of atmospheric water cause a variety of responses in self-pollen, ranging from tube growth through the pistil to the ovary, to tubes inhibited at the stigmatic surface, accompanied by the formation of callose.

(10) After pollination, the transcript levels of the pistil-specific extensin-like genes change relative to levels in unpollinated pistils.
(11) Compatible and incompatible pollen tubes growing on detached Lilium longiflorum pistils which had been prelabeled with myoinositol-U-(14)C take up a portion of the label and utilize it for biosynthesis of tube wall substance.
(12) The S2- and S3-alleles encode pistil-specific proteins of 30 kDa and 31 kDa, respectively, which were previously identified based on cosegregation with their respective alleles in genetic crosses.

(14) The possible roles of the extensin-like proteins in pistils are discussed.
(15) A glycoprotein serologically related to the PR-2,N,O class is a (1,3)-beta-glucanase and is present in pistils.
(16) Here we report the characterization of a gene encoding another pistil ribonuclease of P. inflata, RNase X2.
(17) Double staining with sirofluor allows location of nuclei within pollen tubes grown in vitro, and when used after pollination enables the viewer to discriminate between nuclei within the pollen tube vs. nuclei of the pistil tissue.
(18) In the case of pistils, a pattern of labeling in ovary, style, and stigma is obtained which indicates that products of myoinositol metabolism are utilized in the biosynthesis of exudate (secretion product) of the stigma and style as well as for components of pistil cell walls.
(19) RNA gel blot hybridizations demonstrated the organ-specific expression of the extensin-like genes and their temporal regulation during pistil development.
(20) We have sought to identify pistil-specific genes that can be used as molecular markers to study pistil development.
