pistil
Britannica Concise Encyclopedia | Date: 2007
Female reproductive part of a flower. Centrally located, the pistil typically has a swollen base called the ovary, which contains the potential seeds (ovules). The stalk (style) arises from the ovary and has a pollen-receptive tip, the stigma, which is variously shaped and often sticky. There may be a single pistil, as in the lily, or several to many pistils, as in the buttercup. Each pistil is constructed of one to many rolled leaflike structures, or carpels. Differences in the composition and form of the pistil are useful in classifying flowering plants. stamen.

ARC1 is an E3 ubiquitin ligase and promotes the ubiquitination of proteins during the rejection of self-incompatible Brassica pollen
Plant Cell; 4/1/2003; Stone, Sophia L; Anderson, Erin M; Mullen, Robert T; Goring, Daphne R; 787 words
; ARC1 is a novel U-box protein required in the Brassica pistil for the rejection of self-incompatible pollen; it functions downstream of the S receptor kinase (SRK). Here, we show that ARC1 has E3 ubiquitin ligase activity and contains several motifs that influence its subcellular localization. ARC1

Pistil Factors Controlling Pollination
Plant Cell; 1/1/2004; Sanchez, Ana Maria; Bosch, Maurice; Bots, Marc; Nieuwland, Jeroen; Et al; 787 words
; INTRODUCTION The successful establishment of angiosperme on land is in part determined bytheirfloral design. Because plants cannot move to find the ideal mate, they have developed a great variety of flowers to provide different mechanisms of pollen release, pollen transfer, and deposition of the

Structural and transcriptional analysis of the self-incompatibility locus of almond: Identification of a pollen-expressed F-box gene with haplotype-specific polymorphism
Plant Cell; 3/1/2003; Ushijima, Koichiro; Sassa, Hidenori; Dandekar, Abhaya M; Gradziel, Thomas M; Et al; 787 words
; Gametophytic self-incompatibility in Rosaceae, Solanaceae, and Scrophulariaceae is controlled by the S locus, which consists of an S-RNase gene and an unidentified "pollen S" gene. An ~70-kb segment of the S locus of the rosaceous species almond, the S haplotype-specific region containing the

A Selfish Gene Governing Pollen-Pistil Compatibility Confers Reproductive Isolation Between Maize Relatives
Genetics; 1/1/2006; Kermicle, Jerry L; 787 words
; ABSTRACT Some populations of maize's closest relatives, the annual teosintes of Mexico, are unreceptive to maize pollen. When present in the pistil (silk and ovary) a number of maize genes discriminate against or exclude pollen not carrying the same allele. An analogous gene Tcb1-s was found in

The Molecular and Genetic Bases of S-RNase-Based Self-Incompatibility
Plant Cell; 1/1/2004; Kao, Teh-hui; Tsukamoto, Tatsuya; 787 words
; INTRODUCTION The majority of flowering plants produce perfect flowers that contain both the male and female reproductive organs in close proximity; consequently, they would have a strong tendency to self-fertilize if there were no mechanisms to prevent them from doing so. Because inbreeding can
