A pistil may consist of one carpel (with its ovary, style and stigma); or it may comprise several carpels joined together to form a single ovary, the whole unit called a pistil. The gynoecium may present as one or more uni-carpellate pistils or as one multi-carpellate pistil.
The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae , the cells of which are receptive to pollen.
Sarracenia trap insects using pitchers with nectar and slippery footing around the lip The anatomy of S. purpurea. Sarracenia (/ ˌ s ær ə ˈ s iː n i ə / or / ˌ s ær ə ˈ s ɛ n i ə /) is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers.
The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
The first experiment compares the features of the pistil and the stigma of rmd-1 mutant (rice plant without a functional RMD) and the wild-type rice plant (with a functional RMD). The anther and pistil were shorter in the rmd-1 mutants than the wild-type. This experiment showed that RMD is critical for pollen development.
Based on molecular data it was shown that the genus Agrobacterium is nested in Rhizobium and the Agrobacterium species transferred to the genus Rhizobium (resulting in the following comp. nov.: Rhizobium radiobacter (formerly known as A. tumefaciens), R. rhizogenes, R. rubi, R. undicola and R. vitis) [102] Given the plant pathogenic nature of ...

The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae. It is derived from the fusion of both male and female parts ( stamens and pistil ) into a single organ. [ 1 ]
