Pistil factors controlling pollination.
The successful establishment of angiosperms on land is in part determined by their floral design. Because plants cannotmove to find the idealmate, they have developed agreat variety of flowers to provide different mechanisms of pollen release, pollen transfer, and deposition of the pollen from the male to the female sexual organs, the anther and the pistil, respectively. Pollination ensures the...
متن کاملPollen-pistil interactions in compatible pollination.
Plant sexual reproduction depends on highly specific interactions between pollen and pistil, the male gametophyte and the female reproductive organ, respectively (1, 2). The pistil is composed of three major structural parts: the stigma, the style, and the ovary. The stigma has a pollen-receptive surface and several underlying secretory cell layers. The style connects the stigma to the basally ...
متن کاملMorphological and Proteomic Analysis Reveal the Role of Pistil under Pollination in Liriodendron chinense (Hemsl.) Sarg
Pollination is an important physiological process during which interaction between pollen and pistil occurs. This interaction could determine whether or not fertilization will occur and hence the ratio of plant seed setting. Liriodendron chinense (Hemsl.) Sarg. (L. chinense) exhibits a distinct phenomenon where seed setting ratio is not more than 10% in natural environment. To explore the origi...
متن کاملEthylene synthesis and auxin augmentation in pistil tissues are important for egg cell differentiation after pollination in maize.
The role of ethylene and auxin in stigma-to-ovule signalling was investigated in maize (Zea mays L.). Maturation of the egg cells in an ear was stimulated before actual fertilization by the application of fresh pollen grains or quartz sand to fully receptive stigmas. Ethylene emission by maize ears increased in response to those treatments. Silks and ovaries were involved in ethylene synthesis ...
متن کاملFactors controlling Arctic denitrification
Denitrification of the Arctic winter stratosphere has been calculated using a 3-D micro-tion is assumed to occur through the sedimentation of low number concentrations of large nitric acid trihydrate (NAT) particles, as observed extensively in 1999/2000. We 5 examine whether the meteorological conditions that allowed NAT particles to grow to the very large sizes observed in 1999/2000 also occur...
