Pollen-pistil interaction in wheat
Acta Botanica Neerlandica, 1994General organization and ultrastructure of pistil transmitting tract (PTT) for pollen tube pathway in wheat (Triticum aestivum L.) and pollen tube growth were studied. The peculiar features of cell ultrastructure in different parts of the PTT were shown and point to heterogeneous pollen tube pathway.

Species Specificity in Pollen-Pistil Interactions
Annual Review of Genetics, 2004▪ Abstract For pollination to succeed, pollen must carry sperm through a variety of different floral tissues to access the ovules within the pistil. The pistil provides everything the pollen requires for success in this endeavor including distinct guidance cues and essential nutrients that allow the pollen tube to traverse enormous distances along a ...

Pollen–pistil interaction is unique to flowering plants. This is one of the critical postpollination phases that determine reproductive success. Following conspecific compatible pollination, pollen grains germinate on the receptive stigma and the resulting pollen tubes grow through the tissues of the stigma and style and enter the ovules where they ...

Membrane proteins involved in pollen-pistil interactions
Biochimie, 1999Self-incompatibility (SI) is a widespread mechanism in angiosperms which prevents self-fertilization. This mechanism relies on cell-cell interactions between pollen and pistil. Among the different SI systems that have been reported, two have been particularly investigated: the gametophytic system of Solanaceae and the sporophytic system of Brassicaceae.

The need, site, and eventually, mode of pollen-pistil interaction; in other words—the extent of compatibility—is the focus of my work. In the case of the angiosperm flower, stigma, style and ovary are the sites where interaction occurs. In binucleate species, no active interaction seems to occur at the stigma site.

Mentor effects in pistil-mediated pollen–pollen interactions
1997Recent results on the use of mentor pollen to overcome self- or interspecific incompatibility are reviewed. The different treatments used to prepared de mentor pollen and their efficiency are analysed, especially on tree, fruit, and vegetable crops.

Pollination is a process that is vital for the survival not only of flowering plants, but also for mankind. Yet human efforts to manipulate the reproduction of crop plants have been largely empirical. Today, research into plant reproduction is not given high priority.

Planta, 2021
In flowering plants, pollen germination on the stigma and pollen tube growth in pistil tissues are critical for sexual plant reproduction, which are involved in the interactions between pollen/pollen tube and pistil tissues. GPI-anchored proteins (GPI-APs) are located on the external surface of the plasma membrane and function in various processes of ...

The molecular and genetic basis of pollen–pistil interactions
New Phytologist, 2001SummaryOver the past decade or so, there has been significant progress towards elucidating the molecular events occurring during pollination in flowering plants. This process involves a series of complex cellular interactions that culminates in the fusion between male and female gametes. The process also regulates crucial events such as pollen adhesion,

Pollen-pistil interaction in maize: effects on genetic variation of pollen traits
Theoretical and Applied Genetics, 1995Various factors (pollen diameter, in vitro germination and tube length, in vivo growth rate in selfed and nonselfed styles) which could possibly contribute to the competitive ability of pollen were investigated on 30 Zea mays L. inbred lines. The only factor with which pollen diameter was positively correlated was in vitro pollen-tube growth.
