Adhesion and guidance in compatible pollination.

The mechanisms of compatible pollination are less studied than those of incompatible pollination and yet most of the angiosperms show self-compatibility. From the release of pollen from anthers to the penetration of the micropyle by the pollen tube tip, there are numerous steps where the interaction between pollen and the pistil can be regulated. Recent studies have documented some diverse ways...

Pollen-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 ...

Pollination and Fruit Set: Pollination Requirement

Considerable infonnation has been developed on floral induction and the flowering process in Citrus in the papers which precede this one. Flower induction is a prerequisite to fruit production, so it is very important to have a clear understanding ofthe process. However, simply producing large numbers offlowers does not necessarily guarantee a subsequent large crop of fruit to harvest when they...

Cell-to-substratum adhesion and guidance of axonal elongation.

The behavior of axonal growth cones on surfaces with patterned variations in substratum was observed. Cells from sensory ganglia of 8-day-old chicken embryos were cultured on plastic petri dishes, plastic tissue culture dishes, and polyornithine-coated tissue culture dishes, all of which contained gridlike patterns of palladium (Pd) deposition. The results indicated that growth cones elongated ...
