Species specificity in pollen-pistil interactions.
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 complex path to the unfertilized ovule. Although the pis...
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 کاملPeptide signaling in pollen-pistil interactions.
Plant fertilization is achieved through the involvement of various pollen-pistil interactions. Self-/non-self-recognition in pollination is important to avoid inbreeding, and directional and sustainable control of pollen tube growth is critical for the pollen tube to deliver male germ cells. Recently, various secreted peptides (polypeptides) have been reported to be involved in cell-cell commun...
متن کاملIn Vitro Pollen Germination - A Review
Pollen is a unique plant tissue that potentially can be used and manipulated to the advantage of the geneticist, breeder, physiologist, or germplasm curator. Since pollen of most species is haploid and each cell is independent, pollen has the potential to provide a microbial-like system for evaluation, assay, and selection. Whatever the interest and use, the viability of the pollen is necessary...
متن کاملIn Vitro Germination of Avocado Pollen
Abstract. Avocado pollen was germinated in vitro without recourse to germination on the style. The technique employed involved inclusion of pollen grains in liquid medium of 15% sucrose and minerals and application of 1 or 2 drops on 1% agar plus 15% sucrose and minerals. No germination was obtained on agar plus sucrose without placement of pollen in liquid first. Of the cultivars tested, 'Etti...
