In plants this choice occurs at many stages during reproduction, but pollen-pistil interactions play a particularly important role in avoiding inbreeding and hybridisation with other species. Interestingly, the mechanisms involved in avoidance of selfing and interspecific hybridisation may wor...
News & Views13 Feb 2020 Nature Plants Volume: 6, P: 53-54 An SI-independent regulator The stigma has tightly regulated recognition mechanisms at several levels to prevent unwanted pollen from achieving fertilization. Knowledge about barriers controlling interspecific incompatibility is scarce. New ev...
Plants in their natural environment are involved in multiple interspecific biotic interactions, for example with animals that pollinate flowers and/or feed on plant tissue26,27. By feeding on plants, herbivores induce strong selection on defense mechanisms in plants that may differ depending on the f...
About 75 per cent of plants on earth are angiosperms and over 80 per cent of angiosperms are pollinated by insects. Entomophily or insect pollination is considered tobemore efficient andreliable than other mechanisms of pollen transfer as it confers advantages such as reduced requirement of pollen...
Various types of pollination occur in seed plants. As to plant-to-plant pollen transfer, two types existself-pollinationandcross-pollination. Classification has also been made according to agents of pollination. Having a sufficient understanding of these pollination mechanisms is important in crop agric...
In the Tropics, issues regarding pollination are especially important because the natural pollination mechanisms of many plants (crops and others) are not known (Kevan, 1984a, 1995; Mbaya and Kevan, 1995; Roubik, 1995). Expanded and continued evaluation and development of management practices for ...
As plants have evolved, their mechanisms of reproduction have adapted to continually ensure the highest possibilities of successful reproduction as environments changed. For plants that grow in aquatic environments or moist biomes like rainforests, there is abundant water, and plants have motile male ...
Pollen grains in flowering plants cannot independently transfer, thus they require agents to aid in their movement. Therefore, flowers adopt different mechanisms to attract or facilitate the pollination process. Examples include brightly colored flowers that attract birds and bees, which in turn act as...
and as a result interspecific pollen transfer is ubiquitous in communities worldwide12. Interspecific pollen transfer has certainly been seen as one of the mechanisms underlying competition among plants for pollinators13,14, notwithstanding it can also reflect facilitation7,15,16,17,18. Ultimately, th...
flower's style and into the individual's own stigma. This mode of self-pollination is a new addition to the broad range of genetic and morphological mechanisms that have evolved in flowering plants (angiosperms)1, and may be common in species growing in shady, windless and insect-poor ...
