The process of the landing of pollen on the stigma, pollen tube growth and entry of germ cells in the ovule are the events covered in the germination of pollen grains. Let us study each event in detail.
Pollen, the male gametophyte of higher plants, is a biological system playing a central role in sexual plant reproduction (Cresti et al., 1992). The understanding of the mechanisms controlling the various aspects of pollen tube development has a direct relevance to...
Pollen germination and tube growth are processes fundamental for reproduction of flowering plants. Germinating and mature maize pollens were compared via gel-based proteomic tools (Zhu et al., 2007 ).
Explain cross-pollination and the ways in which it takes place. Describe the process that leads to the development of a seed. Define double fertilization. In angiosperms, pollination is defined as the placement or transfer of pollen from the anther to the stigma of the same flower or another flower.
Many aspects of Angiosperm pollen germination and tube growth are discussed including mechanisms of dehydration and rehydration, in vitro germination, pollen coat compounds, the dynamic involvement of cytoskeletal elements (actin, microtubules), calcium ion fluxes, extracellular matrix elements (stylar arabinogalactan proteins), and control ...
Oct 1, 2023 · Pollen germination is a prerequisite for double fertilization of flowering plants. A comprehensive understanding of the structural and molecular basis of pollen germination holds great potential for crop yield improvement.
Jan 1, 2010 · Pollen grains transfer from a quiescent state to a germination program when they land on the stigma. Successful landing and adhesion is the essential first step to initiate an intimate mating dialogue between both male and female gametophytes.
