Reproductive abnormalities in interspecific crosses involving Gossypium hirsutum and Gossypium arboreum [PDF]
Electronic Journal of Plant Breeding, 2010 A successful cross fertilization involving two different species implies that a chain of reproductive process takes placeunhampered after pollination. The coordination and interaction between genes or gene complexes in the pollen parent andmatching gene ...

Quantification of Pollen Viability in Lantana camara By Digital Holographic Microscopy [PDF]
arXiv, 2022 Pollen grains represent the male gametes of seed plants and their viability is critical for efficient sexual reproduction in the plant life cycle. Pollen analysis is used in diverse research thematics to address a range of botanical, ecological and geological questions. More recently it has been recognized that pollen may also be a vector for transgene

Frustration-induced inherent instability and growth oscillations in pollen tubes [PDF]
, 2012 In a seed plant a pollen tube is a vessel that transports male gamete cells to an ovule to achieve fertilization. It consists of one elongated cell, which exhibits growth oscillations, until it bursts completing its function. Up till now, the mechanism behind the periodic character of the growth has not been fully understood.

Research Progress on Calcium Ion in Gametophytic Self-Incompatibility
Journal of Horticultural Research, 2022 Calcium ions are involved in plant self-incompatibility response as important signaling substances in cells. In the sporophytic self-incompatibility response, Ca2+ enters the stigma papilla cells and plays a key role in inhibiting incompatible pollen ...
