Cadmium stress disrupts the endomembrane organelles and endocytosis during Picea wilsonii pollen germination and tube growth. [PDF]
As one of the most severe pollutants, cadmium has been reported to be harmful to plant cells, but the effects of cadmium on gymnosperm pollen germination and tube growth and the mechanism of this involvement are still unclear.

Genome-Wide Analysis of Cyclic Nucleotide-Gated Channel Genes Related to Pollen Development in Rice
In the angiosperm, pollen germinates and rapidly expands the pollen tube toward the ovule. This process is important for plant double fertilization and seed setting.

Spermidine Modulates Pollen Tube Growth by Affecting the Factors Involved in Pollen Tube Elongation
Putrescine, spermine, and spermidine are among the most significant polyamines for plant growth and development, including pollen tube elongation. Although the effects of putrescine and spermine are well-known on tube elongation, little is known about the impact of spermidine.

Research Progress on Calcium Ion in Gametophytic Self-Incompatibility
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 ...

Gibberellin Regulates Pollen Viability and Pollen Tube Growth in Rice [PDF]
AbstractGibberellins (GAs) play many biological roles in higher plants. We collected and performed genetic analysis on rice (Oryza sativa) GA-related mutants, including GA-deficient and GA-insensitive mutants. Genetic analysis of the mutants revealed that rice GA-deficient mutations are not transmitted as Mendelian traits to the next generation ...
