Pollen and Pollen Tube Proteomics
Germinated pollen grains form pollen tubes that accomplish rapid polarized growth within female gametophytic tissues in order to deliver the sperm cell to the ovule. This process is essential for successful plant fertilization in vivo. Pollen tubes are considered to be an ideal model system to study tip growth. A more comprehensive understanding of proteins involved in pollen development, germi...

متن کاملGibberellin regulates pollen viability and pollen tube growth in rice.
Gibberellins (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 following self-pollination of F1 heterozygous plants, alth...
متن کاملPollen-specific pectin methylesterase involved in pollen tube growth.
Pollen tube elongation in the pistil is a crucial step in the sexual reproduction of plants. Because the wall of the pollen tube tip is composed of a single layer of pectin and, unlike most other plant cell walls, does not contain cellulose or callose, pectin methylesterases (PMEs) likely play a central role in the pollen tube growth and determination of pollen tube morphology. Thus, the functi...
