Pollen Tube Growth and Fruit Set in Apple

The effect of supplementary hand pollination on fruit set and pollen tube growth in apple

Self-incompatibility in the Iranian Almond Cultivar ‘Mamaei’ Using Pollen Tube Growth, Fruit Set and PCR Technique

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

An extracellular transglutaminase is required for apple pollen tube growth.

An extracellular form of the calcium-dependent protein-cross-linking enzyme TGase (transglutaminase) was demonstrated to be involved in the apical growth of Malus domestica pollen tube. Apple pollen TGase and its substrates were co-localized within aggregates on the pollen tube surface, as determined by indirect immunofluorescence staining and the in situ cross-linking of fluorescently labelled...

Ions and Pollen Tube Growth

Ions play a crucial role in the control of pollen tube growth. In this review we focus on four that seem especially important: calcium (Ca2+), protons (H+), potassium (K+), and chloride (Cl–). Ca2+ in the extracellular medium is essential for growth; it forms a steep intracellular tip-focused gradient, and exhibits a prominent extracellular tip-directed Ca2+ influx. pH is also essential for gro...
