Female gametophyte-controlled pollen tube guidance
Biochemical Society Transactions, 2010During the evolution of flowering plants, their sperm cells have lost mobility and are transported from the stigma to the female gametophyte via the pollen tube to achieve double fertilization. Pollen tube growth and guidance is largely governed by the maternal sporophytic tissues of the stigma, style and ovule.

Pollen Germination and Pollen-Tube Growth
1987Publisher Summary Pollen germination and pollen-tube growth events when viewed either in culture or in the style are considered as biochemically, physiologically, and structurally complex. The various processes involved are each independent in some measure, but still all are interactive—namely, the successful attainment of the delivery of two male ...

Culture of Pollen Tubes for Chromosomal Analysis at the Pollen Tube Division
Stain Technology, 1953It is possible to grow pollen tubes routinely for cytological analysis of nuclei at the pollen tube division. Pollen has been grown successfully after temperature, pressure, gas, moisture, and radiation treatments. The technic for growing Tradescantia pollen is described, but any method is satisfactory which ensures that: (a) the pollen is kept dry ...

Cotton Transformation via Pollen Tube Pathway
2012Although many gene transfer methods have been employed for successfully obtaining transgenic cotton, the major constraint in cotton improvement is the limitation of genotype because the majority of transgenic methods require plant regeneration from a single transformed cell which is limited by cotton tissue culture.
