Calreticulin is required for calcium homeostasis and proper pollen tube tip growth in Petunia
Planta, 2017 Main conclusionCalreticulin is involved in stabilization of the tip-focused Ca2+gradient and the actin cytoskeleton arrangement and function that is required for several key processes drivingPetuniapollen tube tip growth.

In Vitro Studies on Pollen Viability, Pollen Germination and Pollen Tube Growth of Hornstedtia Conoidea Ridl. – a Philippine Endemic Ginger Species [PDF]
, 2018 Zingiberaceous plants are predominantly propagated through underground rhizomes and seeds. In this study, the viability of pollen, rate of pollen germination and length of pollen tube of the Philippine endemic Hornstedtia conoidea were examined.

NADPH Oxidase-Dependent Superoxide Production in Plant Reproductive Tissues [PDF]
, 2016 In the life cycle of a flowering plant, the male gametophyte (pollen grain) produced in the anther reaches the stigmatic surface and initiates the pollen–pistil interaction, an important step in plant reproduction, which ultimately leads to the delivery ...

Pollen Tube Growth and Fruit Set in Apple
, 2017 . Pollination is an essential prerequisite for the production of many fruit and seed crops, including apple. In apple, successful fertilization requires pollen transfer to the stigma, pollen germination, and successful pollen tube growth resulting in ...

Messenger RNas : their utilization and degradation during pollen germination and tube growth
Acta Societatis Botanicorum Poloniae, 2014 During pollen germination and tube growth at least 230 new proteins are synthesized, as determined by 35S-methionime labeling and two dimensional gel electrophoretic analysis of the labeled proteins.

Glycosidases in pear pollen tube development [PDF]
, 2017 During the in vitro germination of pear pollen, several hydrolases were released into the medium. They were apparently eluted from the pollen grain, since the activity was the same when germination was inhibited. These enzymes, once released, had no role
