Pollen Tube Growth and Self-Compatibility in Almond [PDF]
Plants, 2013 Although pollen tube growth has been an important criterion for self-compatibility evaluation in almond, there is not a clear-cut separation between positive and negative growth of pollen tubes in the different genotypes.

Pollen Germination and Pollen Tube Growth in Gymnosperms. [PDF]
Plants (Basel), 2021 Pollen germination and pollen tube growth are common to all seed plants, but these processes first developed in gymnosperms and still serve for their successful sexual reproduction. The main body of data on the reproductive physiology, however, was obtained on flowering plants, and one should be careful to extrapolate the discovered patterns to ...

Cell Wall Composition, Biosynthesis and Remodeling during Pollen Tube Growth
Plants, 2013 The pollen tube is a fast tip-growing cell carrying the two sperm cells to the ovule allowing the double fertilization process and seed setting. To succeed in this process, the spatial and temporal controls of pollen tube growth within the female organ ...

WD40-domain protein GORI is an integrative scaffold that is required for pollen tube growth in rice [PDF]
Plant Signaling & Behavior, 2023 The pollen tube plays a critical role in angiosperm plants by delivering sperm gametes for double fertilization. Although the molecular mechanisms underlying pollen tube germination and growth are crucial to crop plants, they are poorly understood. Here,

Possible molecular mechanisms of persistent pollen tube growth without de novo transcription [PDF]
Frontiers in Plant Science, 2022 The vegetative cell nucleus proceeds ahead of a pair of sperm cells located beneath the pollen tube tip during germination. The tip-localized vegetative nucleus had been considered to play a pivotal role in the control of directional pollen tube growth ...

Identification and functional analysis of arabinogalactan protein expressed in pear pollen tubes
Journal of Integrative Agriculture, 2023 Arabinogalactan proteins (AGPs) are widely distributed in the plant kingdom and play a vital role during the process of plant sexual reproduction. In this study, we performed a comprehensive identification of the PbrAGPs expressed in pear pollen and ...

Nitric oxide participates in cold-inhibited Camellia sinensis pollen germination and tube growth partly via cGMP in vitro. [PDF]
PLoS ONE, 2012 Nitric oxide (NO) plays essential roles in many biotic and abiotic stresses in plant development procedures, including pollen tube growth. Here, effects of NO on cold stress inhibited pollen germination and tube growth in Camellia sinensis were ...
