Pollen biology and hormesis: Pollen germination and pollen tube elongation
Science of The Total Environment, 2021 This paper evaluated the occurrence of hormetic dose responses in pollen reported over the past eight decades. Hormetic doses responses were induced by a wide range of chemical and physical agents in 34 plant species for pollen germination and pollen tube growth/elongation.

WD40-domain protein GORI is an integrative scaffold that is required for pollen tube growth in rice
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
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 ...

Biologia Plantarum, 2015 Roles for nitric oxide (NO) and reactive oxygen species (ROS) during pollen-tube growth have been well established in angiosperms, but there remains lack of information regarding their potential signalling roles in pollen tubes in gymnosperms.

Reproductive abnormalities in interspecific crosses involving Gossypium hirsutum and Gossypium arboreum [PDF]
Electronic Journal of Plant Breeding, 2010 A successful cross fertilization involving two different species implies that a chain of reproductive process takes placeunhampered after pollination. The coordination and interaction between genes or gene complexes in the pollen parent andmatching gene ...

Arabidopsis LIM proteins PLIM2a and PLIM2b regulate actin configuration during pollen tube growth
Biologia Plantarum, 2013 The pollen tube grows rapidly, exclusively at its tip, to deliver its sperm for fertilization. The polarized tip growth of pollen tubes is dependent on the highly dynamic actin cytoskeleton. Plant LIM proteins (named after initials of containing proteins

BMC Plant Biology, 2019 Background The transmitting tissue of the style is the pathway for pollen tube growth to the ovules and has components that function in recognizing and discriminating appropriate pollen genotypes. In Nicotiana tabacum, the class III pistil extensin-like (

Actin Bundles in The Pollen Tube [PDF]
International Journal of Molecular Sciences, 2018 The angiosperm pollen tube delivers two sperm cells into the embryo sac through a unique growth strategy, named tip growth, to accomplish fertilization. A great deal of experiments have demonstrated that actin bundles play a pivotal role in pollen tube tip growth.

Transport Logistics in Pollen Tubes [PDF]
Molecular Plant, 2013 Cellular organelles move within the cellular volume and the effect of the resulting drag forces on the liquid causes bulk movement in the cytosol. The movement of both organelles and cytosol leads to an overall motion pattern called cytoplasmic streaming or cyclosis.
