The Arabidopsis GPI-anchored protein COBL11 is necessary for regulating pollen tube integrity
Cell Reports, 2023 Summary: Pollen tube integrity is required for achieving double fertilization in angiosperms. The rapid alkalinization factor4/19-ANXUR1/2-Buddha’s paper seal 1/2 (RALF4/19-ANX1/2-BUPS1/2)-complex-mediated signaling pathway is critical to maintain pollen

Editorial: Regulation of Pollen Tube Growth [PDF]
, 2021 In angiosperms, the pollen tube is a simple system composed of the vegetative cell and the two sperm cells which, nevertheless, accomplishes a very important process, essential for the life of flowering plants on Earth, i.e., sexual reproduction.

ROS in the Male–Female Interactions During Pollination: Function and Regulation
Frontiers in Plant Science, 2020 The male–female interactions in pollination mediate pollen hydration and germination, pollen tube growth and fertilization. Reactive oxygen species (ROS) derived from both male and female tissues play regulatory roles for the communication between the ...

Pollen Germination and Tube Growth in Northern Highbush Blueberry are Inhibited by Extreme Heat
HortScience, 2023 The increasing intensity and frequency of extreme heat events threaten crop productivity globally. Certain phases of plant reproduction necessary for fertilization are highly sensitive to extreme heat, particularly during pollen development, germination,

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 ...

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,

Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]
, 1988 Effects of the phytotoxic compounds (AAL-toxins) isolated from cell-free culture filtrates of Alternaria alternata f.sp. lycopersici on in vitro pollen development were studied. AAL-toxins inhibited both germination and tube growth of pollen from several
