POLLEN TUBE GROWTH IN MANDARIN

Revista Fitotecnia Mexicana, 2022
Pollen tube growth was studied in cvs. Monica, Reyna, Dancy, and Satsuma mandarin (Citrus reticulata unshiu Marc). Pollen tubes were stained with lacmoid and observed with a white light microscope. Lacmoid stained the callose brilliant blue. Pollen grains deposited on the stigma varied from 367 to 4170 among the four cultivars.

Effect of boron toxicity on pollen tube cell wall architecture and the relationship of cell wall components of Castanea mollissima Blume

Frontiers in Plant Science, 2022
Boron (B) is essential to plant development. However, excessive B is toxic to plants. This research was performed to evaluate the effects of B toxicity on cell wall architecture of Chinese chestnut (Castanea mollissima Blume) pollen tubes with emphasis ...

Structural basis for recognition of RALF peptides by LRX proteins during pollen tube growth

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Plant reproduction relies on proper pollen tube growth to reach the female gametes. This process is highly regulated by a family of secreted signaling peptides that are recognized by cell-wall monitoring proteins to enable plant ...

Overexpression of the Tomato Pollen Receptor Kinase LePRK1 Rewires Pollen Tube Growth to a Blebbing Mode [PDF]

, 2014
The tubular growth of a pollen tube cell is crucial for the sexual reproduction of flowering plants. LePRK1 is a pollen-specific and plasma membrane–localized receptor-like kinase from tomato (Solanum lycopersicum). LePRK1 interacts with another receptor,

LLG2/3 Are Co-receptors in BUPS/ANX-RALF Signaling to Regulate Arabidopsis Pollen Tube Integrity

Current Biology, 2019
SUMMARY In angiosperms, two sperm cells are transported and delivered by the pollen tube to the ovule to achieve double fertilization. Extensive communication takes place between the pollen tube and the female tissues until the sperm cell cargo is ...

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,

Phosphatidic acid counteracts S-RNase signaling in pollen by stabilizing the actin cytoskeleton [PDF]

, 2018
S-RNase is the female determinant of self-incompatibility (SI) in pear (Pyrus bretschneideri). After translocation to the pollen tube, S-RNase degrades rRNA and induces pollen tube death in an S-haplotype-specific manner. In this study, we found that the

LORELEI-LIKE GPI-ANCHORED PROTEINS 2/3 regulate pollen tube growth as chaperones and coreceptors for ANXUR/BUPS receptor kinases in Arabidopsis.

Molecular Plant, 2019
Pollen tube growth is crucial for successful fertilization. In Arabidopsis thaliana, the ANXUR (ANX)/BUPS receptor kinase complex controls and maintains pollen tube growth in response to autocrine RAPID ALKALINIZATION FACTOR4/19 (RALF4/19) signaling ...

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.

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 ...
