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

open access: yes, 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,

Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]

open access: yes, 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

Gibberellin Regulates Pollen Viability and Pollen Tube Growth in Rice [PDF]

open access: yesThe Plant Cell, 2007
AbstractGibberellins (GAs) play many biological roles in higher plants. We collected and performed genetic analysis on rice (Oryza sativa) GA-related mutants, including GA-deficient and GA-insensitive mutants. Genetic analysis of the mutants revealed that rice GA-deficient mutations are not transmitted as Mendelian traits to the next generation ...

Organization and Regulation of the Actin Cytoskeleton in the Pollen Tube

open access: yesFrontiers in Plant Science, 2015
Proper organization of the actin cytoskeleton is crucial for pollen tube growth. However, the precise mechanisms by which the actin cytoskeleton regulates pollen tube growth remain to be further elucidated.

Research Progress on Calcium Ion in Gametophytic Self-Incompatibility

open access: yesJournal of Horticultural Research, 2022
Calcium ions are involved in plant self-incompatibility response as important signaling substances in cells. In the sporophytic self-incompatibility response, Ca2+ enters the stigma papilla cells and plays a key role in inhibiting incompatible pollen ...

Apical vesicles: Social networking at the pollen tube tip

open access: yesReproduction and Breeding, 2022
Pollen tube growth is asymmetric and highly focused at the tip. It is regarded as an ideal model cell system in plants to study polar cell growth and cell polarity.

Flower Biology of Two Diospyros Species Neighborly Live at Csc Area: Do Pollen Viability and Tube Growth Rate Shire Endemic Distribution [PDF]

open access: yes, 2008
Aims of study were to compare flower structure, pollen viability and pollen tube growth rate of two Diospyros species neighborly live in Cibinong Science Centre (CSC) park, Diospyros blancoi and D.

Exocytosis-coordinated mechanisms for tip growth underlie pollen tube growth guidance

open access: yesNature Communications, 2017
Many tip-growing cells are capable of responding to guidance cues, during which cells precisely steer their growth toward the source of guidance signals.

Pollen germination and pollen tube growth in ZP maize lines [PDF]

open access: yesGenetika, 2014
The study was conducted on the in vitro pollen germination at 26?, 28?, 32? and 35?C for 24h of male parental lines, pollen tube growth in vivo in cross pollination of female and male parental lines that make couples in four hybrids: ZP 504 su (? ZPPL 51 ? ? ZPPL 67); ZP 677 (? ZPPL 17 ? ? ZPPL 201); ZP 704 (? ZPPL 109 ? ?

Roles for NO and ROS signalling in pollen germination and pollen-tube elongation in Cupressus arizonica

open access: yesBiologia 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.
