Pollen Tube Growth and Self-Compatibility in Almond [PDF]
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.

Significance Plant sexual reproduction is required for seed and fruit production and is highly sensitive to elevated temperatures, suggesting that climate change may have profound agricultural impacts through inhibition of this process.

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.

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

Reproductive abnormalities in interspecific crosses involving Gossypium hirsutum and Gossypium arboreum [PDF]
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
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

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]
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.

Arabidopsis pollen tube integrity and sperm release are regulated by RALF-mediated signaling
Timing a switch in tissue integrity In plants, sperm cells travel through the pollen tube as it grows toward the ovule. Successful fertilization depends on the pollen tube rupturing to release the sperm cells (see the Perspective by Stegmann and Zipfel).

Incidence and post-pollination mechanisms of nonrandom mating in Arabidopsis thaliana [PDF]
Compatible pollinations from many differenttaxa display nonrandom mating. Here we describe a systemfor examining questions of nonrandom mating in Arabidopsisthaliana.
