The pollen receptor kinase LePRK2 mediates growth-promoting signals and positively regulates pollen germination and tube growth [PDF]
In flowering plants, the process of pollen germination and tube growth is required for successful fertilization. A pollen receptor kinase from tomato (Solanum lycopersicum), LePRK2, has been implicated in signaling during pollen germination and tube ...

Kanamycin resistance during in vitro development of pollen from transgenic tomato plants [PDF]
Effects of kanamycin on pollen germination and tube growth of pollen from non-transformed plants and from transgenic tomato plants containing a chimaeric kanamycin resistance gene were determined. Germination of pollen was not affected by the addition of

Identification and functional analysis of arabinogalactan protein expressed in pear pollen tubes
Arabinogalactan proteins (AGPs) are widely distributed in the plant kingdom and play a vital role during the process of plant sexual reproduction. In this study, we performed a comprehensive identification of the PbrAGPs expressed in pear pollen and ...

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.

Regularized Stokeslet rings - an efficient method for axisymmetric Stokes flow, with application to the growing pollen tube [PDF]
The method of regularized Stokeslets, based on the divergence-free exact solution to the equations of highly viscous flow due to a spatially-smoothed concentrated force, is widely employed in biological fluid mechanics. Many problems of interest are axisymmetric, motivating the study of the azimuthally-integrated form of the Stokeslet which physically ...

The Arabidopsis mutant feronia disrupts the female gametophytic control of pollen tube reception [PDF]
Reproduction in angiosperms depends on communication processes of the male gametophyte (pollen) with the female floral organs (pistil, transmitting tissue) and the female gametophyte (embryo sac).

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

Abstract Small mountain lakes are natural archives for understanding long‐term natural and anthropogenic impact on the environment. This study focused on long‐term (last ca. 13 000 years) vegetation changes and sedimentary processes in the catchment area of Lake Planina pri jezeru (1430 m a.s.l.) by using mineralogical, geochemical and palynological ...

The juxtamembrane and carboxy-terminal domains of Arabidopsis PRK2 are critical for ROP-induced growth in pollen tubes. [PDF]
Polarized growth of pollen tubes is a critical step for successful reproduction in angiosperms and is controlled by ROP GTPases. Spatiotemporal activation of ROP (Rho GTPases of plants) necessitates a complex and sophisticated regulatory system, in which

Pollen-specific pectin methylesterase involved in pollen tube growth [PDF]
Pollen tube elongation in the pistil is a crucial step in the sexual reproduction of plants. Because the wall of the pollen tube tip is composed of a single layer of pectin and, unlike most other plant cell walls, does not contain cellulose or callose ...
