[Influence of industrial and traffic pollution on reproduction of spermatophytes]
Abstract:
A review of studies conducted, primarily, in Europe in last 30 years that deal with influence of anthropogenic environmental pollution on functioning of reproductive and, by comparison, vegetative organs of spermatophytes is presented. In the papers considered the impacts of typical industrial and traffic pollutants (compounds of iron, zinc, copper, lead, chromium, cadmium, as well as sulfur dioxide, ozone, polycyclic aromatic hydrocarbons) on plants via soil, water, air, and precipitation have been studied. Special attention is paid to effects of heavy metals on embryological structures and processes in staminate and pistillate reproductive spheres of plants (archesporium, meiosis, sporogenesis, gametophytogenesis, morphology and functioning of gametophyte, endospermogenesis, embryogenesis). Detrimental effects of anthropogenic pollution on reproductive sphere of spermatophytes are manifested through disorder in processes of cells fission and differentiation, abnormality in structures development at early stages of morphogenesis, broadening of anomalies spectrum, decrease in pollen fertility, derangement of seed-bearing and germination.

Spermatogenesis
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
