The mating system of the fungus Cryphonectria parasitica: selfing and self-incompatibility

Article Abstract:

Selfing and self-incompatibility in the mating system of the fungus Cryphonectria parasitica, a haploid ascomycete, are discussed. Little has been known about how fungi reproduce in nature. In a study, frequent selfing was seen in nature, but selfing is rare in the laboratory. The mating system seems to be under ecological as well as genetic control.

Cooperation and conflict in the evolution of multicellularity

Article Abstract:

Cooperation and conflict in the evolution of multicellularity are discussed in this short review article. Evolution of conflict modifiers is a prerequisite to emergence of individuality and continued well being of an organism. Conflict, through evolution of adaptations that lower it, leads to more individuality and harmony for the organism.

Genetic relationship among Eurasian and American Larix species based on allozymes

Article Abstract:

Genetic relationships among seven Eurasian and three American Larix species is discussed, based on analysis of 16 allozyme loci. Results indicate that there is a clear separation between American and Eurasian species, as recent paleontology results also show.
