Dimorphism in Ceratocystis minor var. barrasii
Mycopathologia
|December 31, 1977
Abstract:
Ceratocystis minor var. barrasii, a fungus associated with the southern pine beetle, Dendroctonus frontalis, exhibits dimorphism which is influenced by the concentration of both carbon dioxide and phosphate. The mycelium produces blastospores from the tips and sides of its hyphae when the concentration of carbon dioxide is high, and these blastospores germinate if the concentration of phosphate is above about 10(-2) mM, whereas below this concentration they bud.

01:46Types of Selection
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
03:40Introduction to Seed Plants
Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms.
01:27Diversity of Protists III
Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...
