Corn smut is a plant disease caused by the pathogenic fungus Mycosarcoma maydis, synonym Ustilago maydis.One of several cereal crop pathogens called smut, the fungus forms galls on all above-ground parts of corn species such as maize and teosinte.
The resulting meiospores develop into a gametophyte. Both the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and female gametes produces a diploid zygote which develops into a new sporophyte.
The interaction between the two types of loops is evident in mitosis. While positive feedback initiates mitosis, a negative feedback loop promotes the inactivation of the cyclin-dependent kinases by the anaphase-promoting complex. This example clearly shows the combined effects that positive and negative feedback loops have on cell-cycle ...
For example, the hydra reproduces asexually by budding. The cells at the surface of hydra undergo mitosis and form a mass called a bud. Mitosis continues in the cells of the bud and this grows into a new individual. The same division happens during asexual reproduction or vegetative propagation in plants.
When G 2 is completed, the cell enters a relatively brief period of nuclear and cellular division, composed of mitosis and cytokinesis, respectively. After the successful completion of mitosis and cytokinesis, both resulting daughter cells re-enter G 1 of interphase. In the cell cycle, interphase is preceded by telophase and cytokinesis of the ...
An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma Bryophytes ( / ˈ b r aɪ . ə ˌ f aɪ t s / ) [ 2 ] are a group of land plants ( embryophytes ), sometimes treated as a taxonomic division , that contains three groups of non-vascular land plants: the liverworts , hornworts , and mosses .

However, there are examples of animal and human parasites where the species are dimorphic but it is the yeast-like state that is infectious. [18] The genus Filobasidiella forms basidia on hyphae but the main infectious stage is more commonly known by the anamorphic yeast name Cryptococcus , e.g. Cryptococcus neoformans [ 19 ] and Cryptococcus ...
A cellular model is a mathematical model of aspects of a biological cell, for the purposes of in silico research. Developing such models has been a task of systems biology and mathematical biology .
