Fungus

The reason TYMC is such a crucial factor is because mold and yeast are considered members of the fungus family. It can be found all throughout nature, in air, soil, water, vegetation and decay. It can grow and thrive in a wide range of temperatures and pH environments, even in harsh conditions that bacteria would not be able to survive in. Unlike plants, they do not produce their own food source. Their means of survival consists of breaking down matter from their immediate environment into…

After placing themselves on the desired rye or some other species of either grains or wild grasses, it uses the plant as a host in the process of replacing the host’s reproductive organs with a sclerotium, which is created differently for each Claviceps sp. Speaking of species, the genus Claviceps have been narrowed down to sixteen species through RNA-declassifying phylogenetic trees, which Sylvie Pažoutová kindly states in the following: C. paspali, C. zizaniae, C. grohii, C. sulcata, C.…

3.2 Introduction A current goal of ecology is to understand the impacts of biological invasions on food-web structure and dynamics (Jackson et al. 2012; Simberloff et al. 2013; Lurgi et al. 2014). Research suggests that terrestrial food webs, which are depictions of biodiversity, species interactions, and ecosystem structure (Polis & Strong 1996), are dramatically altered following plant invasion (DeVore & Maerz 2014; McCary et al. 2016; Smith-Ramesh et al. 2016). For example, successful plant…

In James Serpell’s book, In the Company of Animals, chapter 2 “A cuckoo in the nest” argues that pets are not parasites, but rather live in a symbiotic relationship with their owners. Serpell starts his argument by talking about the parasitic relationship between the Atemeles beetles and ants. Through various bodily functions, the Atemeles beetles can find their way into the highly defensive ant colony. When they have successfully infiltrated the colony, they begin their attack without being…

n 1910 Citrus Canker was introduced to the United States on trifoliate rootstock seedlings that were imported Japan. The disease spread rapidly around the Gulf Coast. Starting in Texas, it made it’s way east to Florida, then north to South Carolina. The pathogen, Xanthomonas axonopodis has two pathovars known to cause Canker; one being citri, and the other being aurantifolii. These can affect all citrus cultivars and even some citrus relatives. This bacterium is not known to be harmful to humans…

Through the lecture, the professor explains why a re-examination of available information has produced new conclusions about why bioluminescence occurs in the mushroom kingdom. Although he agrees with the general information in the reading, he believes it generates alternative conclusions. The first bit of information he refutes is the idea that mushrooms emit light to attract insects to their spores. He points out that the part of the mushroom that emits light is not the same as the part that…

I was in Corn Group A for our posters we presented before Fall break. The two disease topics we covered in corn was Goss’s Wilt and Root Rot Pythium. Impact: Between Goss’s Wilt and Root Rot Pythium I believe the Root Rot Pythium has a much greater impact on a Corn plant. There is a much greater impact because the time of infection is at a much earlier time when the plant is just a seedling and has a slim chance of fighting off the necrotrophic disease. When Pythium attacks the seeding through…

Summary Baker’s yeast (Saccharomyces cerevisiae) is a unicellular organism, classified as a fungus, or an organism that lives and receives its nutrients by decomposing the organic material in its surroundings. This species is easy to use throughout laboratory tests because of their quick generation times, implementing the use of budding as a form of asexual reproduction. The naked eye can easily view the colonies that these yeast cells form, and carefully count them to determine the growth. The…

morphological identifications of fungal entomopathogens such as color of colony, mycelial characteristics and spores from all six isolates were done at microscopic level. 2.6. Molecular Characterizations of Entomopathogenic Fungi Cultures of Metarhizium fungus were grown in nutrient broth (Bacto, Australia) in 100 mm x 15 mm Petri dishes incubated at 25 ± 2 ºC at 150 rpm. The media having mycelia and conidia were centrifuged in microcentrifuge tubes and approximately 40 mg of fungal material was…

The hindbrain is located above the spinal cord and is also referred to as the rhombencephalon, it is like an extension to the spinal cord. The function of the hindbrain is primarily the coordination of motor reflexes, with the cerebellum carrying on much of this coordination (Raven et al. 2008). This part of the brain is made up of two parts the myelencephalon and the metencephalon. The medulla oblongata is located within the myelencephalon. The myelencephalon is a subdivision of the brain used…
