Spore

This was a multi-week experiment that involved sowing the fern spores in nutrient agar. This allowed for observation and analysis of the life cycle of the C-Fern. With this the experiment could form genetic predictions based on the patterns observed. The cells of the fern are diploid, they contain two sets of chromosomes. The plant is in the sporophyte generation of it life cycle. At some point within the sporophyte plant a few of the cells will divide by meiosis and they will be haploid cells

lot of rain; therefore, the development of mold is supported. Some of professors and students think UHD might be contaminated with molds because a lot of UHD students have cough and wheezing in this fall semester. Moreover, there is the exposure of spores inside the research laboratory. The exposure of

need to make time that day to clean and remove the mold. If you let the mold continue to sit in your fridge, the spores can easily spread and ruin additional food in your fridge. Make Sure You Protect Yourself Mold spores affect each individual differently. Although the mold spores found on food are not generally toxic to humans, it doesn’t mean you should be breathing in the spores. You may want to wear a mask as well

For my parasite I picked Ophiocordyceps unilateralis or the zombie ant fungus. This fungus infects tree dwelling carpenter ants in tropical rainforests and forces them to do its biding. The parasitic fungus spreads itself around by releasing spores into the air like most fungi. The catch is that to be able to mature itself to the point of passing along its offspring it has to sacrifice an ant. Once an ant has become infected it behaves very bizarrely. The fungus forces the ant to crawl out to the

experiment with two spore-sown petri dishes, one control and one treatment – a normal nutrient-rich agar petri dish and an ammonium nitrate-containing petri dish respectively. The two petri dishes were each inoculated with three drops of spore suspension by a pipet, then spores were spread by a sterilized-bent paper clip to allow even distribution of spores. Gametophyte germination occurred approximately two weeks after inoculation for the control, and gametophyte germination occurred

Disease Risk Profiles Introduction: As the world progress in the trade and rapid human movement from one place to another, the spread of pathogens also progresses (WHO, 2001). There are many ways that a pathogen can get into a new country. Usually the entry of pathogen into New Zealand is less due to its geographical location. But, there are pathogens getting into the country. This might be because of an undetectable pathogen, pathogens with no symptoms and other related reasons. For better

staining of resting spores. The methods above are time consuming. A PCR technique was developed in western canada in 2007 that can detect the pathogen in plant tissue or in the soil. This technique has made it into commercial use. Unfortunately the techinique can only detect the presence of the pathogen not the amount of innoculum that is present in the soil. Detection with quantitative PCR appears to hold the most promise. A method has been developed that can quantify resting spores of Plasmodiophora

The stereotypical ”Zombie Ant” , most typically found in a rain forest and or farm climate, are not the flesh tearing type of zombie you most likely had in mind, instead, fungal-spreading mind controlled ants, taken over by a fungal parasite. And these ants, are far from usual. There is a cycling, almost endless process, repeated in three stages. The process and fungus is called Ophiocordyceps Unilateralis. During the first faze, the fungal parasite picked up by the target ant, enters the ant’s

has insecticidal property towards Macrotermes gilvus. Cercospora was a form genus of imperfect fungi with long slender spores that cause plant diseases, and

(b) Black masses of spores that develop inside individual male florets and (c) Masses of black spores in place of the normal ear, leaving the vascular bundles exposed and shredded. 2.1.19. False head smut: Ustilaginoidea virens is the causal organism for this disease. False head smut occurs very rarely in hot,
