CHAPTER-2 VARIABILITY AMONG THE ALTERNARIA BRASSICAE ISOLATES INTRODUCTION The chapter is mainly concerned with examining the variability among Alternaria brassicae isolates from the oilseed brassicas. Since, the oilseed brassicas are more prone to the fungal attack and thereby, resulting in reduced productivity of the oilseed. Therefore, the present investigation focuses on the studying the features such as morphological, pathological and molecular variability of Alternaria brassicae. The…

stimulate the growth of the fungus slightly in concentrations 100 ppm and 300 ppm respectively. Lower and higher concentrations slightly inhibited the growth but aluminum couldn’t stop the growth of the fungus (Table 37, Fig. 46). While (Mn , Cu and Pb) succeeded to stimulate the growth of Mucor hiemalis up to 100 ppm with variable extent of growth, but higher concentration completely prevented the growth (Table 37, Fig. 46). Nickel stimulated the growth of the fungus irregularly with…

One of which was from contamination. One section of a plate had multiple fungal growth. This means that the fungus was applied to this section twice. The applicator might have failed to realize that the fungus had already been added and then added more fungus once more. Furthermore, The lack of time is also a source of error. This is because biofilms grow more slowly than planktonic organisms, therefore, more time is needed in order…

happen in any part of an individual or animal’s body. Originally it was thought that the round red spots on the skin were caused by a worm, which is why they named it Ringworm. Later on they realized that it was not caused by a worm and was actually a fungus. Symptoms Ringworm causes a crusted and scaly rash that may appear as round red patches on the skin. It also causes patches of hair loss or scaling on the scalp, itching, and blister-like lesions. Diagnosis Ringworm is usually obvious…

3. Results 3.1. Bumblebees We recorded a total of 98 bumblebee individuals (Bombus sp.) comprising 13 species (Appendix A, Table A.1). Sixty-four individuals belonging to 12 species were identified in managed meadows, and 34 individuals belonging to 8 species in abandoned meadows. Three of the total species were cuckoo bumblebees (Bombus [Psithyrus] sp). Five species were classified as long-tongued and 8 species as short-tongued. Total species richness and number of long-tongued species were…

This study set out to demonstrate that bioluminescence in Motyxia evolved in a common ancestor and grew brighter through evolutionary time. How did they do this? Existing research had already demonstrated that 10 discovered species of Motyxia had different levels of bioluminescence. By measuring the variance in the brightness between species, the authors of the study attempted to gain an insight into how their bioluminescence evolved. An experiment was set up to measure the brightness of each…

Psilocybin is a chemical compound found naturally occurring within psilocybin containing mushrooms, such as the psilocybe cubensis and psilocybe semilanceata fungi. This compound has been consumed for thousands of years and has had a major impact on numerous societies. The history of psilocybin use dates back to at most 11,000 years ago by North African indigenous cultures. There has also been evidence of mushroom use within Mayan and Aztec ruins. Modern western mushroom use began in the…

Many homeowners know that having mold in their homes is bad, yet they are unaware of exactly how bad it is for their health. Mold can spread and grow anywhere in a home or business as long as there is oxygen and moisture present. Mold releases spores that can center your home through windows, vents, and doorways. It can also be brought into a home by attaching to clothing or a pet. Mold is most commonly found in basements that have been flooded, underneath or behind refrigerators, and underneath…

A fungus. That’s how the human race was taken out. Pathetic. Ophiocordyceps unilateralis. Also known as the zombie virus, it was discovered by British Naturalist Alfred Russel Wallace in 1859. It affected ants of the Camponotini tribe. The infected ant would leave its nest and travel to an area with the perfect temperature and humidity for fungal growth, then the ant would use its mandibles to hang on a leaf upside down until the inevitable death that would follow. Over the next one hundred and…

The polyphagous shot hole borer (PSHB) problem, originated in Asian countries, shifted from a decayed and rotting host of trees in south east Asian countries to native, nursery, fruit, and landscape tree hosts in southern California and Israel. The boring beetle and tree host could exist mutually, however, the distinct symbiotic relationship between the invasive ambrosia beetle Euwallacea and the destructive fungi Fusarium poses a potential lethal threat to specific host trees, such as avocado…
