2.4.3.1. Fusarium Spp. : - is one of the most important genera of plant pathogenic fungi‚ with a record of devastating infections in many kinds of economically important plants. The genus Fusarium belongs to the Ascomycota phylum‚ Ascomycetes class‚ Hypocreales order‚ while the teleomorphs of Fusarium species are mostly classified in the genus Gibberella‚ and for a smaller number of species‚ Hemanectria and Albonectria genera (Moretti‚ 2009). Unlike most Aspergillus spp. and Penicillium spp.‚ Fusarium

Bacteria Introduction Unstained bacteria are difficult to observe because of the lack of contrast between the cells and the surrounding. To see them in an unstained state and also to observe their motility‚ a hanging-drop or a wet mount technique is used. A wet mount is the technique of placing small amounts of specimen in a droplet of water for viewing with the compound microscope. Motility is an inheritable phenotype and is critical for identification and classification of bacteria. The technique

INTRODUCTION A. BACKGROUND OF THE STUDY Molds are species of fungi. There are many different kinds of molds‚ some of which are specially adapted to grow in particular environments or on particular surfaces. Unlike plants‚ molds cannot produce their own food‚ so they need an external source of energy and nutrients. Molds (and mildew) are fungi. Fungi are neither plant nor animal but‚ since 1969‚ have their own kingdom. The fungi kingdom includes such wonderful organisms as the delicious edible

They lives within and on most living and nonliving things. The majority of bacteria’s are harmless and beneficial to the human body but some can cause infectious diseases. A bacterium usually affects one part of the body and doesn’t spread across or through the body. Bacterial infections

develop within the roots of this plant and eventually undergo symbioses. Fortunately‚ these mycorrhizal fungi form mutualistic relationships; which will enable the plant to absorb a sufficient amount of water‚ consume nutrients from the soil‚ and prevent pathogens from harming the roots. An experiment on the germination and seed production will be conducted with and without the use of the mycorrhizal fungi to determine its level of influence on the Asclepias californica plant’s progress. The plants will
