Mycosphaerella musicola was first reported from Java in 1902 and by 1962 was found in most banana growing regions of the world. Although it is spread over short distances by conidia and ascospores, over long distances it is the movement of infected germplasm such as diseased leaves and suckers that is likely to be responsible.
The Amazon leaffish reaches a maximum standard length of 8 cm (3.1 in), [1] [3] and a total length of 10 cm (3.9 in). [2] As suggested by its common name, it closely resembles a dead leaf. The flattened body and filament at the tip of the lower jaw (resembling a stalk) further enhances its similarity to a leaf.

Black sigatoka is a leaf-spot disease of banana plants caused by the ascomycete fungus Mycosphaerella fijiensis (Morelet), also known as black leaf streak. It was discovered in 1963 and named for its similarities with yellow Sigatoka, which is caused by Mycosphaerella musicola (Mulder), which was itself named after the Sigatoka Valley in Fiji .
In the United States, $2.5 to 3 million dollars are lost because of peach leaf curl. Sixty to ninety percent of peach shoots in Italy can be infected by T. deformans. [14] Although peach leaf curl is mostly manageable with fungicide spraying in dry climates, [4] improper timing or incomplete coverage of the crop can result in control failure. [11]
This disease affects strawberry plant foliage causing purple spots 1 ⁄ 8 to 1 ⁄ 4 in (3.2 to 6.4 mm) in diameter across on the upper side of the leaves. [3] At first, the whole spot is purple but as the disease matures the center of the leaf spots on older leaves become tan or gray, then almost white. Lesions on younger leaves remain light ...

These specific proteases use hydrolysis to break down gelatin through two sequential steps. The first produces polypeptide products, followed by amino acids (typically alpha amino acids). [5] The substrate in this case is gelatin, and the products are the polypeptides formed. Gelatinase binds to the substrate, gelatin, due to specificity of ...
