Plant Pathogen
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrates, or other pests that affect plant health by eating plant tissues and causing injury that may admit plant pathogens. The study of plant disease is called plant pathology. Plant pathogens Fungi Most phytopathogenic fungi are Ascomycetes or Basidiomycetes. They reproduce both sexually and asexually via the production of spores and other structures. Spores may be spread long distances by air or water, or they may be soil borne. Many soil inhabiting fungi are capable of living saprotrophically, carrying out the role of their life cycle in the soil. These are facultative saprotrophs. Fungal diseases ma ...

Myrotoxin B
Myrotoxin B is a macrocyclic trichothecene first isolated in 1985. It was tested on Swiss mice and found to be very toxic, though not the most toxic of the three toxins that were tested at that time. It has also been isolated from ''Myrothecium roridum'', a pathogen leaf spot A leaf spot is a limited, discoloured, diseased area of a leaf that is caused by fungal, bacterial or viral plant diseases, or by injuries from nematodes, insects, environmental factors, toxicity or herbicides.

Fungal Plant Pathogens And Diseases
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi'' or ' ...

Stachybotryaceae
The Stachybotryaceae are a family of fungi in the order Hypocreales; the genera it contains have been described as "hyper-diverse". The family was originally introduced by Crous et al. (2014) to accommodate three genera; ''Myrothecium'', ''Peethamabra'' and ''Stachybotrys''. It was revised by Lombard et al. (2016) based on morphological characters and multi-locus phylogenetic analysis. They accepted 33 genera in the family, including 21 new genera. Generally, the species in Stachybotryaceae are characterized by asexual morphs with mononematous to sporodochial to synnematous conidiomata, usually with phialidic conidiogenous cells that produce 0–1-septate conidia in dark green dry chains or slimy masses. Three species of Stachybotryaceae;(''Koorchalomella salmonispora'', ''Stachybotrys chartarum'' and ''Stachybotrys chlorohalonata'') have been reported from freshwater habitats. Genera As accepted in 2020 (with amount of species): Note; for ''Stachybotrys'' , 12 species have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
