1 The lower fungi comprise the groups Chytridiomycetes Oomycetes and Zygomycetes .

2 Oomycetes in Ningxia were investigated and classified. It was found that there were 67 species, hosting in 176 plants, respectively, which belonged to 1 phylum, 1 class, 4 families, 10 genera.

3 They also produce gametes in gametangia ; oomycetes are distinguished by their large immobile egg cells.

4 Of the six fungal classes only the oomycetes usually have a diploid vegetative state.

5 Oomycetes and chytrids ( sometimes called water molds ) produce motile, flagellated spores in sporangia.

6 Avr genes have been cloned from a variety of pathogens including fungi, bacteria, viruses and oomycetes.

7 The bactericidal composition is used for preventing and curing a plurality of plant diseases caused by pathogenic fungi such as oomycetes, ascomycetes, basidiomycetes and deuteromycetes.
