John Axel Nannfeldt
John-Axel Nannfeldt (baptized ''Johan Axel Frithiof Nannfeldt''), born 18 January 1904 in Trelleborg and deceased 4 November 1985 in Uppsala, was a Swedish botanist and mycologist. Nannfeldt studied natural history at the University of Uppsala and obtained a doctorate degree in 1932. He became professor of botany at Uppsala University in 1939, a position he held until his retirement in 1970. He did numerous studies on the systematics of fungi and vascular plants. Among the groups he treated were the plant pathogenic rust fungi, smut fungi and ''Exobasidium''. He also treated taxonomy and biogeography of various groups of vascular plants, e.g. the arctic '' Poa laxa'' complex. Nannfeldt published the exsiccate work ''Fungi Exsiccati Suecici, praesertim Upsalienses'' together with Lennart Holm and others. He was elected member no. 983 of the Royal Swedish Academy of Sciences in 1955. The fungal genus ''Nannfeldtiella'' was named in his honour by Franz Petrak in 1947, (now ...

Fungal Plant Pathogens And Diseases
A fungus ( : fungi 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 a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
