Raveneliaceae

	Raveneliaceae The Raveneliaceae are a family of rust fungi in the order Pucciniales. The family contains 26 genera and about 323 species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ....

picture info	Rust (fungus) Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales (previously known as Uredinales). An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a very narrow range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be grown easily in pure culture. A single species of rust fungi may be able to infect two different plant hosts in different stages of its life cycle, and may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinia, telia, and basidia in successive stages of reproduction. Each spore type is very host specific, and can typically infect only one kind of plant. Rust fungi are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Triphragmium Ulmariae ''Triphragmium ulmariae'' is a species of rust fungus in the family Sphaerophragmiaceae. It causes meadowsweet rust gall, which develops as a chemically induced swelling, arising from the lower surface of the meadowsweet (''Filipendula ulmaria'') leaves. Life cycle The fungus grows in the petioles and/or midribs of the perennial plant meadowsweet (''Filipendula ulmaria''), a member of the rose family Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are '' Alchemilla'' (270), ''Sorbus ..., causing swelling and distortion. Sori develop with bright orange spores. The rust's spores reach the new meadowsweet plants via air movements. The rust has a severe effect on the survival of meadowsweet seedlings.

	Lipocystis ''Lipocystis'' is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect insects. Taxonomy This genus was created by Grell in 1938.Grell K G (1938) Untersuchungen an Schizogregarinen. I. ''Lipocystis polyspora'' n. g. m. sp., eine neue Schizogregarine aus dem Fettkörper von ''Panorpa communis'' L. Arch Protistenk 91:526-545 Grell observed the parasite during his work for his PhD thesis. The only recognised species in this genus is ''Lipocystis polyspora''. Description The life cycle of this parasite occurs within the fat body of the host. Transmission is via the oro-faecal route. The infective sporozoites are fusiform. Once ingested the sporozoites invade the wall of the gut ''en route'' to the fat body. After invasion the sporozoites enlarge into rounded micronuclear meronts (nuclear diameter = 1 micron). This first round of merogony produces merozoites with small nuclei which their turn become meronts. The second generation meronts ...
