Pier Andrea Saccardo
Pier Andrea Saccardo (23 April 1845 in Treviso, Province of Treviso, Treviso – 12 February 1920 in Padua, Italy, Padua) was an Italian botany, botanist and mycology, mycologist. His multi-volume ''Sylloge Fungorum'' was one of the first attempts to produce a comprehensive list of identified fungi, using their spore-bearing structures for classification. He was elected to the Linnean Society of London, Linnean Society in 1916 as a foreign member. He also authored a color classification system that he called ''Chromotaxia'' and contributed to the Italian translation of Charles Darwin's Insectivorous Plants. Life Saccardo was born in the wine growing region of Selva di Montello to Elena Vidotto and engineer Francesco di Selva. He studied at gymnasium of the Venice seminary, the Lyceum in Venice, and then at the Technical Institute of the University of Padua from 1864. At the age of fourteen, he had already put together a herbarium and had made collections of the insects of Trevis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ' ...

Phyllosticta
''Phyllosticta'' is a genus of fungi. Many of the species in this genus are common and important plant pathogens. They typically infect the foliage and cause tannish-gray leaf spots with dark brown to purple borders. However, ''Phyllosticta'' may also infect fruit and stems. Yield loss is a common consequence of ''Phyllosticta'' infection. Representatives of the genus are found worldwide and on a wide range of plant hosts. History ''Phyllosticta'' was introduced by German mycologist Persoon in 1818 and species '' Phyllosticta convallariae'' was designated as the type species (Donk 1968). Since ''Phyllosticta'' is distinct from other genera in that family, Seaver (1922) treated it in the family ''Phyllostictaceae'' of the order Phyllostictites. Nevertheless, ''Phyllosticta'' was accommodated in the family ''Botryosphaeriaceae'' (in order Botryosphaeriales C.L. Schoch et al.) in several major studies (e.g. Crous et al. 2006; Schoch et al. 2006; Liu et al. 2012). However, the phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Described In 1876
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms.

Taxa Named By Pier Andrea Saccardo
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
