Corallomycetella Repens
''Corallomycetella'' is a genus of ascomycete fungi in the family Nectriaceae. Species of ''Corallomycetella'' are tropical, and are characterized by the formation of brightly colored rhizomorphs of their rhizostilbella-like asexual morphs. These fungi causes a number of plant diseases including 'violet root rot' of ''Theobroma cacao'', root rot of ''Carica papaya'', and 'stinking root disease' of several tropical woody plants. Two species of ''Corallomycetella'' are recognized: '' Corallomycetella elegans'' (Berk. and M.A. Curtis) C. Herrera & P. Chaverri and '' Corallomycetella repens'' (Berk. & Broome) Rossman & Samuels. '' Corallomycetella jatrophae'' is now classified under ''Corallonectria ''Corallonectria'' is a genus of ascomycete fungi in the family Nectriaceae. Species of ''Corallonectria'' are Neotropical.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (), a microscopic sexual reproduction, sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of Ascomycota are Asexual reproduction, asexual and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, yeast#Beer, brewers' and bakers' yeast, Xylaria, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (containing all of the descendants of a common ancestor). Previously placed in the Basidiomycota along with asexual species from other fungal taxa, asexual (or Teleomorph, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectriaceae
The Nectriaceae comprise a family of fungi in the order Hypocreales. It was circumscribed by brothers Charles and Louis René Tulasne in 1865. In 2020, an Outline of fungi was produced and listed 70 genera and about 1,336 species. It is a highly diverse group with a worldwide distribution and it has higher diversity in warm temperate and tropical regions (Rossman et al. 1999; Rossman 2000; Chaverri et al. 2011, Schroers et al. 2011, Hyde et al. 2014, Lombard et al. 2015,). Several authors have studied and revised the taxonomy of ''Nectriaceae'' (Petch 1938; Munk 1957; Dennis 1960; Kreisel 1969; Rossman et al. 1999; Lumbsch and Huhndorf 2010; Lombard et al. 2015; Maharachchikumbura et al. 2016b).

Rhizomorphs
Mycelial cords are linear aggregations of parallel-oriented hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called rhizomorphs (literally, "root-forms"). As well as growing underground or on the surface of trees and other plants, some fungi make mycelial cords which hang in the air from vegetation. Mycelial cords are capable of conducting nutrients over long distances. For instance, they can transfer nutrients to a developing fruiting body, or enable wood-rotting fungi to grow through soil from an established food base in search of new food sources. For parasitic fungi, they can help spread infection by growing from established clusters to uninfected parts. The cords of some wood-rotting fungi (like ''Serpula lacrymans'') may be capable of penetrating masonry. The mechanism of the cord formation is not yet precisely un ...

Theobroma Cacao
''Theobroma cacao'' (cacao tree or cocoa tree) is a small ( tall) evergreen tree in the Malvaceae family. Its seedscocoa beansare used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. Although the tree is native to the tropics of the Americas, the largest producer of cocoa beans in 2022 was Ivory Coast. The plant's leaf, leaves are alternate, entire, unlobed, long and broad. Description Flowers The flowers are produced in clusters directly on the Trunk (botany), trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink Calyx (botany), calyx. The floral formula, used to represent the structure of a flower using numbers, is ✶ K5 C5 A(5°+52) (5). While many of the world's flowers are pollinated by bees (Hymenoptera) or Butterfly, butterflies/moths (Lepidoptera), cacao flowers are pollinated by tiny flies, ''Forcipomyia'' biting midges. Using the natural pollinator ''Forcipomyia'' midges produced more fruit tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carica Papaya
The papaya (, ), papaw, () or pawpaw () is the plant species ''Carica papaya'', one of the 21 accepted species in the genus ''Carica'' of the family Caricaceae, and also the name of its fruit. It was first domesticated in Mesoamerica, within modern-day southern Mexico and Central America. It is grown in several countries in regions with a tropical climate. In 2022, India produced 38% of the world's supply of papayas. Etymology The word ''papaya'' derives from the Caribbean Taíno "paapaía" and is also the name for the plant. Some etymologists argue that the word comes from the Mayan "páapay-ya", which means "mottled sapote". However, the most commonly accepted etymology is the Taíno one, although it is possible that both word origins are interrelated. The name ''papaw'' or ''pawpaw'' is used alternatively for the fruit only in some regions, that name generally referring to ''Asimina triloba'', an unrelated tree and fruit.
