Cacao Necrosis Virus
''Cocoa necrosis virus'' (CoNV) is a plant pathogenic virus of the genus ''nepovirus'' that infects ''Theobroma cacao'' en natura causing cacao necrosis disease. CoNV is considered synonymous with Strain S of cacao swollen shoot virus. Unlike ''Cacao swollen shoot virus'', it is not transmitted by mealybugs nor vectored by aphids, beetles, or leafhoppers that also commonly infest cacao. It is serologically, distantly related to ''Tomato black ring virus'' and very distantly related to ''Grapevine chrome mosaic virus''. Hosts and symptoms Cacao necrosis virus is restricted to systemic infection of ''Theobroma cacao'' in nature. Symptoms on cacao include an acute stage showing translucent veinal necrosis of leaves, necrotic or chlorotic spots of leaves, defoliation, and dieback of shoots that rarely leads to seedling death if infected by the Ghanaian isolate."Cocoa""Pests of Cocoa" A following recovery phase of live plants shows limited leaf symptoms. The virus has been transmitted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narcissus (plant)
''Narcissus'' is a genus of predominantly spring flowering perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil,The word "daffodil" is also applied to related genera such as ''Sternbergia'', '' Ismene'' and '' Fritillaria meleagris''. It has been suggested that the word "Daffodil" be restricted to the wild species of the British Isles, ''N. pseudonarcissus''. narcissus, and jonquil are used to describe all or some members of the genus. ''Narcissus'' has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white and yellow (also orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona. ''Narcissus'' were well known in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his ''Species Plantarum'' (1753). The genus is generally considered to have about ten sections with approximate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant- parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time. A 2013 survey of animal biodiversity published in the mega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
