Beet Leaf Curl Virus
Beet leaf curl virus (BLCV) is a plant pathogenic virus of the family Rhabdoviridae. The host range for this virus includes species of '' Atriplex'', '' Beta'', ''Chenopodium'' and ''Spinacia'' and also ''Tetragonia tetragonioides''. The most important hosts however are sugarbeet A sugar beet is a plant whose root contains a high concentration of sucrose and which is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet (''Beta vulgaris''). Together wit ... and fodder beet. BLCV is found in the Czech Republic, Germany, Poland, Slovakia, Slovenia and Turkey. The vector for BCLV is '' Piesma quadratum'', the beet lace bug. Both adults and nymphs acquire the virus when feeding continuously for at least thirty minutes and need to feed for at least forty minutes in order to inoculate the virus into new host plants. The vectors remains infective for the rest of their lives.Proeseler, G. (1983) Beet leaf curl vir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhabdoviridae
''Rhabdoviridae'' is a family of negative-strand RNA viruses in the order ''Mononegavirales''. Vertebrates (including mammals and humans), invertebrates, plants, fungi and protozoans serve as natural hosts. Diseases associated with member viruses include rabies encephalitis caused by the rabies virus, and flu-like symptoms in humans caused by vesiculoviruses. The name is derived from Ancient Greek , meaning rod, referring to the shape of the viral particles. The family has 40 genera, most assigned to three subfamilies. Structure The individual virus particles (virions) of rhabdoviruses are composed of RNA, protein, carbohydrate and lipid. They have complex bacilliform or bullet-like shapes. All these viruses have structural similarities and have been classified as a single family. The virions are about 75 nm wide and 180 nm long. Rhabdoviruses are enveloped and have helical nucleocapsids and their genomes are linear, around 11–15 kb in length. Rhabdoviruses c ...

Atriplex
''Atriplex'' () is a plant genus of about 250 species, known by the common names of saltbush and orache (; also spelled orach). It belongs to the subfamily Chenopodioideae of the family Amaranthaceae ''s.l.''. The genus is quite variable and widely distributed. It includes many desert and seashore plants and halophytes, as well as plants of moist environments. The generic name originated in Latin and was applied by Pliny the Elder to the edible oraches. The name saltbush derives from the fact that the plants retain salt in their leaves; they are able to grow in areas affected by soil salination. Description Species of plants in genus ''Atriplex'' are annual or perennial herbs, subshrubs, or shrubs. The plants are often covered with bladderlike hairs, that later collapse and form a silvery, scurfy or mealy surface, rarely with elongate trichomes. The leaves are arranged alternately along the branches, rarely in opposite pairs, either sessile or on a petiole, and are sometim ...

Beta (plant)
''Beta'' is a genus in the flowering plant family Amaranthaceae. The best known member is the common beet, ''Beta vulgaris'', but several other species are recognised. Almost all have common names containing the word "beet". Wild ''Beta'' species can be found throughout the Atlantic coast of Europe, the Mediterranean coastline, the Near East, and parts of Asia including India. Description This genus consists of annual, biennial, or perennial species, often with fleshy, thickened roots. The stems grow erect or procumbent. The alternate leaves are petiolate or sessile, with ovate-cordate to rhombic-cuneate leaf blades, their margins mostly entire, with obtuse apex. The inflorescences are long spikelike cymes or glomerules. Bracts can be leaflike (''Beta macrorhiza'') or very small, the upper half of the inflorescence often without bracts. The bisexual flowers consist of (3-) 5 basally connate perianth segments (either greenish, dorsally ridged and with hooded tips, or petaloi ...

Chenopodium
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascen ...

Spinacia
''Spinacia'' is a flowering plant genus in the subfamily Chenopodioideae of the family Amaranthaceae. The most common member is spinach. Description The species in genus ''Spinacia'' are annual or biennial herbs. Plants are always glabrous. Their stems grow erect and are unbranched or sparsely branched. The alternate leaves consist of a petiole and a simple blade. The basal leaves are often forming a rosette. The leaf blade is triangular-hastate to ovate, sometimes with elongated lobes, with entire or dentate margins and an acute apex. The plants are usually dioecious, (rarely monoecious). The male flowers are in glomerules forming interrupted terminal spike-like panicles. They consist of 4-5 oblong perianth segments and 4-5 stamens. Female flowers are in glomerules sitting in the leaf axils. Enclosed by 2 accrescent or united bracteoles, without perianth, they consist of an ovary with 4-5 filiform stigmas. In fruit, bracteoles become enlarged and hardened, sometimes with d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetragonia Tetragonioides
''Tetragonia tetragonioides'', commonly called New Zealand spinach, Warrigal greens and other local names, is a flowering plant in the fig-marigold family (Aizoaceae). It is often cultivated as a leafy vegetable. It is a widespread species, native to eastern Asia, Australia, and New Zealand. It has been introduced and is an invasive species in many parts of Africa, Europe, North America, and South America. Its natural habitat is sandy shorelines and bluffs, often in disturbed areas. It is a halophyte and grows well in saline ground. Description The plant has a trailing habit, and will form a thick carpet on the ground or climb through other vegetation and hang downwards. It can have erect growth when young. The leaves of the plant are 3–15 cm long, triangular in shape, and bright green. The leaves are thick, and covered with tiny papillae that look like waterdrops on the top and bottom of the leaves. The flowers of the plant are yellow, and the fruit is a small, hard c ...

Sugarbeet
A sugar beet is a plant whose root contains a high concentration of sucrose and which is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet (''Beta vulgaris''). Together with other beet cultivars, such as beetroot and chard, it belongs to the subspecies ''Beta vulgaris'' subsp. ''vulgaris.'' Its closest wild relative is the sea beet (''Beta vulgaris'' subsp. ''maritima''). Sugar beets are grown in climates that are too cold for sugar cane. The low sugar content of the beets makes growing them a marginal proposition unless prices are relatively high. In 2020, Russia, the United States, Germany, France and Turkey were the world's five largest sugar beet producers. In 2010–2011, Europe, and North America except Arctic territories failed to supply the overall domestic demand for sugar and were all net importers of sugar. The US harvested of sugar beets in 2008. In 2009, sugar beets accounted for 20% of the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tingidae
The Tingidae are a family of very small () insects in the order Hemiptera that are commonly referred to as lace bugs. This group is distributed worldwide with about 2,000 described species. They are called lace bugs because the pronotum and fore wings of the adult have a delicate and intricate network of divided areas that resemble lace. Their body appearance is flattened dorsoventrally and they can be broadly oval or slender. Often, the head is concealed under the hood-like pronotum. Lace bugs are usually host-specific and can be very destructive to plants. Most feed on the undersides of leaves by piercing the epidermis and sucking the sap. The then empty cells give the leaves a bronzed or silvery appearance. Each individual usually completes its entire lifecycle on the same plant, if not the same part of the plant. Most species have one to two generations per year, but some species have multiple generations. Most overwinter as adults, but some species overwinter as eggs or ...
