Marantaceae
The Marantaceae are a family, the arrowroot family, of flowering plants consisting of 31 genera and around 530 species, defining it as one of the most species-rich families in its order.Kennedy, H. (2000). “Diversification in pollination mechanisms in the Marantaceae”. Pp. 335-343 in Monocots: systematics and evolution, eds. K. L. Wilson and D. A. Morrison. Melbourne: CSIROLey, A. C., and Claßen-Bockhoff, R. (2011). “Evolution in African Marantaceae - evidence from phylogenetic, ecological and morphological studies”. Syst. Bot. 36, 277–290. doi: 10.1600/036364411X569480 Species of this family are found in lowland tropical forests of Africa, Asia, and the Americas. The majority (80%) of the species are found in the American tropics, followed by Asian (11%) and African (9%) tropics. They are commonly called the prayer-plant family and are also known for their unique secondary pollination presentation. Description The plants usually have underground rhizomes or tubers. The ...

Calathea
''Calathea'' is a genus of flowering plants belonging to the family Marantaceae. They are commonly called calatheas or (like their relatives) prayer plants. About 200 species formerly assigned to ''Calathea'' are now in the genus ''Goeppertia''. Calathea currently contains around 60 species. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. The young leaves and bracts can retain pools of water called phytotelmata, that provide habitat for many invertebrates.Jalinsky, J., T.A. Radocy, R. Wertenberger, & C.S. Chaboo. 2014. Insect diversity in phytotelmata habitats of two host plants, Heliconia stricta Huber (Heliconiaceae) and Calathea lutea Schult (Marantaceae) in the south-east Amazon of Peru. Journal of the Kansas Entomological Society 87(3): 299–311. Description Foliage Calathea leaves are often large and colorfully patterned. The leaves are often variegated with brig ...

Maranta Leuconeura
''Maranta leuconeura'', also known as prayer plant, is a species of flowering plant in the family Marantaceae, native to the Brazilian tropical forests. It is a variable, rhizomatous perennial, growing to tall and broad, with crowded clumps of evergreen, strikingly-marked oval leaves, each up to long. Description The specific epithet ''leuconeura'' means "white-veined", referring to the leaves. The leaves have a habit of lying flat during the day, and folding in an erect position at night as if in prayer for evening vespers, hence the common name "prayer plant". This behaviour is an example of a diurnal rhythm. Small, white flowers appear during the growing season, although this is rarely observed in houseplants and the flowers are not of particular value in comparison to the attractive foliage. The broad leaves of the plant are oval, two-color, greenish and fairly shiny. There are spots on both sides of the leaf medium, the color of which varies depending on the variety. Th ...

Pseudomonas
''Pseudomonas'' is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 described species. The members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. Their ease of culture ''in vitro'' and availability of an increasing number of ''Pseudomonas'' strain genome sequences has made the genus an excellent focus for scientific research; the best studied species include ''P. aeruginosa'' in its role as an opportunistic human pathogen, the plant pathogen '' P. syringae'', the soil bacterium '' P. putida'', and the plant growth-promoting ''P. fluorescens, P. lini, P. migulae'', and ''P. graminis''. Because of their widespread occurrence in water and plant seeds such as dicots, the pseudomonads were observed early in the history of microbiology. The generic name ''Pseudomonas'' created for these organisms was defined in rather vague terms by Walter Migula i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudomonas Cichorii
''Pseudomonas cichorii'' is a Gram-negative soil bacterium that is pathogenic to plants. It has a wide host range, and can have an important economical impact on lettuce, celery and chrysanthemum crops. ''P. cichorii'' was first isolated on endives (''Cichorium endivia''), from which it derives its name. It produces 6-aminopenicillanic acid. Based on 16S rRNA analysis, ''P. cichorii'' has been placed in the ''P. syringae'' group. Hosts and symptoms ''Pseudomonas cichorii'' is non-host specific as it does not infect just one host. Its host range includes lettuce, pepper, celery, coffee, wheat, basil and several other host plants. Symptoms of the causal agent vary depending on the host and the area of the plant infected. In general, ''pseudomonas cichorii'' is seen to cause leaf blighting and spotting. The first appearance of symptoms involves a water soaked lesion that develops at the edge of the leaf, midvein or randomly across the leaf These lesions progressively turn black ...

Alternaria Alternata
''Alternaria alternata'' is a fungus which has been recorded causing leaf spot and other diseases on over 380 host species of plant. It is an opportunistic pathogen on numerous hosts causing leaf spots, rots and blights on many plant parts. It can also cause upper respiratory tract infections and asthma in humans with compromised immunity. Hosts and symptoms ''Alternaria alternata'' has many different hosts depending on its forma specialis. In this review, only ''Alternaria alternata'' f. sp. ''lycopersici'' (AAL) is going to be assessed. This pathogen infects only certain cultivars of tomato plants and is often referred to as Alternaria stem canker of tomato. AAL's main symptom is cankers in the stem. It resides in seeds and seedlings, and is often spread by spores as they become airborne and land on plants. It can also spread throughout other plants. Under severe infection, lesions enlarge and become coalesced causing blighting of the leaves. This symptom progression occur ...

Fusarium Oxysporum
''Fusarium oxysporum'' (Schlecht as emended by Snyder and Hansen), an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae. Although their predominant role in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the ''F. oxysporum'' complex are soil borne pathogens of plants, especially in agricultural settings. Taxonomy While the species, as defined by Snyder and Hansen, has been widely accepted for more than 50 years, more recent work indicates this taxon is actually a genetically heterogeneous polytypic morphospecies, whose strains represent some of the most abundant and widespread microbes of the global soil microflora. Genome The ' family of transposable elements was first discovered by Daboussi ''et al.'', 1992 in several ''formae speciales'' and Davière ''et al.'', 2001 ...

Radopholus Similis
''Radopholus similis'' is a species of nematode known commonly as the burrowing nematode. It is a parasite of plants, and it is a pest of many agricultural crops. It is an especially important pest of bananas and citrus, and it can be found on coconut, avocado, coffee, sugarcane, other grasses, and ornamentals. It is a migratory endoparasite of roots, causing lesions that form cankers. Infected plants experience malnutrition. History and distribution The nematode was first described from necrotic tissue in a species of ''Musa'', the banana genus, in 1891. It is one of the most important root pathogens of banana crops, causing yield losses of up to 30 to 60% in many countries.Banana Nematodes: Pests and Diseases of American Samoa. Number 9.

Meloidogyne Javanica
''Meloidogyne javanica'' is a species of plant-pathogenic nematodes. It is one of the tropical root-knot nematodes and a major agricultural pest in many countries. It has many hosts. ''Meloidogyne javanica'' reproduces by obligatory mitotic parthenogenesis (apomixis). Hosts ''Meloidogyne javanica'' is a nematode pathogen that affects over 770 species of plants (Cabi 2018). The hosts of this pathogen include both weeds and crops of economic importance. Those of economic importance include tea, grapevine, vegetables, fruit trees, cereals, and ornamentals (Cabi 2018). ''Meloidogyne javanica'' is considered an agricultural pest, as it is extremely abundant and damaging (Alford 2012). Symptoms Because there are so many different hosts for this pathogen, the symptoms are very variable. Common symptoms include abnormal leaf color, abnormal leaf form, wilting leaves, galls, swollen roots, reduced root system, dwarfing and senescence (Cabi 2018). This pathogen does the most damage w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cucumber Mosaic Virus
''Cucumber mosaic virus'' (CMV) is a plant pathogenic virus in the family ''Bromoviridae''. This virus has a worldwide distribution and a very wide host range, having the reputation of the widest host range of any known plant virus. It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion. It can also be transmitted in seeds and by the parasitic weeds, ''Cuscuta sp.'' (dodder). Hosts and symptoms This virus was first characterized in cucumbers (''Cucumis sativus'') showing mosaic symptoms in 1934, hence the name ''Cucumber mosaic''. Since then, it has been found to infect a great variety of other plants. These include other vegetables such as squash, melons, peppers, eggplants,tomatoes, beans, carrots, celery, lettuce, spinach, beets, many ornamentals and bedding plants, such as '' Narcissus'', and various weeds. Its presence has been confirmed on every continent of the world, including Antarctica. Symptoms seen with this virus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
