''Fusarium oxysporum'' f. sp. ''cubense'' is a fungus, fungal plant pathogen that causes Panama disease of banana (''Musa (genus), Musa'' spp.), also known as fusarium wilt of banana. The fungi and the related disease are responsible for widespread pressure on Banana industry, banana growing regions, destroying the economic viability of several commercially important List of banana cultivars, banana varieties. Description ''Fusarium oxysporum'' is a common inhabitant of soil and produces three types of Asexuality, asexual spores: macroconidia, microconidia and chlamydospores. The Conidium, macroconidia are nearly straight, slender and thin-walled. They usually have three or four septa, a foot-shaped basal cell and a curved and tapered apical cell. They are generally produced from phialides on Ascomycete#Asexual reproduction, conidiophores by basipetal division. They are important in secondary infection.Couteaudier, Y. and C.

Panama Disease
Panama disease (or Fusarium wilt) is a plant disease that infects banana plants (''Musa'' spp.). It is a wilting disease caused by the fungus ''Fusarium oxysporum'' f. sp. ''cubense'' (Foc). The pathogen is resistant to fungicides and its control is limited to phytosanitary measures.Ploetz, R. C. (2015). "Fusarium Wilt of Banana." Phytopathology 105(12): 1512-1521. During the 1950s, an outbreak of Panama disease almost wiped out the commercial Gros Michel banana production. The Gros Michel banana was the dominant cultivar of bananas, and Fusarium wilt inflicted enormous costs and forced producers to switch to other, disease-resistant cultivars. Currently, a new outbreak of Panama disease caused by the strain Tropical Race 4 (TR4) threatens the production of the Cavendish banana, today's most popular cultivar. Overview Although fruits of the wild bananas (''Musa'' spp.) have large, hard seeds, most edible bananas are seedless. Banana plants are therefore propagated asexually ...

Banana
A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus ''Musa''. In some countries, bananas used for cooking may be called "plantains", distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind, which may be green, yellow, red, purple, or brown when ripe. The fruits grow upward in clusters near the top of the plant. Almost all modern edible seedless ( parthenocarp) bananas come from two wild species – ''Musa acuminata'' and ''Musa balbisiana''. The scientific names of most cultivated bananas are ''Musa acuminata'', ''Musa balbisiana'', and ''Musa'' × ''paradisiaca'' for the hybrid ''Musa acuminata'' × ''M. balbisiana'', depending on their genomic constitution. The old scientific name for this hybrid, ''Musa sapientum'', is no longer used. ''Musa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Rice
Brown rice is a whole grain rice with the inedible outer Rice hulls, hull removed. This kind of rice sheds its outer hull or husk but the bran and germ layer remain on, constituting the brown or tan colour of rice. White rice is the same grain without the hull, the Rice bran, bran layer, and the cereal germ. Red rice, Oryza glaberrima#American cultivars, gold rice, and black rice (also called purple rice) are all whole rices with differently pigmented outer layers. Cooking time Brown rice generally needs longer cooking times than white rice, unless it is broken rice, broken or flour blasted (which perforates the bran without removing it). Studies by Gujral and Kumar in 2003 estimated a cooking time between 35 and 51 minutes. A shorter cooking time is necessary for "converted" or parboiled rice. Storage Brown rice has a shelf life of approximately 6 months, but hermetic storage, refrigeration or freezing can significantly extend its lifetime. Freezing, even periodically, can al ...
