Question: Fusarium oxysporum infects what fruit which is known as bitter melon or bitter gourd?
Context: Koa wilt is a relatively new disease to Hawaii, discovered in 1980.  Koa wilt is caused by the fungus Fusarium oxysporum, which is now abundant in Hawaiian soils and infects the native Acacia koa tree, a once-dominant species in the canopy of Hawaiian forests.  "F. oxysporum f.sp.  koae" is believed to have been brought into Hawaii on an ornamental acacia plant.  Fusarium fungi clog the tree xylem, causing significant wilt and mortality among these beautiful and iconic Hawaiian trees. Melon soup is a soup prepared with melon as a primary ingredient.  Melons such as bitter melon, cantaloupe, crenshaw melon, honeydew (casaba melon) and winter melon may be used, among others.  Some melon soups are prepared with whole pieces of melon, and others use puréed melon.  Some are served hot, while others are served chilled.  Some cold varieties are prepared without any cooking involved.  Several styles and varieties of melon soups exist, including bitter melon soup, cantaloupe soup and winter melon soup, among others.  The origin of some melon soup recipes may cross international boundaries. Fusarium oxysporum" f.sp.  "momordicae is a fungal plant pathogen infecting bitter gourd ("Momordica charantia" L.), resulting in fusarium wilt.  It is a "forma specialis" (f.sp.)  of "Fusarium oxysporum". Momordica charantia, known as bitter melon, bitter gourd, bitter squash, or balsam-pear, is a tropical and subtropical vine of the family Cucurbitaceae, widely grown in Asia, Africa, and the Caribbean for its edible fruit.  Its many varieties differ substantially in the shape and bitterness of the fruit.  Bitter melon also has names in other languages which have entered English as loanwords, e.g. kǔguā (苦瓜) from Chinese, nigauri (苦瓜) from Japanese, gōyā (ゴーヤー) from Okinawan, kaipakka/paavakka (കയ്പക്ക/പാവയ്ക്ക) in Malayalam, kakarakaya (కాకరకాయ) in Telugu, Hāgala (ಹಾಗಲ) in Kannada, pākal (பாகல்) in Tamil and karela (करेला and كاريلا) or kareli (करेली and کریلی) in Hindustani (Hindi and Urdu), coming from Sanskrit.  In Bengali, it is known as uchche (উচ্ছে).  Those from the Caribbean island of Jamaica commonly refer to the plant as cerasee.  In Brazil this plant is called Saint Cajetan's Melon (melão-de-são-caetano).  In Guyana the plant is referred to as corilla.  In the Philippines it is called ampalaya or amargoso.  And in the Republic of Suriname it is called "sopropo". Fusarium oxysporum f.sp.  albedinis is a fungal plant pathogen that causes a disease known as Bayoud disease or fusarium wilt primarily on dates. Fusarium wilt is a common vascular wilt fungal disease, exhibiting symptoms similar to Verticillium wilt.  The pathogen that causes Fusarium wilt is "Fusarium oxysporum" ("F. oxysporum").  The species is further divided into forma specialis based on host plant. Nufar basil ("Ocimum basilicum" 'Nufar') is the first variety of sweet basil ("O. basilicum") that is resistant to fusarium wilt.  Fusarium wilt is a disease that causes sudden wilting and death in multiple species including basil.  It is caused by the fungus "Fusarium oxysporum f. sp.  basilicum", which attacks the xylem in the stem, blocking water uptake and leading to a characteristic sudden leaf wilt that does not respond to watering. The ascomycete fungus Fusarium oxysporum    Schlecht as emended by Snyder and Hansen comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans.  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, although this last statement has not been proven or supported by actual data.  These remarkably diverse and adaptable fungi have been found in soils ranging from the Sonoran Desert, to tropical and temperate forests, grasslands and soils of the tundra.  "F. oxysporum" strains are ubiquitous soil inhabitants that have the ability to exist as saprophytes, and degrade lignin and complex carbohydrates associated with soil debris.  They are also pervasive plant endophytes that can colonize plant roots and may even protect plants or be the basis of disease suppression.  Although the predominant role of these fungi in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the "F. oxysporum" complex are pathogenic to plants, especially in agricultural settings. Bitter melon tea, also known as gohyah tea, is an herbal tea made from an infusion of dried slices of the bitter melon.  It is sold as a medicinal tea, and a culinary vegetable. Fusarium oxysporum" f.sp.  "cubense    is a fungal plant pathogen that causes Panama disease of banana ("Musa" spp.) , also known as fusarium wilt of banana.
