Core Eudicots: Dicotyledons IV
Published in Donald H. Les, Aquatic Dicotyledons of North America, 2017
Economic importance: food:Cucurbita okeechobeensis contains high concentrations of bitter cucurbitacins (tetracyclic triterpenoids), which render the fruits inedible and toxic; however, the seeds reportedly are edible; medicinal: an infusion made from the fruits of C. okeechobeensis subsp. martinezii has been used as a remedy for stomach ache; the flesh of the fruit has been used as a burn ointment; cultivation:C. okeechobeensis is cultivated as a germplasm resource because it is resistant to many plant pathogens including bean yellow mosaic virus (Geminiviridae: Begomovirus), cucumber mosaic virus (Bromoviridae: Cucumovirus), squash mosaic virus (Secoviridae: Comovirus), tobacco ringspot virus (Secoviridae: Nepovirus), tomato ringspot virus (Secoviridae: Nepovirus), and powdery mildew (Fungi: Ascomycota: Erysiphales). The species reportedly is also susceptible to watermelon mosaic 2 potyvirus (Potyviridae: Potyvirus) and zucchini yellow mosaic potyvirus (Potyviridae: Potyvirus); misc. products:C. okeechobeensis has been considered as a commercial source of cucurbitans for use as “baits” to discourage crop infestations by rootworms and cucumber beetles. The fruit flesh has been used as a soap; weeds: none; nonindigenous species: none.

Soybean mosaic virus (SMV) belongs to the genus Potyvirus and the family Potyviridae. Its main hosts that are adversely infected by SMV are mainly plants belonging to the family Fabaceae. It can also infect other economically important crops. SMV occurs in all the soybean-production areas of the world. Soybean is one of the most vital sources of edible oil and proteins and pathogenic infections cause the annual yield losses of billions of dollars. Therefore, SMV is the most important and prevalent pathogen in soybean production worldwide. SMV is a single-stranded positive-sense RNA virus and its genome is about 9.5kb that encodes at least 11 proteins [9]. SMV virion is nonenveloped, flexuous, and filamentous particle of about 720–800 nm long and 12–15 nm in diameter [10].
