Increased disease resistance and enzyme activity induced by ethylene and ethylene production of black rot infected sweet potato tissue.
Exposure of root tissue from a susceptible variety of sweet potato to low concentrations of ethylene induced a resistance to infection by Ceratocystis fimbriata and an increase in the activity of peroxidase and polyphenoloxidase in the tissue. Susceptible tissue that was inoculated with a pathogenic strain of C. fimbriata or a nonpathogenic strain that can induce resistance liberated more ethyl...
متن کاملAnalytical study of ipomeamarone & chlorogenic acid alterations in sweet potato roots infected by Ceratocystis fimbriata.
Several metabolic alterations have been studied, from biochemical and pathological viewpoints, in sweet potato roots infected by the black rot fungus, Ceratocystis finbriata (2, 11, 13), among which the formation of ipomeamarone is of particular interest. Because this substance is a unique furanoterpenoid produced by host tissues in response to infection, and because it has remarkable biologica...
متن کاملPhysiology and Pathogenicity of the Cucurbit Black-rot Fungus^
The black-rot fungus, Myeosphaerella melonis (Pass.) Chiu and J. C. Walker, was first reported in France in 1891 on leaves of a Chinese variety of cucumber {CueUQyiis sativus L.) (¡^i) .^ It was recorded the next year from Delaware on vines of watermelon {Gitrullus vulgaris Sehr ad.), squash {Cucúrbita spp.), pumpkin {Cucúrbita pepo L.), muskmelon {Cucumis meló L.), and cucumber {3).

متن کاملCyanide-resistant Respiration in Fresh and Aged Sweet Potato Slices.
The respiration of fresh sweet potato (Ipomoea batatas) slices is resistant to, and often stimulated by, cyanide and antimycin A. m-Chlorobenzhydroxamic acid (CLAM), a selective inhibitor of the alternate path, inhibits respiration in the presence of cyanide and has a limited inhibitory effect in the presence of antimycin A. Thus, a partial bypass of the antimycinsensitive site is indicated. Re...
متن کاملStudy of Ulcer Protective Effect of Ipomea batatas (L.) Dietary Tuberous Roots (Sweet Potato)
Peptic ulcer is one of the most prevalent gastrointestinal disorder, commonly occurs in developed countries. The present work was carried out to evaluate antiulcer effect of Ipomoea batatas (L) dietary tuberous roots. The Ethanolic extract of Ipomoea batatas (EEIB) was prepared by dynamic maceration for 7 days at room temperature using 70% ethanol (V/V). The antiulcer activity was evaluated...
