Helminthosporium: Secondary Metabolites, Southern Leaf Blight of Corn, and Biology
The recent outbreak of the southern corn blight is caused by race T of fIel1l1intlzosporiulIl lIlaydis, a species in the fungus genus Hel1l1intlzosporiU1I1 which consists of about 175 species, worldwide in distribution, on grasses. Three species of HellllintlzosporiulIl-H. lIlaydis, H. turciculIl, and H. carbonUIIl-attack corn and are placed in the genus Bipolaris. The southern corn blight fung...
متن کاملSecondary Metabolites
Secondary metabolites are organic molecules that are not involved in the normal growth and development of an organism. While primary metabolites have a key role in survive of the species, playing an active function in the photosynthesis and respiration, absence of secondary metabolites does not result in immediate death, but rather in long-term impairment of the organism’s survivability, often ...
متن کاملSecondary Alcohol Metabolites
Introduction The cardiotoxicity of doxorubicin (DOX) and other quinone-containing antitumor anthracyclines has been tentatively attributed to the formation of drug semiquinones which generate superoxide anion and reduce ferritin-bound Fe(III), favoring the release of Fe(II) and its subsequent involvement in free radical reactions. In the present study NADPHand DOX-supplemented cytosolic fractio...
متن کاملCyanobacterial Secondary Metabolites
Cyanobacteria inhabit a range of diverse and extreme habitats and have potential to produce an elaborate array of secondary metabolites with unusual structures and potent bioactivity. This review summarizes several classes of cyanobacterial secondary metabolites some of which pose a threat to human or animal health in aquatic ecosystems because of their acute toxicity. This class includes hepat...
متن کاملSecondary metabolites from marine microorganisms.
After 40 years of intensive research, chemistry of marine natural products has become a mature field. Since 1995, there are signals of decreased interest in the search of new metabolites from traditional sources such as macroalgae and octocorals, and the number of annual reports on marine sponges stabilized. On the contrary, metabolites from microorganisms is a rapidly growing field, due, at le...
