IDENTIFICATION OF RUST (Puccinia helianthi Schw.) RACES IN SUNFLOWER (Helianthus annuus L.) IN TURKEY
Sunflower (Helianthus annuus L.), with its high oil quality, is one of the major and most valuable oilseed crops in the world. Sunflower rust, caused by Puccinia helianthi Schw., is one of the major foliar diseases of sunflower. The pathogen is present wherever sunflower is grown in the world and causes important yield losses when severe epidemics occur. The objective of this study was to ident...
متن کاملEffect of cations on germination & germ tube development of Puccinia coronata uredospores.
Previous work in this laboratory (20) showed that germ tubes of Puccinia coronata uredospores would form structures in vitro resembling those found in infected host plants (18). This so-called vesicle formation occurred on Difco gelatin in the pH range of 6.2 to 6.9 on addition of 14 to 22 X 10-5 M Zn. Under these conditions germ tube length was reduced, and in some cases the percentage germina...
متن کاملIdentification of the Germination Self-inhibitor from Uredospores of Puccinia striiformis
MACKO, V., E. J. TRIONE, and S. A. YOUNG. 1977. Identification of the germination self-inhibitor from uredospores of Puccinia striiformis. Phytopathology 67:1473-1474. The endogenous germination inhibitor from uredospores a germination assay employing fresh, water-washed, stripe of the stripe rust fungus, Puccinia striiformis, was identified rust uredospores. The chemical structure was confirme...
متن کاملEnzymatic transamination reactions involving arginine and ornithine.
Recent research has resulted in considerable modification of the earlier concept that enzymatic transamination was limited to reactions between alanine, aspartate, glutamate, and their or-keto analogues. Reactions leading to the reversible amination of the cY-keto analogues of many of the natural amino acids have been described (l-5), and there is also evidence that aldehyde groups may particip...
متن کاملCarbohydrate and Lipid Metabolism During Germination of Uredospores of Puccinia graminis tritici.
Uredospores of Puccinia graminis (Pers.) tritici (Eriks. and Henn.) were uniformly labeled with (14)C by permitting the host (Triticum aestivum L.) to carry out photosynthesis in (14)CO(2) during the process of spore production by the obligate parasite. The use of (14)C labeled spores provided advantages in a study of the utilization of endogenous substrates at frequent intervals with small amo...
