Effect 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 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...
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 کاملProtein and Ribonucleic Acid Synthesis during Germination of Uredospores.
Existing evidence suggests that there is no net synthesis of protein during germination of spores of some obligate parasites. The problem was reinvestigated with enzymatic hydrolysis, rather than acid hydrolysis or solubility properties, to estimate changes in protein and RNA. Procedures are detailed for the use of uniformly labeled (14)C-uredospores for the isolation and quantitative assay of ...
متن کاملOn the taxonomy of Puccinia coronata in Iran
In the present study, infra specific taxonomy of Puccinia coronata in Iran was studied. Based on morphological characters only, four P. coronata varieties were recognized in Iran. These are: P. coronata var. coronata, P. c. var. avenae, P. c. var. hordei and P. c. var. golestanica var. nov. Descriptions of the four varieties and their host range are provided. Several new hosts for aecial and te...
