Allen-biological Activity of Uredospores

چکیده
by several observers for other rusts (2) has often been dletected in the distillates derived from stem rust uredospores. The fishy odor of fresh distillates frequently gives place upon dilution or storage to an odor more like the fragrance of flowers. If the odors and the biological activities of the preparations discussed in this paper are properties of the same compound(s), then the widespread production of odors by rusts may have some significance in the ontogeny of parasites of this group.

Purification and partial characterization of a factor in cotton wax stimulating the germination of self-inhibited wheat stem rust uredospores.
Filter paper, nonabsorbent cotton, and cotton wax were found to be progressively richer sources of germination-stimulatory activity effective in counteracting the self-inhibition of Puccinia graminis var. tritici Erikss. and E. Henn uredospores. The major stimulatory component of cotton wax was purified and partially characterized. It was catalytically effective in stimulating germination and o...

متن کاملShotgun identification of proteins from uredospores of the bean rust Uromyces appendiculatus.
We are interested in learning more about the proteome of Uromyces appendiculatus, the fungus that causes common bean rust. Knowledge of the proteins that differentiate life-cycle stages and distinguish infectious bodies such as uredospores, germlings, appressoria, and haustoria may be used to define host-pathogen interactions or serve as targets for chemical inhibition of the fungus. We have us...
متن کاملLabel-Free Quantitative Proteomic Analysis of Puccinia psidii Uredospores Reveals Differences of Fungal Populations Infecting Eucalyptus and Guava
Puccinia psidii sensu lato (s.l.) is the causal agent of eucalyptus and guava rust, but it also attacks a wide range of plant species from the myrtle family, resulting in a significant genetic and physiological variability among populations accessed from different hosts. The uredospores are crucial to P. psidii dissemination in the field. Although they are important for the fungal pathogenesis,...

One of the main factors for satellite design is simulating of total ionizing dose due to space ionizing rays in devices used in space. By measurement of induced dose based on available data in different altitudes, expenses of designing, satellite weight and amount of needed fuel will be reduced. Optimum design of satellite for protecting satellite against ionizing radiation has considerable eff...
