Accumulation of potentiometric and other dyes in haustoria of Erysiphe graminis in living host cells
Twenty-five vital fluorescent dyes were tested for accumulation in haustoria of Erysiphe graminis (DC) Merat f. sp. hordei Em . Marchai when applied to coleoptile epidermal host cells of Hordeum vulgare L . Eight of the dyes gave fluorescence to structures judged to be haustorial mitochondria . The potentiometric cyanine dyes, DiOC4 (3) and DiOC 7 (3) gave best differentiation between the putat...
متن کاملSerological Methods for Detection of Polymyxa graminis, an Obligate Root Parasite and Vector of Plant Viruses.
A purification procedure was developed to separate Polymyxa graminisresting spores from sorghum root materials. The spores were used as im-munogen to produce a polyclonal antiserum. In a direct antigen coating enzyme-linked immunosorbent assay (DAC ELISA), the antiserum could detect one sporosorus per well of the ELISA plate. In spiked root samples, the procedure detected one sporosorus per mg ...
متن کاملHost – Parasite Genetics
Host-parasite interactions often have complex dynamics. At the level of individual allele frequencies, the dynamics are difficult to predict and difficult to measure. However, aggregate properties of polymorphism, such as allelic diversity or the frequency of resistance, may be relatively easy to work with. I study this problem with computer simulations of a host-parasite model. In one example,...
متن کاملHost – Parasite Genetics
The published article may differ slightly from this version. Please check the published version for quotation and citation. Introduction Host-parasite diversity can be described in two different ways. The first is simply the observed variability among the hosts and parasites in a particular population. For example, Burdon and Jarosz (1991) classified 67 wild flax plants into 10 distinct resista...
