Mycelium of <i>Trichothecium roseum</i> Link ex Fr. was observed in Poland on the surface of separate soruses of <i>Uromyces fabae</i> (Pers.) de Bary on the leaves of <i>Vicia faba</i> L. and <i>V. faba</i> L. var. <i>minor</i>. The sourses of <i>Uromyces fabae</i> were covered by the, fruiting mycelium of <i>Trichothecium roseum</i>, which, probably, inhibited the development of its uredospores. Therefore, biological control of <i>U. fabae</i> with the use of <i>Trichothecium roseum</i> seems feasible.

Expression Of Genes

Classical analysis of obligate biotrophic fungi revealed changes of enzyme activities or the concentration of metabolites in infected areas. However, due to the intricate integration of host and parasite metabolism, it was not possible to delineate the individual contributions of the two organisms. Here, we used reverse-transcription-polymerase chain reaction to monitor expression of genes from the rust fungus Uromyces fabae and its host Vicia faba. We focused on genes relevant for amino acid and sugar uptake and metabolism in both organisms. In the fungus, mRNA for plasma membrane ATPase was detected in spores and all infection structures. Two genes for fungal amino acid transporters showed dissimilar regulation. Transcripts for one were detected during all developmental stages, whereas those of the other appeared to be under developmental control. The latter result was also obtained for the so far only hexose transporter known from U. fabae and for one gene of the thiamine biosynthesis pathway. In the host plant, transcripts for two ATPases analyzed generally declined upon infection. Sucrose synthase expression increased in leaves, but decreased in roots. Transcript levels of glucose and sucrose transporter genes appeared unchanged. Markers for amino acid metabolism did not show a uniform trend: transcripts for asparagine synthetase increased, whereas those for two amino acid transporters either decreased or increased. Our analyses revealed that not only expression of genes in the immediate vicinity of the primary infection site is altered, but infection also influences transcription of certain genes in remote organs, like stems and roots. This demonstrates alterations in the source-sink relationships.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
