Brassinosteroids are a new class of plant hormones with a polyoxygenated steroid structure showing pronounced plant growth regulatory activity. This review covers their natural occurrence, biological and chromatographic methods for their detection, biosynthesis and metabolism, biological activity, structure-activity relationships and prospective(More)
Fine mapping and sequencing revealed 28 genes in the non-recombining haplotype containing Fhb1 . Of these, only a GDSL lipase gene shows a pathogen-dependent expression pattern. Fhb1 is a prominent Fusarium head blight resistance locus of wheat, which has been successfully introgressed in adapted breeding material, where it confers a significant increase in(More)
The association of Fusarium graminearum isolate China-9 with the dsRNA mycovirus FgV-ch9 was evaluated for hypovirulence-related traits. Single conidia-originating cultures of China-9 isolate can be associated either with high, medium or low amounts of the viral dsRNAs. At high and medium dsRNA levels, China-9 isolates exhibit reduced mycelia growth rate(More)
TMVOhioV was first described 1969 by [1] because it did break resistance of tomato breeding lines containing Tm-1- and Tm-2 resistance genes. It was obtained 1987 from Wetter (Saarbrücken, Germany) and transferred into the DSMZ-Plant Virus Collection (Braunschweig, Germany). A partial sequence of TMVOhioV, the CP gene, has been reported [11] and its(More)
alternative hypotheses have been proposed to explain the signal content of caro-tenoid-dependent ornaments (2–5). The relative importance of carotenoid acquisition per se, as influenced by foraging efficiency (24, 25), parasite effects on gut absorption (26), energetic constraints (27), and carotenoid utilization for immune function, in determining the(More)
The first call has brought together a broad spectrum of Austrian scientists (coordinator GA) focussing on the Fusarium problem. We proposed (as one part) that Austria should contribute 25% of the costs of sequencing the F. graminearum genome, but the panel felt that our proposal was too much dependent on the (in April 2002) not yet submitted proposal by US(More)
