Crown rust is the most damaging disease of cultivated oat (Avena sativa) and genetic resistance is the primary means of controlling the disease. Quantitative trait loci (QTL) with major and minor effects have been identified in Ogle1040 and TAM O-301 (most notably, Pc58 and PcNQMG/LGCG from TAM O-301 and OT-27 from Ogle1040) through single-isolate greenhouse and field tests. To map loci and det...

marker analysis suggests that it is also closely related to perennial ryegrass, Lolium perenne L. (Xu and Sleper, Meadow fescue (Festuca pratensis Huds.) is a pasture grass that 1994). It hybridizes readily with both perennial and Italhas been little used in North America since the introduction of its higher yielding relative, tall fescue (F. arundinacea Schreb.). The ian ryegrass, L. multiflor...

significant role in the rejection of the pathogen,i'2) Avenalumins consist of 3 components; the chemical structure ef the major component, avenalumin t, has been established to be 2-[2-(4hydroxyphenyl)ethenyl]-6-4H-3,1-benzoxazin-4-onc (1), based on an MS analysis of its acetylated derivative and identification of the methanolysis products.3) However, chem{cal studies by Crombie and Mistry4) ha...

Needle pathogens of larch (Larix spp.) in the Nordic countries are under-studied. Their incidence in Finland tends to be low and local, and this may be a function of enemy release, since species of larch were introduced to the region. Here, the ecology and incidence of larch needle pathogens and the abiotic factors that also affect larch in northern Finland are reviewed. Field observations and ...

Cell culture and genetic engineering techmques can be used to develop improved pasture plants. To utltise these methods we have developed procedures for regenerating plants from tissue cultures of perennial ryegrass and white clover. In both, the plant genotype influences regeneration capacity. There was significant genetic variation among regenerated perennial ryegrass plants in a wde range of...

Abstract Dubbed a safer C, Rust is modern programming language that combines memory safety and low-level control. This interesting combination has made very popular among developers there growing trend of migrating legacy codebases (very often in C) to Rust. In this paper, we present C translation approach centred around static ownership analysis. We design suite analyses infer models pointers ...

ABSTRACT Crown rust of barley, caused by Puccinia coronata var. hordei, occurs sporadically and sometimes may cause yield and quality reductions in the Great Plains region of the United States and Canada. The incompletely dominant resistance allele Rpc1 confers resistance to P. coronata in barley. Two generations, F(2) and F(2:3), developed from a cross between the resistant line Hor2596 (CIho ...
