A DESYNAPTIC MUTANT IN AVENA STRIGOSA
Canadian Journal of Genetics and Cytology, 1965A strain of diploid oats, Avenn stl-igosn Schreb. (2n = 14) C.I. 4748, was crossed with its autotetraploid form (2n = 28) produced by colcl~icine treatment. T h e F, triploid ss were reoularlv forrned. I L1 i This plant proved to be heterozygous for a gene which in the recessive condition was responsible for partial desynapsis.

Suppressive effect of black oat, Avena strigosa , KH1a on Meloidogyne spp.
Nematology, 2018Summary The suppressive effect of a black oat, Avena strigosa, breeding line KH1a on Meloidogyne spp. was examined in pot tests and on Meloidogyne incognita in pot and field tests. In pot tests, roots of black oats were examined 42-46 days after inoculation of 500 second-stage juveniles.

Assignment of oat linkage groups to microdissected Avena strigosa chromosomes
Theoretical and Applied Genetics, 2002Microdissection of metaphase chromosome preparations of diploid oat Avena strigosa (2n = 14) allowed isolation of the three individual chromosomes with distinct morphologies, numbers 2, 3 and 7. Using a PCR approach based on the DNA of microdissected chromosomes, STS derivatives of RFLP markers, genetically mapped in Avena spp.

A SECONDARY TRISOMIC IN AVENA STRIGOSA
Canadian Journal of Genetics and Cytology, 1970The pairing behaviour of the chromosomes and the morphology of a secondary trisomic plant is briefly described. The plant was male and female sterile caused presumably by a deleterious dosage effect.

Meiotic chromosome association in diploid and tetraploid Avena strigosa Schrel.
Genome, 1989In diploid Avena strigosa the frequency and distribution of open (rod) bivalents suggest that a limited number of chromosomes, possibly two, fail to have a chiasma in one (short) arm in over 60% of the cells. In the tetraploid these are expected to form bivalents instead of quadrivalents at metaphase I of meiosis in a high frequency.

Canadian Journal of Genetics and Cytology, 1975
A set of seven primary trisomics and seven derived types were produced in Avena strigosa Schreb., a diploid oat species. Each trisomic type had a distinct phenotype. The primary trisomics were identified on the basis of plant and chromosome morphology. Although fertility (seed-set) and the frequency of transmission of the extra chromosome varied among ...

First report of leaf blight of Avena strigosa caused by Pyrenophora avenicola in Japan.
Plant DiseaseBlack oat (Avena strigosa Schreb.) is used as a cereal crop, forage crop or green manure in temperate regions. In Japan, it is mainly cultivated in Hokkaido island and, because of the vigorous initial growth and ability to suppress the proliferation of ...

Avenaol, a germination stimulant for root parasitic plants from Avena strigosa
Phytochemistry, 2014Root exudates from the allelopathic plant, black oat (Avena strigosa Schreb.), were found to contain at least six different germination stimulants for root parasitic plants, but no known strigolactones (SLs). One of these germination stimulants was purified and named avenaol.

Isolation and mapping of resistance gene analogs from the Avena strigosa genome
Theoretical and Applied Genetics, 2004Degenerate primers based on conserved regions of the nucleotide binding site (NBS) domain (encoded by the largest group of cloned plant disease resistance genes) were used to isolate a set of 15 resistance gene analogs (RGA) from the diploid species Avena strigosa Schreb. These were grouped into seven classes on the basis of 60% or greater nucleic acid
