The genus Dasypyrum contains two species: the annual and widespread D. villosum (2x = 2n = 14) and the perennial and generally rare D. breviaristatum (2x = 2n = 14 and 4x = 2n = 28). The origin of the latter and its genome constitution have been subject of several studies. There is agreement that the genome of the diploid D. villosum (VV) is different from(More)
We investigated the ability of high concentrations of oestradiol to reverse the growth inhibitory action of tamoxifen on MCF-7 breast cancer cells in vivo. Tamoxifen inhibits the oestradiol stimulated growth of MCF-7 cells in athymic mice. Using a sustained release preparation of tamoxifen we consistently achieved serum concentrations of the drug in the 40(More)
The feasibility of genetically engineering soybean seed coats to divert metabolism towards the production of novel biochemicals was tested. The genes phbA, phbB, phbC from Ralstonia eutropha each under the control of the seed coat peroxidase promoter were introduced into soybean and the production of polyhydroxybutyrate (PHB) was assayed. The analysis of(More)
Dasypyrum is a genus with two species, an annual diploid Dasypyrum villosum and a perennial diploid or tetraploid D. breviaristatum. It is difficult to distinguish between the two, especially for a non-taxonomist. In this paper we demonstrate how to distinguish between the two species and between the two ploidy levels of D. breviaristatum. We achieve this(More)
The genus Elymus (“Ryegrass”) is a repository for a range of species with a variety of haplome contents; hence the pejorative name “dustbin” genus. We have analyzed 1,059 sequences from 128 accessions representing 24 species to investigate the relationships among the StH haplomes-containing species described by Yen and Yang (Genus Elymus Beijing 5:58–362,(More)
