A synthetic doubled-haploid hexaploid wheat population, SynDH1, derived from the spontaneous chromosome doubling of triploid F1 hybrid plants obtained from the cross of hybrids Triticum turgidum ssp. durum line Langdon (LDN) and ssp. turgidum line AS313, with Aegilops tauschii ssp. tauschii accession AS60, was previously constructed. SynDH1 is a(More)
The Ppd-D1 controlling photoperiod response is an important gene for wheat adaptation since it affects heading time. In the present study, three haplotypes, i.e. haplotype I without deletion, haplotype II with a 24 bp deletion, and haplotype III with two deletions of 24 and 15 bp, were identified in the upstream of the coding region in 80 Ae. tauschii(More)
It is believed that unreduced gametes with somatic chromosome numbers play a predominant role in natural polyploidization. Allohexaploid bread wheat originated from spontaneous hybridization of Triticum turgidum L. with Aegilops tauschii Coss. Unreduced gametes originating via meiotic restitution, including first-division restitution (FDR) and(More)
A pair of novel high-molecular-weight glutenin subunits (HMW-GS) 1Dx3.1t and 1Dy11*t were revealed and characterized from Aegilops tauschii Coss. subspecies tauschii accession AS60. SDS-PAGE band of 1Dx3.1t was between those of 1Dx2 and 1Dx3, while 1Dy11*t was between 1Dy11 and 1Dy12. The lengths of 1Dx3.1 t and 1Dy11* t were 2,514 bp and 1,968 bp, encoding(More)
A pair of novel high-molecular-weight glutenin subunits (HMW-GS) 1Dx5.3t and 1Dy12.1**t were revealed and characterized from Ae. tauschii accession PI554324. SDS-PAGE band of 1Dx5.3t was between those of 1Bx6 and 1Bx7, while 1Dy12.1**t with slightly faster migration rate than that of 1Dy12. The lengths of 1Dx5.3 t and 1Dy12.1** t were 2115 bp and 1986 bp,(More)
Stripe rust, caused by Puccinia striiformis f. sp. tritici (PST), is one of the most important diseases of common wheat (Triticum aestivum L.). China has the largest stripe rust epidemic areas in the world and yield losses can be large. Aegilops tauschii Coss, the D-genome progenitor of common wheat, includes two subspecies, tauschii and strangulata (Eig)(More)
The contents of nine mineral elements, including sulphur, zinc, calcium, magnesium, potassium, sodium, iron, copper and manganese in five hulless barley (Hordeum vulgare L. var. nudum Hook. f.) lines were determined by ultraviolet spectrophotometry and flames atomic absorption spectrometry (FAAS). For the determination of sulphur, the samples were dissolved(More)
Taking four wheat varieties developed by Northwest Institute of Plateau Biology, Chinese Academy of Sciences, as test materials, with the measurement of content of photosynthetic pigments, leaf area, fresh and dry mass of flag leaf, the PS II photochemistry efficiency of abaxial and adaxial surface of flag leaf and its adaptation to strong solar radiation(More)
