Morphology and cytology of intergeneric hybrids involvingLeymus multicaulis (Poaceae)
The morphology and meiotic behaviour of pollen mother cells were studied in hybrids involvingLeymus multicaulis (2n = 28) ×Psathyrostachys huashanica (2n = 14),L. multicaulis ×P. juncea (2n = 14), andL. secalinus

Cytogenetic and genomic relationships ofThinopyrum elongatum with twoPsathyrostachys species and withLeymus secalinus (Poaceae)
Intergeneric hybridizations were made betweenT. elongatum, and twoPsathyrostachys and fiveLeymus species. The seed set obtained onT. elongatum ×Leymus hybrids ranged from 5.65% to 20.00%, depending onLeymus speci...

Levels and distribution of allozyme and RAPD variation in populations of Elymus fibrosus (Schrenk) Tzvel. (Poaceae)
To study the magnitude and nature of genetic variation in E. fibrosus, the levels and distribution of allozyme and RAPD variations were investigated in populations collected from Finland and Russia. The results o...

Cytological and molecular characterization of a novel monogenic dominant GMS in Brassica napus L.
A novel genic male sterile (GMS) line in Brassica napus L., which was identified in 1999, was found to be controlled by a monogenic dominant gene, which we have designated as MDGMS. The microspores of the MDGMS a...

Effect of floral morphology on fruit set in Epimedium sagittatum (Berberidaceae)
The relationship between the floral morphology, especially the heterostyly, and the pollination ability in Epimedium sagittatum was investigated. Three distinct kinds of flowers were observed in this species: (1)...

The origin of Triticum petropavlovskyi Udacz. et Migusch.: demonstration of the utility of the genes encoding plastid acetyl-CoA carboxylase sequence
Single- and low- copy genes are less likely subject to concerted evolution, thus making themselves ideal tools for studying the origin and evolution of polyploid taxa. Based on the sequences of a single-copy n...

Cytoplasmic diversity in Brassica rapa L. investigated by mitochondrial markers
Brassica rapa L. is an important vegetable and oilseed crop. Cytoplasmic diversity of 36 B. rapa accessions was analyzed using the mitochondria-specific markers. Twelve representative materials i...

Characterization of an IAA-glucose hydrolase gene TaTGW6 associated with grain weight in common wheat (Triticum aestivum L.)
In rice, the TGW6 gene determines grain weight and encodes a protein with indole-3-acetic acid (IAA)-glucose hydrolase activity. Its homolog in wheat, TaTGW6, is considered as a candidate gene related to grain de...

Identification of major loci for seed dormancy at different post-ripening stages after harvest and validation of a novel locus on chromosome 2AL in common wheat
A long-period duration of seed dormancy helps to reduce pre-harvest sprouting (PHS) damage in common wheat when a long period of rainfall or high humidity occurs. Identification of genes or loci underlying see...

Open AccessAdaptation insights from comparative transcriptome analysis of two Opisthopappus species in the Taihang mountains
Opisthopappus is a major wild source of Asteraceae with resistance to cold and drought. Two species of this genus (Opisthopappus taihangensis and O. longilobus) have been employed as model systems to address the ...
