Taxus cuspidata var. nana is a cultivated variety of Taxus cuspidata and contains taxol, a valuable secondary metabolite of medical importance, both in their stems and leaves. In this paper, random amplified polymorphic DNA (RAPD) markers were used to assess the genomic diversity of individual plants within T. cuspidata population. Seventy-four randomly(More)
Antifreeze proteins (AFPs) accumulate in the leaves of winter cereals during cold acclimation, where they may inhibit ice recrystallization during freezing and thawing cycles and provide nonspecific disease resistance. In this study, 21 wheat chromosome substitution lines and the parental lines Chinese Spring and Cheyenne wheat were used to determine the(More)
Bamboo belongs to subfamily Bambusoideae of the grass family and is one of the most important non-timber forest resources in the world. The AP2/ERF superfamily is a group of plant specific transcription factors and plays important roles in the regulation of plant growth and responses to biotic and abiotic stress. By comprehensively analyzing the recently(More)
We used the conventional and methylation-sensitive randomly amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) analyses to assess genome-wide changes and explore the relationships between genetic and epigenetic variations among individuals of a newly synthesized allohexaploid wheat line whose genomic constitution is identical to that(More)
Alkaligrass (Puccinellia chinampoensis Ohwi), one of the important forage grasses in saline-alkalieroded grasslands, has been proved to be invaluable for improving saline-alkali soils. However, little is known of its genetic instabilities during in vitro culture for its artificial breeding. In this paper, a simple and efficient regeneration system of mature(More)
The aim of this study was to determine the lowest concentration of nocodazole and colchicine to arrest blastomere division during the cleavage stage of loach embryos and to assess the reversibility and toxicity of the treatments in the treated embryos. Eight-cell loach embryos were incubated for 4, 8, 12, or 16 h in 1/10× Holtfreter supplemented with either(More)
