BACKGROUND Oxytropis ochrocephala Bunge, an indigenous locoweed species in China, poses great threats to livestock on grasslands. There is a need for further genetic study in the plants per se, for understanding the basis of its acclimation mechanism in various unfavorable environmental conditions and to implement effective control measures. Quantitative real-time reverse transcription-polymera...

The genus Oxytropis (Fabaceae) was formed from the ancient species of Astragalus presumably approximately 5.6 Ma ago in Southern Siberia. Our study summarized data on genetic diversity 69 populations 31 center origin based sequencing plastid genome markers. Most (82.6%) are characterized by high gene (0.600–1.000), which indicates a relatively stable state. Phylogenetic relationships between mo...

programs. INTRODUCTION Locoweed has been reported to be the most widespread poisonous plant problem in the Western United States. It has a substantial economic impact, and may be responsible for the loss of more than $300 million in annual income due to deaths of poisoned livestock. The major contributors to these poisonings are plants from the Astragalus (Figure 1) and Oxytropis (Figure 2) gen...

A rapid and reproducible method to determine botanical composition of forage is an ecological and economic goal for range animal ecologists. Multidimensional fluorometry previously demonstrated the possibility of a unique optical approach for accurately determining species composition of clipped and digested plant materials. Fluorometry may be used to detect toxic plants in standing crop as wel...

The paper presents a taxonomic, areographic and belt-andzonal analysis of the high-mountain flora Kurai Ridge. region in question contains 312 species plants, referred to 143 genera belonging 48 families. Analysis taxonomic structure Ridge has shown following most abundant plant families: Asteraceae , Ranunculaceae, Poaceae . For variety genera, are predominant: Carex Pedicularis, Salix Oxytrop...
