Effects of Nitrogen Forms on the Growth and Nitrogen Accumulation in Seedlings.

Buffalograss [ (Nutt.) Engelm.] has become the most widely cultivated warm-season turfgrass in northern China because of its low-maintenance requirements.

Assembly of high-quality genomes of the locoweed Oxytropis ochrocephala and its endophyte Alternaria oxytropis provides new evidence for their symbiotic relationship and swainsonine biosynthesis.

Locoweeds are perennial forbs poisonous to livestock and cause extreme losses to animal husbandry. Locoweed toxicity is attributed to the symbiotic endophytes in Alternaria sect. Undifilum, which produce a mycotoxin swainsonine (SW).

Biogeographic Patterns of Leaf Element Stoichiometry of L. in Degraded Grasslands on Inner Mongolia Plateau and Qinghai-Tibetan Plateau.

Plant leaf stoichiometry reflects its adaptation to the environment. Leaf stoichiometry variations across different environments have been extensively studied in grassland plants, but little is known about intraspecific leaf stoichiometry, especially for widely distributed species, such as L. We present the first study on the leaf stoichiometry of and evaluate its relationships with environmental variables.

Host-Species Variation and Environment Influence Endophyte Symbiosis and Mycotoxin Levels in Chinese Species.

Oxytropis plants are widely distributed in the grasslands in northern China. Some Oxytropis species have been reported to contain the mycotoxin swainsonine, an alkaloid which causes poisoning in livestock, referred to as locoism. Previous studies showed that endophytic fungi (Alternaria oxytropis) symbiotically associate with these Oxytropis species to produce swainsonine.
