Article Synopsis
  • Italian ryegrass in Southwest China was affected by a disease causing black leaf spots, observed in December 2023 with less than 1% incidence in a field in Hongya County.
  • Researchers isolated a fungus from infected plants, cultivating samples on potato dextrose agar which produced cottony, whitish colonies and characteristic conidia.
  • Genetic analysis of two fungal strains (LJH17 and LJH18) confirmed their identity through sequencing of specific gene regions, with sequences submitted to GenBank for further reference.

Grasslands have been widely grazed for livestock production by cattle and sheep. However, previous studies have mainly focused on the impacts of single-species grazing on grassland biodiversity and ecosystem functions; the effects of mixed grazing of cattle and sheep remain largely unknown. We conducted a meta-analysis to examine the impacts of mixed grazing and analyzed the relative roles of cattle and sheep on grassland biodiversity and multiple ecosystem functions.

Livestock grazing is a dominant practice in alpine grasslands and plays a crucial role in the ecosystem service of the Qinghai-Tibetan Plateau. The effects of grazing on alpine grasslands highly depends on grazing intensity. Up to now, we still lack comprehensive understanding of the general responses of alpine grasslands to different grazing intensities over broad geographic scales across the Qinghai-Tibetan Plateau.

Introduction: is a cultivable fungal endophyte that lives in symbiosis with wild barley () to which it confers salt tolerance. This study tested the hypothesis that derived from wild barley has the potential to increase salt tolerance in cultivated barley under salt stress.

Methods: To test this hypothesis, the growth response, physiological parameters, and metabolic profiles of barley plants inoculated with (E+) and those not inoculated with (E-) were compared under salt stress.

Article Synopsis
  • Italian ryegrass is a well-known forage grass grown extensively in southern China, where a small outbreak of necrotic leaf spots was observed in a large field in April 2021, affecting 1-3% of the plants.
  • Researchers isolated tissue samples from affected leaves and grew fungal isolates, identifying three representative strains based on their characteristics on potato dextrose agar (PDA).
  • Genetic analysis using specific primers revealed that these isolates had over 99.7% sequence identity with a known fungal ex-type isolate, and phylogenetic analysis confirmed their close relationship to previously reported strains.

Toxic plants are a natural component of alpine meadow which co-evolved with Tibetan sheep for thousands of years. One challenge for indigenous herders is to know the ecological thresholds of toxic plants and maintain their vital functions in ways that are compatible with economic income and ecological conservation. To achieve this, field trials with Tibetan sheep grazing in alpine meadow were conducted to examine the ecological thresholds of toxic plants for sheep production and ecosystem functions and their trade-offs.
