Abstract:

Alkaloids produced by grass endophytic fungi have the ability to enhance resistance to a wide range of stress environments faced by the host plant. We reviewed the status and developing trends of research into alkaloids of grass endophytic fungi, based on the Web of Science database. Papers about alkaloids of grass endophytic fungi published in the past 20 years from 2000 to 2019 were retrieved and screened, with Epichlo? alkaloids or Neotyphodium alkaloids as keywords. The papers retrieved numbered 646; 33 reported domestic research in China. According to the quantitative analysis of the retrieved papers, the top three countries for the number of alkaloid publications were the United States, New Zealand and China. China was the country with the most citations on average. Over the past 20 years, the number of articles on endophytic fungal alkaloids in China has been steadily increasing, and some articles have been accepted by international journals at a high level. The laboratories researching endophytic fungi in grasses in China were mainly concentrated in Lanzhou University and Nankai University. The research outputs primarily included biological characteristics of alkaloids, ecological functions and factors affecting alkaloid production in symbionts. However, there are some studies on the mechanism of alkaloid toxicity and the biological synthetic pathways of alkaloids, which potentially could form a foundation for development of new technologies for human benefit.
