“…The growth rate of A. areolatum is low and the ability of occupying the resources and niche is weaker than many other endophytic fungi present in the pine ecosystems. Previous research found that some endophytic fungi can inhibit the mycelial growth of A. areolatum and destroy the mutual symbiotic relationship between S. noctilio and A. areolatum in host trees 42 , 43 . In addition, in this experiment, the xylem tissue of P. sylvestris var.…”

Interactions between the decline of Mongolian pine woodlands and fungal communities and invasive pests in northeastern China are poorly understood. In this study, we investigated the fungal communities occurring in three tree samples: the woodwasp Sirex noctilio infested, healthy uninfested and unhealthy uninfested Mongolian pine trees. We analyzed the relationships of the Mongolian pine decline with fungal infection and woodwasp infestation. Twenty-six fungal species were identified from the sampled trees. Each tree sample harbored a fungal endophyte community with a unique structure. Pathogenic fungi richness was four times higher in infested and unhealthy un-infested trees compared to that in healthy uninfested trees. Sphaeropsis sapinea was the most dominant pathogenic fungus in the sampled Mongolian pine trees. The number of S. noctilio was higher than native bark beetles in the declining Mongolian pine trees. The invasion of the woodwasp appeared to be promoted by the fungal infection in the Mongolian pine trees. The incidence of S. noctilio infestation was higher in the fungi infected trees (83.22%) than those without infection (38.72%). S. sapinea population exhibited positive associations with within-tree colonization of S. noctilio and bark beetle. Collectively, these data indicate that the fungal disease may have caused as the initial reason the decline of the Mongolian pine trees, and also provided convenient conditions for the successful colonization of the woodwasp. The woodwasps attack the Mongolian pine trees infected by fungi and accelerated its decline.

Interactions between the decline of Mongolian pine woodlands and fungal communities and invasive pests in northeast China, are poorly understood. In this study, we investigated the fungal communities occurring in healthy uninfested, unhealthy uninfested and Sirex noctilio infested Mongolian pine and analyzed the relationship between the decline of Mongolian pine and fungal communities and woodwasp. The population number of S. noctilio was very high in the declining Mongolian pine forest. 26 fungal species identified from three tree samples. Each tree sample harbored a fungal endophyte community with a unique structure. The invasion of woodwasp appear to be promoted by the fungal community in the Mongolian pine woodlands. Pathogenic fungi richness was four times higher in infested and unhealthy uninfested compared to healthy uninfested trees. Sphaeropsis sapinea was the most dominant pathogenic fungus in Mongolian pine forest, and infested healthy Mongolian pine without wounding, but a with lower incidence of without wounding (38.72%) than wound ones (83.22%). Collectively, these data indicated that the fungal disease may have caused the initial reason of the decline of the Mongolian pine forest, and also provided convenient conditions for the successful colonization of woodwasp. The woodwasp attacked stressed Mongolian pine trees and accelerated its decline.

“…Owing to superior adaptability and survivability, A. niger is ubiquitous in nature, including in terrestrial soil (Xie et al, 2006), ocean (Li et al, 2016;Uchoa et al, 2017), the Arctic (Singh et al, 2011), and space. It also occupies a wide spectrum of habitats in plants and animals such as herb (Shreelalitha and Sridhar, 2015;Manganyi et al, 2018), shrub (Kaur et al, 2015;Liu et al, 2016), tree (Soltani and Moghaddam, 2014;Wang et al, 2019), lichen (Elissawy et al, 2019), shrimp (Liu et al, 2013;Fang et al, 2016), and marine sponge (Takano et al, 2001;Hiort et al, 2004). A. niger strain grows well in various media with different carbon sources, including glucose, bran, maltose, xylan, xylose, sorbitol, and lactose (Toghueo et al, 2018).…”

Aspergillus niger, one of the most common and important fungal species, is ubiquitous in various environments. A. niger isolates possess a large number of cryptic biosynthetic gene clusters (BGCs) and produce various biomolecules as secondary metabolites with a broad spectrum of application fields covering agriculture, food, and pharmaceutical industry. By extensive literature search, this review with a comprehensive summary on biological and chemical aspects of A. niger strains including their sources, BGCs, and secondary metabolites as well as biological properties and biosynthetic pathways is presented. Future perspectives on the discovery of more A. niger-derived functional biomolecules are also provided in this review.
