Tree diversity regulates forest pest invasion [PDF]

Proceedings of the National Academy of Sciences, 2019
Nonnative pests often cause cascading ecological impacts, leading to detrimental socioeconomic consequences; however, how plant diversity may influence insect and disease invasions remains unclear. High species diversity in host communities may promote pest invasions by providing more niches (i.e., facilitation), but it can also diminish invasion ...

Predicting the Spread of Forest Diseases and Pests [PDF]

IEEE Access, 2020
Due to severe economic losses caused by forest diseases and pests in China, prediction for the spread of forest diseases and pests has become one of the most challenging and hottest issues. The most previous solutions have at least the following three disadvantages: (1) lacking effective utilization of image data; (2) only supporting one-dimensional ...

A glycoside hydrolase 12 protein from Cytospora chrysosperma triggers plant immunity but is not essential to virulence

Phytopathology Research, 2023
Phytopathogens secrete numerous effectors that facilitate their infection and colonization processes. However, the pathogenic mechanism of effectors in Cytospora chrysosperma, the causal agent of canker disease in many woody plants, remains poorly ...
