Abstract In plant–pathogen interaction, plants trigger reactive oxygen species (ROS) bursts to defend against pathogen invasion, while pathogens evolved antioxidant systems to scavenge ROS for infection. Our study reveals a regulatory mechanism of ROS adaptation and scavenging in the rice blast fungus Magnaporthe oryzae. We found that KatG1, a bifunctional catalase-peroxidase, acts as a ROS-responsive regulatory enzyme.

Segmentation of regions of interest (ROIs) such as tumors and bones plays an essential role in the analysis of musculoskeletal (MSK) images. Segmentation results can help with orthopaedic surgeons in surgical outcomes assessment and patient's gait cycle simulation. Deep learning-based automatic segmentation methods, particularly those using fully convolutional networks (FCNs), are considered as the state-of-the-art.
