Previous research showed that the LA-toxin produced from the pathogen mainly caused the disease. In order to study its pathogenic mechanism and host resistant mechanism above cell level, the author built the interactive system between LA-toxin and slash pine suspension cell, studied the host cell shape, cell vigor during...
