Researchers from the Virginia Bioinformatics Institute at Virginia Tech have identified the region of a large family of virulence proteins in oomycete plant pathogens that enables the proteins to enter the cells of their hosts. The protein region has the ability to carry the virulence proteins across the membrane surrounding plant cells without any additional machinery from the pathogen. Once inside the plant cell, the proteins suppress the immune system of the plant allowing the infection to progress.
