The last stand – Plant stem cells put up a fight against viruses

Viruses are a threat to all organisms, including plants. A small group of plant stem cells, however, successfully defends itself from infection. Marco Incarbone, now at MPIMP Golm, Gabriele Bradamante and their co-authors at the Gregor Mendel Institute of Molecular Plant Biology (GMI) uncovered that salicylic acid and RNA interference mediate this antiviral immunity of plant stem cells. The findings were published in PNAS on October 12.
