Antiviral defense in plants refers to the molecular mechanisms plants use to detect, suppress, and resist viral infections, including RNA silencing pathways, innate immune responses, and resistance gene activation. Unlike animals, plants lack adaptive immunity and must rely on these cell-autonomous and systemic strategies to limit viral spread throughout their tissues. Understanding these defense mechanisms is critical for developing virus-resistant crop varieties and protecting agricultural yields from devastating plant viral diseases.
