Responses of four citrus plants to Phytophthora-induced root rot

China is one of the largest citrus producers in Asia, where Phytophthora parasitica infection has become the major threat in sustaining long term citrus production. The proposed study examined the effects of P. parasitica on Citrus junos, C. limon, C. tangerina and Poncirus trifoliata to evaluate th...
