Graft-transmissible citrus diseases in P. R. China-research developments


In the P.R. China, ten graft-transmissible pathogens have been identified towards citrus, including Candidatus Liberibacter asiaticus, Citrus tristeza virus (CTV), Citrus tatter-leaf virus (CTLV), Citrus exocortis viroid (CEVd), Citrus yellow vein clearing virus (CYVCV),Satsuma dwarf virus (SDV), Citrus vein enation virus (CVED), Citrus psorosis virus (CPsV), Citrus cachexia viroid (CCaVd) and Citrus chlorotic dwarf virus (CCDV).
