TASVd0-2,TASVd0-3,TASVd0-5,TASVd0-6,TASVd0-7,ISF RPLD
Pathway not proven. There is experimental evidence of tomato seed being a possible pathway. This viroid has been detected on seed, but evidence of transmission was not shown. All other research on seed as a pathway experimental only. Seed transmission is not conclusive.
Yes
RT- PCR
Though seed transmission is not conclusive, commercial testing is available. NAKT has validated the RT-PCR protocol.
