Abstract

Using test plants and serology six tobamoviruses of pepper (FO, Ob, P8, P11, P14 and SL) and one of eggplant (A1) were compared with common tobacco mosaic virus (TMV-WU1). WU1, A1 and FO were closely similar in their reactions inCapsicum spp. as were P14 and SL. Ob, P11 and P8 were also similar in this respect except inC. frutescens ‘Tabasco’ in which P8 differed from Ob and P11.

Using micro-precipitation tests the virus strains could be roughly divided into three serological groups: Group I consisted of WU1, group II of A1, FO, P8, P14 and SL, and group III of P11 and Ob. With ELISA group II was further divisible into two subgroups, including A1 and FO, and P8, P14 and SL.

It was concluded that similarities of strains in their reactions inCapsicum spp., were not necessarily confirmed by their serological relationships.

Samenvatting

Zes tobamovirussen uit peper (FO, Ob, P8, P11, P14 en SL) en één uit aubergine (A1) konden met behulp van toetsplanten alle van elkaar worden onderscheiden. In hun reacties inCapsicum-soorten, kwamen A1 en FO sterk overeen met elkaar en met het gewone tabaksmozaïekvirus (WU1). Ob, P11 en P8, die in dit opzicht onderling veel overeenkomst vertoonden, verschilden duidelijk van alle andere. Hetzelfde gold voor P14 en SL.

Ook met behulp van de micro-precipitatietoets konden de virusstammen in groepen worden ingedeeld. Groep I werd gevormd door WU1, groep II door A1, FO, P8, P14 en SL en groep III door P11 en Ob. Met behulp van ELISA kon groep II worden onderverdeeld in twee ondergroepen, namelijk A1 en FO enerzijds en P8, P14 en SL anderzijds.

De nauwe serologische verwantschap van A1 met FO is conform de grote overeenkomst in waardplantreacties. Hetzelfde geldt voor P11 en Ob, wanneer we alleen hun reacties inCapsicum-soorten beschouwen. P8 echter, die wat het laatste betreft meer op Ob en P11 lijkt, vertoonde serologisch meer overeenkomst met P14 en SL. WU1 verschilde serologisch zeer sterk van alle andere onderzochte virusstammen.

Geoconcludeerd kan worden dat de waargenomen overeenkomst tussen de onderzochte virusstammen in hun reacties inCapsicum-soorten niet altijd gesteund wordt door hun serologische verwantschappen.
