Satellite (S-TRSV) of tobacco ringspot virus (TRSV) was transmitted with activator TRSV by Xiphinema americanum from cucumber to cucumber. Plants became systemically infected with both TRSV and S-TRSV after nematode transmission, developing a chlorotic mottle in young leaves. Symptoms were indistinguishable between cucumber plants infected with TRSV alone and plants with TRSV plus S-TRSV.
