^aSymptoms induced by CTV isolates in different hosts: Mexican lime (vein clearing and stem pitting) and sweet orange (stunting and stem pitting). Symptom intensity is scored from 1 to 3, with 1 being mild and 3 very severe. SY, seedling yellows reaction in sour orange and grapefruit; − and +, absence and presence of symptoms, respectively; N, characterization not done.
