Concentration and Purification of Clover Yellow Mosaic Virus from Pea Roots and Leaves. Richard E. Ford, Professor, Botany and Plant Pathology Department, Iowa State University, Ames 50010; Phytopathology 63:926-930. Accepted for publication 4 February 1973. DOI: 10.1094/Phyto-63-926.

Pea roots contained 40-70% as much clover yellow mosaic virus as did tops 10 days after inoculation; the average over all experiments at various times after inoculation was 46%. Roots have lower phenolic content than an equal amount of foliage tissue, and purification from pea roots eliminates one differential cycle (the difficult chlorophyll removal problem) which helped minimize viral aggregation and loss.
