Abstract
Gemini particles were purified from Abutilon Mosaic Virus infected Abutilon sellovianum, Sida micrantha and Malva parviflora. They sediment with 82 S, possess a density of 1.30 g/cm3 in Cs2SO4 and a nucleic acid percentage of 18 % calculated from ultra‐violett spectrometry. Their proteins are separated in SDS‐PAGE into two components of 28 000 and 27 000 mol. wt. Their nucleic acid consists of single‐stranded circular DNA with length distribution maxima of 2 800, 2 500 and 1 300 bases for the circular molecules and 2 050, 1 850, and 1 300 bases for the correspondmg linear molecules.
