摘要：RNA of a common strain of tobacco mosaic virus was sequentially reconstituted first with protein of the same strain and then with protein of a tomato strain. The reconstituted particles were treated with specific antibodies against the two strain particles and were examined electron microscopically to locate the regions of rods encapsidated with the respective proteins. The results demonstrated that reconstitution starts at an internal region of the RNA about 830 nucleotides from an end that recent studies indicate to be the 3' terminus. Evidence was obtained to show that reconstitution proceeds toward the 5' terminus of the RNA until it is fully encapsidated. Encapsidation of the 3' distal portion of the RNA apparently occurs later and in a direction opposite to that of the encapsidation of the 5' distal portion.
