Distribution and characteristic features of individual groups of Ty3/gypsy (a) and Ty1/copia (b) retrotransposons in plants. Question mark in the “PBS type” column denotes similarity to 3′ end of undetermined types of tRNA. PBSs complementary to half-molecule tRNA are designated with a “1/2” prefix before the tRNA type. PBSs exploiting self-priming are labeled as “self”. Prevailing organization of the polyprotein coding ORFs was not determined (labeled ND) in some groups due to random stop codon and frameshift mutations in most elements. All schemes of representative elements are to scale
