In collaboration with the Dan Voytas group and colleagues, the Ty retrotransposons were given systematic names in the format "YX(L/R)(W/C)Ty?-n", where "X" is the letter that stands for the chromosome number, "L" or "R" is used to signify the left or right arm of the chromosome, "W" or "C" is used to show whether the element starts on the Watson or Crick strand, "Ty?" indicates which type of Ty it is, and "n" is a unique number for that type of element on the chromosome. For an example, see YJRWTy1-1. The Ty LTRs are also named. The format is "YX(L/R)(W/C)element-n." The only difference is that the type of Ty LTR ("element") is indicated by a Greek letter. Ty1 and Ty2 LTRs are indicated "delta," Ty3 TLRs are "sigma," Ty4 LTRs are "tau," and Ty5 LTRs are "omega." Two examples can be seen in YFLWdelta2 and YORWtau3.
