Structures of the Copia-Like Retrotransposon Sal-T1 and the DNA Transposon Sal-PIF in Yellow Mustard.

(A) Structure of the Copia-like retrotransposon Sal-T1 inserted in the 5′ UTR of FAE1 alleles E² and E³. Sal-T1 comprised a PBS, a PPT, LTRs on each side, and a 2877-bp coding region. The target site duplication sequence is in red font. Sal-T1 was inserted in reverse orientation at position −36 as indicated by a black triangle.

(B) Structure of the DNA transposon Sal-PIF inserted in the coding region of FAE1 allele e. Black triangle, inverted repeats (TIRs); nucleotide sequence of the TIR is in blue font; ORF1, predicted coding region from position 242 to 1354; ORF2, predicted coding region from 1661 to 2812; putative N2, N3, and C1 catalytic domains are indicated by a black box; amino acid sequences of the catalytic domains of maize PIF and Sal-PIF are shown.
