The polyploid Leymus species have the Ns nuclear genomes evolved from Psathyrostachys and the Xm nuclear genomes from unknown origins. Currently, little is known about the cytoplasmic genomes of Leymus, and the species of Psathyrostachys that transferred the Ns genome to Leymus remain elusive. To determine the origins of the plastid and nuclear genome for Leymus species, sequences of two chloroplast genes, rpoA and rbcL, and partial sequences of the nuclear gene DMC1 of 15 Leymus species were… CONTINUE READING
