Genome Studies in Amaranthus cruentus L. and A. hypochondriacus L. Based on Repeatomic and Cytogenetic Data.

ABSTRACT: Amaranthus cruentus L. and Amaranthus hypochondriacus L. are valuable and promising food crops for multi-purpose use that are distributed worldwide in temperate, subtropical, and tropical zones. However, their karyotypes and genomic relationships still remain insufficiently studied. For the first time, a comparative repeatome analysis of A. cruentus and A. hypochondriacus was performed based on the available NGS data; bioinformatic analyses using RepeatExplorer/TAREAN pipelines; and chromosome FISH mapping of 45S rDNA, 5S rDNA, and the most abundant satellite DNAs. In the repeatomes of these species, interspecific variations in the amount of Ty3/Gypsy and Ty1/Copia retroelements, DNA transposons, ribosomal, and satellite DNA were detected. In the repeatomes of b
