Genome size estimation of false daisy, cheek weed, pot marigold and marigold

We report the genome size estimated using flow cytometry for four closely related species, including false daisy (Eclipta prostrate), cheek weed (Ageratum conyzoides), pot marigold (Calendula officinalis), and marigold (Tagetes erecta) belonging to Asteraceae family. The detected genome size for false daisy, cheek weed, pot marigold, and marigold was, 2.435, 3.266, 3.413, and 1.897, Gbp, respectively, while their respective 2C DNA content was 2.5, 3.3, 3.5, and 1.9, pg. The information on genome size presented here will be useful for understanding genomic evolution and will also clear the way for additional genomic research in these species.
