Pineapple (Ananas comosus) is a tropical plant. It belongs to the Poales group and split off early in its evolution. Thanks to whole-genome sequencing, scientists can now study the pineapple and related plants in more detail. Research using both mitochondrial and nuclear DNA shows that all Ananas species come from a single common ancestor. It also helps place pineapple clearly within the Bromeliaceae family. This study looks at how comparing genomes helps us understand how important traits in pineapple evolved. The results show that the pineapple genome has not had a recent whole-genome duplication. But other changes, like sudden increases in transposons and repeated copies of certain genes, have changed many gene families. These discoveries show that having full genome data has made pineapple a useful plant for studying how monocots have evolved over time.
