Abstract Lycophytes and seed plants constitute the typical vascular plants. have been thought to no paleo-polyploidization although event is known be critical for fast expansion of Here, genomic analyses including homologous gene dot plot analysis detected multiple events, with one occurring approximately 13–15 million years ago (MYA) another about 125–142 MYA, during evolution genome Selaginella moellendorffii, a model lycophyte. In addition, comparative reconstructed ancestral genomes...
Abstract Seed plants and lycophytes constitute the extant vascular plants. As a model lycophyte, Selaginalla moellendroffii was deciphered its genome, previously proposed to have avoided polyploidies, as key events contributing origination fast expansion of seed Here, using gold-standard streamline recently deconvolute complex genomes, we reanalyzed S. genome. To our surprise, found clear evidence multiple paleo-polyploidies, with one being recent (~ 13-15 millions years ago or Mya), another...
