A reference genome for Isoetes and the evolution of aquatic CAM photosynthesis.

Since the publication of the first plant genome Arabidopsis thaliana in 2000, reference genomes for all major green lineages have been published, except for a few orphan clades such as Isoetes (Isoetales). Isoetes is one of the three lycophyte lineages, together with Selaginellales (Selaginella) and Lycopodiales (e.g. Lycopodium). Isoetes harbors an array of unique morphological and developmental characteristics, making it an important link to understand major transitions during land plant evolution. In addition, despite having an aquatic lifestyle, some Isoetes species can carry out crassulacean acid metabolism (CAM) photosynthesis, which is usually associated with xeric adaptation. Here we will present the genome of Isoetes taiwanensis sequenced using the Oxford Nanopore technology. We will also report on the ongoing research using I. taiwanensis as a model to study the gene regulatory network of aquatic CAM photosynthesis.
