Brown algae (Phaeophyceae) are a eukaryotic lineage that has been evolving independently from animals and plants for more than a billion years. Brown algae constitute the third most complex eukaryotic multicellular lineage, displaying a wide variety of complex morphologies in both the haploid and diploid phases of their life cycle, thus representing a unique model to study the universality or uniqueness of biological processes throughout the tree of life.
Not only did brown algae evolved complex multicellularity, they also evolved a sex-determination system based on UV chromosomes. Besides determining sex, the UV chromosomes in brown algae display interesting evolutionary dynamics that distinguish them from the autosomes.
I'm currently studying the evolution of brown algae using phylogenetics and comparative genomics to understand the emergence of complexity in this group, as well as the evolution of their sex chromosomes and how they influence the emergence of novel genomic elements.
