Adrián Reyes-Prieto

Adrián Reyes-Prieto is interested in understanding the molecular and cellular mechanisms underlying the establishment of endosymbiotic associations. He studies the origin and evolution of photosynthetic organelles in microbial eukaryotes. In recent years, comparative genomic studies from different photosynthetic eukaryotes and their non-photosynthetic relatives have yielded insights on critical processes involved in the transformation of free-living cells into obligated endosymbionts, such as gene transference, genome reduction mechanisms, and potential cases of multiple and subsequent endosymbioses.

Plantae are extant algae bearing plastids surrounded by two membranes, and include Glaucophytes, red algae and Viridiplantae (green algae and land plants). It has been hypothesized that Plantae (also called Archaeplastida) are descended from a unique common ancestor that recruited endosymbiotic cyanobacteria more than a billion years in the past. Testing this hypothesis of common origin of Plantae is essential to elucidating the emergence of the first photosynthetic eukaryotes. One avenue to study this hypothesis is through comparative studies of the genetic and protein repertoires from different Plantae lineages. Green algae and land plants have been thoroughly studied in this respect, but much work remains for red algae and Glaucophytes.
