Abstract:
Rhodopseudomonas palustris is renowned for its metabolic versatility, supported by a genome that contains pathways for numerous processes. In a recent study, Oda et al. (Appl Environ Microbiol 91:e02056-24, 2025, https://doi.org/10.1128/aem.02056-24) examine R. palustris DSM127, a strain with a dramatically reduced gene inventory, to study how environmental pressures have influenced gene loss. Missing more than a quarter of its genome reduces its versatility. However, it may improve its efficiency under the conditions in which it still thrives, enhancing its aptitude as a chassis for biotechnology.
