Heterologous expression of oxygen binding proteins increases O2 diffusion depth in snowflake yeast. (A) Schematic showing construction of snowflake yeast strains expressing myoglobin or myohemerythrin integrated at the HO locus. (B) Quantification of oxygen diffusion depth using the mitochondrial MitoLoc reporter in snowflake yeast clusters expressing oxygen binding proteins or wildtype controls under oxygen limitation. Myohemerythrin and myoglobin expression significantly increased oxygen diffusion depth, but only in the low oxygen environment. Data are mean ± s.d. (C) Representative fluorescence micrographs of MitoLoc showing increased depth of oxygen penetration (yellow) in clusters expressing myoglobin (right) compared to a wildtype control (left) under low oxygen. -- biorxiv.org/

Examining The Role Of Oxygen-binding Proteins On The Early Eevolution Of Multicellularity

by Keith CowingFebruary 2, 2024February 2, 2024

Oxygen availability is a key factor in the evolution of multicellularity, as larger and more sophisticated organisms often require mechanisms allowing efficient oxygen delivery to their tissues. One such mechanism […]
