Energy metabolism and adaptation to hypoxia in the non-photosynthetic green alga Leontynka.

ABSTRACT:

Background

Leontynka is a non-photosynthetic lineage of the order Chlamydomonadales (Chlorophyta). Although many Chlamydomonadales members encode components of the anaerobic energy metabolism, studies focused on Chlamydomonadales algae thriving in hypoxia and not prospering in oxic conditions are missing. Using a combination of experimental approaches, comparative genomics, and advanced in silico protein localization analyses, we employed Leontynka as a model to investigate the evolution of anaerobiosis in Chlamydomonadales.

Results

Leontynka spp. accumulate a wide range of storage forms, enabling them to cope with nutritional stresses. Their mitochondria contain well-developed cristae mediating a conventional aerobic energy metabolism. Moreover, colocalization of a Raman si
