Biosignatures Associated with Freshwater Microbialites
Life, 2020 Freshwater microbialites (i.e., lithifying microbial mats) are quite rare in northern latitudes of the North American continent, with two lakes (Pavilion and Kelly Lakes) of southeastern BC containing a morphological variety of such structures.

Anoxygenic photoautotrophy driven by humus and microplastics in a photosynthetic bacterium. [PDF]
ISME CommunAbstract Humus and microplastics are recalcitrant organics in soils and aquatic systems, and their role in the geochemical cycling of elements remains elusive. Herein, we have identified a new mechanism by which humus and microplastics participate in anoxic carbon cycling.

Arsenite-dependent photoautotrophy by an Ectothiorhodospira -dominated consortium [PDF]
The ISME Journal, 2008 Abstract Over the past decade numerous lineages of bacteria have been shown to obtain energy for growth through redox transformations of arsenic. However, phototrophic growth using reduced arsenic as an electron donor has not been described. Here we report the light-dependent oxidation of arsenite to arsenate, coupled with autotrophic

Investigation of carbon and energy metabolic mechanism of mixotrophy in Chromochloris zofingiensis
Biotechnology for Biofuels, 2021 Background Mixotrophy can confer a higher growth rate than the sum of photoautotrophy and heterotrophy in many microalgal species. Thus, it has been applied to biodiesel production and wastewater utilization.

The PsbP Protein Is Required for Photosystem II Complex Assembly/Stability and Photoautotrophy in Arabidopsis thaliana [PDF]
Journal of Biological Chemistry, 2007 Interfering RNA was used to suppress the expression of the genes At1g06680 and At2g30790 in Arabidopsis thaliana, which encode the PsbP-1 and PsbP-2 proteins, respectively, of photosystem II (PS II). A phenotypic series of transgenic plants was recovered that expressed intermediate and low amounts of PsbP. Chlorophyll fluorescence induction and Q(A)(-)
