Prevalent pH Controls the Capacity of to Use Ammonia and Nitrate as a Nitrogen Source.

is a polyextremophilic alga capable of diverse metabolic processes. Ammonia is widely used in culture media typical of laboratory growth. Recent reports that this species can grow on wastes promote the concept that might have biotechnological utility.

A Spotlight on Rad52 in Cyanidiophytina (Rhodophyta): A Relic in Algal Heritage.

The RADiation sensitive52 (RAD52) protein catalyzes the pairing between two homologous DNA sequences' double-strand break repair and meiotic recombination, mediating RAD51 loading onto single-stranded DNA ends, and initiating homologous recombination and catalyzing DNA annealing. This article reports the characterization of RAD52 homologs in the thermo-acidophilic Cyanidiophyceae whose genomes have undergone extensive sequencing. Database mining, phylogenetic inference, prediction of protein structure and evaluation of gene expression were performed in order to determine the functionality of the RAD52 protein in Cyanidiophyceae.
