Cold acclimation of the thermoacidophilic red alga Galdieria sulphuraria - changes in gene expression and involvement of horizontally acquired genes

(Submitter supplied) Purpose: We aimed at i) obtaining insight into how a thermophile organism reacts to cold stress, and ii) evaluating the impact of HGT candidates on the acclimation process to temperature decrease. Methods: The experimental design followed a temperature shift timeline: after two weeks of cultivation at 42°C, constant illumination (90 μE) and constant shaking (160 rpm) in photoautotrophic conditions the first sampling took place (Hot_T48_1) and the cultures of G.sulphuraria were swiftly moved to 28°C ( = cold temperature). more...

Selection for transcript diversity in the extremophile Galdieria sulphuraria results in retention of the splicing machinery

(Submitter supplied) Purpose: Red algae show two putative phases of massive genome reduction. RNA-splicing represents an important form of post-transcriptional regulation in eukaryotes. This process generates increased transcriptome and proteome diversity via alternative splicing that can maximize the DNA-encoded genetic diversity embedded within genomes. Why would Spliceosomal Machinery genes and a relatively more complex intron-exon structure be preserved in the compact Galdieria genome? The answer may lie in the fact that RNA-splicing represents an important form of post-transcriptional regulation in eukaryotes. more...
