Analysis of horizontal genetic transfer in red algae in the post-genomics age [PDF]
, 2013 The recently published genome of the unicellular red alga revealed a gene-rich, intron-poor species, which is surprising for a free-living mesophile. Of the 8,355 predicted protein-coding regions, up to 773 (9.3%) were implicated in horizontal genetic ...

Integrative Zoology, EarlyView.Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

The metabolite transporters of the plastid envelope: an update.
Frontiers in Plant Science, 2011 The engulfment of a photoautotrophic cyanobacterium by a primitive mitochondria-bearing eukaryote traces back to more than 1.2 billion years ago. This single endosymbiotic event not only provided the early protoalga with the metabolic capacity to perform

A potential cyanobacterial ancestor of Viridiplantae chloroplasts [PDF]
, 2011 The theory envisaging the origin of plastids from endosymbiotic cyanobacteria is well-established but it is difficult to explain the evolution (spread) of plastids in phylogenetically diverse plant groups.

The gateway to chloroplast: re-defining the function of chloroplast receptor proteins [PDF]
, 2012 Chloroplast biogenesis often requires a tight orchestration between gene expression (both plastidial and nuclear) and translocation of similar to 3000 nuclear-encoded proteins into the organelle.

The FEBS Journal, EarlyView.The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

How Mitochondrial Signaling Games May Shape and Stabilize the Nuclear-Mitochondrial Symbiosis
BiologyThe eukaryotic lineage has enjoyed a long-term “stable” mutualism between nucleus and mitochondrion, since mitochondrial endosymbiosis began about 2 billion years ago.

Biological invasions and endosymbiosis in Arthropods, a case study:Bemisia tabaci : S1403TH01 Invasive Species and Quarantine [PDF]
, 2012 Biological invasions are more and more frequent worldwide and understanding this process is a big issue. Invasive success depends on several traits permitting local adaptation.

Integration of plastids with their hosts: Lessons learned from dinoflagellates. [PDF]
, 2015 After their endosymbiotic acquisition, plastids become intimately connected with the biology of their host. For example, genes essential for plastid function may be relocated from the genomes of plastids to the host nucleus, and pathways may evolve ...

Journal of Integrative Plant Biology, EarlyView.Under heat stress, GENOMES UNCOUPLED1 (GUN1) is crucial for the formation of functional chloroplasts in seedlings under heat stress. Without GUN1, chloroplast development fails and seedlings fail to turn green. Therefore, GUN1 helps relay heat‐related cues to maintain chloroplast biogenesis and support thermotolerance during early growth.
