An Expanded Ribosomal Phylogeny of Cyanobacteria Supports a Deep Placement of Plastids

Frontiers in Microbiology, 2019
The phylum Cyanobacteria includes free-living bacteria and plastids, the descendants of cyanobacteria that were engulfed by the ancestral lineage of the major photosynthetic eukaryotic group Archaeplastida. Endosymbiotic events that followed this primary

Genomic perspectives on the birth and spread of plastids

Proceedings of the National Academy of Sciences of the United States of America, 2015
The endosymbiotic origin of plastids from cyanobacteria was a landmark event in the history of eukaryotic life. Subsequent to the evolution of primary plastids, photosynthesis spread from red and green algae to unrelated eukaryotes by secondary and ...

Plastids of Marine Phytoplankton Produce Bioactive Pigments and Lipids

Marine Drugs, 2013
Phytoplankton is acknowledged to be a very diverse source of bioactive molecules. These compounds play physiological roles that allow cells to deal with changes of the environmental constrains.

Global metagenomics reveals plastid diversity and unexplored algal lineages [PDF]

Nature Communications
Photosynthetic organelles in eukaryotes originated through primary endosymbiosis with a cyanobacterium, an event that profoundly shaped the evolutionary landscape of the eukaryotic tree of life.

A molecular timescale for eukaryote evolution with implications for the origin of red algal-derived plastids

Nature Communications, 2021
In modern oceans, eukaryotic phytoplankton is dominated by lineages with red algal-derived plastids such as diatoms, dinoflagellates, and coccolithophores. Despite the ecological importance of these groups and many others representing a huge diversity of

Overexpression of PSY1 increases fruit skin and flesh carotenoid content and reveals associated transcription factors in apple (Malus × domestica)

Frontiers in Plant Science, 2022
Knowledge of the transcriptional regulation of the carotenoid metabolic pathway is still emerging and here, we have misexpressed a key biosynthetic gene in apple to highlight potential transcriptional regulators of this pathway. We overexpressed phytoene

Eukaryotes arose after genetic recombination [PDF]

Archive of Oncology, 2006
Division of ancestral prokaryotic pragenome into two circular double-stranded DNA molecules by genetic recombination, is a base for future separate evolution of nuclear and mitochondrial gene compartment.

Rice carotenoid biofortification and yield improvement conferred by endosperm-specific overexpression of OsGLK1

Frontiers in Plant Science, 2022
Carotenoids, indispensable isoprenoid phytonutrients, are synthesized in plastids and are known to be deficient in rice endosperm. Many studies, involving transgenic manipulations of carotenoid biosynthetic genes, have been performed to obtain carotenoid-

Eco-Evolutionary Perspectives on Mixoplankton

Frontiers in Marine Science, 2021
Mixotrophy, i.e., the capability of both phototrophy and phagotrophy within a single organism, is a prominent trophic mode in aquatic ecosystems. Mixotrophic strategies can be highly advantageous when feeding or photosynthesis alone does not sustain ...
