Rethinking plastid evolution [PDF]

EMBO reports, 2010
How easy is it to acquire an organelle? How easy is it to lose one? These questions underpin the current debate about the evolution of the plastid—that is, chloroplast—the organelle of photosynthesis in eukaryotic cells. The origin of the plastid has been traced to an endosymbiosis between a eukaryotic host cell and a cyanobacterial symbiont, the ...

Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]

, 2016
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...

Plastid proteome prediction for diatoms and other algae with secondary plastids of the red lineage [PDF]

, 2014
The plastids of ecologically and economically important algae from phyla such as stramenopiles, dinoflagellates and cryptophytes were acquired via a secondary endosymbiosis and are surrounded by three or four membranes.

NCP activates chloroplast transcription by controlling phytochrome-dependent dual nuclear and plastidial switches. [PDF]

, 2019
Phytochromes initiate chloroplast biogenesis by activating genes encoding the photosynthetic apparatus, including photosynthesis-associated plastid-encoded genes (PhAPGs).

The bRPS6-Family Protein RFC3 Prevents Interference by the Splicing Factor CFM3b during Plastid rRNA Biogenesis in Arabidopsis thaliana

Plants, 2020
Plastid ribosome biogenesis is important for plant growth and development. REGULATOR OF FATTY ACID COMPOSITION3 (RFC3) is a member of the bacterial ribosomal protein S6 family and is important for lateral root development. rfc3-2 dramatically reduces the

Organellar Evolution: A Path from Benefit to Dependence

Microorganisms, 2022
Eukaryotic organelles supposedly evolved from their bacterial ancestors because of their benefits to host cells. However, organelles are quite often retained, even when the beneficial metabolic pathway is lost, due to something other than the original ...

The use of chloroplast genome sequences to solve phylogenetic incongruences in Polystachya Hook (Orchidaceae Juss) [PDF]

, 2018
Background: Current evidence suggests that for more robust estimates of species tree and divergence times, several unlinked genes are required. However, most phylogenetic trees for non-model organisms are based on single sequences or just a few regions ...

RNA-sequencing analysis of the msl2 msl3, crl, and ggps1 mutants indicates that diverse sources of plastid dysfunction do not alter leaf morphology through a common signaling pathway

Frontiers in Plant Science, 2015
Determining whether individual genes function in the same or in different pathways is an important aspect of genetic analysis. As an alternative to the construction of double mutants, we used contemporary expression profiling methods to perform pathway ...

Phylogenomics and Biogeography of the Eastern Asian–Eastern North American Disjunct Genus Hylodesmum (Fabaceae)

Biological Diversity, EarlyView.
Integrating data from plastid genomes, nrDNA, and 353 low‐copy nuclear genes, this study establishes a robust phylogenetic framework for Hylodesmum. This framework supports a taxonomic revision recognizing 18 species and reveals a complex pattern of bidirectional EA–ENA dispersal, with mammals as a plausible dispersal agent. ABSTRACT Phylogenomics with

Site-directed mutagenesis from Arg195 to His of a microalgal chloroplastidial glycerol-3-phosphate acyltransferase causes an increase in phospholipid levels in yeast

Frontiers in Plant Science, 2016
To analyze the contribution of glycerol-3-phosphate acyltransferase (GPAT) to the first acylation of glycerol-3-phosphate (G-3-P), the present study focused on a functional analysis of the GPAT gene from Lobosphaera incisa (designated as LiGPAT) and the ...
