Phylogeny of Prokaryotes and Chloroplasts Revealed by a Simple Composition Approach on All Protein Sequences from Complete Genomes Without Sequence Alignment [PDF]

open access: yes, 2005
The complete genomes of living organisms have provided much information on their phylogenetic relationships. Similarly, the complete genomes of chloroplasts have helped to resolve the evolution of this organelle in photosynthetic eukaryotes.

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

open access: yes, 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 ...

Inferring the evolutionary mechanism of the chloroplast genome size by comparing whole-chloroplast genome sequences in seed plants

open access: yesScientific Reports, 2017
The chloroplast genome originated from photosynthetic organisms and has retained the core genes that mainly encode components of photosynthesis. However, the causes of variations in chloroplast genome size in seed plants have only been thoroughly ...

The complete chloroplast genome sequence of cultivated peach (Prunus persica var. nectarina cv. ‘Rui Guang 18’)

open access: yesMitochondrial DNA. Part B. Resources, 2021
Peach (Prunus persica) is one of the most important economic fruit crops in the current society. In this study, we reported the complete chloroplast genome sequence of peach cultivar ‘Rui Guang 18’ (Prunus persica var. nectarina cv. ‘Rui Guang 18’) using
