Background The cactus family (Cactaceae) has been reported to have evolved a minimal photosynthetic plastome size, with the loss of inverted-repeat (IR) regions and NDH gene suites.

Evolutionary Stasis in Cycad Plastomes and the First Case of Plastome GC-Biased Gene Conversion [PDF]
In angiosperms, gene conversion has been known to reduce the mutational load of plastid genomes (the plastomes). Particularly, more frequent gene conversions in inverted repeat (IR) than in single copy (SC) regions result in contrasting substitution rates between these two regions.

Gene Loss and Evolution of the Plastome [PDF]
AbstractChloroplasts are unique organelles within the plant cells and are responsible for sustaining life forms on the earth due to their ability to conduct photosynthesis. Multiple functional genes within the chloroplast are responsible for a variety of metabolic processes that occur in the chloroplast.

ASAP: Amplification, sequencing & annotation of plastomes [PDF]
Abstract Background Availability of DNA sequence information is vital for pursuing structural, functional and comparative genomics studies in plastids. Traditionally, the first step in mining the valuable information within a chloroplast genome requires sequencing a chloroplast plasmid library or BAC clones.

Plastome Phylogenomics of Aucuba (Garryaceae) [PDF]
Aucuba (Garryaceae), which includes approximately ten evergreen woody species, is a genus endemic to East Asia. Their striking morphological features give Aucuba species remarkable ornamental value. Owing to high levels of morphological divergence and plasticity, species definitions of Aucuba remain perplexing and problematic.

Plastome Diversity and Phylogenomic Relationships in Asteraceae [PDF]
Plastid genomes are in general highly conserved given their slow evolutionary rate, and thus large changes in their structure are unusual. However, when specific rearrangements are present, they are often phylogenetically informative. Asteraceae is a highly diverse family whose evolution is long driven by polyploidy (up to 48x) and hybridization, both ...

Genome-scale angiosperm phylogenies based on nuclear, plastome, and mitochondrial datasets.
Angiosperms dominate the Earth's ecosystems and provide most of the basic necessities for human life. The major angiosperm clades comprise 64 orders, as recognized by the APG IV classification.

New insights into the plastome evolution of Lauraceae using herbariomics
Background The family Lauraceae possesses ca. 50 genera and 2,500–3,000 species that are distributed in the pantropics. Only half of the genera of the family were represented in previously published plastome phylogenies because of the difficulty of ...
