Gene Loss and Evolution of the Plastome [PDF]
Genes, 2019 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]
BMC Genomics, 2005 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.

Evolutionary Stasis in Cycad Plastomes and the First Case of Plastome GC-Biased Gene Conversion [PDF]
Genome Biology and Evolution, 2015 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.

Plastome Phylogenomics of Aucuba (Garryaceae) [PDF]
Frontiers in Genetics, 2022 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]
Plants, 2021 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 ...

Comparative analysis of Dendrobium plastomes and utility of plastomic mutational hotspots [PDF]
Scientific Reports, 2017 AbstractDendrobium is one of the largest genera in Orchidaceae, comprising about 800–1500 species mainly distributed in tropical Asia, Australasia, and Australia. There are 74 species and two varieties of this genus in China. Because of their ornamental and commercial value, Dendrobium orchids have been studied at low taxonomic levels.

Plastome Evolution in Hemiparasitic Mistletoes [PDF]
Genome Biology and Evolution, 2015 Santalales is an order of plants consisting almost entirely of parasites. Some, such as Osyris, are facultative root parasites whereas others, such as Viscum, are obligate stem parasitic mistletoes. Here, we report the complete plastome sequences of one species of Osyris and three species of Viscum, and we investigate the evolutionary aspects of ...

Systematics and Plastome Evolution in Schizaeaceae
Frontiers in Plant Science, 2022 While the family Schizaeaceae (Schizaeales) represents only about 0.4% of the extant fern species diversity, it differs from other ferns greatly in gross morphologies, niche preferences, and life histories. One of the most notable features in this family is its mycoheterotrophic life style in the gametophytic stage, which appears to be associated with ...

Plastome variation and phylogeny of Taxillus (Loranthaceae)
PLOS ONE, 2021 Several molecular phylogenetic studies of the mistletoe family Loranthaceae have been published such that now the general pattern of relationships among the genera and their biogeographic histories are understood. Less is known about species relationships in the larger (> 10 species) genera.

BMC Plant Biology, 2023 AbstractBackgroundThe 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. However, there are very limited genomic data on the family, especially Cereoideae, the largest subfamily of cacti.ResultsIn the present study, we assembled and ...
