Testing the Complete Plastome for Species Discrimination, Cryptic Species Discovery and Phylogenetic Resolution in Cephalotaxus (Cephalotaxaceae)

open access: yesFrontiers in Plant Science, 2022
Species of Cephalotaxus have great economic and ecological values. However, the taxonomy and interspecific phylogenetic relationships within the genus have been controversial and remained not fully resolved until now.

Plastome Evolution and Phylogeny of Orchidaceae, With 24 New Sequences

open access: yesFrontiers in Plant Science, 2020
In order to understand the evolution of the orchid plastome, we annotated and compared 124 complete plastomes of Orchidaceae representing all the major lineages in their structures, gene contents, gene rearrangements, and IR contractions/expansions ...

The Plastome and Chloroplast Biogenesis [PDF]

open access: possible, 1988
The most important feature that distinguishes plants from animals is the possession of chloroplasts. These organelles are responsible for the generation of energy and reducing power used to fix CO2. They are also involved in the metabolism of nitrogen, sulphur, lipids, and some plant hormones.

The chicken or the egg? Plastome evolution and an independent loss of the inverted repeat in papilionoid legumes

open access: yesPlant Journal, 2021
The plastid genome (plastome), while surprisingly constant in gene order and content across most photosynthetic angiosperms, exhibits variability in several unrelated lineages.

Plastome phylogenomics of Micromeles (Rosaceae)

Phytotaxa, 2023
Micromeles has been the focus of discussion concerning its relationship with other genera of Sorbus s.l., Maleae, Rosaceae. With the aim to shed light on its circumscription, phylogenetic relationships were investigated using plastomes. The 14 newly sequenced Micromeles plastomes range in size from 159,753 to 160,512 bp, contain 113 unique genes ...

Plastome mutants

Plant Molecular Biology Reporter, 1986
Since the first reports seventy-five years ago on the non-Mendelian inheritance of variegation in plants, chloroplast gene mutations have been useful for genetical and physiological investigations. The mutations have been shown to affect the chloroplast translational apparatus, photosystem I, photosystem II, the cytochrome f/b6 complex, carbon fixation,

Plastid DNA — The Plastome

1980
The development of autotrophic eukaryotic organisms results from a close cooperation between three distinct cellular compartments (using the compartment definition of Schnepf 1966), of nucleus/cytosol, plastids, and mitochondria, each of which contains its own genetic machinery.

When is the Male Plastome eliminated ?

Nature, 1970
PLASTOME mutations result in chloroplast defects which are inherited in a non-Mendelian manner. Because normal and defective chloroplasts can exist in the same cell and be sorted out by somatic segregation, the plastome is considered to be in the chloroplasts themselves, possibly in their DNA. A strictly maternally inherited plastid mutant in Nicotiana
