Well-supported phylogenies using largest subsets of core-genes by discrete particle swarm optimization [PDF]

open access: yesarXiv, 2017
The number of complete chloroplastic genomes increases day after day, making it possible to rethink plants phylogeny at the biomolecular era. Given a set of close plants sharing in the order of one hundred of core chloroplastic genes, this article focuses on how to extract the largest subset of sequences in order to obtain the most supported species ...

Extensive and widespread homologies between mitochondrial DNA and chloroplast DNA in plants.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1984
We used hybridization techniques to demonstrate that numerous sequence homologies exist between cloned mung bean and spinach chloroplast DNA (ctDNA) restriction fragments and mtDNAs from corn, mung bean, spinach, and pea.

High Spatio-Temporal-Resolution Detection of Chlorophyll Fluorescence Dynamics from a Single Chloroplast with Confocal Imaging Fluorometer [PDF]

open access: yesarXiv, 2016
Chlorophyll fluorescence (CF) is a key indicator to study plant physiology or photosynthesis efficiency. Conventionally, CF is characterized by fluorometers, which only allows ensemble measurement through wide-field detection. For imaging fluorometers, the typical spatial and temporal resolutions are on the order of millimeter and second, far from ...

Use of the fluorochrome 4'6-diamidino-2-phenylindole in genetic and developmental studies of chloroplast DNA

open access: yesJournal of Cell Biology, 1979
Use of the DNA-specific fluorochrome 4'6-diamidino-2-phenylindole (DAPI) makes it possible to examine in situ the structure of chloroplast DNA (chDNA) with the fluorescence microscope.

Nuclear DNA endoreplication and plastid index in mesophyll of some dicotyledonous species

open access: yesActa Societatis Botanicorum Poloniae, 2014
Cytophotometric studies of nuclear DNA content after Feulgen procedure indicate that in mesophyll of all the seven studied species the highest nuclear DNA endoreplication level occurs in II or III leaf and it varies for particular species. No differences

Relation between Gene Content and Taxonomy in Chloroplasts [PDF]

open access: yesarXiv, 2016
The aim of this study is to investigate the relation that can be found between the phylogeny of a large set of complete chloroplast genomes, and the evolution of gene content inside these sequences. Core and pan genomes have been computed on \textit{de novo} annotation of these 845 genomes, the former being used for producing well-supported ...

ASAP: Amplification, sequencing & annotation of plastomes

open access: yesBMC Genomics, 2005
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 ...
