An Integrated Strategy Combining Shotgun Metabarcoding With Conventional Methods for Comprehensive Authentication of Food‐Medicine Homologous Species and Fungal Contamination Detection in Yangyin Qingfei Wan

open access: yesFood Safety and Health, EarlyView.
This research confirms shotgun metabarcoding accurately identifies YYQFW components, proving its potential for authenticating complex herbal products. Combined with TLC/HPLC, it offers a regulatory approach for food‐medicine homologous ingredients OTC medicines and aids species identification in processed foods with degraded DNA.

Chloroplast DNA and molecular phylogeny [PDF]

open access: yesBioEssays, 1985
AbstractThe small, relatively constant size and conservative evolution of chloroplast DNA (cpDNA) make it an ideal molecule for tracing the evolutionary history of plant species. At lower taxonomic levels, cpDNA variation is easily and conveniently assayed by comparing restriction patterns and maps, while at higher taxonomic levels, DNA sequencing and ...

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 ...

Soybean (Glycine max L.) Nuclear DNA Contains Four tufA Genes Coding for the Chloroplast-specific Translation Elongation Factor EF-Tu

open access: yesCHIMIA, 1993
The chloroplast tufA gene codes for the translation elongation factor EF- Tu. In algae like e.g. Euglena tufA is part of the chloroplast DNA but in land plants the equivalent gene is transposed to the nuclear DNA.

Use of RNA secondary structure for evolutionary relationships : investigating RNase P and RNase MRP : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, New Zealand [PDF]

open access: yes, 1998
Bioinformatics is applied here to examine whether RNA secondary structure data can reflect distant evolutionary relationships. This is important when there is little confidence in sequence data such as when looking at the evolution of RNase MRP (MRP ...

Bacterial social interactions in synthetic Bacillus consortia enhance plant growth

open access: yesiMeta, EarlyView.
Inoculation with plant growth‐promoting rhizobacteria SQR9 enhances cooperative behaviors and compatibility within the microbial community, promoting plant growth. Building on these interactions, synthetic Bacillus consortia were designed based on phylogenetic relationships and social cooperation, where moderately related consortia exhibited stronger ...

Sequencing of chloroplast genome using whole cellular DNA and Solexa sequencing technology

open access: yesFrontiers in Plant Science, 2012
Sequencing of the chloroplast genome using traditional sequencing methods has been difficult because of its size (>120 kb) and the complicated procedures required to prepare templates.

Intracompartmental and Intercompartmental Transcriptional Networks Coordinate the Expression of Genes for Organellar Functions [PDF]

open access: yes, 2011
Genes for mitochondrial and chloroplast proteins are distributed between the nuclear and organellar genomes. Organelle biogenesis and metabolism, therefore, require appropriate coordination of gene expression in the different compartments to ensure ...
