Chloroplast DNA codes for transfer RNA

open access: yesNucleic Acids Research, 1976
Transfer RNA's were isolated from Euglena gracilis. Chloroplast cistrons for tRNA were quantitated by hybridizing tRNA to ct DNA. Species of tRNA hybridizing to ct DNA were partially purified by hybridization-chromatography. The tRNA's hybridizing to ct DNA and nuclear DNA appear to be different.

Transcriptomic stress responses in Vaccinium spp. F1 hybrids: Implications for temperature‐resilient cranberry breeding using a crop wild relative

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate extremes threaten the sustainability of cranberry production, a culturally and economically important North American crop. This study demonstrates that wild cranberries (Vaccinium oxycoccos) harbor genetic variation that may enhance cold stress resilience when introduced into cultivated cranberry through hybridization.

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Characterization of the complete chloroplast genome of Chenopodium sp. (Caryophyllales: Chenopodiaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
In this study, the complete chloroplast genome of Chenopodium sp. were sequenced and annotated. The complete chloroplast genome of Chenopodium sp. was composed of circular DNA molecules with a total length of 152,068 bp.

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

open access: yesPest Management Science, EarlyView.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Comparative analysis of chloroplast and mitochondrial genomes of sweet potato provides evidence of gene transfer

open access: yesScientific Reports
The increasing number of plant mitochondrial DNA genomes (mtDNA) sequenced reveals the extent of transfer from both chloroplast DNA genomes (cpDNA) and nuclear DNA genomes (nDNA).

Phylogenetic analysis and evolutionary trend inference of chloroplast genomes in Elaeagnaceae

open access: yesXibei zhiwu xuebao
[Objective] The purpose of the research was to explore the evolutionary pattern of chloroplast genome in Elaeagnaceae, and to provide a basis for species identification and resource exploitation of Elaeagnaceae.

Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

open access: yesPest Management Science, EarlyView.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.
