Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Oikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Gene turnover in the common ancestor of all C4 grasses

PLANTS, 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

An analysis of Echinacea chloroplast genomes: Implications for future botanical identification

Scientific Reports, 2017
Echinacea is a common botanical used in dietary supplements, primarily to treat upper respiratory tract infections and to support immune function. There are currently thought to be nine species in the genus Echinacea. Due to very low molecular divergence

Inheritance of chloroplast DNA inPopulus

Theoretical and Applied Genetics, 1991
Restriction fragment length polymorphisms (RFLPs) were used as markers to determine the transmission of chloroplast DNA (cpDNA) in poplar crosses. The plant material studied included individual trees ofPopulus trichocarpa, P. maximowiczii xtrichocarpa, P. maximowiczii xnigra, and offspring from controlled crosses between these trees.

The need for manual curation of the cotton proteome leads to a solution primed for undergraduate involvement

PLANTS, PEOPLE, PLANET, EarlyView.
Cotton is a global crop cultivated worldwide, yet a significant portion of the cotton genome remains functionally unannotated. Attempts have been made to automate this annotation but have been unable to completely bridge the gap. Human curation is still needed for accurate interpretations and predictions to be made.

Functional specialization amongst the Arabidopsis Toc159 family of chloroplast protein import receptors [PDF]

, 2004
The initial stages of preprotein import into chloroplasts are mediated by the receptor GTPase Toc159. In Arabidopsis thaliana, Toc159 is encoded by a small gene family: atTOC159, atTOC132, atTOC120, and atTOC90.

Plant species are more important to bacterial community composition than seeding ratio in a pea‐canola intercropping system

PLANTS, PEOPLE, PLANET, EarlyView.
Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]

, 2002
Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

Pest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...
