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.

Complete chloroplast genome sequence of Convolvulus arvensis

, 2021
The complete chloroplast genome of Convolvulus arvensis was reconstructed by reference-based assembly using Illumina paired-end data. The assembled plastome is 153,234 base pairs (bp) in length, including a pair of inverted repeat regions (IRs) of 22,662

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Chloroplast alchemy: rewriting the chloroplast genome with high precision

Trends in Plant Science
In the past decade, precise genome editing has transitioned from theory to practical application. Yet, plastid genomes have largely remained impervious to these advances. A recent breakthrough by Mok et al. (2024) demonstrated successful plastid genome editing by developing transgene-free atrazine-resistant arabidopsis (Arabidopsis thaliana) plants.

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

The FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Dating the cyanobacterial ancestor of the chloroplast [PDF]

, 2009
Cyanobacteria have played a pivotal role in the history of life on Earth being the first organism to carry out oxygenic photosynthesis, which changed atmospheric chemistry and allowed the evolution of Eukarya.

Structural insights into θ‐type carbonic anhydrases 3 and 4: Tuning the directionality of CO2 hydration in a diatom

The FEBS Journal, EarlyView.
θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

Species diversity and host plant associations of ambrosia beetles in Southeast Asian forests of Laos and Vietnam revealed by DNA barcoding

Insect Conservation and Diversity, EarlyView.
Integrative DNA barcoding of ambrosia beetles and host plants revealed 27 beetle species across 16 genera and extensive, previously undocumented host plant diversity in Laos and Vietnam. Host specificity varied widely among ambrosia beetles, with Xylosandrus crassiusculus emerging as a dominant generalist associated with 19 host species from 12 plant ...
