Reverse genetics in the Arabidopsis chloroplast genome identifies rps16 as a transcribed pseudogene

open access: yesThe Plant Journal, Volume 122, Issue 3, May 2025.
SUMMARY The plastid (chloroplast) genomes of seed plants contain a conserved set of ribosomal protein genes. The rps16 gene represents an exception: It has been lost from the plastid genomes of gymnosperms and several lineages of angiosperms, and may have undergone pseudogenization in a few other lineages, including members of the Brassicaceae family ...

In‐Depth Analysis of the Complex Interactions Induced by Nanolayered Additives in PHBV Nanocomposites

open access: yesMacromolecular Materials and Engineering, Volume 309, Issue 7, July 2024.
New poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV)‐based nanocomposites are developed by the addition of two nanolayered additives, cloisite 20A and calcined hydrotalcite, to improve the thermal and mechanical properties of the biopolymer matrix. The characterization of the nanocomposites proves the enhancement in PHBV behavior.

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity

open access: yesFortschritte der Physik, Volume 72, Issue 4, April 2024.
Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar
