Evolutionary insights into bilin biosynthesis: Functional characterization of pre‐PcyA enzymes

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Biosynthesis of the linear tetrapyrrole phycocyanobilin (PCB) by the ferredoxin‐dependent bilin reductase (FDBR) PcyA is essential for light‐harvesting and regulatory processes in diverse photosynthetic organisms, yet its evolutionary origins are not fully understood. PcyA evolved from pre‐PcyA proteins found in diverse bacteria.

A High‐Resolution Method Using Individual Females to Assess the Competitiveness of Sterile Drosophila suzukii Males Under Semi‐Controlled Conditions

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 9, Page 1011-1021, September 2026.
A high‐resolution, novel method to assess the sexual competitiveness of sterile mass‐reared Drosophila suzukii males is calibrated and illustrated using different laboratory and wild type strains. Isolation of individual females after semi‐controlled cage competition tests and subsequent observation of their progeny showed that sterile males from two ...
