Assessment of Small‐Scale Laboratory Rearing Systems for Frankliniella occidentalis (Western Flower Thrips) Using a Single Female

Journal of Applied Entomology, EarlyView.
ABSTRACT Reliable laboratory rearing of Frankliniella occidentalis is critical for experimental consistency in entomological research. This study validates and optimises three small‐scale rearing systems initiated from a single female thrips using various organic fruits, flowers and pollen as feed, along with moist cotton, blotting paper and ...

ZmMS1 coordinates ROS homeostasis, lipid allocation, and male fertility for maize breeding applications

Journal of Integrative Plant Biology, EarlyView.
The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.
