GameXPeptide synergistically enhances the control efficiency of Metarhizium anisopliae by inhibiting cotton aphid immunity

open access: yesNew Plant Protection, Volume 3, Issue 1, March 2026.
In this research, GXP serves as a potent synergist for Metarhizium anisopliae in controlling cotton aphids. Its synergistic effect is achieved through two key mechanisms: first, by downregulating melanization protease 1 expression to inhibit phenoloxidase activity, thereby suppressing melanization; second, by reducing hypoxanthine levels, which ...

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

open access: yesThe FEBS Journal, Volume 293, Issue 6, Page 1801-1817, March 2026.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

open access: yesMolecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

A Modular Biosensor Platform for the Detection of Plastic Monomers and the Engineering of Promiscuous Amidases Toward Challenging Substrates

open access: yesAdvanced Science, Volume 13, Issue 6, 30 January 2026.
A luciferase is used as biosensor for aldehydes, produced enzymatically from different monomeric building blocks of plastics like polyurethanes (PUs). The screening platform is used to monitor esterase, amidase, and urethanase activity and to guide the selection of enzyme variants with improved hydrolytic activities toward difficult to hydrolyze ...

Engineering Conditional Transgene Expression in Nicotiana benthamiana

open access: yesPlant Biotechnology Journal, Volume 24, Issue 1, Page 18-30, January 2026.
ABSTRACT Nicotiana benthamiana has emerged as a premier plant biofactory for recombinant protein and metabolite production due to its high metabolic versatility, ease of cultivation and permissiveness to transient expression vectors. However, challenges such as transgene silencing, low yields and metabolic toxicity limit its scalability. Synthetic gene
