Structural and Stability Analysis of de Novo Designed Proteins Incorporating a Plant Self‐Incompatibility Motif

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Artificial protein design enables the creation of stable scaffolds beyond those evolved in nature. Incorporation of native functional motifs into de novo scaffolds provides a promising strategy to mimic natural interactions while altering structural frameworks.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

UV mutagenesis‐enhanced Streptomyces nogalater produces a novel streptothricin‐like compound with strong activity against cabbage soft rot

open access: yesPest Management Science, EarlyView.
UV mutagenesis of Streptomyces sp. KRA0514‐6 yielded HL‐3, a novel streptothricin‐like compound (C17H29N7O8) with N‐methylglycine replacing β‐lysine, achieving 100% cabbage soft rot control at >1 ppm concentration. Abstract BACKGROUND A total of 1000 soil‐derived actinomycetes were isolated and screened for antibacterial activity against Pectobacterium
