Calcium signaling in plant defense

open access: yesNew Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

open access: yesNew Plant Protection, EarlyView.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

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
