Effects of fungicides and insecticides applied to spring barley sown on different dates in 1976-79
Factorial experiments in 1976–1979 investigated the effects of sowing date, fungicides (ethirimol seed treatments and tridemorph sprays) and insecticides (phorate applied to the soil, and menazon or dimethoate sprays) on powdery mildew, aphids, barley ...

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

We developed a genome‐integrated CRISPR/Cas12a system for Xenorhabdus budapestensis XBD8, which enables precise deletion or replacement of DNA fragments ranging from 379 to 45,168 bp, with a success rate exceeding 90%. Application of this tool for the dynamic regulation of fabclavine‐8 biosynthesis resulted in a 1.90‐fold increase in production ...

Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...
