Gaining extensive resistance against clubroot disease through the disruption of a susceptibility gene

Journal of Integrative Plant Biology, EarlyView.
This Commentary examines research by Wu et al. showing that β‐1,3‐glucan synthase‐like 5 (GSL5) functions as a key gene for susceptibility to clubroot in Brassica family members by suppressing immunity regulated by jasmonic acid. Inaction of GSL5 through genome editing provides broad‐spectrum resistance to clubroot.

Structure and Evolution of Nearby Stars with Planets. I. Short-Period Systems

, 1998
Using the Yale stellar evolution code, we have calculated theoretical models for nearby stars with planetary-mass companions in short-period nearly circular orbits: 51 Pegasi, Tau Bootis, Upsilon Andromedae, Rho Cancri, and Rho Coronae Borealis.

The Monetary Policy–Commodities Nexus: A Survey

Journal of Economic Surveys, EarlyView.
ABSTRACT This survey synthesizes evidence on the bidirectional links between commodity markets and monetary policy. On the commodities‐to‐policy side, we review how shocks to energy, food, and metals pass through to inflation, inflation expectations, economic activity, and financial stability in state‐dependent ways that vary by shock type, exposure ...

EEG Brain Rhythms During Resting‐State Wakefulness and Sleep in Elderly Expert Meditators

Journal of Sleep Research, EarlyView.
Compared to controls, elderly expert meditators exhibited (1) more preserved resting‐state brain activity, (2) less altered sleep architecture, and (3) EEG features indicative of heightened cognitive states during NREM sleep. Importantly, several of the metrics that differed between groups also showed consistent correlations with meditation expertise ...
