Chloroplasts lacking class I glutaredoxins are functional but show a delayed recovery of protein cysteinyl redox state after oxidative challenge

The paper shows that removing class I GRX activity in the chloroplast stroma of P. patens delays protein cysteine redox recovery after oxidative stress without affecting photosynthesis or NPQ.

Root barrier surveillance mechanisms convey soil nitrogen status to shoots

This study rewires root barrier formation to investigate the role of the Schengen pathway in conveying soil nitrogen status to shoots and its impact on root microbiome and plant growth.
