Arabidopsis acclimation to daily environmental fluctuations converts a defense response regulator into a susceptibility factor toward Sclerotinia Acclimation enables plants to adjust to immediate environmental fluctuations and is therefore key to the resilience of plant disease resistance in a time of climate change. Here, we report on the ac.....

A dual role of Arabidopsis PAL nuclear localization in fine tuning flavonoid biosynthesis PAL’s dual localization links metabolism with transcription, revealing feedback that fine-tunes phenylpropanoid regulation.

Interesting paper: Metabolic enzyme PAL can go into the nucleus in response to high product build up and sequester an activating TF of the pathway, thus acting as a feedback inhibition loop.
