Here, there and everywhere: Plastid- and nuclear-localized WHIRLY1 regulates salicylic acid homeostasis during developmental senescence

Does a new job always come with a new location? Perhaps this is true for some plant proteins; half of the proteins are located in more than one subcellular compartment. Emerging evidence in plants shows that nuclear-encoded proteins undergo redox and posttranslational modifications or processing events…

On how to build a larger and healthier Arabidopsis ROSette using a mitochondrial protein (spoiler: reactive oxygen species)

Zones of Defense? SA Receptors Have it Under Control

The constant evolutionary arms race with pathogens has equipped plants with a layered immune system. As the first line of defense, membrane-localized pattern recognition receptors perceive microbe-associated molecular patterns and activate pattern-triggered immunity (PTI). In parallel, R proteins –…

Surprise –salicylic acid receptors can do so much!

Liu et al. investigate the diverse roles of the salicylic acid receptors NPR1, NPR3 and NPR4 in local and long-range plant immunity.
