​New Study Unlocks Molecular Defense Against Devastating Potato Pathogen​​ (Spongospora subterranea)

A team of plant scientists has made a significant breakthrough in understanding how potato plants defend themselves against Spongospora subterranea f. sp. subterranea (Sss)—the soilborne pathogen that causes powdery scab, an emerging and economically damaging disease affecting potato crops worldwide.

Plant Phototropism Regulated by Acetylation-Phosphorylation Cross-Talk, Study Finds

Researchers discovered that plant phototropism—growth toward light—is fine-tuned by acetylation-phosphorylation cross-talk in the blue-light receptor phototropin 1 (phot1). Acetylation at key lysines, especially K636, regulates phot1’s phosphorylation and activity, with the deacetylase HDA9 balancing these modifications. Light triggers phosphorylation, reducing…
