  "summary": "Overwintering plants increase their tolerance to freezing in two phases: the first-phase, known as cold acclimation (CA), occurs at chilling temperatures, followed by second-phase acclimation at sub-zero temperatures. We previously showed that second-phase freezing acclimation (2PFA), in which cold-acclimated Arabidopsis is exposed to -2{degrees}C with extracellular ice formation under light,…",
