. A regulatory circuit conferring varied flowering response to cold in annual and perennial plants. Science. 2019;363:409-412 pubmed publisher
..By reconstructing the annual response in perennials, we conclude that characteristic patterns of reproduction in annuals and perennials are conferred through variation in dependency on distinct flowering pathways acting in parallel. ..
