タイトル: Seasonal switching of integrated leaf senescence controls in an evergreen perennial Arabidopsis著者: Yumoto, Genki; Nishio, Haruki; Muranaka, Tomoaki; Sugisaka, Jiro; Honjo, Mie N.; Kudoh, Hiroshi抄録: Evergreeness is a substantial strategy for temperate and boreal plants and is as common as deciduousness. However, whether evergreen plants switch foliage functions between seasons remains unknown. We conduct an in natura study of leaf senescence control in the evergreen perennial, Arabidopsis halleri. A four-year census of leaf longevity of 102 biweekly cohorts allows us to identify growth season (GS) and overwintering (OW) cohorts characterised by short and extended longevity, respectively, and to recognise three distinct periods in foliage functions, i.e., the growth, overwintering, and reproductive seasons. Photoperiods during leaf expansion separate the GS and OW cohorts, providing primal control of leaf senescence depending on the season, with leaf senescence bein ...
