Model summarizing the roles of WHIRLY1 in development-induced senescence. The partitioning of WHY1 between chloroplast and nucleus allows a tight control of the expression of SA biosynthesis and conjugation genes either directly or indirectly. The study by Lin et al. (2020) adds SA to the list of factors that determine the active fraction of WHY1 present in the plastid or the nucleus at different developmental stages. Reprinted from Lin et al. (2020), figure 8.
