EIN3 and PIF3 interdependently repress chloroplast development in buried seedlings

During embryogenesis, plastids arrest their differentiation as etioplasts (characterized by the distinctive prolamellar bodies, PLBs), and remain poised  to complete their differentiation into functioning chloroplasts upon exposure to light. Liu et al. explored the factors that interact to effect this…

Light controls protein localization through phytochrome-mediated alternative promoter selection ($)

Previous studies have shown that some genes use multiple promoters, but the extent to which this occurs has not been fully resolved. Ushijima et al. showed widespread phytochrome-mediated differential promoter use in response to light. They identified more than 2000 genes with light-dependent alternative…
