Key message OG1 is involved in JA-regulated anthesis by modulating carbohydrate transport of lodicules in rice. Abstract Flowering plants have evolved a sophisticated regulatory network to coordinate anthesis and maximize reproductive success. In addition to various environmental conditions, the plant hormone jasmonic acid and its derivatives (JAs) are involved in anthesis. However, the underlying...
Main conclusionYoung Seedling Stripe1 (YSS1) was characterized as an important regulator of plastid-encoded plastid RNA polymerase (PEP) activity essential for chloroplast development at rice seedling stage.Chloroplast development is coordinately regulated by plastid- and nuclear-encoding genes. Although a few regulators have been reported to be involved in chloroplast development, new factors remain...
Plastid-encoded plastid RNA polymerase (PEP), a dominant RNA polymerase in mature chloroplasts, consists of core subunits and peripheral subunits. Despite the importance of the peripheral subunits in control of PEP activity it is unclear how they interact with one another to exert physiological effects on chloroplast development and plant growth, especially in rice. Here, we report a mutant, designated...
