Abstract

Summary The Arabidopsis ABI1 and ABI2 genes encode two protein serine/threonine phosphatases 2C (PP2C). These genes have been originally identified by the dominant mutations abi1–1 and abi2–1, which reduce the plant's responsiveness to the hormone abscisic acid (ABA). However, recessive mutants of A...
