title: One novel mitochondrial citrate synthase from Oryza sativa L. can enhance aluminum tolerance in transgenic tobacco.
abstract: Rice exhibits the greatest aluminum (Al) tolerance compared with other cereals such as wheat, barley, maize, etc. A full-length gene, OsCS1, encoding citrate synthase, which is highly induced by aluminum toxicity in rice (Oryza sativa L.), was isolated. Sequence analysis and the sub-cellular localization of OsCS1 in yeast revealed that it is a mitochondrial citrate synthase. OsCS1 was induced by Al toxicity. Several independent transgenic tobacco lines expressing OsCS 1 exhibited increased citrate efflux and extraordinary Al tolerance. Possible outlook for OsCS1 to be applied to enhance plant tolerance to Al toxicity was also discussed.
