摘要
Although much is now known about fumarate metabolism, our knowledge of some aspects of its biological function remain far from comprehensive. In this short review we begin with an introductory overview of the role of fumarate in both plant and non-plant systems. We next highlight the relative importance of fumarate in relation to cell type and circumstance in contrast to other chemically similar organic acids. Considerable cumulative evidence is suggestive of a role for fumarate in pH regulation during nitrate assimilation and that fumarate has similar effects as malate during stomatal movement. Indeed it is currently difficult to separate the biological function of fumarate from malate under certain circumstances. However, in other cases this can be easily performed. This physiological complexity notwithstanding it remains possible that the engineering of fumarate metabolism may provide opportunities to improve plant growth and performance. (C) 2011 Elsevier Ltd.
