Salicylic acid (SA) is a plant hormone almost exclusively associated with the promotion of immunity. It is also known that SA has a negative impact on plant growth, yet only limited efforts have been dedicated to explain this facet of SA action. In this review, we focus on SA-related reduced growth and discuss whether it is a regulated process and if the role of SA in immunity imperatively comes with growth suppression. We highlight molecular targets of SA that interfere with growth and describe scenarios where SA can improve plant immunity without a growth penalty.
水杨酸(SA)是一种几乎专门与免疫促进相关的植物激素。人们还知道SA对植物生长有负面影响,但致力于解释SA作用这一方面的努力有限。在本综述中,我们聚焦于SA相关的生长减缓,并讨论这是否是一个受调控的过程,以及SA在免疫中的作用是否必然伴随着生长抑制。我们强调了SA干扰生长的分子靶点,并描述了SA可以在不影响生长的情况下提高植物免疫力的情形。
