很明显，不同的植物激素会影响重叠的过程，因此植物激素作用的输出取决于特定的激素组合，而不是每种激素的独立活动。在过去的二十年中，各种植物激素的信号转导途径的许多组成部分已经被确定，导致部分或整个信号级联的阐明。这些发现为开始解决不同激素信号转导途径之间的串扰机制提供了工具。这种串音涉及多种机制，在激素反应和生物合成水平上都起作用，形成了一个微妙的反应网络。本文综述了赤霉素与其他植物激素的相互作用，重点介绍了赤霉素与脱落酸（ABA）、生长素、乙烯和细胞分裂素的相互作用。虽然GA与油菜素内酯（Bouquin et al., 2001）和茉莉酸盐（Traw and Bergelson, 2003）相互作用的证据也存在，但我们的重点是研究控制串音的机制。
It has always been clear that different plant hormones affect overlapping processes, such that the output of plant hormone action depends on specific hormone combinations rather than on the independent activities of each. In the last two decades, numerous components of the signal transduction pathways of various plant hormones have been identified, leading to the elucidation of partial or entire signaling cascades. These findings have provided the tools to begin addressing the mechanisms underlying the cross talk among different hormone signal transduction pathways. Such cross talk involves diverse mechanisms, which act at both the hormone response and biosynthesis levels, creating a delicate response network. In this review, we describe how gibberellin (GA) interacts with other plant hormones, concentrating on its interactions with abscisic acid (ABA), auxin, ethylene, and cytokinin. Although evidence for interactions of GA with brassinosteroids (Bouquin et al., 2001) and jasmonate (Traw and Bergelson, 2003) also exists, we focus on studies addressing the mechanisms governing the cross talk.
