含有1-氨基环丙烷-1-羧酸（ACC）脱氨酶的植物生长促进细菌通过降低植物乙烯水平促进植物生长和发育，特别是在各种环境胁迫之后。在这篇综述中，这种生长促进作用的生理基础进行了详细的研究。此外，模型提出，努力解释（一）乙烯对植物的应激反应看似矛盾的影响，（二）如何表达这种酶是转录调节在许多细菌菌株和（iii）如何ACC脱氨酶含有植物生长促进细菌改变植物基因表达和积极调节植物生长。
Plant growth-promoting bacteria that contain the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase facilitate plant growth and development by decreasing plant ethylene levels, especially following a variety of environmental stresses. In this review, the physiological basis for this growth-promotion effect is examined in some detail. In addition, models are presented that endeavour to explain (i) the seemingly paradoxical effects of ethylene on a plant's response to stress, (ii) how the expression of this enzyme is transcriptionally regulated in many bacterial strains and (iii) how ACC deaminase-containing plant growth-promoting bacteria alter plant gene expression and positively modulate plant growth.
