Accordingly , ers2 - 1 is still able to confer ethylene insensitivity via a single receptor gene ers1 in the quadruple mutant , but at a highly reduced level compared to its function in the triple mutants . the major difference between the quadruple and triple mutants is the absence of a wild - type ers2 gene in the quadruple mutant , and we propose that the dominance conferred by ers2 - 1 can be mediated and amplified via the wild - type ers2 to the subfamily i receptor ers1 三突变体的遗传背景与四突变体相比，只是在三突变体中保留了ers2的野生型基因，而当这个野生型的ers2基因突变后，对乙烯不敏感的ers2 - 1基因的功能便减弱了，说明显性基因ers2 - 1在etr1 - 7 ； err2 - 3 ； ein4 - 4三突变体中的功能可以经由活化ers2后再传给ers1 ，而不仅仅是直接传给ers1 。
