A cDNA homologous to the ethylene-response sensors (ERS/ETR1) from Arabidopsis thaliana was isolated from a Rumex palustris cDNA library. This cDNA, RP-ERS1, was 2421 bp long and shared 66% nucleotide homology with ETR1 and ERS in their coding regions. The transcript level of RP-ERS1 was actively regulated during the leafelongation response of R. palustris upon flooding. RP-ERS1 transcript levels increased after submergence, and also after exposure to high concentrations of ethylene and carbon dioxide and low concentrations of oxygen. These results suggest that R. palustris plants may respond to flooding stress by increasing the number of their ethylene receptors.
从酸模叶蓼的cDNA文库中分离出了一个与拟南芥乙烯反应传感器（ERS/ETR1）同源的cDNA。这个名为RP-ERS1的cDNA长度为2421 bp，其编码区与ETR1和ERS的核苷酸同源性为66%。在水淹条件下酸模叶蓼叶片伸长反应过程中，RP-ERS1的转录水平受到积极调控。淹水后，以及暴露于高浓度乙烯、二氧化碳和低浓度氧气后，RP-ERS1的转录水平均有所增加。这些结果表明，酸模叶蓼植株可能通过增加乙烯受体数量来应对水淹胁迫。
