Abstract

Ethylene is a gaseous plant hormone that regulates various aspects of growth and development. It promotes shoot growth in etiolated rice seedlings, which is crucial for seedling establishment and has significant agricultural implications. Of the 5 ethylene receptors in rice, OsERS1 is the most abundantly expressed in seedlings. Therefore, we investigated the localization and role of OsERS1 in shoot growth. When expressed in rice protoplasts, OsERS1 was localized in the endoplasmic reticulum. Knockout mutants of OsERS1 exhibited enhanced shoot growth in etiolated seedlings under normal and ethylene-treated conditions. Shoot growth was also enhanced in the OsERS1 mutants under light conditions. Additionally, the induction of ethylene-responsive genes was increased in the mutants, indicating an elevated ethylene response due to the OsERS1 knockout. The mutants also showed increased salt tolerance. In conclusion, our findings suggest that OsERS1 negatively regulates shoot growth and salt tolerance in etiolated rice seedlings.

水稻乙烯受体 OsERS1 负向调节水稻黄化苗的嫩枝生长和耐盐性。

乙烯是一种气体植物激素，调节植物生长发育的各个方面。它促进黄化水稻幼苗的新梢生长，这对幼苗的建立至关重要，具有重要的农业意义。在水稻的5个乙烯受体中，OsERS1在幼苗中表达量最多。因此，我们研究了OsERS1在茎部生长中的定位和作用。在水稻原生质体中表达时，OsERS1定位于内质网。OsERS1基因敲除突变体在正常和乙烯处理的条件下，黄化幼苗的茎部生长增强。在光照条件下，OsERS1突变体的茎部生长也得到了促进。此外，突变体中乙烯应答基因的诱导增加，表明OsERS1敲除导致乙烯应答升高。这些突变体也表现出更高的耐盐性。综上所述，OsERS1负调控黄化水稻幼苗的茎部生长和耐盐性。
