摘要： In plants, various proteins are regulated by the ubiquitin-mediated system in response to different environmental stresses, such as drought, cold and heat. The Skp1-Cullin-F-box (SCF) complex, one of the multisubunit E3 ligases, has been shown to be involved in abiotic response pathways. In this study, Glycine max SKP1-like 1 (GmSK1), which had the typical characteristics of an SKP1 protein, with an alpha/beta structure, targeted to the cytoplasm and nucleus, was isolated from soybean [Glycine max (L.)]. GmSK1 was constitutively expressed in all the tested tissues, especially in the roots. Furthermore, the expression of GmSK1 was simultaneously induced by abscisic acid (ABA), jasmonic acid (JA), salicylic acid (SA), NaCl, low temperatures and drought, which suggests important roles for GmSK1 in plant responses to hormone treatments and abiotic stress. GmSK1-overexpressing transgenic tobacco (Nicotiana tobacum cv. Samsun) plants showed enhanced tolerance to high salinity and drought stress; exhibited significantly reduced inhibition of growth, greenness and water loss; and exhibited increased MDA accumulation compared with wild-type controls. Our results suggest that GmSK1 might play a role in the crosstalk between ubiquitination and abiotic stress responses in plants.
