摘要

Eukaryotic translation initiation factors (eIFs) have been shown to be critical in the initiation of protein synthesis. Here, we report the cloning and characterization of a novel gene, LceIF1, from a potentially interesting forage grass, Leymus chinensis (Trin.). The expression results show that LceIF1 is expressed in most organisms under normal conditions, but the transcription patterns differ under sodic-saline and sodic-alkaline stresses. Sodic-saline stress induced a persistent decrease, and sodic-alkaline stress induced overexpression of LceIF1. Potassic-saline and alkaline stresses did not cause any changes in expression of eIF1. These results indicate that not only pH but also Na+ concentration affects overtranscription of LceIF1. The eIF1 transgenic lines showed relatively high eIF1 expression, resulting in potentially higher stress resistance. Combined with eIF1 transcription in transgenic lines, LceIF1 as a molecular target of salt toxicity is believed to help enhance salt tolerance.
