已知在白杨植物中检测到的稳定蛋白1（SP1）在煮沸时保持可溶，并且转基因白杨中的sp1表达对盐胁迫具有抗性。目前，我们研究了SP1基因在拟南芥中的表达及其对高温胁迫的响应。45 ℃处理16 h后，sp1转基因植株表现出比野生型植株更强的生长，叶绿素、叶绿素荧光、含水量、脯氨酸含量和丙二醛含量等生理特性也更好。这些初步结果表明，SP1基因的过表达可以显著提高转基因小麦的耐热性。拟南芥植物。
It is known that the stable protein 1 (SP1) detected in aspen plants remains soluble upon boiling and that sp1 expression in transgenic aspen is resistant to salt stress. Presently, we analyzed the effect of expression of SP1 in Arabidopsis thaliana plants and their response to high temperature stress. After 45 degrees C for 16 h, relative to wild type plants, sp1 transgenic plants exhibited stronger growth and were better in several physiological properties including chlorophyll, chlorophyll fluorescence, water content, proline content, and malondialdehyde content. These preliminarily results suggest that the over-expression of SP1 may notably enhance heat-tolerant level of transgenic A. thaliana plants.
