Plant growth and secondary metabolism are commonly regulated by external cues such as light, temperature and water availability.In this study, we examined the effects of low and high temperatures, dehydration, photoperiods, and different growing stages on the changes of steviol glycosides (SGs) contents and corresponding biosynthetic genes expression in Stevia rebaudiana using HPLC and RT-PCR.Our observations showed that all of the fifteen genes were expressed maximally at 25 ℃, and the expressions of some genes were restrained both in low temperature (15 ℃) and high temperature (35 ℃).

【摘要】体育运动项目分为个人运动项目和集体运动项目。在集体运动项目中，各运动员既要按照一定的技战术要求，严格执行战术，又要运动员之间的相互协作、协同配合来完成，在此过程中，除了战术和个人技术之外，还需要运动员具备坚强的意志品质、良好的人际关系、真诚的情感体验、稳定的个性特征、浓厚的兴趣导向等非智力因素，通过集体运动项目的教学、训练和比赛，可以有效的促进高职学生非智力因素的发展。 【关键词】集体运
