Abstract: The present invention relates to a yeast gene ScFIT3 for regulating and controlling cadmium resistance of an organism and an application thereof. The yeast gene ScFIT3 for regulating and controlling the cadmium resistance of the organism has a nucleotide sequence as shown in SEQ ID NO.1. The present invention discloses, for the first time, the application of the yeast gene ScFIT3 in enhancing cadmium resistance of the organism. The yeast gene ScFIT3 is linked to an expression vector and transformed into a budding yeast, thereby completing construction of a cadmium-resistant yeast. The growth of the budding yeast transformed with the yeast gene ScFIT3 is significantly superior to that of a wild-type budding yeast, indicating that the budding yeast transformed with the yeast gene ScFIT3 has good resistance to cadmium stress, significantly enhances a capability of resisting heavy metal cadmium, and reduces accumulation and absorption of cadmium.
