热效应在微生物诱变育种中的应用

摘要

Advances in mechanism and application of the heating effect in breeding of microorganism are reviewed in this paper. Heat produces mutagenesis effect and screening effect. Heating mutagenesis effect is occurred through the substitution of G-C base pair induced by heat, and heating screening effect produces higher forward mutation rate induced by other mutagens.%本文综述了微生物诱变育种中的热效应机理及其应用研究进展.热在微生物诱变育种中具有热诱变效应和热筛选效应,热诱变效应通过热引起DNA中G-C碱基对的置换实现,热筛选效应可以从其他诱变剂诱变的菌体中获得更高的正向突变率.
