生物诱变是基于植物病原能够诱导其寄主性状产生可遗传的变异这一试验事实,并参照物理诱变、化学诱变而提出的一个新概念。虽然在微生物、组织培养、质粒以及生物因子致癌等研究领域中常常涉及到生物因子的致突变现象,如1962年Alikhanian观察到放线菌噬菌体的诱变效应, Biological mutagenesis is based on the experimental fact that plant pathogens induce heritable traits in their host traits and refers to a new concept proposed by physical mutagenesis and chemical mutagenesis. Although the mutagenesis of biological factors is often involved in the research fields of microorganisms, tissue culture, plasmids and carcinogenesis of biological factors, such as the Alkhanian mutagenesis effect of actinomycetes was observed in 1962,
