近年来,一些国家的科学家采用辐照的花粉授粉杂交,使供粉植物的部份基因转移到母本基因组内,形成偏母杂种。偏母杂种的绝大部份遗传物质来源于母本,但往往也有少量父本遗传物质掺入。辐照花粉还可望解决远缘杂交不亲和性,使不亲和的亲本杂交成功。本文旨在阐述辐照花粉实现基因转移的有关研究及其进展。 In recent years, scientists in some countries have used irradiated pollination pollination to transfer partial genes of the donor plants into the maternal genome to form a crossbreed hybrid. Most of the genetic material of the mother-of-bred hybrid is derived from the female parent, but there is also a small amount of male-derived genetic material incorporated. Radiation pollen is also expected to resolve distant hybridization incompatibility, so incompatible parental hybrid success. The purpose of this paper is to describe the research and progress of irradiation pollens for gene transfer.
