由于分生组织在植物生长和繁殖中的作用，植物中的体细胞突变长期以来一直被怀疑赋予个体植物以及在树木的情况下，单个植物内的个体分枝对植食动物和病原体的抗性。在文献中已经报道了由于体细胞突变引起的对植食性昆虫的抗性的少数实例。最近，一个引人注目的例子证明了体细胞突变如何赋予入侵植物黑藻（Hydrilla verticillata）对除草剂的抗性。操纵基因组的一系列新方法（例如，基因编辑）加上现有的体细胞突变相关抗性的例子表明，这种突变可能在造林、农业和园艺中有用。提出几个关于植物体细胞突变的一般性问题将有助于这种应用：为什么报道的例子如此之少？是否存在其他案件，但由于缺乏足够的注意或方法而未被发现？体细胞突变在什么情况下进入配子体？© 2018化学工业协会。
Because of the role of the meristem in plant growth and reproduction, somatic mutations in plants have long been suspected of conferring herbivore and pathogen resistance on individual plants and, in the case of trees, individual branches within single plants. A few instances of resistance to phytophagous insects owing to somatic mutations have been reported in the literature. More recently, a striking example has demonstrated how somatic mutations confer resistance to an herbicide on an invasive plant, Hydrilla verticillata. The array of new methods for manipulating genomes (e.g., gene-editing) plus existing examples of somatic mutation-associated resistance suggest that such mutations might be useful in silviculture, agriculture, and horticulture. Answering several general questions about somatic mutations in plants would facilitate such applications: Why are so few examples reported? Do other cases exist but go undetected for want of adequate attention or methods? Under what circumstances do somatic mutations enter gametophytes? © 2018 Society of Chemical Industry.
