Hybridization has been routinely practiced in agriculture to enhance the crop yield. Principally, it can cause hybrid vigor where hybrid plants display increased size, biomass, fertility, and resistance to diseases, when compared to their parents. During hybridization, hybrid offspring receive a genomic shock due to mixing of distant parental genomes, which triggers a myriad of genomic rearrangements, e.g., transpositions, genome size changes, chromosomal rearrangements, and other effects on the chromatin. Recently, it has been reported that, besides genomic rearrangements, hybridization can also alter the somatic mutation rates in plants. In this review, we provide in-depth insights about hybridization triggered genomic rearrangements and somatic mutations in plants.
杂交在农业中被常规应用以提高作物产量。主要地，它可以引起杂种优势，杂种植物与亲本相比，表现出增大的大小、生物量、生育力和对疾病的抗性。在杂交过程中，杂种后代由于远缘亲本基因组的混合而受到基因组冲击，从而引发大量基因组重排，例如转座、基因组大小变化、染色体重排和染色质的其他影响。最近，据报道，除了基因组重排，杂交还可以改变植物中的体细胞突变率。在这篇综述中，我们深入了解了杂交引发的植物基因组重排和体细胞突变。
