摘要

与亲本中的任何一方相比，植物的杂交活力能使后代具有更好的农艺性状。最近，Wang 等人报道了番茄中用于克隆配子生产的有丝分裂代替减数分裂（MiMe）系统，通过将来自四个祖先的基因组堆叠在四倍体杂交种中，展示了利用自多倍体渐进异交的潜力，四倍体杂交种是由 MiMe 杂交种杂交而成的。

Clonal gamete-mediated polyploid genome design for stacking genomes

Hybrid vigor in plants confers better agronomically significant traits in offspring compared with either parent. Recently, Wang et al. reported a mitosis instead of meiosis (MiMe) system in tomato for clonal gamete production, showing the potential to exploit autopolyploid progressive heterosis by stacking genomes from four grandparents in tetraploid hybrids, developed from crossing MiMe hybrids.
