健康种子的微生物成分——种子微生物组——似乎是在植物世代之间遗传的，可以动态地影响发芽、植物性能和存活。因此，优化主要作物种子微生物组的方法可能对植物育种和作物改良具有深远的意义，从而提高农业食品、饲料和纤维的产量。在这里，我们描述了一种调节优质作物种子胚胎种子微生物组的新方法，并同时设计了由种子微生物组介导的性状。具体来说，我们发现通过将内生菌Paraburkholderia phytofirmans PsJN引入亲本植物的花中，我们可以驱动其包含在后代种子微生物组中，从而诱导垂直遗传给后代。我们展示了将PsJN引入单子叶和双子叶植物的种子，以及由此引起的小麦种子微生物组组成和生长性状的改变，说明了新型种子微生物组在决定植物性状方面的潜在作用。
The microbial component of healthy seeds – the seed microbiome – appears to be inherited between plant generations and can dynamically influence germination, plant performance, and survival. As such, methods to optimize the seed microbiomes of major crops could have far-reaching implications for plant breeding and crop improvement to enhance agricultural food, feed, and fiber production. Here, we describe a new approach to modulate seed microbiomes of elite crop seed embryos and concomitantly design the traits to be mediated by seed microbiomes. Specifically, we discovered that by introducing the endophyte Paraburkholderia phytofirmans PsJN to the flowers of parent plants we could drive its inclusion in progeny seed microbiomes, thereby inducing vertical inheritance to the offspring generation. We demonstrated the introduction of PsJN to seeds of monocot and dicot plant species and the consequential modifications to seed microbiome composition and growth traits in wheat, illustrating the potential role of novel seed-based microbiomes in determining plant traits.
