In nature, symbiosis with arbuscular mycorrhizal (AM) fungi contributes to sustainable acquisition of phosphorus and other elements in over 80% of plant species; improving interactions with AM symbionts may mitigate some of the environmental problems associated with fertilizer application in grain crops such as rice. Recent developments of high-throughput genome sequencing projects of thousands of rice cultivars and the discovery of the molecular mechanisms underlying AM symbiosis suggest that interactions with AM fungi might have been an overlooked critical trait in rice domestication and breeding. In this review, we discuss genetic variation in the ability of rice to form AM symbioses and how this might have affected rice domestication. Finally, we discuss potential applications of AM symbiosis in rice breeding for more sustainable agriculture.
在自然界中，与丛枝菌根（AM）真菌共生有助于 80%以上的植物物种可持续地获取磷和其他元素；改善与 AM 共生体的相互作用可能会减轻与肥料应用相关的一些环境问题，如水稻等粮食作物。高通量基因组测序项目对数千个水稻品种的最新发展以及 AM 共生关系的分子机制的发现表明，与 AM 真菌的相互作用可能是水稻驯化和选育过程中被忽视的关键特征。在这篇综述中，我们讨论了水稻形成 AM 共生关系的能力的遗传变异，以及这可能如何影响水稻的驯化。最后，我们讨论了 AM 共生在水稻选育中的潜在应用，以实现更可持续的农业。
