We previously reported on the strong symbiosis of AMF species (Rhizophagus irregularis CD1) with the cotton (Gossypium hirsutum L.) which is grown worldwide. In current study, it was thus investigated in farmland to determine the biological control effect of AMF on phosphorus acquisition and related gene expression regulation, plant growth and development, and a series of agronomic traits associated with yield and fiber quality in cotton. When AMF and cotton were symbiotic, the expression of the specific phosphate transporter family genes and P concentration in the cotton biomass were significantly enhanced. The photosynthesis, growth, boll number per plant and the maturity of the fiber were increased through the symbiosis between cotton and AMF. Statistical analysis showed a highly significant increase in yield for inoculated plots compared with that from the non inoculated controls, with an increase percentage of 28.54%. These findings clearly demonstrate here the benefits of AMF-based inoculation on phosphorus acquisition, growth, seed cotton yield and fiber quality in cotton. Further improvement of these beneficial inoculants on crops will help increase farmers' income all over the world both now and in the future.
我们之前曾报道过 AMF 物种（Rhizophagus irregularis CD1）与全球种植的棉花（Gossypium hirsutum L.）之间的强烈共生关系。在当前的研究中，我们在农田中进行了调查，以确定 AMF 对磷获取和相关基因表达调控、植物生长发育以及与产量和纤维质量相关的一系列农艺性状的生物控制作用对棉花的影响。当 AMF 与棉花共生时，棉花生物量中特定磷酸盐转运体家族基因的表达和磷浓度显著增强。通过棉花与 AMF 的共生，提高了光合作用、生长、单株棉铃数和纤维成熟度。统计分析显示，接种区的产量与未接种对照区相比有显著增加，增加百分比为 28.54%。这些发现清楚地表明，基于 AMF 的接种对棉花的磷获取、生长、皮棉产量和纤维质量有好处。未来进一步改进这些有益的接种剂将有助于提高全球农民的收入。
