Abstract
Successful soybean and rhizobium interaction is characterized by the formation of root nodules. This symbiosis significantly affects the growth and yield of soybeans and has long been recognized as a key factor in sustainable agricultural systems. Naturally, soybeans could form a tripartite symbiotic relationship with rhizobium and arbuscular mycorrhizal fungi (AMF). However, there is no information regarding the symbiotic potential of soybean, nodulating bacteria, and dark septate endophytic (DSE) fungi. This study aims to delve into new tripartite symbiosis potential, shedding light on its efficacy in improving soybean growth while reducing environmental impacts. We examined the effect of incorporating two DSEs: Cladophialophora chaetospira SK51 (Cc) and Veronaeopsis simplex Y34 (Vs), into the classic soybean-rhizobium symbiosis. Under sterile conditions, the co-inoculation of DSEs with Bradyrhizobium japonicum IncB6 (Bj) significantly increased the nodule number and dry weight, leading to the acceleration of soybean vegetative growth. Soybean nodule numbers under co-inoculation treatments-CcBj and VsBj-were significantly increased by 77.6 and 43.6%, respectively, compared to the Bj treatment. Furthermore, under the CcBj and VsBj treatments, the soybean nodule dry mass was significantly increased by 455 and 363%, respectively, compared to Bj. This finding represents the first report of new beneficial tripartite symbiosis potential for soybean nodulation and vegetative growth.
