Abstract ：
Synthetic microbial communities (SynComs) are a promising tool for making full use of the beneficial functions imparted by whole bacterial consortia. However, the complexity of reconstructed SynComs often limits their application in sustainable agriculture. Furthermore, inter-strain interactions are often neglected during SynCom construction. Here, we propose a strategy for constructing a simplified and functional SynCom (sfSynCom) by using elite helper strains that significantly improve the beneficial functions of the core symbiotic strain, here Bradyrhizobium elkanii BXYD3, to sustain the growth of soybean (Glycine max). We first identified helper strains that significantly promote nodulation and nitrogen fixation in soybean mediated by BXYD3. Two of these helper strains assigned to the Pantoea taxon produce acyl homoserine lactones, which significantly enhanced the colonization and infection of soybean by BXYD3. Finally, we constructed a sfSynCom from these core and helper strains. This sfSynCom based on the core-helper strategy was more effective at promoting nodulation than inoculation with BXYD3 alone and achieved effects comparable to those of a complex elite SynCom previously constructed on the basis of potential beneficial functions between microbes and plants alone. Our results suggest that considering interactions between strains as well as those between strains and the host plant might allow construction of sfSynComs.

Abstract ：
Auxin is the most important phytohormone, regulating root growth and development in plants. ARFs function as central regulators in auxin signaling in model plants, and the functions of ARF activators have been widely investigated, while the functions of ARF repressors remain elusive. In this study, we investigated the family of GmARFs in soybean through a genome-wide expression pattern and functional study of roots highly expressing ARFs. In total, we identified 59 GmARF members in the soybean genome. GmARFs harbor canonical B3 DNA-binding (B3), ARF (Aux rep), and PB1 functional protein domains. We identified two potential repressor genes, GmARF9b (Glyma.03G070500) and GmARF2a (Glyma.05G200800), which are specifically or highly expressed in the roots. Histochemical staining suggested that both genes are primarily expressed in the stele, root tips, and lateral root primordia. Subcellular localization analysis showed they were mainly localized in the nucleus. Overexpression of GmARF9b and GmARF2a significantly inhibited root growth using a transgenic hairy root assay. Root section analysis further suggested that GmARF9b and GmARF2a negatively regulated cortical cell layers and the longitudinal cell length of roots, thereby modulating root growth. Overall, this study has preliminarily identified two GmARFs that inhibit root growth in soybean. This discovery has deepened our understanding of the functions of ARFs in root development and has provided guidance for breeding crop roots with improved nutrient use efficiency.

Abstract ：
Lilies (Lilium spp.) are important economic horticultural plants with applications in ornamental horticulture, food, and traditional medicine. However, continuous cropping obstacles (CCOs) severely impact lily cultivation, causing yield and quality losses. This study investigates application of crop rotation, particularly with rice, to mitigate CCOs in "multi-functional lily" hybrids. Through comparative field trials of continuous monoculture (NR), maize rotation (MR), and rice rotation (RR) systems, we demonstrate that RR significantly alleviates CCOs by restructuring rhizosphere microbial communities, enhancing secondary metabolite accumulation, and enriching Aspergillus populations. Rice rotation promotes Aspergillus proliferation, the average relative abundance (RA) of Aspergillus in RR increased to 59.00%, raising by nearly 60 times compared with that in NR condition (RA=1.05%). Rice rotation activates jasmonic acid (JA) biosynthesis, suppressing fungal pathogens (Fusarium spp. and Botrytis spp.) and boosting medicinal alkaloid production in bulbs. Our findings provide a sustainable, cost-effective solution for CCO mitigation, highlighting the vital role of Aspergillus as a biocontrol agent and a promoter of plant defense mechanisms. This study offers novel insights into the agroecological benefits of ricelily rotation, advancing sustainable lily cultivation practices through rice rotation and microbial management.

Abstract ：
Microbiota-mediated nutrient turnover in the rhizosphere determines nutrient bioavailability, thereby enhancing nutrient uptake, utilization, and ultimately crop productivity. Consequently, elucidating the functional core microbiota in rhizosphere nutrient turnover is of critical importance. In this study, we leveraged soybean germplasm core collections to investigate the tripartite relationship among host genotype, core microbiota and nutrient availability, with a focus on delineating the pivotal role of core microbiota in nutrient turnover. Our results suggest that phylogenetic variation significantly shape root-associated microbial communities and rhizosphere nutrient availability, explaining 11.75 % and 2.07 % of total variances, respectively. Core microbiota analysis identified 29 phylogenetic conserved core amplicon sequence variants (ASVs), the majority of which exhibited significant correlated with nutrient availability. Notably, three key core ASVs-ASV13, ASV14 and ASV12, positively correlated with alkali-hydrolyzed nitrogen, available phosphorus, and soil organic matter, respectively. These taxa were subsequently incorporated into a Bradyrhizobium-based synthetic bacterial community (SynCom) to validate their functional roles. Further experiments confirmed that core microbiota-driven nutrient turnover directly facilitates host plant, as evidenced by SynCom inoculation assays. Collectively, this study establishes that phylogenetically conserved core microbiota critically regulate nutrient turnover and acquisition efficiency in the rhizosphere. These insights advance our understanding the ecological function of core microbiota in the rhizosphere and provide a framework for harnessing the beneficial traits in sustainable agriculture.

Abstract ：
Soil legacy effects, especially soil bacterial legacy effects, influence growth, fitness and nutrient acquisition in sequential cropping systems. To date, mechanisms underlying soil bacterial legacy influences on subsequent crops remain largely unknown. In this study, we employed soybean monoculture (S), corn monoculture (C), and soybean/corn intercropping (SC) to study soil legacy effects on the growth and nutrient acquisition of wheat. In these tests, S, C and SC drove establishment of distinctive soil bacterial communities, with higher abundances of Actinobacteria and Proteobacteria taxa observed in SC plots than in S and C treatments. Variation among soil bacterial communities was associated with functional shifts in nitrogen cycling in SC treatment compared to other treatments(C and Control). Soil legacy effects in turn may contribute to growth, nutrient acquisition and grain production in wheat crops planted in rotations. Pot assay suggest that soil microorganism of SC treatment significantly increased the plant height of wheat by 15.1 % and 18.7 %, the shoot biomass by 50.7 % and 62.7 %, the nitrogen content by 76.0 % and 94.9 %, the phosphorus content by 80.3 % and 75.9 %, and the potassium content by 64.0 % and 83.7 % by compared with C and S. Actinobacteria taxa collections further promote nutrient acquisition of wheat. Taken together, our observations from field plots and manipulation of specific bacterial taxa revealed novel soil bacterial legacy effects of previously reared crops on subsequent crops. These new insights open avenues for using soil legacy effects for positive impacts in crop rotation systems.

Abstract ：
Associative nitrogen fixation contributes large portion of N input to agro-ecosystems through monocot-diazotrophic associations. However, the contribution of associative nitrogen fixation is usually neglected in modern agriculture, and the underlying mechanisms of association between monocot and diazotrophs remain elusive. Here, we demonstrated that monocot crops employ mucilage and associated benzoic acid to specially enrich diazotrophic partners in response to nitrogen deficiency, which could be used for enhancing associative nitrogen fixation in monocot crops. To be specific, mucilage and benzoic acid induced in sugarcane roots by nitrogen deficiency mediated enrichment of nitrogen-fixing Paraburkholderia through specific recruitment whereas other bacteria were simultaneously repelled. Further studies suggest maize employs a similar strategy in promoting associations with diazotrophs. In addition, our results also suggest that benzoic acid application significantly increases copy numbers of the nifH gene in soils and enhances associative nitrogen fixation in maize using 15N enrichment assay. Taken together, these results reveal a mechanism regulating the association between monocot crops and nitrogen-fixing bacteria, and, thereby point towards ways to harness these beneficial microbes in efforts to increase nitrogen efficiency in monocot crops through pathways regulated by a specific signaling molecule.
