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 ：
Phosphorus (P) is an essential yet frequently deficient plant nutrient. Optimizing P distribution and recycling between tissues is vital for improving P utilization efficiency (PUE). Yet, the mechanisms underlying the transport and re-translocation of P within plants remain unclear. Here, wide-ranging natural diversity in seed P allocation and positive correlations among yield traits were found using 190 soybean accessions in field trials. Among them, the P-efficient genotype BX10 outperformed BD2 in assessments of PUE that were largely explained through differences in P redistribution from pods to seeds under low P stress. Pods of BX10 were therefore subjected to transcriptome analysis, and GmVPE1 was identified as a vacuolar Pi transporter to investigate further. Importantly, significant DNA polymorphism in GmVPE1 promoter regions was remarkably associated with seed weight among soybean accessions grown on P-deficient soils. Further analyses suggested that mRNA abundance of GmVPE1 in haplotype 2 (Hap) is significantly higher than that GmVPE1Hap1. GmVPE1 was highly upregulated by P deficiency and preferentially expressed in pods, seeds, and seed coats, which was consistent with GUS staining using transgenic soybean plants carrying pGmVPE1Hap2::GUS. Near-isogenic lines carrying the GmVPE1Hap2 allele, along with stable transgenic soybeans overexpressing GmVPE1 in a GmVPE1Hap1 background, had increases in PUE, more seed setting, and greater yields in both greenhouse and field trials than control plants. In summary, natural variation among GmVPE1 alleles determines genetic expression and subsequent P re-translocation phenotypes, which impacts PUE and yield, and thereby makes this an important genetic resource for soybean molecular breeding.

Abstract ：
Pleasant aroma is a distinctive character of Wuyi Rock tea, but its optimization through agricultural practices remains largely unexplored. Here, we conducted a two-year field trials in the core-region of Wuyi Rock tea production area with organic or chemical fertilizer. The results indicated that organic fertilizer significantly improves soil fertility, as indicated by increased pH and organic matter. GC-MS analysis showed that organic fertilizer obviously affects the aroma metabolites in tea leaves, with the levels of 1-Hexanol (C6H14O), 2-Ethyl-1-hexanol (C8H18O), (E,E)-2,4-Heptadienal (C7H10O), E-Nerolidol (C15H26O) and 3-octen-2-one (C8H14O) increasing by 56.55%, 104.44%, 64.39%, 64.10% and 48.10%, respectively, compared to chemical fertilizer, thereby improving its aroma quality. The correlation analysis and PLS-PM model combined with the results from ionomics and metabolomics, further elucidated that soil fertility significantly impacted the mineral nutrients in tea leaves, thereby regulating the content of volatile metabolites. Altogether, the research findings provide practical fertilizer usage guidelines for tea farmers, helping to improve the aroma quality and overall market value of tea.

Abstract ：
Legume plants commonly associate with both arbuscular mycorrhizal (AM) fungi and rhizobia and thus enhance the acquisition of phosphorus (P) and nitrogen (N) nutrition. Inoculation with AM fungi can promote nodulation and N-2 fixation of legume plants; however, the underlying mechanisms remain poorly understood. Here, root exudates collected from AM-colonised soybean plants showed greater accumulation of the specific flavonoids (daidzein and genistein) and phenolic acids (benzoic acid and p-Hydroxybenzoic acid), and significantly promoted nodulation. Furthermore, the exudates from AM-colonised roots and the derived specific flavonoids and phenolic acids effectively increased rhizobial growth, chemotaxis, biofilm formation. Addition of the specific synthetic root exudates enhanced nodulation and N-2 fixation, and expression of the core nodulation genes in soybean. Overexpression of a phenylalanine ammonia-lyase gene, GmPAL2.4 markedly upregulated the expression of the genes related to the biosynthesis of daidzein, genistein, benzoic acid, and p-Hydroxybenzoic acid, and increased accumulation of these specific flavonoids and phenolic acids in the transgenic plants, thus enhancing nodulation and N-2 fixation. In summary, we demonstrated a crucial role of specific flavonoids and phenolic acids induced by AM symbiosis in promoting rhizobium-host symbiosis. This offers a pathway for improving symbiotic efficiency through the use of specific synthetic compounds.

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 ：
Lignification of juice sacs is a primary contributor to reductions in fruit quality, with impacts on taste and economic value of pomelo (Citrus grandis). To date, information on the regulation of fruit lignification remains fragmentary. In this study, we first analyzed the relationship between lignification and nutrient status of pomelo juice sacs, which revealed a significant positive correlation between nitrate (NO3-) concentration and lignin concentration, with over 60% of lignin accumulation explained by NO3- levels in three models of machine learning-based regression. Results from field trails in 11 pomelo orchards, as well as in pear fruits and soybean roots exposed to low or high NO3- supplies, further demonstrated that nitrate plays an important role in lignification. Transcriptomic analysis further showed that pomelo laccases (CgLACs) were more intensively up-regulated upon addition of NO3- than any of the genes encoding one of the other 12 enzymes involved in lignin biosynthesis. Among the nine identified CgLACs, CgLAC3 was the most significantly up-regulated CgLAC in high nitrate treated plants. Over-expressing CgLAC3 increased lignin concentrations in both pomelo albedo and soybean hairy roots. Taken together, we conclude that nitrate modulates fruit lignification in pomelo through regulation of CgLAC3 expression, which suggests that NO3--N fertilization may affect fruit lignification, and thereby can be managed to improve fruit quality.
