Summary: A lack of soil phosphorus is a limiting factor for Lotus corniculatus growth in Guizhou Province, China. This study investigated the response mechanism of L.corniculatus to low-phosphorus stress using morphological, physiological, and transcriptome analysis. The results showed that a low-phosphorus tolerant line exhibited better performance and various morphological and biochemical changes were observed under low-phosphorus stress. Transcriptome analysis also identified differentially expressed genes and related pathways associated with low-phosphorus stress.

Summary: Pinitol is transported passively across the symbiosome membrane in Lotus japonicus by the energy-independent polyol transporter LjPLT11. Its accumulation is crucial for maintaining osmotic balance in nodules. The disruption of symbiosome membranes, reduced nitrogen fixation, and increased production of reactive oxygen species in LjPLT11 RNAi lines indicate the importance of LjPLT11 in nodules.

Summary: A chemoattractant of plant-parasitic root-knot nematodes has been isolated from the Super-growing Root culture system and found to be enriched in carbohydrates, particularly arabinose and galactose. This attractant is essential for the attraction of Meloidogyne incognita but not other nematode species.

Summary: In this study, the researchers found that hmuS(pSym) of M. amorphae CCNWGS0123 plays a crucial role in rhizobial infection, nitrogen fixation, and nodule development in symbiosis with Robinia pseudoacacia. The protein HmuS(pSym) is involved in heme-binding and is strongly expressed in the nitrogen-fixation zone of mature nodules. The inactivation of hmuS(pSym) leads to the impairment of bacteroid survival and defense reaction in root nodules.

Summary: This study examined the potential of a Lactobacillus acidophilus-mediated bioconverted product from Lotus corniculatus seed to reduce axillary malodor and its impact on the associated microbial community. The findings revealed that BLC treatment reduced the intensity of body odor, decreased odor-producing bacteria such as Corynebacterium and Anaerococcus, and enhanced the richness and network density of the microbial community. These results suggest that BLC has promise as a deodorant material in cosmetic products.

Summary: Legumes form a symbiosis with rhizobia to access atmospheric nitrogen for plant growth. The process is energetically demanding, with a high demand for carbon supplied as sucrose. Transport pathways for malate and other organic acids to support nitrogen-fixing bacteroids have been identified, but further research is needed.

Summary: This article discusses the roles of reactive oxygen, nitrogen, and sulfur species, as well as antioxidants, in the metabolic regulation and signaling of legume nodules. The article also raises several key questions, such as the need for new methodologies to detect and quantify these reactive molecules, the regulation of redox-active proteins, and the potential crosstalk between reactive oxygen, nitrogen, and sulfur species in nodules.

Summary: In this study, a genomic variation map of 272 L. corniculatus accessions was created through genome resequencing. The analysis revealed high genetic diversity and the division of accessions into three subgroups, with the genetic diversity centers located in Transcaucasia. Candidate genes and SNP sites associated with CNglcs content and growth traits were identified. The study also provided insights into molecular studies and breeding of CNglcs and growth traits in L. corniculatus.

Summary: In the symbiosis of M. truncatula-Sinorhizobium meliloti, MtMIF3 is mainly expressed in the nitrogen-fixing zone of the nodules. Silencing MtMIF3 increased nodule numbers but resulted in higher bacteroid degradation in the infected cells of the nitrogen-fixing zone, indicating premature aging. On the other hand, overexpression of MtMIF3 inhibited nodule senescence.

Summary: Salinity is a major abiotic stress for plants, impacting crop growth and yield especially in arid regions. Plant growth-promoting bacteria (PGPB) offer a sustainable and cost-effective solution to enhance plant tolerance to salt stress by altering plant hormonal balance, releasing beneficial compounds, regulating internal ionic content, and aiding in the synthesis of osmoprotectant compounds. The use of PGPB is a valuable resource for improving plant tolerance to salinity and increasing global food production sustainably.

Summary: The genomes of endophytic bacteria isolated from legume nodules contain genes related to quorum sensing, biofilm formation, and plant growth promotion. Inoculation of these strains in lettuce and carrot increased crop yield by more than 20% and 10% respectively, confirming their potential as plant biostimulants. Genome mining of genes involved in plant colonization and growth promotion is a promising strategy for selecting effective bacterial strains for crops inoculation.

Summary: Pseudomonas is a diverse and widely distributed genus of bacteria that plays important roles in the biology of earth and living beings. Its taxonomic organization remains challenging due to the increasing number of new species and the use of genomics for analysis. This research proposes the creation of three new genera to classify species previously included in Pseudomonas and to reclassify several species within existing taxa based on genome analyses.

Summary: Microbes produce a wide range of secondary metabolites with various biological activities through biosynthetic gene clusters. This study focuses on the genus Pseudomonas and reveals the main biosynthetic systems related to secondary metabolism, investigates the evolutionary processes that drive the diversification of their coding regions, and identifies Pseudomonas strains with potential for producing useful natural products. The results show that Pseudomonas type strains predominantly encode non-ribosomal peptide synthetases, bacteriocins, N-acetylglutaminylglutamine amides and beta-lactones.

Summary: The rapid expansion of degraded soil poses challenges to agricultural crop yield and increases the risk of food scarcity globally. Plant growth-promoting rhizobacteria (PGPR) have been recognized for their ability to reduce plant stress. However, the field-level plant stress caused by degraded soil is not fully addressed. Therefore, combining methods such as CRISPR and nanotechnology with PGPR could effectively manage degraded soil.

Summary: Each Earth ecosystem has unique microbial communities, and Pseudomonas bacteria have evolved to adapt to different ecological niches and interact with different hosts. This study revealed the functional divergence of Pseudomonas depending on the niche, with each group of strains from a certain environment harboring distinct metabolic pathways or functions. Horizontal gene transfer was found to occur mainly between closely related taxa and was dependent on the isolation source. Additionally, numerous undescribed proteins and functions associated with each Pseudomonas lifestyle were discovered.
