Summary: By using PCR-RFLP of IGS sequences and sequence analyses of various genes, this study identified diverse Bradyrhizobium species and a novel Bradyrhizobium symbiovar that nodulate peanut in different regions of China. These findings have practical implications for selecting rhizobial inoculants for peanut cultivation in China.

Summary: Symbiotic interaction between legume and rhizobia leads to the formation of nitrogen-fixing nodules. However, little is known about the gene expression of mung bean in response to rhizobial infection. This study analyzed gene expression patterns of mung bean roots inoculated with two symbionts and identified differentially expressed genes related to receptor kinases, plant hormone signal transduction, and metabolism. Additionally, differences were found in DEGs involved in cell communication and plant hormone signal transduction among the two symbiotic systems. This study provides insights into the mechanisms of mung bean's interaction with different rhizobial strains.

Summary: This study found that Bradyrhizobium sp. DOA9 has a broad host range and highly divergent nodulation genes. The duplicated copies of the nodD and nodA genes may affect symbiotic nodulation through functional redundancy. Furthermore, nodA2 and nodB genes play a central role in Nod-Factor biosynthesis and symbiotic nodulation.

Summary: The B-box (BBX) family of proteins in plants, which contain zinc-finger transcription factors, has been found to play crucial roles in various aspects of plant growth and development. While BBX proteins have been identified in several plant species, their presence in maize remains largely unknown. This study identified and characterized 36 maize BBX proteins, and found that they share similar domains, motifs, and genomic structures within clades. Furthermore, the study analyzed the expression patterns of these proteins and their interactions using bioinformatic tools and experimental assays. These findings provide valuable information for understanding the complexity and functions of the ZmBBX family.

Summary: The study expanded the catalog of T3SS effectors of Bradyrhizobium vignae ORS3257 using a multi-omics approach, showing that most of the putative effectors are regulated by TtsI and confirming the secretion of some T3Es through proteome analysis. Additionally, the research identified and validated a new potential T3Es.

Summary: In rice, OsMADS32 regulates floral patterning through interactions with proteins like OsMADS6, playing crucial roles in defining stamen, pistil, ovule development, and floral meristem identity. OsMADS32, an orphan gene absent in eudicots, integrates the action of other MADS-box homeotic proteins to sustain floral organ specification and development.

Summary: This review provides an overview of the functions and mechanisms of DEAD-box family proteins in HIV-1 vRNA metabolism. It discusses the implications of these interactions in viral infection, viral latency, and cell death, and speculates on the potential of DEAD-box protein inhibitors as therapeutics for controlling the HIV-1 pandemic.

Summary: In this study, soaking maize seeds in Bradyrhizobium japonicum significantly increased the roots, stalks, and fresh weight of maize. Transcriptome sequencing results showed that multiple growth and development-related genes were highly up-regulated in the whole maize plant soaked in B. japonicum. Moreover, the abundance of plant growth promoting bacteria increased while the abundance of multiple pathogens decreased. Inoculation with B. japonicum also inhibited the infection of the pathogen Fusarium graminearum in maize. These findings suggest that soaking seeds in B. japonicum can affect the expression of maize growth and development-related genes through changing the soil microorganism community structure, providing new opportunities for food security.

Summary: Microbiota play a crucial role in modulating susceptibility to Type 1 diabetes, with the association of microbiota composition with genetic risk and immune responses. The role of inflammasomes in Type 1 diabetes and the development of inhibitors for therapeutically targeting inflammasomes are areas that require further study.

Summary: The plant hormone abscisic acid (ABA) plays a versatile and crucial role in plant immunity along with promoting abiotic stress responses. This study reveals that NPR1 acts as a positive regulator of ABA-responsive genes and is induced transcriptionally by ABA. Additionally, NPR1 is degraded through the action of HOS15 in a proteasome-dependent manner.

Summary: This study identifies 13 novel proteins associated with Nod factor receptors and describes a potential interacting protein, GmBI-1a. GmBI-1a has a strong positive correlation with GmNFR1a and its expression is enhanced by rhizobial infection. Overexpression of GmBI-1a promotes nodule formation, while down-regulation reduces nodule number. The study provides new insights into the regulatory mechanism of GmNFR1a in the symbiotic process.

Summary: This study identified 27 SFBB genes in 'Yali' pear using transcriptome sequencing and PCR techniques. It found that SFBB genes from Pyrus were divided into 26 types and showed high intrahaplotypic divergence, comparable to the allelic diversity of S-RNase. These findings provide insights into the self-incompatibility system in pears.
