Summary: Plants can make conditional decisions when choosing rhizobial strains, tolerating intermediate nitrogen-fixing strains based on their fixation ability. Plants typically sanction nonfixers and only tolerate intermediate fixers when a better strain is not available. This demonstrates that plants have remarkable control over their symbiotic partners by comparing local and global cues in order to optimize nitrogen fixation.

Summary: Plants establish symbiotic relationships with mutualistic fungi and bacteria, such as arbuscular mycorrhizal (AM) fungi and rhizobia, to exchange key nutrients and promote growth. Our research demonstrates that the AM symbiosis is crucial for assembling a normal quantitative root-associated microbiota in native soil, impacting Rhizobiales hubs among plant microbiota and benefiting the plant holobiont. Furthermore, our findings suggest that the interactions between AM and rhizobial symbioses play a key role in promoting nodulation in legume plants in native soil, with implications for agricultural management strategies.

Summary: Post-embryonic organogenesis in plants enables them to be developmentally responsive to their environment, leading to opportunities for growth and structural remodeling that are unique compared to other higher order organisms. The plasticity in plant development makes plant-microbe interactions a fascinating field to study symbiosis. This review focuses on how beneficial microbes alter root growth, development, and architecture, dissecting the cell biology and molecular mechanisms underlying these interactions in a tissue-specific manner.

Summary: Biological nitrogen fixation by Rhizobium-legume symbioses provides an eco-friendly alternative to chemical nitrogen fertilizers in legume crops, with rhizobial inoculants playing a crucial role in sustainable agriculture. However, challenges such as competition with native strains, lack of persistence, and gene transfer limitations need to be addressed for optimal performance in the field.

Summary: Growing evidence shows the essential role of plant hormone cytokinins (CKs) in nitrogen-fixing symbiosis, with ABC transporter ABCG56 playing a crucial role in the early nodulation stages by exporting bioactive CKs in an ATP-dependent manner. Disruption of ABCG-mediated cytokinin transport impairs nodulation, highlighting the importance of this process in the establishment of N-fixing nodules.

Summary: Split-root assays are widely used in studies focusing on the regulatory mechanisms in legume-rhizobia symbioses, allowing separate treatment of divided root sections to monitor local and systemic plant responses. Various techniques can be used to establish split-root assemblies, mainly used in legume studies to understand mechanisms related to root nitrogen rhizodeposition, belowground nitrogen transfer, and nodulation regulation.

Summary: Legumes control their nodule numbers through autoregulation of nodulation, with shoot perception of rhizobia-induced CLE peptides suppressing miR2111 expression and inhibiting nodule organogenesis. The shoot-derived miR2111 is a critical factor positively regulating root nodule development and influencing root system architecture.

Summary: Plants face unfavorable conditions and microbial pathogens that can cause damage to their growth and survival. Maintaining a healthy and stress-free host plant is crucial for a successful symbiotic relationship with rhizobia. The rhizobia not only assist with nitrogen fixation but also enhance the plant's defense mechanisms against stress and provide disease protection.

Summary: In this study, the researchers investigated the role of the rice AGO1d protein in phasiRNA biogenesis and function. They found that AGO1d is specifically expressed in anther wall cells and associates with miR2118 and miR2275 to mediate phasiRNA production. Depletion of AGO1d resulted in a reduction of phasiRNAs and temperature-sensitive male sterility in rice. These findings highlight the essential role of AGO1d in anther development and demonstrate the coordination of AGO proteins in reproductive phasiRNA processes.

Summary: The phased, small interfering RNAs (phasiRNAs) enriched in anthers play essential roles in maintaining male fertility in grass species. This study identified coexpression networks associated with anther development in maize and found two modules highly enriched for the phasiRNA loci. It revealed the timing of transcription factors (TFs) in phasiRNA biogenesis and showed that certain TFs can activate phasiRNA pathway genes but not specific PHAS loci.

Summary: Plant miRNAs are small noncoding RNA molecules that regulate gene expression and play important roles in development, growth, and stress responses. Accurately identifying miRNAs in plant populations is challenging but crucial. In this study, we present miRador, a fast and accurate tool for miRNA identification in plants, which outperforms other commonly used prediction tools. miRador utilizes the most up-to-date criteria for miRNA annotation and combines target prediction and PARE data for improved precision. This tool will be valuable for the plant community in identifying and annotating miRNAs in plant genomes.

Summary: Plastid-expressed double-strand RNA can escape the organelle and trigger gene silencing in the nucleus through phasiRNA biogenesis. This study demonstrates that plastid-encoded transgenes affect nuclear gene silencing, providing evidence for RNA escape from plastids. Furthermore, this research opens up new possibilities for studying plastid development and small RNA biogenesis.

Summary: In this study, a QTL associated with BPH resistance at the early seedling stage was identified on chromosome 3 using QTL-seq analysis. Bph14 was identified as a potential candidate gene based on gene expression and sequence variation differences compared with the parents. This functional gene of Bph14 from RH is important for BPH resistance at the early seedling stage and could be used in breeding programs to enhance BPH resistance in rice at both early and later growth stages.

Summary: Hybrid breeding has been used to increase agricultural outputs without higher inputs. However, soybean has been limited in exploiting hybrid vigor due to self-pollination. This study demonstrates the successful use of the barnase/barstar system to produce hybrid seeds in soybean and rescue male fertility. Importantly, the dosage of barnase and barstar is critical in achieving successful rescue.
