Summary: This research aimed to isolate halotolerant plant growth-promoting rhizobacteria and use them as bioinoculants to improve rice growth under salinity stress conditions. The results showed that isolates S-3, S-5, and S-6 significantly increased shoot height, root length, and plant dry weight compared to the control group. Isolates S-3 and S-5 were identified as Pseudomonas stutzeri and Klebsiella pneumoniae, and they exhibited promoting effects on rice growth under salinity stress conditions.

Summary: This study evaluated the previous incubation between BjE109 and AaAz39 and its impact on Bradyrhizobium-soybean symbiosis and plant growth. The results showed that the previous incubation improved the survival of BjE109 on soybean seeds and increased nodule number, size, biomass, and nodulation percentage. The grain yield under field conditions also significantly increased compared to single inoculation or immediate combination of both strains.

Summary: Mutualism between Synechococcus and heterotrophic bacteria can support their survival in nutrient-depleted conditions. However, exogenous nutrients can disrupt their established mutualism. Once the exogenous nutrients are exhausted, the mutualism and the health of Synechococcus can gradually be reestablished, with nitrogen fixation by associated bacteria playing a crucial role in this process.

Summary: Sugarcane is a significant crop in tropical and subtropical regions, with China commonly using large amounts of nitrogen fertilizer to increase yield, leading to environmental damage. Certain rhizosphere bacteria have been found to benefit sugarcane production, with some strains showing high nitrogenase and ACC deaminase activity. Two selected strains, Pantoea dispersa-AA7 and Enterobacter asburiae-BY4, exhibited the highest plant growth promotion and nitrogenase activity. They were found to colonize different sugarcane tissues, use various growth substrates, and tolerate stress conditions. These strains could potentially be used as biofertilizers for sugarcane to mitigate the use of nitrogen fertilizers and enhance disease management.

Summary: Symbiotic nitrogen fixation is an essential process in the nitrogen cycle and can contribute to sustainable agriculture. Recent studies have shown that non-coding RNAs (ncRNAs) play a significant role in regulating this process by controlling gene transcription and translation. These ncRNAs are involved in various aspects of nitrogen fixation, including hormone signal transduction, autoregulation of nodulation pathway, and nutrient homeostasis in nodules. Understanding the regulation of legume nodulation by ncRNAs can provide new insights for developing high-performance leguminous crops.

Summary: Realizing efficient hydrogenation of N2 molecules in the electrocatalytic nitrogen reduction reaction is crucial but rarely reported. A new study presents a highly efficient electrocatalyst with a hydrogen radical-transferring mechanism, which can greatly reduce the potential and maintain high activity and selectivity in NRR.

Summary: This study isolated and screened nitrogen-fixing bacteria from the roots and rhizosphere soil of Astragalus mongolicus. Three strains (Bacillus sp. J1, Arthrobacter sp. J2, and Bacillus sp. G4) were found to promote the growth of A. mongolicus and increase the nitrogen, phosphorus, and potassium content in plants. Mixed inoculation of these strains also increased bacterial diversity and changed the structure of the bacterial community in rhizosphere soil.

Summary: Pulses have distinct health benefits with low fat content, high protein and fiber contents. Their annual grain production reaches approximately 93,210 x 10(3) tons. The symbiosis between pulses and atmospheric N-2-fixing bacteria increases productivity and reduces the need for N fertilizers, contributing to environmental impact mitigation. Additionally, a diverse microbial community in the root region enhances plant growth promotion and stress tolerance. The identification of microbial taxa with plant growth-promoting traits and new insights into the microbiomes of pulse systems provide opportunities for developing biofertilizers and highlight the importance of microorganisms.

Summary: Synthetic biology has attracted the attention of researchers, intellectuals, think-tanks, and investors due to its potential to revolutionize biotechnology and expand into new industries. However, there are challenges related to basic information availability, the inherent mutability of cells, exaggerated claims, and the need for social science involvement. It is important for SynBio to address these issues and foster a partnership between technology and society.

Summary: We present a comprehensive study on the fixation and reductive coupling of dinitrogen with low-valent boron compounds, combining computational and experimental approaches. The results demonstrate that the selectivity of nitrogen fixation or coupling can be controlled by steric bulk or reaction conditions, enabling the synthesis of nitrogen chains as needed. Furthermore, we elucidate the electronic structure and magnetic properties of intermediates and products of the reaction using high-level computational methods.
