Summary: Drought is a globally environmental stress that poses risks to agricultural production. Legumes with nodules show superior drought tolerance compared to those without nodules. Through transcriptome and sRNAome sequencing, the molecular mechanism of rhizobium symbiosis impacting drought tolerance was investigated. The results revealed that seedlings with active nodules exhibited enhanced drought tolerance due to the early effects of symbiotic nitrogen fixation (SNF). miRNA and its target genes were found to play a role in improved drought tolerance. The study highlights the importance of SNF plants in drought tolerance.

Summary: This study reveals that overexpression of MtCBL13 in Arabidopsis increases sensitivity to drought stress. Transgenic plants overexpressing MtCBL13 exhibit enhanced sensitivity to mannitol and ABA treatments during seed germination and seedling stages. Furthermore, overexpression of MtCBL13 reduces drought tolerance in Arabidopsis, leading to increased oxidative damage, electrolyte leakage, lipid peroxidation, and water loss. These findings demonstrate that MtCBL13 negatively regulates drought tolerance through an ABA-dependent pathway.

Summary: This study investigated the impact of salt stress on leaf senescence in Medicago truncatula, identifying numerous senescence-associated genes (SAGs) at different time points and linking them to processes such as protein metabolism, photosynthesis, chlorophyll metabolism, and hormone signaling. Additionally, various transcription factor families, including NAC, bHLH, MYB, and ERF, were found to be associated with salt stress-induced leaf senescence, providing new insights for further genetic research and breeding in forage crops.

Summary: This study identified EF genes in Medicago truncatula and investigated the salt stress response function of MtEF1A1. The results showed that overexpression of MtEF1A1 enhanced plant resistance to salt stress and reduced oxidative stress levels. Additionally, the expression levels of stress-responsive and calcium-binding genes were upregulated in MtEF1A1-overexpressing M. truncatula.

Summary: Increasing evidence suggests that lncRNAs play a role in regulating plant tolerance to abiotic stress. This study characterized a salt stress-responsive lncRNA, MtCIR1, from M. truncatula and found that it negatively regulates salt stress response by affecting ABA metabolism and signaling during seed germination and Na+ transport under salt stress during seedling growth in Arabidopsis thaliana. These findings advance our understanding of the regulatory roles of lncRNAs in plant response to salt stress.

Summary: This study cloned a gene called MtTGA1 from Medicago truncatula and found that it was highly expressed in the root. The expression of MtTGA1 was upregulated after SA and BR treatments, but downregulated after GA and ABA treatments. Transgenic plants with MtTGA1 showed longer root lengths and increased activity of antioxidant enzymes. MtTGA1 also interacted with SPX1 protein. These findings are important for understanding the regulatory network of plant growth and development mediated by the TGA1 transcription factor family.

Summary: Prokaryotic and eukaryotic microbial symbiotic communities exist across different kingdoms, extending the host genome and aiding adaptation to changing environments. Plants and insects carry a variety of microbes on their surfaces, internally, and even within cells, with the insect gut being a selective environment. Despite their high dependence and frequent interaction, it remains uncertain how much plants and insects exchange and modify each other's microbiomes. This review focuses on herbivores that feed on plants in forest ecosystems, discussing the plant microbiome, overlap with insect microbial communities, and the effects of microbiome exchange on each host's fitness.

Summary: Salt stress response in Medicago truncatula involves differentially expressed coding and non-coding RNA, including mRNAs, lncRNAs, circRNAs, and miRNAs, which function in various pathways. The interactions between different RNAs were predicted based on the ceRNA theory, revealing insights into salt stress response in leguminous plants.

Summary: Enterobacter sp. SA187, a root endophytic bacterium, plays a crucial role in enhancing salt stress tolerance in plants by modulating the sulfur metabolic pathways. SA187 partially rescues the deficiency of sulfur metabolism components in the chloroplast, positively impacting the plant's response to salt stress.

Summary: Nutrient-poor ecosystems globally support high plant diversity, with facilitation among plants with different nutrient-acquisition strategies playing a key role in promoting co-existence. In this study, it was found that focal plants adjust their root system architecture and nutrient allocation when grown in proximity to neighbors with contrasting nutrient strategies, potentially enhancing nutrient uptake.

Summary: This study presents a simple and quick method based on spectrophotometry to measure the total dissolved organic carbon (DOC) concentration in root exudates. The method was validated using samples from different grass genotypes grown under different environmental conditions. The results showed that the method accurately measured the diverse metabolites in the exudates, but failed to predict the concentrations under micronutrient deficiency. Further studies are needed to validate the method on samples from other plant species and under different environmental stresses.

Summary: This review summarizes recent advances in understanding how plants and their associated microbiota shape rhizosphere processes. It discusses the mechanisms operating at the plant-microbe-soil interface and links this knowledge with approaches to intensify agricultural systems while reducing water, fertilizer, and pesticide use. In-depth knowledge of above and belowground plant traits can improve our understanding of processes and guide agricultural practices and plant breeding efforts.

Summary: This study assessed the response of maize plants to partial root drying under conditions of limited water supply. It found that there were distinguishable local and systemic physiological and metabolic responses to drought. The study also demonstrated that root growth was maintained through hydraulic redistribution rather than alteration of root architecture.

Summary: Ammonia oxidation is a critical process in the global nitrogen cycle, but the fundamental knowledge of its key enzyme, the copper-dependent ammonia monooxygenase, is lacking for ammonia-oxidizing archaea (AOA). This study investigates the enzyme's structure in two AOA using blue-native gel electrophoresis and proteomics. Two new protein subunits, AmoY and AmoZ, unique to AOA, were identified, and their genes are linked to other AMO subunit genes in streamlined AOA genomes. These findings provide avenues for further understanding the structure and function of this ecologically important nitrification complex.
