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: In response to colonization by rhizobia bacteria, legumes have developed a complex, long-distance signaling pathway to regulate nodulation in their roots and shoots. We measured the transcriptional response to rhizobia treatment in Medicago truncatula and used the GeneShift tool to detect temporal shifts in gene expression. This study identified known and novel genes that are dynamically regulated during early nodulation and validated the findings using an independent RNA-Seq study.

Summary: This study used genome-wide association study (GWAS) and selective genotyping analysis to decipher the genetic architecture of maize tar spot complex (TSC) resistance. A major resistance QTL was fine mapped, and candidate genes related to disease resistance were identified. This research provides valuable information for cloning the resistance gene and facilitating marker-assisted selection for improving TSC resistance.

Summary: This study identified 11 MtTPS genes in the genome of Medicago truncatula, divided into two subfamilies, and found that five of them could be induced by drought, salt or cold stresses, providing a foundation for further research on the regulatory function of TPS genes in response to abiotic stresses.

Summary: This study investigates the secondary metabolic changes in response to mercury stress in Medicago truncatula. The results suggest that the synthesis and glycosylation processes of flavonoids play important roles in the tolerance to mercury stress. The accumulation of flavonoids and specific glycosylation patterns are associated with mercury tolerance in different plant varieties.

Summary: Aphanomyces euteiches, a soil-borne oomycete pathogen, causes root rot diseases in legumes. Different pathotypes of A. euteiches show varying virulence, with secreted proteases and CAZymes being key factors. The specific secretome of A. euteiches includes small, secreted proteins without predicted functional domains, potentially influencing its preference for legumes. This study lays the foundation for further research on the interactions between A. euteiches and legumes.

Summary: The study conducted a systematic investigation of the PcG family in Medicago truncatula, identifying 64 PcG genes with uneven distribution and some genes undergoing duplication. The prediction of protein interaction network revealed that 34 MtPcG proteins exhibit protein-protein interactions, and the PcG proteins were divided into three groups and nine subgroups. The findings provide detailed insights into the PcG family in M. truncatula and offer potential for further research in legumes.

Summary: Plant epigenetic regulations play important roles in transposable element silencing, developmental processes, and responses to the environment. Specifically, DNA methylation modifications are involved in these processes. The development of root nodules, which are important for nitrogen fixation, is a complex process with various regulatory mechanisms. In this study, laser capture microdissection and RNA-sequencing techniques were used to identify genes activated in the nodule differentiation and nitrogen fixation zones. MtDME, which is upregulated in the differentiation zone, was found to be required for nodule development. Additionally, differentially methylated regions were identified in the nodule. CRISPR-Cas9 mutagenesis of MtDRM2 further demonstrated the importance of RdDM in CHH hypermethylation and nodule development. A model of DNA methylation dynamics during nodule development was proposed.

Summary: Yellow Stripe-Like (YSL) proteins, including MtSYL7, play an essential role in transition metal homeostasis in nodules. MtSYL7 is involved in transporting short peptides and contributes to maintaining metal homeostasis in root nodules, impacting nitrogen fixation and plant growth. Mutants with decreased MtYSL7 expression accumulate more copper and iron in nodules due to increased expression of iron uptake and delivery genes in roots.

Summary: Results showed that TN1.11 exhibited higher salt tolerance compared to the other lines, while TN6.18 was the most susceptible to salinity. Functional characterization of the MtERF1 gene revealed its expression mainly in roots and inducibility by NaCl and low temperature, with a greater increase in expression under salt stress in the salt-tolerant line TN1.11.

Summary: In mature symbiotic root nodules, rhizobia fix atmospheric dinitrogen to provide ammonium for plant nitrogen demand. The symbiosis is adjusted to the plant's nitrogen demand through systemic N signaling, controlling nodule development. Nodule expansion is stimulated under N deficit, while nodule senescence is activated under N satiety. Drought has a negative impact on nodules. In this study, split-root systems were used to characterize the systemic responses of symbiotic plants to localized osmotic stress. The application of PEG inhibited the symbiotic dinitrogen fixation activity of locally treated nodules, leading to nitrogen limitation. The localized PEG treatment triggered systemic signaling, stimulating nodule development and enhancing sucrose allocation. Transcriptomic reprogramming associated with PEG and N deficit signaling shared many target transcripts. These findings suggest that systemic N signaling plays a role in the adaptation of symbiotic plants to local variations in their edaphic environment.

Summary: Research on identifying signatures of selection using SNP data has proven effective, but there have been few methods designed to identify interacting alleles as targets of selective processes. This study proposes a statistical test aimed at detecting epistatic selection and uncovers evidence of gene coadaptation in both plant and human populations.

Summary: The study revealed the widespread presence of LCO structures in fungi, raising questions about how legume plants discern different types of LCO signals. Through a genome-wide association study, it was found that while both Nod-LCOs and Fung-LCOs can influence root branching, they operate through distinct molecular mechanisms, with Fung-LCOs showing lower heritability in root response.

Summary: This study used high-throughput field phenotyping and genome-wide association studies to investigate the genetic variability and water use in apple trees. The results showed large phenotypic and genetic variability in canopy surface temperature and other traits, and revealed the genetic control of these traits. Screening associated genomic regions also identified candidate genes involved in these traits, providing promising avenues for further optimizing tree architecture, light interception, and water use.
