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: Medicago truncatula uses LD-induced FT genes and FE homolog to regulate flowering time via a mechanism partially conserved with Arabidopsis thaliana. Despite lacking a functional MtCO-like gene, MtFE interacts with CO and NF-Y-like proteins in regulating FT expression and flowering time.

Summary: Medicago truncatula is a model system for legume plants that has a larger genome compared to the model dicot plant Arabidopsis thaliana. Our study reveals functional diversification of MtCPL4 isoforms and suggests the presence of a large number of functionally specialized CTD-phosphatase-like proteins in plants.

Summary: This study identifies ASDs as important regulators of plant responses to ABA and shows that ASDs enhance or decrease ABA sensitivity by regulating the expression of ABA response genes. ASD1/ASD3 and ASD2/ASD4 have opposite functions in this regulation.

Summary: Heavy metal toxicity can significantly impede plant growth, development, and productivity. Arbuscular mycorrhizal (AM) fungi have been found to alleviate heavy metal stress in plants, but the understanding of metal tolerance proteins (MTPs) associated with AM fungi in legumes is still limited. This study identified and characterized 50 MTP genes in Glycine max, Medicago truncatula, and Lotus japonicus using bioinformatics methods. The findings suggest that mycorrhizal symbiosis may play a role in regulating MTPs in legumes.

Summary: This study investigated the SPR1 gene family in legumes and found that it has shrunk compared to Arabidopsis thaliana. Only a few SPR1-Like (SP1L) genes were identified in Medicago truncatula and Glycine max. The SP1L genes showed similar exon-intron organizations and conserved motifs, and their promoter regions contained essential cis-elements related to growth, development, and stress. The expression analysis revealed their potential roles in plant growth, development, light response, and salt-stress response.

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 describes a high throughput phenotyping platform for testing the effects of small signaling peptides (SSP) on root uptake of multiple nutrients in plants. The results show that SSP CEP1 can enhance nitrate uptake rate in Medicago truncatula plants deprived of nitrogen. Furthermore, specific structural variants of CEP1 peptides not only enhance nitrate uptake, but also phosphate and sulfate uptake in both Medicago truncatula and Arabidopsis thaliana. Transcriptome analysis reveals that CEP1 peptides can induce the expression of several genes, including nutrient transporters and signaling pathway genes.

Summary: This study demonstrated the effectiveness of the Fe chelate [Fe(mpp)(3)] in alleviating iron deficiency chlorosis (IDC) in soybean, improving chlorophyll content, plant growth, root responses, and nutrient uptake. Additionally, [Fe(mpp)(3)] application led to increased seed yield at full maturity compared to FeEDDHA, indicating its potential as a sustainable solution for IDC in alkaline soil conditions.

Summary: Nyctinastic leaf movement, a phenomenon where many plant species open and close their leaves during the day and night, has been of great interest to scientists for centuries. A recent study on barrelclover (Medicago truncatula) revealed the molecular genetic basis for pulvinus function and the involvement of brassinosteroid (BR) in nyctinastic leaf movement. Comparisons with non-pulvinus forming species suggest that gene functions in pulvinus determination may differ among species.

Summary: The Lysin motif (LysM) is a carbohydrate-binding module found in various organisms, and the study on Arabidopsis LysM/F-box protein InLYP1 reveals its role in glycine metabolism through interaction with proteins like GLDP1 and GLDP2. InLYP1 is involved in protein degradation and can mediate the degradation of GLDP2 to facilitate glycine decarboxylation in Arabidopsis.

Summary: Nitrate is essential for plant growth, but both high and low concentrations of nitrate inhibit soybean root development compared to optimal levels. Transcriptome analysis revealed differentially expressed genes related to metabolic processes, catalytic activity, and membrane function in response to different nitrate concentrations, providing insights into the molecular mechanisms of root response.

Summary: In this study, the alfalfa WHY gene family was studied by analyzing the alfalfa genome. The results showed that there are 10 WHY genes in alfalfa, distributed on 10 chromosomes, possibly derived from segmental duplications. Based on phylogenetic analysis, the alfalfa WHY gene family can be divided into four subfamilies, and genes within the same subfamily share similar gene structures. Furthermore, cis-regulatory element analysis revealed the abundance of regulatory elements related to transcription, cell cycle, development, hormone, and stress response in the promoter sequence of the MsWHY genes. Real-time quantitative PCR demonstrated that the expression of MsWHY genes is induced by drought, salt, and methyl jasmonate.

Summary: Lignin, a major component of plant cell walls, plays a crucial role in plant defense and structural integrity. However, genetic modification of lignin biosynthesis can lead to unexpected dwarf phenotypes in plants. Various hypotheses have been proposed to explain this phenomenon, including transcriptional reprogramming and growth-defense trade-offs, but a commonly accepted mechanism is still lacking.

Summary: The study successfully overcame the ploidy barrier by using two wild peanut relatives to create a tetraploid with the same genome composition as cultivated peanut. The new allotetraploid ValSten exhibited high resistance to diseases and morphological variations in the early generation. This new germplasm provides a valuable resource for peanut research and improvement.

Summary: The mutagenic effects of ionizing radiation, especially fast neutron bombardment, have been widely used to create novel variants in experimental populations, particularly in plants. This study compared small insertions and deletions (indels) in soybean lines subjected to fast neutron irradiation with standing indels in diverse soybean lines. The results showed that fast neutron irradiation generates numerous small indels, with higher frequency of deletions that can induce frameshift mutations and impact single genes.

Summary: Biological introductions serve as unintended natural experiments and provide unique insights into evolutionary processes. Invasive phytophagous insects, in particular, are important for studying adaptation as they often need to rapidly adapt to new host plants. However, the genetic paradox of invasions poses a limitation to the adaptive potential of invasive populations due to reduced genetic diversity. One potential solution to this paradox is the existence of multiple invasive waves that increase genetic variation in invasive populations.

Summary: Cotton leaf curl virus (CLCuV) has caused significant damage to fiber production in Central Asia. The virus's spread across Asia has raised concerns that it will continue to spread before resistant varieties can be developed. By using quantitative trait loci (QTL) mapping with different sources of resistance, SNP markers associated with resistance were identified, allowing the development of resistant varieties without the need for field screening every generation.
