Drought is a major limiting factor for plant survival and crop productivity. Stylosanthes angustifolia, pioneer plant, exhibits remarkable drought tolerance, yet the molecular mechanisms driving its resistance remain largely unexplored. We present chromosome-scale reference genome of S. which provides insights into evolution tolerance mechanisms. The assembled 645.88 Mb in size, containing 319.98 repetitive sequences 36,857 protein-coding genes. high quality this assembly demonstrated by presence 99.26% BUSCO 19.49 long terminal repeat index. Evolutionary analyses revealed that angustifolia shares whole-genome duplication (WGD) event with other legumes but lacks recent WGD. Additionally, has undergone gene expansion through tandem approximately 12.31 million years ago. Through integrative multiomics analyses, we identified 4 families-namely, xanthoxin dehydrogenase, 2-hydroxyisoflavanone dehydratase, patatin-related phospholipase A, stachyose synthetase-that underwent were significantly upregulated under stress. These families contribute to biosynthesis abscisic acid, genistein, daidzein, jasmonic stachyose, thereby enhancing tolerance. represents significant advancement understanding genetic underlying species. This genomic resource critical offers valuable information breeding programs aimed at improving crops.

Plant–soil feedback (PSF) was initially developed in the field of agricultural practices. In recent years, PSF has been extended to various ecosystems. Root exudates, essential for exchange materials, energy, and information at plant–soil interface, significantly influence PSF. However, how is driven by root secretions role these different pathways still needs be further explored, particularly forest Soil nutrients, microbial communities, nematodes are important research topics process exudates. Investigating aspects exudates provides valuable insights into complex interactions both above ground below surface. This can offer theoretical support guidance building stable, healthy, sustainable ecosystems future.

Stylo (Stylosanthes guianensis) exhibits excellent tolerance to low-phosphate (Pi) availability, but the underlying mechanisms responsible for improving phosphorus (P) utilization efficiency (PUE) remain unclear. This study employed metabolomics, lipidomics, and gene expression analyses investigate differential responses low-Pi stress between high-PUE genotype CF047827 cultivar Reyan No. 2. Results showed that had higher levels of membrane lipid remodeling-related genes in its leaves compared 2 under conditions. was accompanied by greater phospholipid degradation non-P-containing biosynthesis CF047827. Furthermore, purple acid phosphatase SgPAP27a, which is more highly expressed than conditions, identified functionally characterized. Its role promoting enhancing PUE confirmed through heterologous Arabidopsis. These findings provide insights identify potential candidate breeding crop cultivars.

The seed-coat color and seed size have an impact on both the evolutionary fitness grain yield of crops. Soybean is a major oil crop, exhibit natural diversity among different soybean varieties. Here, we found R2R3-MYB transcription factor GmMYB62, which shows significant increase in expression as changes from yellow to black GmMYB62 was specifically highly expressed reproductive organs, especially floral organs soybeans. encodes nuclear protein that contains two MYB domains. In phylogenetic analysis, relatively conserved after divergence monocots dicots, it also grouped with transcriptional repressors MYBs anthocyanin synthesis. overexpressed Arabidopsis seeds displayed pale-brown coat overexpression lines, contrast dark-brown observed wild-type Col-0. content lines dramatically reduced when compared Additionally, showed shorter lengths, larger widths, lower thousand-seed weights than those Furthermore, genes related synthesis regulation were investigated, eight involved pathway, like chalcone synthase (CHS), isomerase (CHI), flavanone 3-hydroxylase (F3H), anthocyanidin (ANS) severely inhibited addition, ARGOS-LIKE (ARL), B-Type Cyclin 1 (CYCB1), enhancer DA1-1 (EOD3), govern cell expansion proliferation, Overall, this study sheds new light control by provides potentially valuable targets for improving crop quality.

Abstract Phosphorus (P) deficiency alters the root morphological and physiological traits of plants. This study investigates how soybean cultivars with varying low‐P tolerance values respond to different P levels in hydroponic culture by assessing alterations length, acid phosphatase activity, organic exudation, metabolites exudates. Three low‐P‐tolerant (‘Maetsue,’ ‘Kurotome,’ ‘Fukuyutaka’) three low‐P‐sensitive (‘Ihhon,’ ‘Chizuka,’ ‘Komuta’) were grown under 0 (P0) 258 μM (P8) for 7 14 days after transplantation (DAT). Low‐P‐tolerant increased length 31% 119%, which was lower than 62% 144% increases sensitive P0 compared P8 at DAT, respectively. Acid activity exceeded that 5.2‐fold 2.0‐fold DAT. Root exudates from each cultivar revealed 177 metabolites, higher exudation P0. concentrations specific (oxalate, GABA, quinate, citrate, AMP, 4‐pyridoxate, CMP), distinguishing them The top five metabolomic pathways (purine metabolism, arginine proline TCA cycle, glyoxylate dicarboxylate alanine, aspartate, glutamate metabolism) more pronounced These findings indicate increasing not an adaptation strategy deficiency; instead, tolerant exhibit enhanced traits, including metabolite release, accelerated metabolic deficiency.

The low availability of phosphorus has become a common problem worldwide. Phosphorus is essential for phenotypic morphology and ginsenoside synthesis. However, the effects Pi stress on ginseng phenotype synthesis remain unclear. Phenotypic analyses transcriptomics revealed construction regulation differential genes involved in physiological metabolism under low-Pi stress. Root length stem were found to be significantly inhibited by phosphate-deficiency half-phosphate (HP) no-phosphate (NP) treatment groups; however, number fibrous roots, which are regulated phytohormones, was increase. In leaves, indexes stress, superoxide anion (221.19 nmol/g) malonaldehyde (MDA) (0.05 μmol/min/g), reached maximum level. Moreover, chlorophyll fluorescence images content further confirmed inhibition photosynthesis A total 579 210 differentially expressed (DEGs) shared between NP phosphate (TP) HP TP, respectively, only 64 DEGs based two comparisons. These mainly related transporters (PHTs), ginsenosides. According KEGG analyses, four (Pg_s 0368.2, Pg_s3418.1, Pg_s5392.5 Pg_s3342.1) affected acetyl-CoA production regulating glycometabolism tricarboxylic acid cycle (TCA). addition, genes, including those encoding 13 PHTs, 15 20 synthetases, screened roots Pi-deficiency results indicate that changes transcriptional environment ginseng, thereby providing new information regarding development tolerance.
