Among plant metabolites, phenolamides, which are conjugates of hydroxycinnamic acid derivatives and polyamines, play important roles in adaptation to abiotic biotic stresses. However, the molecular mechanisms underlying phenolamide metabolism regulation as well effects domestication breeding on diversity tomato remain largely unclear. In this study, we performed a metabolite-based genome-wide association study identified two biosynthetic gene clusters (BGC7 BGC11) containing 12 genes...
ABSTRACT The structural and functional diversity of plant metabolites is largely created via chemical modification a basic backbone. However, metabolite modifications in plants have still not been thoroughly investigated by metabolomics approaches. In this study, widely targeted modificomics (WTMM) strategy was developed based on ultra‐high performance liquid chromatography‐quadrupole‐linear ion trap (UHPLC‐Q‐Trap) UHPLC‐Q‐Exactive‐Orbitrap (UHPLC‐QE‐Orbitrap), which greatly improved the...
Perchlorate and chlorate are ubiquitous pollutants in various types of foodstuffs, drinking water environmental compartments. They have raised great concerns due to potential adverse effects on human thyroid functions. Dietary intake is considered as the predominant pathway for exposure perchlorate chlorate. Nevertheless, data chemicals above remain limited, particularly most vulnerable populations such infants. In present study, 62 breast milks, 53 infant formulas, 88 baby supplementary...
Areca catechu L., of the Arecaceae family, is widely distributed in tropical Asia. In A. catechu, extracts and compounds, including flavonoids, have various pharmacological activities. Although there are many studies molecular mechanism their biosynthesis regulation remains unclear catechu. this study, 331 metabolites were identified from root, stem, leaf using untargeted metabolomics, 107 71 lipids, 44 amino acids derivatives, 33 alkaloids. The transcriptome analysis 6119 differentially...
Volatile accumulation during tomato ripening greatly affects the fruit flavor. In this study, four accessions from each of three subgroups (BIG, S. lycopersicum, CER, lycopersicumvar. Cerasiforme, and PIM, pimpinellifolium) were subjected to a sensory evaluation. The CER subgroup had highest fruit-flavor score. Using Headspace solid-phase microextraction/gas chromatography-mass spectrometer (HP-SPME/GC-MS), volatile database containing 94 volatiles was created. Pentanal accumulated in green...
UV-B, an important environmental factor, has been shown to affect the yield and quality of rice (Oryza sativa) worldwide. However, molecular mechanisms underlying response UV-B stress remain elusive in rice.
To address the growing size of AI model training data and lack a universal selection methodology-factors that significantly drive up costs -- this paper presents General Information Metrics Evaluation (GIME) method. GIME leverages general information metrics from Objective Theory (OIT), including volume, delay, scope, granularity, variety, duration, sampling rate, aggregation, coverage, distortion, mismatch to optimize dataset for purposes. Comprehensive experiments conducted across diverse...
ABSTRACT Plants have evolved a sophisticated chemical defense network to counteract pathogens, with phenolamides and salicylic acid (SA) playing pivotal roles in the immune response. However, synergistic regulatory mechanisms of their biosynthesis remain be explored. Here, we identified biosynthetic gene cluster on chromosome 2 (BGC2) associated phenolamide SA, wherein key component SlEPS1 exhibits dual catalytic functions for synthesis SA. Overexpression BGC2 tomato enhanced resistance...
Summary Steroidal glycoalkaloids (SGAs) constitute a characteristic class of antinutritional metabolites that are found in certain Solanum species. Despite the considerable studies on SGA biosynthesis, mechanisms crosstalk between hormone signaling pathways regulate content still remain to be elucidated. Here, we performed metabolic genome‐wide association study (mGWAS) based levels and identified SlERF.H6 as negative regulator bitter‐SGA biosynthesis. repressed expression biosynthetic...
Steroidal glycoalkaloids (SGAs) are cholesterol-derived molecules that contribute to the pathogen defense in tomato but toxic and considered be antinutritional compounds humans. APETALA2/Ethylene Responsive Factor (AP2/ERF) family transcription factors (TFs) play an indispensable role various biological processes, such as plant growth development, fruit ripening, biotic abiotic stresses responses, SGA biosynthesis. In this study, we identified 176 AP2/ERF genes were domesticated or improved...
The diversity of anthocyanins is largely due to the action glycosyltransferases, which add sugar moieties anthocyanidins. Although a number glycosyltransferases have been identified glycosylate anthocyanidin in plants, enzyme that catalyzes malvidin galactosylation remains unclear. In this study, we three rice varieties with different leaf color patterns, anthocyanin accumulation and expression patterns biosynthesis genes (ABGs) explore uridine diphosphate (UDP)-glycosyltransferases (UGTs)...
Coconut is a tropical fruit whose flesh has high flavor quality and nutritional value; however, the differences between coconut varieties are still unclear. Here, volatiles non-volatiles were profiled at three ripening stages by HS-SPME/GC-MS UHPLC-MS/MS in two (Hainan Tall, HT Green Dwarf, GD). Four metabolite classes of associated with good aroma including hydrocarbons, benzenoids, alcohols esters, these generally higher GD, especially 7 9 months growth. Pathway-based metabolomics revealed...
Due to the unique structure of coconuts, their cultivation heavily relies on manual experience, making it difficult accurately and timely observe internal characteristics. This limitation severely hinders optimization coconut breeding. To address this issue, we propose a new model based improved architecture Deeplab V3+. We replace original ASPP(Atrous Spatial Pyramid Pooling) with dense atrous spatial pyramid pooling module introduce CBAM(Convolutional Block Attention Module). approach...
Coconut flesh is widely consumed in the market for its good flavor. However, a comprehensive and dynamic assessment of nutrients coconut their molecular regulatory mechanisms lacking. In this study, metabolite accumulation gene expression three representative cultivars belonging to two subspecies were investigated using ultra performance liquid chromatography/tandem mass spectrometry. A total 6101 features detected, which 52, 8, 158 identified as amino acids derivatives, polyamines, lipids,...
Abstract Branched-chain amino acids (BCAAs) are essential in tomato (Solanum lycopersicum) required for protein synthesis, which also modulate growth and abiotic stress responses. To date, little is known about their uptake transport especially under stress. Here, the acid permease 6 (SlAAP6) gene was identified as an transporter that restored mutant yeast cell on media with a variety of acids, including BCAAs. Overexpression SlAAP6 (SlAAP6-OE) raised BCAA content elevated fresh weight,...
Multimodal Magnetic Resonance Imaging (MRI) provides essential complementary information for analyzing brain tumor subregions. While methods using four common MRI modalities automatic segmentation have shown success, they often face challenges with missing due to image quality issues, inconsistent protocols, allergic reactions, or cost factors. Thus, developing a paradigm that handles is clinically valuable. A novel single-modality parallel processing network framework based on H\"older...

However, its underlying mechanism remains fully elucidated. In this paper, we tackle problem proposing novel cellular differentiation model for mouse (MESC) dynamics regulation: MESC-DRM. We employ...
Coconut is one of the largest seeded fruits in world. While its hard shell provides some protection for growth and development coconuts, it also hinders observation internal structural changes quality inspection during early seedling selection. The cultivation coconut seedlings takes about a year, several years them to grow into mature trees. Therefore, selection coconuts crucial. To address issue difficult features, we utilized CT scans non-destructive scanning obtain images at different...
