Abstract Hydrogen sulfide (H2S) is involved in multiple processes during plant growth and development. D-cysteine desulfhydrase (DCD) can produce H2S with as the substrate; however, potential developmental roles of DCD have not been explored tomato lifecycle. In present study, SlDCD2 showed increasing expression fruit ripening. Compared control fruits, silencing by pTRV2-SlDCD2 accelerated A gene-edited mutant was constructed CRISPR/Cas9 transformation, exhibited ripening, decreased release, higher total cysteine ethylene contents, enhanced chlorophyll degradation increased carotenoid accumulation. Additionally, ripening-related genes, including NYC1, PAO, SGR1, PDS, PSY1, ACO1, ACS2, E4, CEL2, EXP dcd2 wild-type mutation induced H2O2 malondialdehyde (MDA) accumulation which led to an imbalance reactive oxygen species (ROS) metabolism. correlation analysis indicated that content strongly positively correlated carotenoids content, gene negatively content. earlier leaf senescence, may be due disturbed ROS homeostasis. short, our findings show generation reduction endogenous production causes ripening premature senescence. excessive suggesting a role modulating homeostasis biosynthesis.

Postharvest physiological deterioration (PPD) reduces the availability and economic value of fresh produces, resulting in waste agricultural products becoming a worldwide problem. Therefore, many studies have been carried out at anatomical structural, biochemical levels molecular PPD produces to seek ways manage postharvest quality produce. The cell wall is outermost structure plant as such represents first barrier prevent external microorganisms other injuries. Many on crop storage organs relate changes wall-related components. Indeed, these evidence non-negligible role ability. However, relationship between metabolism has not well summarized. In this review, we summarize structural walls different types PPD, metabolic changes, possible mechanism regulating This review provides basis for further research delaying occurrence

The tomato as a raw material for processing is globally important and pivotal in dietary agronomic research due to its nutritional, economic, health significance. This study explored the potential of machine learning (ML) predicting quality, utilizing data from 48 cultivars 28 locations Hungary over 5 seasons. It focused on °Brix, lycopene content, colour (a/b ratio) using extreme gradient boosting (XGBoost) artificial neural network (ANN) models. results revealed that XGBoost consistently outperformed ANN, achieving high accuracy °Brix (R² = 0.98, RMSE 0.07) content 0.87, 0.61), excelling prediction with R² 0.93 0.03. ANN lagged behind particularly prediction, showing negative value −0.35. Shapley additive explanation’s (SHAP) summary plot analysis indicated both models are effective tomatoes, highlighting different aspects data. SHAP highlighted models’ efficiency (especially predictions) underscored significant influence cultivar choice environmental factors like climate soil. These findings emphasize importance selecting fine-tuning appropriate ML model enhancing precision agriculture, underlining XGBoost’s superiority handling complex quality assessment.

High-temperature tolerant varieties/hybrids of tomato overcome stress-related changes due to their intrinsic cellular metabolic capabilities. We have used untargeted metabolite profiling and comparative biochemical biological analyses high temperature (HTT) hybrid VRNTH18283 sensitive (HTS) VRNTH19072 decipher altered pathways biomarker metabolites which were linked with enhanced antioxidant activity in HTT fruits. Parameters like fruit weight, yield per plant key determinants viz. total soluble sugar (TSS), titratable acidity, ascorbic acid lycopene content significantly compared HTS. Metabolomics revealed upregulated diversity extract (11453 m/z features) as 8834 features Statistical analysis 423 differentially up-regulated 410 down-regulated features. Multivariate data showed sample discrimination based on distinct phytochemical diversification. Functionally annotated enrichment including linoleic linolenic metabolism, monoterpenoids biosynthesis degradation, cutin, suberin wax biosynthesis, sphingolipids metabolism. Metabolite categorized benzamides, amino acids, sugars, nucleotides, sterols, glycosides, phenylacetaldehydes, indoles, tryptamines organic acids major compound classes. Among 22 potentially discriminatory obtained from OPLS-DA model, all prominently abundant solasodine, thiamine diphosphate, L-tryptophan, folic acid, lycopene, dihydrozeatin, myricetin, tomatidine, chlorogenic α-tocotrienol classified biomarkers correlated activity. The study that the physicochemical profile, increased compositional are liable for improved performance against negative impact comparison HTS VRNTH19072.

Abstract Most of the carbon found in fruits at harvest is imported by phloem. Imported provide material needed for accumulation sugars, organic acids, secondary compounds, addition to synthesis cell walls. The sugars during fruit development influences not only sweetness but also various parameters controlling composition (fruit “quality”). acids and sugar grape berry flesh cells a key process ripening. present review presents an update research on development, anatomical structure, acid metabolism, transporters, regulatory factors.

Although hydrogen gas (H2)-treated soil improves crop biomass, this approach appears difficult for field application due to the flammability of H2 gas. In report, we investigated whether and how applied in nanobubble water (HNW) yield quality cherry tomato (Lycopersicon esculentum var. cerasiforme) with without fertilizers. Two-year-long trials showed that compared corresponding controls, HNW fertilizers improved per plant by 39.7% 26.5% 2021 (Shanghai), respectively, 39.4% 28.2% 2023 (Nanjing), respectively. Compared surface (SW), increased available nitrogen (N), phosphorus (P), potassium (K) consumption regardless fertilizer application, which may be attributed NPK transport-related genes roots (LeAMT2, LePT2, LePT5, SlHKT1,1). Furthermore, HNW-irrigated tomatoes displayed a higher sugar–acid ratio (8.6%) lycopene content (22.3%) than SW-irrigated plants Importantly, beneficial effects on (9.1%), (31.1%), volatiles (20.0%) contents (54.3%) were stronger those achieved using alone. short, study clearly indicated HNW-supplied not only exhibited fertilization effect enhancing yield, but also fruit’s lower carbon footprint.
