Results showed that most tomato DNA methyltransferase and demethylase genes contained stress-related elements. The expression of <em>SlDML1</em> was significantly induced by cadmium (Cd) and sodium chloride (NaCl) stresses. <em>SlDML2</em> was more sensitive and reached its maximum value under polyethylene (PEG) stress at 24 h. The expression of <em>SlMET3L</em> was repressed to varying degrees under Cd, NaCl and PEG stresses at 48 h.

The phytohormone abscisic acid (ABA) is involved in the acquisition of cold tolerance in zucchini fruit, being the riboflavin pathway one of the most differentially induced with ABA treatment. Thus, the aim of this work was to elucidate the involvement of riboflavin in quality maintenance of zucchini fruit during postharvest cold storage. After testing different concentrations of exogenous riboflavin, 0.5 mM showed the best results. Riboflavin treatment reduced H<sub>2</sub>O<sub>2</sub> content, but the enzymatic antioxidant defense did not change significantly. This response is due to a rise of non-enzymatic antioxidant defense, by accumulating metabolites like ascorbate and carotenoids, as well as inducing phenolic metabolism. The application of this vitamin enhanced the phenolic and flavonoid content in fruit, concomitant with an induction of PAL and C4H activities and an inhibition of PPO activity. This enhancement of the phenylpropanoid pathway resulted in high vanillic acid and quercetin levels at first day of cold storage. The induction of numerous antioxidant compounds and abscisic acid by riboflavin treatment at short-term postharvest period could be responsible for the lack of chilling injuries in zucchini fruit. Therefore, riboflavin could be successfully implemented in the food industry as an alternative to physical or chemical treatments, due to it is an innocuous additive with good water solubility and low cost, as it prolongs the shelf-life of zucchini fruit and increases its nutraceutical properties.</div></div>","PeriodicalId":20234,"journal":{"name":"Plant Physiology and Biochemistry","volume":"217 ","pages":"Article 109270"},"PeriodicalIF":6.1,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of root-knot nematode (RKN), <em>Meloidogyne incognita</em>, and tomato yellow leaf curl virus (TYLCV; <em>Begomovirus coheni</em>) has been reported in most tomato cultivation areas. We investigated the interaction between RKN and TYLCV in tomato plants at phenotypic, biochemical, and gene expression levels. Several treatments were considered including mock inoculation, inoculation with TYLCV or RKN alone, simultaneous inoculation with both TYLCV and RKN, and sequential inoculations with a five-day interval. Among them, simultaneous inoculation showed the highest impact on RKN suppression compared to mock-inoculated plants. Biochemical assays in the time-point experiments demonstrated that the pick of defense capacity of plants occurs at 48- and 72-h post-inoculation. Gene expression analyses utilizing marker genes from main hormonal pathways involved in plant defense, including salicylic acid (SA), jasmonic acid (JA), and ethylene (ET), indicated that ET and SA are highly involved in the potentiation of TYLCV-induced defense against RKN. To validate the action of SA and ET in the induction of defense against RKN by TYLCV, transgenic lines deficient in SA (<em>NahG</em>) and ET (<em>ACD</em>) accumulation were co-inoculated with TYLCV and RKN.
