“…Our results demonstrated that changes in the Cu concentrations used to irrigate tomato plants, and previously established in the laboratory to generate Cu sufficiency and deficiency-growing conditions (Romero et al, 2021), implied changes in fruit Cu content (Fig. 1A and B).…”

“…No CuSO 4 was added to generate Cu deficiency in the second set (-Cu). The 5 µM CuSO 4 concentration was previously established in the laboratory as the optimal Cu concentration for plant vigour and development in this cultivar (Romero et al, 2021). Plants were allowed to grow and, daily, the flowers were tagged at bloom.…”

“…Furthermore, all the SlCOPTs contained several Cu-responsive elements ( CuRE, GTAC motif ) and different types of cis -elements related to hormone response, in which those related to ABA predominated. The responsive elements associated with ABA, cytokinins, GA, and auxin were found in all the SlCOPT members ( Romero et al., 2021 ), indicating the induction of SlCOPT under the control of Cu and hormonal signaling.…”

Molecular mechanism of Cu metal and drought stress resistance triggered by Porostereum spadiceum AGH786 in Solanum lycopersicum L.

Rapid industrialization and global warming have threatened the plants with multiple abiotic stresses, such as heavy metals and drought stress. For crop cultivation, the conventional approach of cleaning the soils by excavation is very costly and not feasible for large scale. Establishing toxin-free and drought-resistant crops is a major challenge in the environment under natural and anthropogenic pressure. In the past decades, copper contamination of agricultural land has become an emerging concern. For dry land reclamation, several new strategies, including bioremediation (phytoremediation and microbial remediation), have been used. Owing to the potential of Cu hyperaccumulators, the current project aims to enhance the drought tolerance and the phytoremediation potential of Solanum lycopersicum L. with the inoculation of copper and 12% polyethylene glycol (PEG)–induced drought stress–tolerant endophytic fungus Porostereum spadiceum AGH786 under the combined stress of copper heavy metal and PEG-induced drought stress. When S. lycopersicum L. was watered with individual stress of copper (Cu) concentration (400 ppm) in the form of copper sulfate (CuSO4.5H2O), 12% PEG–induced drought stress and the combined stress of both negatively affected the growth attributes, hormonal, metabolic, and antioxidant potential, compared with control. However, the multistress-resistant AGH786 endophytic fungus ameliorated the multistress tolerance response in S. lycopersicum L. by positively affecting the growth attributes, hormonal, metabolic, and antioxidant potential, and by restricting the root-to-shoot translocation of Cu and inducing its sequestration in the root tissues of affected plants. AGH786-associated plants exhibited a reduction in the severity of copper (Cu) and drought stress, with higher levels of SlCOPT (Cu transporters) and SlMT (metallothionine) gene expressions in root and shoot tissues, indicating that AGH786 contributed to resistance to copper metal toxicity and drought stress in the host S. lycopersicum L.

“…The changes in these two genes indicated that they play the same roles with AtPAA2 and AtCCS . In contrast, the expression level of SlCOPT1, which shows high similarity with AtCOPT2 [ 138 ], was significantly upregulated in RDFR than in WHFR. Although AtCOPT2 regulates Cu transport, the COPT transcript level is also inhibited by high Cu levels [ 136 , 139 ].…”

Light quality affects plant growth and the functional component accumulation of fruits. However, there is little knowledge of the effects of light quality based on multiomics profiles. This study combined transcriptomic, ionomic, and metabolomic analyses to elucidate the effects of light quality on metabolism and gene expression in tomato fruit. Micro-Tom plants were grown under blue or red light-emitting diode light for 16 h daily after anthesis. White fluorescent light was used as a reference. The metabolite and element concentrations and the expression of genes markedly changed in response to blue and red light. Based on the metabolomic analysis, amino acid metabolism and secondary metabolite biosynthesis were active in blue light treatment. According to transcriptomic analysis, differentially expressed genes in blue and red light treatments were enriched in the pathways of secondary metabolite biosynthesis, carbon fixation, and glycine, serine, and threonine metabolism, supporting the results of the metabolomic analysis. Ionomic analysis indicated that the element levels in fruits were more susceptible to changes in light quality than in leaves. The concentration of some ions containing Fe in fruits increased under red light compared to under blue light. The altered expression level of genes encoding metal ion-binding proteins, metal tolerance proteins, and metal transporters in response to blue and red light in the transcriptomic analysis contributes to changes in the ionomic profiles of tomato fruit.
