“…Even within the same variety, nutritional composition of peppers varies depending on developmental stages, growing regions, and agricultural practices [10][11][12][13][14]. Pérez-López et al [14] showed that levels of ascorbic acid, total carotenoid, phenolic, and mineral were affected by the fruit maturation and types of agricultural practice.…”

Red peppers are a remarkable source of nutrients in the human diet. However, comprehensive studies have not reported on the effects of genotype, cultivation region, and year on pepper fruit characteristics. To address this, 12 commercial pepper varieties were grown at two locations in South Korea, during 2016 and 2017, representing four environments, and concentrations of proximate, minerals, amino acids, fatty acids, capsaicinoids, and free sugars in pepper pericarps were determined. Variation in most nutrients was observed among the 12 varieties grown within each location in each year, indicating a significant genotype effect. Statistical analysis of combined data showed significant differences among varieties, locations, and years for the measured components. The % variability analysis demonstrated that environment (location and year) and genotype-environment interaction contributed more to the nutritional contents than genotype alone. Particularly, variation in many amino acids, capsaicinoids, free sugars, and myristic acid was attributed to location. Year effect was significant for palmitoleic acid, ash, tryptophan, copper, linolenic acid, crude fiber, and tyrosine. Insoluble dietary fiber, soluble dietary fiber, sodium, sulfate, linoleic acid, and alanine were primarily varied by genotype–environment interaction. Palmitic acid was the trait the most highly affected by genotype. Cultivation and the genotype–environment interaction have a major role in determining the composition of 12 pepper varieties across four environments. The data from this study could explain the natural variation in the compositional data of peppers by genotypes and environments.

“…Seeds of Capsicum genotypes belonging to highly pungent C. chinense (Bhut Jolokia; Acc-Cc74; 925084.8 Scoville Heat Unit; SHU) and lowly pungent C. annuum (Acc-Ca18; 7034.4 SHU) were sown in agro peat and vermiculite (in the proportion 3:1; Sarpras et al, 2019). The seedlings were grown in a glasshouse at 24-26 • C temperature with 16-h light and 8-h dark photoperiod and 70% humidity.…”

Myeloblastosis (MYB) genes are important transcriptional regulators of plant growth, development, and secondary metabolic biosynthesis pathways, such as capsaicinoid biosynthesis in Capsicum. Although MYB genes have been identified in Capsicum annuum, no comprehensive study has been conducted on other Capsicum species. We identified a total of 251 and 240 MYB encoding genes in Capsicum chinense MYBs (CcMYBs) and Capsicum baccatum MYBs (CbMYBs). The observation of twenty tandem and 41 segmental duplication events indicated expansion of the MYB gene family in the C. chinense genome. Five CcMYB genes, i.e., CcMYB101, CcMYB46, CcMYB6, CcPHR8, and CcRVE5, and two CaMYBs, i.e., CaMYB3 and CaHHO1, were found within the previously reported capsaicinoid biosynthesis quantitative trait loci. Based on phylogenetic analysis with tomato MYB proteins, the Capsicum MYBs were classified into 24 subgroups supported by conserved amino acid motifs and gene structures. Also, a total of 241 CcMYBs were homologous with 225 C. annuum, 213 C. baccatum, 125 potato, 79 tomato, and 23 Arabidopsis MYBs. Synteny analysis showed that all 251 CcMYBs were collinear with C. annuum, C. baccatum, tomato, potato, and Arabidopsis MYBs spanning over 717 conserved syntenic segments. Using transcriptome data from three fruit developmental stages, a total of 54 CcMYBs and 81 CaMYBs showed significant differential expression patterns. Furthermore, the expression of 24 CcMYBs from the transcriptome data was validated by quantitative real-time (qRT) PCR analysis. Eight out of the 24 CcMYBs validated by the qRT-PCR were highly expressed in fiery hot C. chinense than in the lowly pungent C. annuum. Furthermore, the co-expression analysis revealed several MYB genes clustered with genes from the capsaicinoid, anthocyanin, phenylpropanoid, carotenoid, and flavonoids biosynthesis pathways, and related to determining fruit shape and size. The homology modeling of 126 R2R3 CcMYBs showed high similarity with that of the Arabidopsis R2R3 MYB domain template, suggesting their potential functional similarity at the proteome level. Furthermore, we have identified simple sequence repeat (SSR) motifs in the CcMYB genes, which could be used in Capsicum breeding programs. The functional roles of the identified CcMYBs could be studied further so that they can be manipulated for Capsicum trait improvement.

“…It was determined that Al, Mn and Zn had only accumulated in the tomatoes irrigated at 120%. K, Mg, P, Ca are essential macro-elements and on average an adult requires more than 100 mg/day, while Fe and Zn are the second essential trace element with adults requiring less than 100 mg/day [37].…”

The purpose of this study was to investigate the effect of deficit irrigation applications on the chemical compounds and mineral contents of tomatoes. In the study, a tomato (Solanum lycopersicum L) hybrid "Nehir F1" was grown in a greenhouse that had a natural light, heating and ventilation system and was covered with polycarbonate material. The tomatoes were irrigated every three days by applying 60% (T1), 80% (T2), 100% (T3) and 120% (T4) of the evaporation value after reading and determining it from the reduced evaporation pan. The tomatoes were harvested at the red-ripe maturity stage and analyses were performed. As a result of the study a total of 60 compounds were determined in the tomato samples by using Gas chromatography/Mass Spectrometer system. The most abundant compounds in terms of both amount and variety in the tomatoes were identified as ketones, sugars and fatty acid esters. Furthermore, the mineral content of the tomatoes changed according to the irrigation application. K, Mg, P, Ca and Fe were accumulated in the all tomatoes samples.
