Abstract
The consumption of food-derived products, including the regular intake of pepper, is increasingly evaluated for its potential benefits in protecting against diverse metabolic complications. The current study made use of prominent electronic databases including PubMed, Google Scholar, and Scopus to retrieve clinical evidence linking the intake of black and red pepper with the amelioration of metabolic complications. The findings summarize evidence supporting the beneficial effects of black pepper (Piper nigrum L.), including its active ingredient, piperine, in improving blood lipid profiles, including reducing circulating levels of total cholesterol, low-density lipoprotein cholesterol, and triglycerides in overweight and obese individuals. The intake of piperine was also linked with enhanced antioxidant and anti-inflammatory properties by increasing serum levels of superoxide dismutase while reducing those of malonaldehyde and C-reactive protein in individuals with metabolic syndrome. Evidence summarized in the current review also indicates that red pepper (Capsicum annum), together with its active ingredient, capsaicin, could promote energy expenditure, including limiting energy intake, which is likely to contribute to reduced fat mass in overweight and obese individuals. Emerging clinical evidence also indicates that pepper may be beneficial in alleviating complications linked with other chronic conditions, including osteoarthritis, oropharyngeal dysphagia, digestion, hemodialysis, and neuromuscular fatigue. Notably, the beneficial effects of pepper or its active ingredients appear to be more pronounced when used in combination with other bioactive compounds. The current review also covers essential information on the metabolism and bioavailability profiles of both pepper species and their main active ingredients, which are all necessary to understand their potential beneficial effects against metabolic diseases.

Abstract
Capsaicinoids are responsible for the pungent flavor of peppers (Capsicum sp.). The cultivar CH-19 Sweet is a non-pungent pepper mutant that biosynthesizes the low-pungent capsaicinoid analogs, capsinoids. Capsinoids possess important pharmaceutical properties. However, capsinoid concentrations are very low in CH-19 Sweet, and Capsicum cultivars with high content capsinoids are desirable for industrial applications of capsinoids. Habanero, Bhut Jolokia, and Infinity are species of Capsicum chinense, and have strong pungency and intense fruity flavors. In the present study, we report new cultivars with high concentrations of capsinoids (more than ten-fold higher than in CH-19 Sweet), and showed that these cultivars (Dieta0011-0301 and Dieta0011-0602 from Bhut Jolokia, Dieta0041-0401 and Dieta0041-0601 from Infinity) are of nutritional and medicinal value and have fruity aromas. We also obtained a vanilla bean flavor, vanillyl alcohol, and vanillyl ethyl ether from capsinoids in the fruit of these cultivars following the addition of ethanol at room temperature.

Positional differences of intronic transposons in pAMT affect the pungency level in chili pepper through altered splicing efficiency. Plant J 2019; 100:693-705.

Abstract
Capsaicinoids are unique compounds that give chili pepper fruits their pungent taste. Capsaicinoid levels vary widely among pungent cultivars, which range from low pungency to extremely pungent. However, the molecular mechanisms underlying this quantitative variation have not been elucidated. Our previous study identified various loss-of-function alleles of the pAMT gene which led to low pungency. The mutations in these alleles are commonly defined by Tcc transposon insertion and its footprint. In this study, we identified two leaky pamt alleles (pamtL1 and pamtL2 ) with different levels of putative aminotransferase (pAMT) activity. Notably, both alleles had a Tcc transposon insertion in intron 3, but the locations of the insertions within the intron were different. Genetic analysis revealed that pamtL1 , pamtL2 and a loss-of-function pamt allele reduced capsaicinoid levels to about 50%, 10% and less than 1%, respectively. pamtL1 and pamtL2 encoded functional pAMT proteins, but they exhibited lower transcript levels than the functional type. RNA sequencing analysis showed that intronic transposons disrupted splicing in intron 3, which resulted in simultaneous expression of functional pAMT mRNA and non-functional splice variants containing partial sequences of Tcc. The non-functional splice variants were more dominant in pamtL2 than in pamtL1 . This suggested that the difference in position of the intronic transposons could alter splicing efficiency, leading to different pAMT activities and reducing capsaicinoid content to different levels. Our results provide a striking example of allelic variations caused by intronic transposons; these variations contribute to quantitative differences in secondary metabolite contents.
