Coffee is consumed by more than 800 million people who enjoy its taste, flavor, and health benefits. A lthough consumption may be directly related to the quality of the coffee, little is known about the specific components of coffee, such as lipid content, that contribute to its quality. The most important lipids in coffee are the diterpenes kah-weol and cafestol, which are related to one another by their fragrance and importance to consumer health. In addition to having anticarcinogenic and intioxidant properties, they also are associated with increased concentrations of serum cholesterol. Diterpenes are one of the largest families of secondary metabolites in plants and originate from the isoprenoid pathway. Isoprenoids (also called terpenoids) are the most functionally and structurally diverse group of plant metabolites. They are synthesized in all organisms but are especially abundant and diverse in plants, with more than 40,000 compounds reported to date. Despit e the diversity of their function and structure, all isoprenoids are derived from the common five-carbon building unit iso-pentenyl diphosphate (IPP) and its isomer dimethyla llyl diphosphate (DMAPP). In higher plants, two independent pathways that are located in separate intracellular compart-ments are involved in the biosynthesis of IPP and DMAPP. In the cytosol, IPP is derived from the mevalonate (MVA) pathway. Within plastids, IPP is formed from pyruvate and glyceraldehyde 3-phosphate hrough the methylerythritol phosphate (MEP, or nonmevalonate) pathway. Although most of the genes that are associated with isoprenoid bio-synthesis have been identified using model plant species, there have been only a few studies of these genes in coffee plants. Moreover, little information about the specific formation of diterpenes is available. Here we describe the characterization of coffee genes involved in the metabolism of both isoprenoids and diterpenes.

Conteúdo: |
The objective of this work was to identify single-nucleotide polymorphism (SNP) markers linked with quantitative trait loci (QTLs) associated with increased contents of protein and oil in soybean. A total of 169 Brazilian soybean varieties, genotyped with 6,000 SNP markers, were evaluated. Protein and oil contents were obtained with the near-infrared reflectance method. Correlation and multiple linear regression analyses were used to identify linkage disequilibrium between SNP markers and the QTLs associated with the two characteristics. Seven QTLs were found to be associated with protein content, on six chromosomes (2, 6, 11, 12, 13, and 16), explaining 60.9% of the variation in this trait. For oil content, eight QTLs were identified on six chromosomes (1, 4, 5, 6, 17, and 19), explaining 78.3% of the variation in the trait. The correlation between the number of loci containing favorable alleles and the evaluated characteristics was 0.49 for protein content and 0.60 for oil content. The molecular markers identified are mapped in genomic regions containing QTLs previously mapped for both characteristics, which reinforces the association between these regions and the genetic control of oil and protein contents in soybean. |
