Vitamaize lines (VMLs) were created by backcrossing the pigmented aleurone trait into Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) maize lines (CMLs). This study evaluates metabolic differences between the VMLs and their original CMLs. Direct infusion mass spectrometry (DIMS) analyses, carotenoid profiling, total anthocyanins content (TAC) determination, and biochemical evaluation of the quality protein maize (QPM) endosperm trait allowed a comprehensive chemical characterization of the maize lines.

Plant metabolites are the basis of human nutrition and have biological relevance in ecology. Farmers selected plants with favorable characteristics since prehistoric times and improved the cultivars, but without knowledge of underlying mechanisms. Understanding the genetic basis of metabolite production can facilitate the successful breeding of plants with augmented nutritional value.

Maize is one of the most important crops for human and animal consumption and contains a chemical arsenal essential for survival: flavonoids. Moreover, flavonoids are well known for their beneficial effects on human health. In this review, we decided to organize the information about maize flavonoids into three sections.

Consistent with their reported abundance in soils, several sensu lato strains were isolated from the rhizosphere of maize plants cultivated at different sites in central México. Comparative analysis of their 16S rRNA gene sequences permitted their separation into three distinctive clades, which were further subdivided into six other clusters by their close resemblance to (1) ; (2) , , and ; (3) ; (4) ; (5) , or (6) representative species. Direct confrontation assays revealed that these strains inhibited the growth of pathogenic f.

Corn seeds contain natural pigments and antioxidants, such as the molecular variants of flavonoids and carotenoids. The aleurone and pericarp tissues from pigmented genotypes were extracted for metabolic fingerprinting and evaluated using UV-vis and mass spectrometry (MS). MS ionomic fingerprints classified samples according to genetic background and kernel color.
