In nine Bolivian purple corn ( Zea mays L.) varieties the content of phenolic compounds as well as the anthocyanin composition has been determined. The phenotypes under investigation included four red and five blue varieties (Kulli, Ayzuma, Paru, Tuimuru, Oke, Huaca Songo, Colorado, Huillcaparu, and
A maize (Zea mays L. subsp. mays) diversity panel consisting of 26 maize lines exhibiting a wide range of cell-wall properties and responses to hydrolysis by cellulolytic enzymes was employed to investigate the relationship between cell-wall properties, cell-wall responses to mild NaOH
Abscisic acid (ABA)-induced increase in stomatal diffusive resistance (SDR) in excised leaves of bean (Phaseolus vulgaris L. cv Pencil Pod) and maize (Zea mays L. cv Golden Bantam) is inhibited by low concentrations of trans-cinnamic acid (TCA) (1 micromolar) and p-coumaric acid (PCA) (10
A glutathione S-transferase (GST) enzyme from corn (Zea mays L. Pioneer hybrid 3906) that is active with p-coumaric acid and other unsaturated phenylpropanoids was purified approximately 97-fold and characterized. The native enzyme appeared to be a monomer with a molecular mass of approximately 30
The kernel pericarp of a maize (Zea mays L.) inbred, Mp313E, that browns rapidly at milk stage when damaged and that is resistant toAspergillus flavus Link and the dusky sap beetleCarpophilus lugubris Murray compared to a susceptible inbred, SC212M, was examined for differing oxidizing enzymes
Hydroxycinnamic acids, including ferulic acid and p-coumaric acid, have been tied to multiple positive health and agronomic benefits. However, little work has been done to improve the concentration of hydroxycinnamic acids in maize. We evaluated a set of twelve commercially important maize (Zea mays
Many leaf characteristics vary with position along the culm in maize (Zea mays L.) due to the existence of vegetative phase change and heteroblasty. The objective of this work was to determine if differences in cell wall composition exist among developmental phases and between Cg1, a developmental
One of the challenges to enable targeted modification of lignocellulosic biomass from grasses for improved biofuel and biochemical production lies within our limited understanding of the transcriptional control of secondary cell wall biosynthesis. Here, we investigated the role of the maize MYB
BACKGROUND
Total polyphenolic extracts from red wine protect against azoxymethane (AOM)-induced colon carcinogenesis in rats. Since red wine contains more than 200 different polyphenolic compounds, it is still unclear which substances are responsible for this effect.
OBJECTIVE
We investigated the
Thirty-three Chilean corn accessions were screened for the first time regarding their phenolic profiles, total phenolic contents (TPC), antioxidant capacity (DPPH and ABTS), and in vitro inhibition against key enzymes relevant for hyperglycemia (α-amylase and α-glucosidase) and hypertension
Peruvian corn biodiversity is one of the highest in the world and may represent an important natural source of health relevant phenolic bioactive compounds whose potential needs to be investigated. This study investigated twenty-two Peruvian corn samples corresponding to five corn races (Arequipeño,
Maize is an important grain crop in the United States and worldwide. However, maize grain must be processed prior to human consumption. Furthermore, whole grain composition and processing characteristics vary among maize hybrids and can impact the quality of the final processed product. Therefore,
Beneficial effects on overall gut health by phenolic bioactives-rich foods are potentially due to their modulation of probiotic gut bacteria and antimicrobial activity against pathogenic bacteria. Based on this rationale, the effect of the free and bound phenolic fractions from a Peruvian purple
Stalk lodging in maize (Zea mays) causes significant yield losses due to breaking of stalk tissue below the ear node before harvest. Here, we identified the maize (Zea mays) brittle stalk4 (bk4) mutant in a Mutator F2 population. This mutant was characterized by highly brittle aerial parts that
We have investigated the impact of the brown-midrib bm5 mutation on lignins and on p-coumaric acid and ferulic acid ester-linked to maize (Zea mays L.) cell walls. Lignified stalks or plant aerial parts (without ears) collected at grain maturity were studied in three genetic backgrounds. Relative to
