Functional Genomics of Maize Endosperm Maturation and Protein Quality
Quality Protein Maize (QPM) is a hard kernel variant of the high-lysine mutant, opaque2. Using γ-irradiation, we created opaque QPM variants to identify opaque-2 modifier genes and to investigate deletion mutagenesis combined with Illumina sequencing as a maize functional genomics tool. A K0326Y-QPM deletion mutant (line 107) was null for the 27and 50-kD γ-zeins and abolished vitreous endosperm...

متن کاملEndosperm Mutants of Maize
Sugar metabolism in kernels of starch-deficient endosperm mutants of maize (Zea mays L.) was examined to determine how single locus mutations of carbohydrate metabolism affect carbohydrate metabolism as a whole. Activities of 14 enyzmes were measured in extracts from endosperms from isogenic lines of normal, shrunken, shrunken-2, shrunken-4, brittle-1, and brittle-2 maize in an OH43 background....
متن کاملDescriptive statistics and correlation analysis of agronomic traits in a maize recombinant inbred line population.
Maize (Zea mays L.) is one of the most important crops in the world. In this study, 13 agronomic traits of a recombinant inbred line population that was derived from the cross between Mo17 and Huangzao4 were investigated in maize: ear diameter, ear length, ear axis diameter, ear weight, plant height, ear height, days to pollen shed (DPS), days to silking (DS), the interval between DPS and DS, 1...
متن کاملGenetic analysis of agronomic traits associated with plant architecture by QTL mapping in maize.
Maize (Zea mays L.) is one of the most important cereal crops worldwide, and increasing the grain yield and biomass has been among the most important goals of maize production. The plant architecture can determine the grain yield and biomass to some extent; however, the genetic basis of the link between the plant architecture and grain yield/biomass is unclear. In this study, an immortal F9 rec...
