Chemico-Genetic Bases for the Reserve Carbohydrates in Maize Endosperm.
H E relationships between genes and metabolic processes have received T increasing attention in recent years. Morphological studies have been supplemented by chemical and biochemical investigations which attempt to discover the physiological bases of gene action. Examples include the findings on genetic control of the flower pigments in Primula, Dahlia, etc. (summarized by SCOTT-MONCRIEFP, 1936...
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 کاملProspects for reducing fumonisin contamination of maize through genetic modification.
Fumonisins (FB) are mycotoxins found in (italic)Fusarium verticillioides-infected maize grain worldwide. Attention has focused on FBs because of their widespread occurrence, acute toxicity to certain livestock, and their potential carcinogenicity. FBs are present at low levels in most field-grown maize but may spike to high levels depending on both the environment and genetics of the host plant...
متن کاملγ-Zeins are essential for endosperm modification in quality protein maize
Zeins are essential for endosperm modification in quality protein maize" Essential amino acids like lysine and tryptophan are deficient in corn meal because of the abundance of zein storage proteins that lack these amino acids. A natural mutant, opaque 2 (o2) causes reduction of zeins, an increase of nonzein proteins, and as a consequence, a doubling of lysine levels. However, o2's soft inferio...
متن کاملGamma-zeins are essential for endosperm modification in quality protein maize.
Essential amino acids like lysine and tryptophan are deficient in corn meal because of the abundance of zein storage proteins that lack these amino acids. A natural mutant, opaque 2 (o2) causes reduction of zeins, an increase of nonzein proteins, and as a consequence, a doubling of lysine levels. However, o2's soft inferior kernels precluded its commercial use. Breeders subsequently overcame ke...
