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 کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولAn improved genetic model generates high-resolution mapping of QTL for protein quality in maize endosperm.
The genetic mapping of polymorphic markers in a cross between two inbred plant lines has proven to be a powerful method for detecting quantitative trait loci (QTL) underlying complex traits. However, existing methods of QTL mapping were developed for disomic inheritance of both marker and QTL loci in a diploid population. To map QTL influencing traits expressed in the endosperm, a triploid embr...
متن کاملPloidy barrier to endosperm development in maize.
Maize kernels inheriting the indeterminate gametophyte mutant (ig) on the female side had endosperms that ranged in ploidy level from diploid (2x) to nonaploid (9x). In crosses with diploid males, only kernels of the triploid endosperm class developed normally. Kernels of the tetraploid endosperm class were half-sized but with well-developed embryos that regularly germinated. Kernels of endospe...
