opaque-15, a maize mutation with properties of a defective opaque-2 modifier.
An opaque mutation was identified that reduces gamma-zein synthesis in maize endosperm. The mutation, opaque-15, causes a 2- to 3-fold reduction in gamma-zein mRNA and protein synthesis and reduces the proportion of the 27-kDa gamma-zein A gene transcript. Although the protein bodies in opaque-15 are similar in size and morphology compared to wild type, there are fewer of them in developing end...
متن کاملChemical composition and nutritional properties of a sugary-1/opaque-2 (su1/o2) variety of maize (Zea mays L.).
While the data of Table I11 indicate that Brazil nut protein does supplement bean protein, the quantitative estimate of the supplementation effect varies with the measure used for protein evaluation. Specifically, the amino acid scores drop faster than the protein efficiency ratios or the microbiological values, as the protein quality of the diet diminishes. A possible explanation of these diff...
متن کاملLysine-Ketoglutarate Reductase in Normal and Opaque-2 Maize Endosperms'
Lysine-ketoglutarate reductase catalyzes the first step of lysine catabolism in maize (Zea mays L.) endosperm. The enzyme condenses L-lysine and a-ketoglutarate into saccharopine using NADPH as cofactor. It is endosperm-specific and has a temporal pattern of activity, increasing with the onset of kernel development, reaching a peak 20 to 25 days after pollination, and thereafter decreasing as t...
متن کاملIncreasing Lysine Content of Waxy Maize through Introgression of Opaque-2 and Opaque-16 Genes Using Molecular Assisted and Biochemical Development
The low lysine content of waxy maize cannot meet the nutritional requirements of humans, livestock, or poultry. In the present study, the high-lysine genes o2 and o16 were backcrossed into wx lines using the maize high-lysine inbreds TAIXI19 (o2o2) and QCL3021 (o16o16) as donors and the waxy maize inbred line QCL5019 (wxwx) as a receptor. In the triple-cross F1, backcross, and inbred generation...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
