It is accepted that there is an interaction between dwarfing genes and the overall size of a plant because of the gene’s interaction with gibberellic acid pathways. The main objective of this project was to determine the effect of four stem dwarfing genes (Rht1, Rht2, Rht3 and rht) on components of the root system in near-isogenic lines of Maringa and Nainari 60. The working hypothesis was that...

The in vitro binding properties of enterotoxins of Vibrio cholerae and Escherichia coli to different pure gangliosides and related neutral glycosphin-golipids were analyzed with a sorbent assay utilizing plastic tubes to which the glycolipid substances had been coupled. It was found that the cholera toxin bound to G(M1) ganglioside better than to the other tested substances G(M3), G(M3)-NGN, G(...

85 Dominance, semidominance and recessiveness are important modes of Mendelian inheritance. 86 The phytohormone gibberellin (GA) regulates many plant growths and developmental processes. 87 The previously cloned semidominant GAI (GA-insensitive) genes Rht1 and Rht2 in wheat were 88 the basis of the 'green revolution'. However, no completely dominant GAI gene has been cloned. 89 Here, we report ...

We discuss the formation of nontopological solitons in a second-order phase transition in the early Universe. Ratios of dimensionless coupling constants in the Lagrangian determine their abundance and mass. For a large range of parameters, non-topological solitons can be cosmologically significant, contributing a significant fraction of the present mass density of the Universe. Submitted to Phy...

Long term use of sugars can induce excess caloric intake and/or obesity. To evaluate the effects of sugar intake on different regions of the hypothalamus (the brain’s control center for energy homeostasis) we first developed and then evaluated a microscope-assisted dissection method. Because of the small size of the paraventricular nucleus, we validated the samples by measuring several hormones...

BACKGROUND AND AIMS The gibberellin-insensitive Rht-B1b and Rht-D1b dwarfing genes are known to reduce the size of cells in culms, leaves and coleoptiles of wheat. Resulting leaf area development of gibberellin-insensitive wheats is poor compared to standard height (Rht-B1a and Rht-D1a) genotypes. Alternative dwarfing genes to Rht-B1b and Rht-D1b are available that reduce plant height, such as ...

Astrocytes are well known modulators of normal developmental retinal vascularization. However, relatively little is known about the role of glial cells during pathological retinal neovascularization (NV), a leading contributor to vision loss in industrialized nations. We demonstrate that the loss of astrocytes and microglia directly correlates with the development of pathological NV in a mouse ...

We unify the theory of cyclic and diagonal products of elements of matrices. We obtain some new results on diagonal similarity, diagonal equivalence, complete reducibility and total support. 1. I N T R O D U C T I O N Cyclic products of e lements of matrices have been considered by Fiedler and P tak [4]. Diagonal products were considered b y Sinkhorn and Knopp Elll.

Cell-penetrating peptides are able to transport covalently attached cargoes such as peptide or polypeptide fragments of endogenous proteins across cell membranes. Taking advantage of the cell-penetrating properties of the 16-residue fragment penetratin, we synthesized a chimeric peptide that possesses an N-terminal sequence with membrane-penetrating activity and a C-terminal sequence correspond...
