Plant height and heading time are important agronomic traits that significantly contribute to the improvement of wheat adaptability yield. The aim this study was evaluate level phenotypic variability these two in a collection species originating from 20 countries, analyse its molecular diversity based on microsatellite loci associated with previously mapped quantitative trait loci, estimate pot...

abstract low molecular weight carboxylic acids (lmw) play an important role in improving the bioavailability of soil nutrients. nonexchangeable soil k, trapped between the interlayers of clay minerals, is an important source of k for plants in many soils. the objectives of this study were to determine the effect of selected lmw organic acids on the release of k from micaceous minerals and to in...

The expression of a wheat genomic clone containing the entire coding sequence of the high molecular weight glutenin subunit 12 gene flanked by 2.6 kilobases of 5' and 1.5 kilobases of 3' sequences has been studied after introduction into tobacco. Seeds of different tobacco plants containing the full-length wheat genomic clone accumulated different amounts of intact high molecular weight gluteni...

The aim of this study was to determine the effects of postexercise ingestion of different-molecular-weight glucose polymer solutions on subsequent high-intensity interval-running capacity. In a repeated-measures design, 6 men ran for 60 min in the morning at 70% VO2max. Immediately post- and at 1 and 2 hr postexercise, participants consumed a 15% low-molecular-weight (LMW) or high-molecular-wei...

Low molecular weight (LMW) IgM is the monomeric subunit of pentameric IgM. It was not found in the sera of 20 healthy subjects but was detected in all six patients with mixed cryoglobulinaemia with a mean value of 1.4 g/l, representing 34% of the total IgM. In three of four patients studied LMW IgM was monoclonal and of the same light chain type (kappa) as the pentameric monoclonal IgM rheumato...

Based on available DNA sequence data in the HLA region of 4 Mb, we review the degree of polymorphism at 39 loci of which most are involved in the immune system. The extent of nucleotide differences per silent site differs greatly from locus to locus. It is exceptionally high at classical MHC loci, intermediate at six MHC-related pseudogenes as well as at some loci in class I and II regions, and...
