Molecular characterization of Rht-1 dwarfing genes in hexaploid wheat.
The introduction of the Reduced height (Rht)-B1b and Rht-D1b semidwarfing genes led to impressive increases in wheat (Triticum aestivum) yields during the Green Revolution. The reduction in stem elongation in varieties containing these alleles is caused by a limited response to the phytohormone gibberellin (GA), resulting in improved resistance to stem lodging and yield benefits through an incr...
متن کاملChromosomal location of genes controlling flavonoid production in hexaploid wheat.
Two-dimensional paper chromatography was performed on methanol extracts of leaves of hexaploid bread wheat, Triticum aestivum L. em. Thell. cultivar Chinese Spring, and of the available nullisomic-tetrasomic compensating lines, the tetrasomic lines and the ditelocentric lines. The chromatograms had 27 spots identified as flavonoids and six representing phenolic acids. Some of the areas were com...
متن کاملEvidence for triplicate genes for alcohol dehydrogenase in hexaploid wheat.
The alcohol dehydrogenase zymogram phenotypes of 40 wheat strains, each possessing a distinctive chromosomal constitution, were determined. Genes involved in the production of alcohol dehydrogenase were located on the beta arm of chromosome 4A and on chromosomes 4B and 4D. The results support the hypothesis that the active alcohol dehydrogenase isozymes are dimers composed of the six possible c...
متن کاملOverexpression of Three TaEXPA1 Homoeologous Genes with Distinct Expression Divergence in Hexaploid Wheat Exhibit Functional Retention in Arabidopsis
Common wheat is a hexaploid species with most of the genes present as triplicate homoeologs. Expression divergences of homoeologs are frequently observed in wheat as well as in other polyploid plants. However, little is known about functional variances among homologous genes arising from polyploidy. Expansins play diverse roles in plant developmental processes related to the action of cell wall...
متن کاملIdentification and characterization of genes on a single subgenome in the hexaploid wheat (Triticum aestivum L.) genotype 'Chinese Spring'.
Gene loss during the formation of hexaploid bread wheat has been repeatedly reported. However, our knowledge on genome-wide analysis of the genes present on a single subgenome (SSG) in bread wheat is still limited. In this study, by analysing the 'Chinese Spring' chromosome arm shotgun sequences together with high-confidence gene models, we detected 433 genes on a SSG. Greater gene loss was obs...
