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 کاملMolecular markers for leaf rust resistance genes in wheat.
Over 100 genes of resistance to rust fungi: Puccinia recondita f. sp. tritici, (47 Lr - leaf rust genes), P. striiformis (18 Yr - yellow rust genes) and P. graminis f. sp. tritici (41 Sr - stripe rust genes) have been identified in wheat (Triticum aestivum L.) and its wild relatives according to recent papers. Sixteen Lr resistance genes have been mapped using restriction fragments length polym...
متن کاملMolecular Markers in Wheat
The progress made in DNA markers technology has been tremendous and exciting. DNA markers have provided valuable tools in various analysis ranging from polygenetic analysis to the positional cloning of genes. The development of high density molecular maps which has been facilitated by the PCR-based markers have made the mapping of almost any trait possible. The size and structure of the wheat g...
متن کاملGenetic Diversity of Bread Wheat (Triticum aestivum L.) Genotypes Using RAPD and ISSR Molecular Markers
The importance of grain cultivation especially wheat is obvious in terms of providing human and animal food and its impact on the economy of human societies. The reduction of genetic diversity in cultivars prevents increasing yields in line with rising demand and consumption. Therefore, it is necessary to improve the compatibility of them and increase their genetic extent. In the current, the g...
متن کاملEffect of Reduced Height Genes (Rht) on Components of the Root System in Bread Wheat
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...
