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 کاملتوزیع آللی برخی از ژن های مؤثر در پاکوتاهی ارقام و لاین های گندم (Triticum aestivum L.) ایران
Decrease the plant height using the Rht genes is one of the main strategies to improve the resistance to lodging and fertilization and to increase the productivity in wheat. In Iran, like to other parts of world, these genes are entered to new introduced and released varieties. To study allelic diversity of two main dwarf genes (Rht-D1b and Rht-B1b) and their effects on morphological traits of ...

متن کاملDwarfing Genes Rht-B1b and Rht-D1b Are Associated with Both Type I FHB Susceptibility and Low Anther Extrusion in Two Bread Wheat Populations
It has been well documented that dwarfing genes Rht-B1b and Rht-D1b are associated with Type I susceptibility to Fusarium head blight (FHB) in wheat; but the underlying mechanism has not been well delineated. Anther extrusion (AE) has also been related to Type I resistance for initial FHB infection, where high AE renders FHB resistance. In this study, two doubled haploid populations were used t...
متن کاملGenetic impact of Rht dwarfing genes on grain micronutrients concentration in wheat
Wheat is a major staple food crop providing about 20% of dietary energy and proteins, and food products made of whole grain wheat are a major source of micronutrients like Zinc (Zn), Iron (Fe), Manganese (Mn), Magnesium (Mg), Vitamin B and E. Wheat provides about 40% intake of essential micronutrients by humans in the developing countries relying on wheat based diets. Varieties with genetically...
