Food security is a global concern and substantial yield increases in crops are required to feed the growing world population. Mutagenesis is an important tool in crop improvement and is free of the regulatory restrictions imposed on genetically modified organisms. Targeting Induced Local Lesions in Genomes (TILLING), which combines traditional chemical(More)
Segregation Distorter (SD) is a meiotic drive system of natural occurrence. Heterozygous SD/SD+ males transmit the SD chromosome in vast excess over the normal homolog. SD chromosomes have been recovered at low frequency (1%-5%) from almost every population that has been screened for them in many places of the world. To examine whether there is SD system in(More)
The most common dwarfing genes in wheat, Rht-B1b and Rht-D1b, classified as gibberellin-insensitive (GAI) dwarfing genes due to their reduced response to exogenous GA, have been verified as encoding negative regulators of gibberellin signaling. In contrast, the response of gibberellin-responsive (GAR) dwarfing genes, such as Rht12, to exogenous GA is still(More)
