Dee-Gee-Woo-Gen is the source of dwarfing gene in Rice.
Analysis of the genetic lineage of the majority of the cultivated rice varieties in tropical Asia reveals that sd1 from DGWG (Dee-Gee-Woo-Gen) is the major source of dwarfing gene.
The high amount of genetic homogeneity renders rice plants vulnerable to the epidemic of diseases and insect pests. The phenotype of sd-1 is consistent with dwarfism that results from a deficiency in gibberellin (GA) plant growth hormones.
