| Comment | sk1 also called as fgr is linked to one of the most important traits in rice, i.e. fragrance. This trait has undergone human selection during domestication. The fragrance of basmati and jasmine rice is associated with the presence of 2-acetyl-1-pyrroline. The sk1 encodes for betaine aldehyde dehydrogenase (BAD). Compared to the non-fragrant genotypes, the accumulation of 2-acetyl-1-pyrroline in fragrant rice genotypes is due to the loss of BAD activity. The allele in fragrant genotypes has a mutation introducing a stop codon upstream of key amino acid sequences conserved in other BADs. Another fragrance related gene called BAD1 is present on chromosome 4. The loss of function of SK1 does not affect the growth of fragrant rice genotypes. Nipponbare is a non-fragrant rice variety. |
