CRISPR/Cas9-Mediated Targeted Mutagenesis of Betaine Aldehyde Dehydrogenase 2 (BADH2) in Tobacco Affects 2-Acetyl-1-pyrroline

et al.

Abstract: 2-acetyl-1-pyrroline (2AP) is a highly effective volatile compound that gives fragrance to numerous plant species and food. Mutation(s) in the betaine aldehyde dehydrogenase 2 (BADH2) gene results in the accumulation of 2AP. However, the function of BADH genes in tobacco (Nicotiana tabacum L.) remains poorly understood. In this study, we successfully obtained four betaine aldehyde dehydrogenase (BADH) genes from tobacco. Phylogenetic analysis of the protein sequences showed that two of the four BADH genes were… Show more
