Fragrance in Pandanus amaryllifoliusRoxb. Despite the Presence of a Betaine Aldehyde Dehydrogenase 2.

ABSTRACT: Pandanus amaryllifoliusRoxb. accumulates the highest concentration of the major basmati aroma volatile 2-acetyl-1-pyrroline (2AP) in the plant kingdom. The expression of 2AP is correlated with the presence of a nonfunctional betaine aldehyde dehydrogenase 2(BADH2) in aromatic rice and other plant species. In the present study, a full-length BADH2 sequence was reconstructed from the transcriptome data of leaf tissue from P. amaryllifolius seedlings. Based on this sequence, a 1509 bp coding sequence was defined that encoded a 54 kD PaBADH2protein. This revealed the presence of a full-length BADH2 protein in P. amaryllifolius. Moreover, quantitative real-time PCR analysis, combined with BADH2 enzyme activity, confirmed the expression and functionality of the
