2008) who stated that the presence of dominant Badh2 allele encoding Betaine Aldehyde Dehydrogenase (BADH2) inhibited synthesis of 2AP, while its recessive alleles induced 2AP formation.
Badh2, encoding betaine aldehyde dehydrogenase, inhibits the biosynthesis of 2-Acetyl-1-pyrroline, a major component in rice fragrance.
The cDNA fragment Musa 26 encodes betaine aldehyde protein dehydrogenase (BADH, EC 1.

Betaine is synthesized by a two-step oxidation of choline in which mitochondrial choline oxidase first catalyzes the production of betaine aldehyde
, which is further oxidized by mitochondrial betaine aldehyde
dehydrogenase to betaine (Dragolovich, 1994).

Transformation of wheat with a gene encoding for the betaine aldehyde dehydrogenase (BADH).
The Suaeda liaotungensis kitag betaine aldehyde
dehydrogenase gene improves salt tolerance of transgenic maize mediated with minimum linear length of DNA fragment.
1989) that results in an inability to convert choline to betaine aldehyde
, the first committed step in the synthesis of GB (Lerma et al.
An important metabolic pathway for choline involves its conversion into glycine via betaine aldehyde
, betaine, N,N-dimethylglycine (DMG)  and sarcosine (Fig.
ORF1 (TMABaldehyde-DH), which encodes 496 amino acids also shares identity with betaine aldehyde
dehydrgenase of Pseudomonas aeruginosa, TMABaldehyde-DH of rat liver (Fig.
1993) because of a deficiency in choline monooxygenase and betaine aldehyde
dehydrogenase (Rathinasabapathi et al.
