Comparative transcriptome profiling of vanilla (Vanilla planifolia) capsule development provides insights of vanillin biosynthesis.

ABSTRACT:

Background

Vanillin is the most abundant volatile compound in natural vanilla extract and the primary metabolite from an economic perspective. Natural vanilla is the second most expensive spice in the world and the most profitable crop adapted to the warm tropics. Despite its global popularity, vanilla is mainly cultivated from vegetatively propagated clones and insufficient modern plant breeding has been achieved. One of the breeding objectives is to increase the vanillin concentration in the cured vanilla capsules. The vanillin biosynthesis pathway has not been thoroughly deciphered and multiple hypotheses are considered.

Results

A comparative transcriptomic approach between two accessions with contrasting vanillin content was used to fill in knowledge gaps on vanillin bio
