Transcriptome analysis of bolting in A. tequilana reveals roles for florigen, MADS, fructans and gibberellins.

ABSTRACT:

Background

Reliable indicators for the onset of flowering are not available for most perennial monocarpic species, representing a drawback for crops such as bamboo, agave and banana. The ability to predict and control the transition to the reproductive stage in A. tequilana would represent an advantage for field management of agaves for tequila production and for the development of a laboratory model for agave species.

Results

Consistent morphological features could not be determined for the vegetative to reproductive transition in A. tequilana. However, changes in carbohydrate metabolism where sucrose decreased and fructans of higher degree of polymerization increased in leaves before and after the vegetative to reproductive transition were observed. At the molecular level,
