Abstract :
[en] The PHOSPHATIDYLETHANOLAMINE-BINDING PROTEIN (PEBP) gene family is present in all
eukaryotic kingdoms. In plants, three separate subfamilies have been identified, all of
which have diversified functions. In Arabidopsis thaliana, the PEBP family members have
been assigned roles as promoting or repressing flowering, controlling inflorescence
meristem determinacy and axillary bud growth. Members of the PEBP family have also
been identified to play a role in tuber initiation in potato but not much is known about the
role of PEBPs in root development, especially for species that form storage roots.
Root chicory (Cichorium intybus var. sativum) is a biennial crop used for nutrition, animal
feed and as coffee substitute and is one of the most important sources of inulin, a type of
polysaccharides that is gaining great importance in the food and medical industry.
Chicory root extracts have been found to have hepatoprotective, anti-bacterial, anti-
inflammatory, anti-microbial, nematicidal and anti-cancer effects.
With the use of bioinformatic tools, the sequences of chicory FLOWERING LOCUS T (CiFT)
and TERMINAL FLOWER1 (CiTFL1-1 to 4) like genes were identified and the coding
sequences were overexpressed in null A. thaliana mutants (ft-10 or tfl1). Independent
transgenic lines for each gene were phenotyped for flowering time and root development.
In addition, the expression pattern of these genes was analyzed in chicory in various
tissues during early stages of plant development and initiation of root storage.
Transformation of chicory is being performed using an Agrobacterium rhizogenes in vitro
transformation protocol. The results of this project will help us elucidate the role for the
PEBPs in flowering and root development in chicory.
