Strigolactones are plant hormones with economic importance because they control shoot and root architecture, photomorphogenesis and rhizosphere interactions. The role of strigolactones will be studied on shoot regeneration of the model plant Arabidopsis thaliana (including gene discovery and functional analysis) and in economically important crops that present problems to propagate via axillary or adventitious shoots (Hevea brasilisiensis and Actinidia arguta).
