Described herein are methods of enhancing formation and/or growth of an adventitious root in a plant and/or plant tissue, and/or for promoting grafting unification, enhancing fruit size and/or reducing flowering in a plant. The method comprises contacting at least a portion of the plant and/or plant tissue with a compound having Formula I:

##STR00001##

wherein X, Y and R.sub.1-R.sub.7 are as defined herein. Further described are compositions for enhancing formation and/or growth of an adventitious root in a plant and/or plant tissue, and/or for promoting grafting unification, enhancing fruit size and/or reducing flowering in a plant, comprising the abovementioned compound and a horticulturally acceptable carrier. Novel compounds having Formula I are also described herein.

Methods for modulating quorum sensing in certain Gram-negative bacteria having multiple QS systems including Las, Rhl, and Pqs with associated receptors (LasR, RhlR and PqsR) which are modulated by small molecule modulators, particularly non-native modulators. Certain combinations of modulators of Las, Rhl and Pqs exhibit improved inhibition of virulence in comparison to the respective individual modulators. In particular, certain combinations of modulators exhibit improved inhibition in nutritionally depleted environments. More specifically, certain combinations of modulators exhibit improved inhibition in environments depleted in phosphate and/or environments depleted in iron. Nutrient depleted environments can mimic environments associated with bacterial infection in humans and non-human animals. The methods are useful in particular for modulating QS in Pseudomonas and Buckholderia.
