Abstract: The present invention relates to a method to isolate genes involved in the process of asymmetric cell division. The invention relates further to genes isolated using this method, and their use in controlling root formation, preferably lateral root formation.

Abstract: The present invention relates to small chemical compounds that act as activators of lateral root formation in plants. More specifically, it relates to small chemical compounds that are structurally not related to auxin but do have a similar effect on root density development in plants. Preferably, these compounds act more specifically on root development than auxin, and may have a different working mechanism.

Abstract: The present invention relates to non-steroidal mimetics of brassinosteroids. More specifically, it relates to non-steroidal monocyclic compounds, capable of rescuing the brassinosteroid receptor null mutation bri1-116. Preferably, said compounds are low molecular weight, monocyclic halogenated compound.
