Growth and Development of higher plants

Integrated interactions between at least six different classes of hormones and between these hormones and external signals strongly determine plant architecture. Within the previous IAP network, P1D was focusing on the ethylene/GA cross-talk. Recent data unveil the existence of complex signalling networks covering all hormone pathways. Hence, a major objective of WP3 is to add on the identification and understanding of the molecular links in the puzzle of hormone interactions. Hormonal cross-talk will be studied at the transcriptomic and molecular-genetic level, using tools generated both in the previous and in this IAP network.
