Toward a Molecular Understanding of Plant Hormone Actions [PDF]

, 2016
Plants rely on a diverse set of small-molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone, auxin, hormones have always been at the frontier

Spatial mechanisms promoting plant coexistence. the role of dispersal and competition [PDF]

, 2009
One of the great challenges in ecology is to explain how large numbers of plant species are able to coexist in natural communities. The role of spatial structure for maintaining plant coexistence has so far mainly been explored by theory.
