Abstract
The form and function of plants are largely governed by communication among cells, tissues and organs, and cross-talks with environmental stimuli. In higher plants, phytohormones are a fountain of efficient communication to coordinate plant growth and morphogenesis by efficiently distributing carbon energy along the life cycle. During a last decade, our laboratory has been elucidating signaling networks of key phytohormones such as cytokinin, auxin, brassinosteroid, abscisic acid, and salicylic acid for plant developmental processes under various environmental conditions. To this end, we have constructed our own ‘interactome’ database and molecular networks as a platform to explore the cross-talks among different phytohormones and environmental conditions, and investigated epigenetic regulations of the induced resistance (e.g. priming) against bacterial pathogen at genome level. Recently, we are keen on understanding how secondary organs such as lateral roots, cambia, and nodules in legume plants are initiated and developed in accordance to environmental changes. The understanding of these complicated developmental processes, we believe, would be essential and critical to understanding life at least in plants.
