Our research delves into the intricate communication systems governing the form and function of plants, emphasizing efficient interactions among cells, tissues, organs, and responses to environmental stimuli. We focus on unraveling the signaling networks of key phytohormones such as cytokinin, auxin, brassinosteroid, abscisic acid, and salicylic acid, utilizing our proprietary 'interactome' database and molecular networks. Our investigations extend to understanding epigenetic regulations involved in induced resistance against pathogen attacks, particularly priming at the genome level. Recently, our research scope has expanded to address fundamental questions about how plants regulate cambial activities, vasculature development, and biomass production. Employing 'systems biology' approaches and interdisciplinary research, we aim to provide a comprehensive tool for deciphering these complex interactions, crucial for gaining insights into the essence of plant life.
