This meeting is designed to promote the development of a multi-disciplinary research community at an international arena, which is expected to represent diverse disciplines like proteomics, molecular and cell biology, molecular genetics, biophysical chemistry, computational biology, systems biology, medicine and agriculture. The objective of the conference is to establish comprehensive networks of hundreds of protein posttranslational modifications (PTMs) as well as the intricate modifying/demodifying enzyme-substrate cascades during the growth and development of eukaryotic model organisms. These networks of PTMs should play important roles in regulation of cell growth, signaling, differentiation, apoptosis and epigenetics under diverse physiological conditions and in response to versatile biotic and abiotic stresses. The outcomes of the PTM proteomics and molecular systems biology research will promote advancement in field of life science and ultimately be applied to agricultural and medical biotechnology to improve both crop and bioenergy productivities and to find novel remedies to diseases.
