11th International Conference on Agricultural Research, 16-19 July 2018, Athens, Greece
|1||A Stream on “New Horizon in Plant Abiotic Stress Physiology and Molecular Biology”|
Dr. FeiBo Wu, Professor & Deputy Director, Institute of Crop Science, College of Agriculture & Biotechnology, Zhejiang University, China.
The aim of this stream is to bring together academic researchers as well as practitioners of the field, in order to share their findings, ideas, and recommendations in a professional setting. The stream will cover the following aspects: Temperature Stress and Responses of Plants, Water Stress and Responses of Plants, Plant Signaling under Abiotic Stress Environment, New Approaches to Study Heavy Metal-Induced Stress in Plants, Functional Genomics of Stress Tolerance, Plant Epigenetics in Abiotic Stress, and Molecular Design in Crop Tolerance.

|2||A Stream on “Biochemical and Molecular Mechanisms of Plant Response to Attack of Arthropods Pests”|
Dr. Cezary Sempruch, Associate Professor, Siedlce University of Natural Sciences and Humanities, Poland.
The selection and acceptance of the host plants by the pests is conditioned by a succession of the following stimuli. The colour of plants resulted from content of dyes, affects considerable distances. At a shorter distance, the fragrance stimuli are conditioned by the presence of specific volatile compounds. Such biomolecules may also induce indirect defence mechanisms, attracting natural enemies. In the next stage, herbivores must break down barriers that occur on the surface of plant organs, among others with the presence of epicuticular waxes. After overcoming these barriers, arthropods assess the nutrient resources and/or the presence of antifeedants and toxins. As a result, the course of interaction between herbivores and/or their host plants is the result of the interaction of many plant biomolecules with diverse structures and properties.
In addition, plants have induced resistance mechanisms. It involves responding to threats from herbivorous arthropods, by activating appropriate biochemical and molecular defence mechanisms, including local hypersensitive response (HR) and systemic defence mainly dependent on the salicylate signalling pathway (SAR) or the jasmonate and ethylene signalling pathways (ISR).
The above-outlined issue is currently of interest to many researchers, and the data they acquire in addition to cognitive values is also of application importance. They provide information for rational selection and immunization of plants, which plays a significant role in modern programs of integrated crop protection.
