Despite that the modern crops are mainly intensive, high yield with good resistance to biotic and abiotic stresses, in some regions up to 30% yield are lost every year because of diseases or other stresses. Biotic Stress occurs as a result of damage done to plants by other living organisms, such as bacteria, viruses, fungi, parasites, beneficial and harmful insects, weeds, and cultivated or native plants. Therefore, understanding the mechanisms of resistance to plant biotic stress and plant diseases is one of the hottest areas of modern plant science. The main goal of the International Conference “Plant Biotic Stresses & Resistance Mechanisms II” is to bring researchers from academy and industry to present and evaluate the most recent advances in understanding and combating plant biotic stress and resistance mechanisms and to define new frontiers in this field. The program of Plant Biotic Stresses & Resistance Mechanisms II Conference combines plenary lectures and session talks, posters sessions, special sessions on career development, and tours of the beautiful city of Vienna. Approximately 250-300 participants are expected, including more than 35 speakers and many presentations, selected from abstracts.
