Plant-microbe interactions toward global food security

Agriculture plays a critical role in the entire human life by providing foods, environment, energy and materials. Recent years, the world is facing crisis in terms of food security because of world's rapidly growing population. In order to feed a population of 10 billion in 50 years, the global food production must increase. Since we are also facing crises including water shortage, energy supply and climate change on a global scale, the energy-intensive conventional agriculture could accelerate environmental destruction. To achieve the sustainable agriculture, we need to develop the new agricultural system focusing not only on increasing food production, but also on reducing the loss of food production caused by weeds, pests and diseases. Actually, about 30 percent of the world's potential crop production has been lost because of the weeds, pests and diseases every year. And half of them, around 15 percent losses are due to diseases. This 15 percent food loss because of diseases is almost same amount of foods for 800 million people. Therefore, there is an increasing demand for the global food security by developing the sustainable disease control strategies. Thus, we are focusing our attentions on investigating the plant-microbe interactions toward global food security. Plant diseases are caused by living organisms such as fungi, bacteria, viruses and nematodes. Unlike human infectious diseases, more than 80% of plant disease are caused by filamentous fungi. Our primary target disease is soybean rust caused by Phakopsora pachyrhizi, which is one of the most devastating foliar diseases affecting soybean production worldwide. By working on the molecular basis of soybean-rust interactions, we are trying to establish the sustainable disease control strategies.
