| Abstract: |
| This paper summarized the research presentations of the International Symposium on Crop Roots and Rhizosphere Interactions in Yangling, Shaanxi in October 2017. Scientists and scholars gathered to communicate the outcomes and developments of researches on crop roots and rhizosphere interactions. The talks at the symposium covered 6 aspects: (1) root response to stresses; (2) root system architecture and functions; (3) nutrient absorption and utilization; (4) rhizosphere and molecular mechanisms; (5) rhizosphere microorganism; and (6) modeling of rhizosphere. It was emphasized that improved crop root architecture (small root system) plays important role in improving dryland crop yields. The principle of evolution (artificial breeding) of dryland crops was expounded. It was suggested that the interactions among roots, soil, and microorganisms could be used to improve the efficiency of nutrient utilization. The development of Semi-hydroponic Phenotyping System for pot-grown plants was highlighted, and advances in understanding the molecular basis of plant responses and resistance to stress were recognized, e.g. the GmPT family gene could regulate root system architecture and nodule number. Additionally, the new methods for exploring root architecture were explored and the 3-D modeling and visualization of crop root system were carried out, so as to monitor crop nutrition conditions. It was impied from the presentations that delegates doing research in the field of root and rhizosphere interactions focused on optimizing the root architecture, accessing to high yield, high efficiency, and sustainable development of eco-agriculture. The presentations demonstrated that scientists prefer to work with multi-disciplinary intersection and applied research rather than fundamental studies. The future development direction of crop root research seems to be “applied research based on multi-disciplinary intersection”. This conference was aimed to explore new ways of sustainable ecological agricultural development, which provides an important channel for experts and scholars to cooperate and establish platforms to demonstrate the achievements in the field. In conclusion, this international symposium provided new ideas for the research of related fields. |
