    To reveal the genetic basis of the interaction between Xanthomonas pathogens and their host plants for breeding durable broad-spectrum resistance crops, the recent important progress in these fields are summarized. The devastation of plant diseases caused by Xanthomonas species is determined by Xanthomonas T3SS effectors, mainly transcription activator-like effectors (TALEs), which target effector-binding element (EBE) sites of either crop resistance (R) or susceptibility (S) genes. Then, the five types of TALE-targets in plants are briefly stated and the importance of plant general transcription factors TFIIA in the activation of NLR-type R genes in plant resistance is stressed. Finally, that gene-editing of EBEs of R or S genes is proposed to be the new strategy for resistance breeding to control crop diseases in the future.

    Development in the stem cells and tissue engineering technology provides novel ideas both for large tissue defect treatment and organ replacement. However, the vascular network in human organs is delicate and complex, which is hard to be manufactured and has become the main bottleneck in organ regeneration and transplantation. In addition, the inability to form a vascular system also restricts the size of organoids cultured in vitro from breaking through. Therefore, an idea of building synchronized functional vascular network was proposed to lay a good foundation for maintaining stem cell survival and developing organ regeneration.

    The blood-brain barrier (BBB) protects the brain against exogenous harmful compounds, but it also impedes the delivery of diagnostic and therapeutic agents to the brain, thereby hindering progress of new drug development for central nervous system (CNS) disorders. There are natural substances that can traverse the BBB emerged in organisms. A comprehensive study on their biological interactions with BBB will provide critical insights into the design and development of bioinspired brain-targeted delivery systems. In this paper, a series of brain delivery strategies were discussed with an emphasis on the bioinspired nano-delivery system which has great potential for clinical applications.

    Global climate change has led to a large amount of oxygen loss in regional and global ocean. Deoxygenation can result in biological migration and death by affecting morphology, metabolism, adaptability, etc. In addition, deoxygenation can also damage the stability of ecosystem by changing community quantity, composition, and distribution. Understanding the response of regional and global biomass and biodiversity to ocean deoxygenation can provide a theoretical basis for a sustainable management of marine ecosystem.

    Future City: How Can Urban Problems Be Solved by Nature System?
    WANG Zhaolong,LIU Lijiao
    Journal of Shanghai Jiao Tong University    2021, 55 (Sup.1): 79-81.   DOI: 10.16183/j.cnki.jsjtu.2021.S1.011

    Urbanization is an inevitable trend of global development. However, it has caused many problems such as the heat island effect, urban flooding, and environmental pollutions. Therefore, a sustainable urban development model was proposed, that is, the future city will coordinate the harmonious coexistence of humans and nature, retain stormwater, reduce urban energy consumption, and recycle urban organic wastes by adopting green infrastructures. The scientific problems that need to be solved were proposed to achieve the natural future city.

    Is Static Electricity a Friend or Foe? Triboelectric Effect for Ambient Energy Harvesting
    CHO Yuljae
    Journal of Shanghai Jiao Tong University    2021, 55 (Sup.1): 84-85.   DOI: 10.16183/j.cnki.jsjtu.2021.S1.013

    You might remember that you hesitated to grab a knob in fear of the static electricity. Although static electricity was observed by Thales in B.C.600, its mechanisms had been elusive for several thousand years. In recently years, this seemingly impregnable mystery has been partially unraveled by several researches showing that static electricity is caused by the deformation of protrusion on materials at the nanoscale. This one step forward in understanding electrostatics will bring vast opportunities in a number of applications. Now we human beings hold the key to turning electrostatics from a foe into friend.

    Sustainable Agriculture and Desert Bloom via Atmospheric Water Harvesting
    WANG Chenxi,ZOU Hao,WANG Ruzhu
    Journal of Shanghai Jiao Tong University    2021, 55 (Sup.1): 88-90.   DOI: 10.16183/j.cnki.jsjtu.2021.S1.015

    The contradiction between supply and demand of agricultural irrigation water is becoming increasingly prominent under the influence of population growth, cultivated land reduction, climate change and so on. Especially in the desert areas, the sustainable development requires effective access to water resources and the realization of water-saving and energy-saving planting. The technology of adsorption-based atmospheric water harvesting can get rid of the limitation of geographical location and capture considerable fresh water resources from the air, providing sustainable irrigation water for agriculture development. In the application scenario of greenhouses, the water harvesting device can adsorb the vapor from the moist air, regulate indoor humidity, and release adsorption heat. The water collected in the desorption process could be recycled for greenhouse irrigation. Furthermore, the technology would be potentially applied in urban farming and desert bloom.
