Spatiotemporal omics have provided great new opportunities to systematically understand biological processes. The third International Plant Spatiotemporal Omics Research Conference will be held in Perth, Australia, from September 13-16, 2026. This conference aims to unite researchers worldwide to share their scientific efforts in spatiotemporal omics in plant research and to discuss the further development of STOC Plant. *STOC Plant 2026 is organized by Murdoch University, the State Key Laboratory of Genome and Multi-omics Technologies, and the Plant Spatiotemporal Omics Consortium (STOC Plant); co-organized by BGI Research, Molecular Plant and Plant Communications ; and in collaboration with BGI, MGI, Adelaide University and GigaScience.
