报告内容：
Plant roots play a crucial role in sustaining life on Earth, anchoring plants in soil and facilitating the absorption of vital water and nutrients essential for their growth and, consequently, our food production. Roots comprise an intricate array of cells with varying shapes and sizes, yet many of their intricacies remain undiscovered. To fully grasp the hidden world beneath the soil, we must gain comprehensive insights into the cellular composition of roots. Questions surrounding the transmission of signals between root cells and their communication with above-ground plant components beg answers. Enhanced knowledge of root cell biology and genetics empowers us to decipher why some roots exhibit superior resilience against environmental stresses such as heat, drought, or flooding. Regrettably, a readily accessible root cell atlas, a critical tool for this purpose, remains elusive. Our initiative, the RootCellAtlas, offers scientists an invaluable resource for comprehending the intricacies of root life. Employing cutting-edge research techniques, we can now pinpoint the expression of all 27,000 genes in individual root cells. This yields unique gene expression profiles, which are then superimposed onto a virtual root. Consequently, researchers worldwide can easily decipher how specific genes manifest in root cells and distinguish them across various cell types and subtypes. This approach provides invaluable insights into the genetic underpinnings of root cell formation, paving the way for a deeper understanding of root development and beyond at the molecular level.
