Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations. Here, we will extend our pioneering efforts that have mapped and discovered novel root cell types, to determine their salt and nutrient stress responses, and to elegantly dissect the underling causal genetic variation. The unique cell markers and regulatory networks will be validated with tissue specific and transgenic tools that can work across a host of plant species to reveal adaptive cellular responses to harsh environmental conditions.

植物基因组学已经发展到单细胞分辨率，允许精确调查以前隐藏的细胞类型和细胞状态，这些细胞类型和细胞状态对环境胁迫做出反应，并且在差异适应的植物种群中变化。在这里，我们将扩展我们的开拓性努力，绘制和发现新的根细胞类型，以确定它们的盐和营养胁迫反应，并优雅地剖析潜在的因果遗传变异。独特的细胞标记和调控网络将通过组织特异性和转基因工具进行验证，这些工具可以在许多植物物种中发挥作用，以揭示对恶劣环境条件的适应性细胞反应。
