The analysis of the molecular response of entire plants or organs to environmental stresses suffers from the cellular complexity of the samples used. Specifically, this cellular complexity masks cell-specific responses to environmental stresses and logically leads to the dilution of the molecular changes occurring in each cell type composing the tissue/organ/plant in response to the stress. Therefore, to generate a more accurate picture of these responses, scientists are focusing on plant single cell type approaches. Several cell types are now considered as models such as the pollen, the trichomes, the cotton fiber, various root cell types including the root hair cell, and the guard cell of stomata. Among them, several have been used to characterize plant response to abiotic and biotic stresses. In this review, we are describing the various -omic studies performed on these different plant single cell type models to better understand plant cell response to biotic and abiotic stresses.
对整个植物或器官对环境胁迫的分子反应进行分析，会受到所用样本细胞复杂性的影响。具体而言，这种细胞复杂性掩盖了细胞对环境胁迫的特异性反应，并且从逻辑上导致构成组织/器官/植物的每种细胞类型中因胁迫而发生的分子变化被稀释。因此，为了更准确地了解这些反应，科学家们正专注于植物单细胞类型研究方法。现在有几种细胞类型被视为模型，如花粉、毛状体、棉纤维、包括根毛细胞在内的各种根细胞类型以及气孔保卫细胞。其中，有几种已被用于表征植物对非生物和生物胁迫的反应。在本综述中，我们描述了对这些不同植物单细胞类型模型进行的各种组学研究，以便更好地了解植物细胞对生物和非生物胁迫的反应。
