Arabidopsis Trait Ontology

This dataset offers a detailed collection of traits centered on nitrogen use efficiency (NUE) in Arabidopsis thaliana, with a focus on nitrogen uptake and nitrogen remobilization processes. It includes variables describing dry weight measurements of various plant organs, such as roots, rosettes, stems, siliques, and seeds, across different growth stages. Each trait is accompanied by metadata covering the context of use, method of measurement, scale, and relevant references. The data are organized to facilitate the development of an Arabidopsis Trait Ontology, supporting comparative analysis and integration across studies. The dataset is intended to be shared with the community to advance research on Arabidopsis and related species.本数据集围绕拟南芥（Arabidopsis thaliana）的氮利用效率（nitrogen use efficiency, NUE）搭建了一套详尽的性状集合，重点聚焦于氮吸收与氮再转运过程。数据集涵盖描述不同生长阶段下，拟南芥各器官（根、莲座、茎、角果与种子）干重测定值的变量。每个性状均附带元数据，涵盖应用场景、测定方法、量纲尺度及相关参考文献。本数据集的组织形式旨在助力拟南芥性状本体（Arabidopsis Trait Ontology）的构建，为跨研究的比较分析与数据整合提供支撑。本数据集面向科研社区开放共享，以推动拟南芥及相关物种的研究进展。
