全球环境温度的升高对野生和栽培植物物种构成了重大挑战。个体温度响应性状的正向遗传分析已经导致了几个信号和响应组件的识别。然而，关于不同发育阶段的温度敏感性和自然变异的贡献的全面知识仍然是稀缺的，充其量是零散的。在这里，我们系统地分析了在16至28 °C的四种不同温度下长日照条件下生长的10种天然拟南芥种质在整个生命周期中的热形态建成。我们使用Q10，GXE，表型差异和相关分析，以评估温度敏感性和基因型的影响，超过30个形态和发育性状代表5个表型类。我们发现基因型和温度对植物生长发育的影响是不同的，且影响的强度不同。此外，表型温度反应之间的总体相关性相对较低，这似乎是由个别加入的温度适应能力差异造成的。基因型特异性的温度反应可能是有吸引力的目标，为未来的遗传方法和加入特定的热形态建成地图可能有助于评估功能相关的已知和新的监管组件。本文的在线版本（doi：10.1186/s12870-017-1068-5）包含补充材料，可供授权用户使用。
Global increase in ambient temperatures constitute a significant challenge to wild and cultivated plant species. Forward genetic analyses of individual temperature-responsive traits have resulted in the identification of several signaling and response components. However, a comprehensive knowledge about temperature sensitivity of different developmental stages and the contribution of natural variation is still scarce and fragmented at best. Here, we systematically analyze thermomorphogenesis throughout a complete life cycle in ten natural Arabidopsis thaliana accessions grown under long day conditions in four different temperatures ranging from 16 to 28 °C. We used Q10, GxE, phenotypic divergence and correlation analyses to assess temperature sensitivity and genotype effects of more than 30 morphometric and developmental traits representing five phenotype classes. We found that genotype and temperature differentially affected plant growth and development with variing strengths. Furthermore, overall correlations among phenotypic temperature responses was relatively low which seems to be caused by differential capacities for temperature adaptations of individual accessions. Genotype-specific temperature responses may be attractive targets for future forward genetic approaches and accession-specific thermomorphogenesis maps may aid the assessment of functional relevance of known and novel regulatory components.
