Abstract：
BACKGROUND: The expression of biological traits is modulated by genetics as well as the environment, and the level of influence exerted by the latter may vary across characteristics. Photosynthetic traits in plants are complex quantitative traits that are regulated by both endogenous genetic factors and external environmental factors such as light intensity and CO2 concentration. The specific processes impacted occur dynamically and continuously as the growth of plants changes. Although studies have been conducted to explore the genetic regulatory mechanisms of individual photosynthetic traits or to evaluate the effects of certain environmental variables on photosynthetic traits, the systematic impact of environmental variables on the dynamic process of integrated plant growth and development has not been fully elucidated.
RESULTS: In this paper, we proposed a research framework to investigate the genetic mechanism of high-dimensional complex photosynthetic traits in response to the light environment at the genome level. We established a set of high-dimensional equations incorporating environmental regulators to integrate functional mapping and dynamic screening of gene‒environment complex systems to elucidate the process and pattern of intrinsic genetic regulatory mechanisms of three types of photosynthetic phenotypes of Populus simonii that varied with light intensity. Furthermore, a network structure was established to elucidate the crosstalk among significant QTLs that regulate photosynthetic phenotypic systems. Additionally, the detection of key QTLs governing the response of multiple phenotypes to the light environment, coupled with the intrinsic differences in genotype expression, provides valuable insights into the regulatory mechanisms that drive the transition of photosynthetic activity and photoprotection in the face of varying light intensity gradients.
CONCLUSIONS: This paper offers a comprehensive approach to unraveling the genetic architecture of multidimensional variations in photosynthetic phenotypes, considering the combined impact of integrated environmental factors from multiple perspectives.

摘要：
背景：生物性状的表达受遗传和环境的调节，后者施加的影响水平可能因特征而异。植物的光合性状是复杂的数量性状，受内源遗传因素和外界环境因子如光照强度和CO2浓度的双重调控。受影响的特定过程随着植物生长的变化而动态且连续地发生。尽管已经进行了研究以探索单个光合性状的遗传调控机制或评估某些环境变量对光合性状的影响，环境变量对植物综合生长发育动态过程的系统影响尚未完全阐明。
结果：在本文中，我们提出了一个研究框架，在基因组水平上研究高维复杂光合性状响应光环境的遗传机制。我们建立了一组包含环境调节因子的高维方程，以整合基因-环境复杂系统的功能定位和动态筛选，以阐明随光强变化的三种类型的胡杨光合表型的内在遗传调控机制的过程和模式。此外，建立了网络结构来阐明调节光合表型系统的重要QTL之间的串扰。此外,控制多种表型对光环境响应的关键QTL的检测，再加上基因型表达的内在差异，提供了有关在面对变化的光强度梯度时驱动光合活性和光保护过渡的调节机制的宝贵见解。
结论：本文提供了一种全面的方法来揭示光合表型多维变异的遗传结构，从多个角度考虑综合环境因素的综合影响。
