Abstract

Objective: In order to explore the impacts of environmental hormones (EHs) on plants, the relationship between EHs pollutants and Spinacia oleracea HSP70-9 expression was studied in this paper. The researchers studying HSP70 have primarily investigated high temperature stress, low temperature stress, water stress and other environmental factors, such as heavy metals, wind stress, salt stress. However, as a type of environmental pollutant, EHs may affect the growth and development of plants.
Methods: Two typical EHs, PAEs (phthalates esters) and BPA (bisphenol A), were selected for the study. RT-qPCR was used to study HSP70-9 expression at the transcriptional level under single and combined pollution conditions in spinach seedlings.
Results: The result of the present study showed that, the spinach HSP70-9 expression is downregulated with single and combined treatments of EHs.
Conclusion: The conclusion is that BPA and PAEs had certain effects on the expression of HSP70-9 in spinach.
