Translational regulation contributes to the elevated CO2 response in two Solanum species

Plant J. 2020 Apr;102(2):383-397. doi: 10.1111/tpj.14632. Epub 2020 Jan 16.


Understanding the impact of elevated CO2 (eCO2 ) in global agriculture is important given climate change projections. Breeding climate-resilient crops depends on genetic variation within naturally varying populations. The effect of genetic variation in response to eCO2 is poorly understood, especially in crop species. We describe the different ways in which Solanum lycopersicum and its wild relative S. pennellii respond to eCO2 , from cell anatomy, to the transcriptome, and metabolome. We further validate the importance of translational regulation as a potential mechanism for plants to adaptively respond to rising levels of atmospheric CO2 .

Keywords: Solanum; elevated carbon dioxide; genetic variation; metabolome; regulation; root; transcriptome; translatome.
