Proteomic Analysis Provides Insights into Arabidopsis thaliana Response Under Narrow-Wavelength LED of 595 nm light
Author(s): Nafiseh Yavari* and Mark G. Lefsrud
A growing body of evidence has highlighted that a wide range of plant processes including growth, photosynthesis, and stress response are regulated by 595 nm light. However, the molecular mechanisms underlying 595 nm-induced signals are not known. The aim of this work was to study the comparative proteomic changes in leaves of Arabidopsis thaliana Col-0 plants treated with narrow-wavelength 595 nm light or fluorescent light for 5 days. Harvested plant samples were analyzed using inline RP-SCX-RP liquid chromatography coupled with LTQ mass spectrometer, resulting in the identification of 1538 proteins. Linear regression modeling of proteins’ relative abundance revealed a total of 23 differentially abundant proteins (DAPs). Functional analysis of these DAPs demonstrated the role of several biological mechanisms in A. thaliana’s response to 595 nm light incl.. View More»
