Abstract:Non-photochemical quenching (NPQ) is an essential process protecting plants from oxidative damage under high light conditions. During the transition from light to shade, photosynthesis is briefly limited based on the rate of NPQ relaxation. Increasing expression of NPQ mediating proteins (VDE, ZEP, & PSBS) using an Arabidopsis T-DNA cassette in Nicotiana tabacum L. (tobacco) has been shown to improve the rate of NPQ relaxation, resulting in yield increases under both greenhouse and field conditions (Kromdijk et al., 2016). However, the pleiotropic effects of this gene manipulation have yet to be examined. To address this a comparative, multi-omics approach, two previously described transgenic tobacco lines (VPZ23 & VPZ34) with increased rates of NPQ relaxation were analyzed. The results indicate minimal, but directed, changes to the transformants’ transcriptome and proteome centered that could lower plant biotic defenses.
