Left, Functionally active Arabidopsis (At) or human (Hs) NAA50 is required for normal development, growth, and the repression of stress responses in Arabidopsis. NAA50 was shown to interact with the negative defense regulator ENHANCED DISEASE RESISTANCE1 [EDR1]. Right, Loss of functional NAA50 (naa50 mutants ± complementation with yeast ScNAA50) leads to strongly impaired plant growth and development. Reduced NAA50 levels also result in ER stress, constitutive stress responses, and hormone signaling (abscisic acid [ABA], jasmonic acid [JA], SA, and ethylene [ET]) at both the transcriptional (Neubauer and Innes, 2020) and proteome levels (Armbruster et al., 2020). These altered processes may directly or indirectly contribute to the impaired growth and development of naa50 mutants. Images were adapted from figure 4C of Armbruster et al. (2020).
