| Zusammenfassung: | Copyright © 2018 Elsevier Masson SAS. All rights reserved. Arabidopsis AP2 FAMILY PROTEIN INVOLVED IN DISEASE DEFENSE (APD1) is a member of AP2/EREBP super-family that positively regulates SA biosynthesis and defense against virulent bacterial pathogens. Here we report additional roles of APD1 in plant defense and development. We show that APD1 function is required for light-mediated defense against bacterial pathogens and systemic acquired resistance (SAR). We demonstrate that APD1 function is not required for generating SAR mobile signal at the site of primary inoculation but is required at the distal end for SAR manifestation. In addition, the APD1 function is required for PTI-induced callose deposition, defense against necrotrophic pathogen Botrytis cinerea and Alternaria alternata, which are ethylene (ET) or ethylene-Jasmonate (JA) dependent responses. Development of seedling under dark and ET is partly dependent on APD1. The mutant apd1 plants are non-responsive towards exogenous ACC application regarding apical hook formation and hypocotyl shortening, however, possess WT-like ET-mediated root growth inhibition. JA-mediated root growth inhibition is also impaired in apd1 seedlings. Altogether our results suggest that APD1 impacts multiple aspects of plant growth and development |
