Genetic and physical interactions of Arabidopsis TOPLESS related 2 with regulators of plant innate immunity

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants are constantly subjected to attack from pathogens. In order to defend themselves, plants have evolved a robust immune system. However, activation of this immune system interferes with plant growth and development. As such, it is very important for plant health to keep the immune system properly repressed when not needed. Using genetics and microscopy we have identified a novel repressor of the plant immune system, TOPLESS RELATED 2 (TPR2). TPR2 appears to repress the immune response after activation, thereby preventing a prolonged immune response. These results help us understand how the plant immune system is regulated at a molecular level.
