SRP326637 PRJNA743229 GSE179319 Transcriptomic analysis of Serratia marcescens PLR treated Arabidopsis. The main purpose of this work is to clarify the effect of bacterial PLR on lateral root development in Arabidopsis, especially focusing on the fluctuation of auxin signaling in plants, so as to explain that PLR promotes lateral root development by promoting auxin signaling in plants. Overall design: We isolated total RNA from the 7-day-old Col-0 seedlings with or without Serratia marcescens PLR treatment. GSE179319
