Abstract:
Nitrogen (N) is an essential macronutrient and its bioavailability plays a major role in tuning plant development to the environmental nutrient status. To find novel factors in early root system architecture responses to N conditions, we performed Arabidopsis thaliana root transcriptome profiling of a short-term time course in limiting and sufficient N conditions. Using this data, we inferred transcriptional regulatory networks in each condition, which revealed the N-condition specific jasmonate responses. We found that the transcription factor (TF) ERF107 plays a generalized role in lateral root development while LBD13 is specific to N-limiting conditions. Further, we used a lateral root single-cell-identity specific transcriptome dataset to model the roles of TFs in early stages of lateral root development. We linked the N time course transcriptomics, lateral root mutant phenotypes and cell type-specific profiling approaches to find and test the roles of TFs that are involved in early root patterning responses to N conditions.
