Cell type identity determines transcriptomic immune responses in Arabidopsis thaliana roots

摘要: Root pathogens are a major threat in global crop production and protection strategies required to sustainably enhance the efficiency of root immunity. Our understanding immunity is still limited relative our knowledge immune responses leaves. In an effort reveal organisation roots, we undertook cell type-specific transcriptome analysis identify gene networks epidermis, cortex pericycle cells Arabidopsis thaliana roots upon treatment with two elicitors, bacterial microbe- associated molecular pattern flagellin, endogenous damage-associated Pep1. analyses revealed that both elicitors induced type- specific networks. Interestingly, did not alter identity determining Using sophisticated paired motif promoter analyses, identified key transcription factor pairs involved regulation addition, data show integrate activate response according functional capabilities each type.
