Identity of root peridermis cells undergoing suberization in Arabidopsis

In order to unravel the molecular processes involved in the nature of the root peridermis tissue, as well as in the suberin biosynthesis pathways occurring in this tissue, we have made use of Translating Ribosome Affinity Purification (TRAP) followed by RNA sequencing (TRAP-SEQ) on two marker lines; pUBQ10::BLRP-FLAG-GFP-RPL18 and pGPAT5::BLRP-FLAG-GFP-RPL18 line, after dissection of a zone of the root comprised between the root-hypocotyl junction and the first lateral root, allowing the respective selection of RNAs originating from all cells of the root segment, or only from those peridermis cells expressing the GPAT5 marker and therefore undergoing suberization.
