H3K4me3 and H3K27me3 chromatin states in the Arabidopsis shoot phloem companion cells from INTACT reporter lines


ABSTRACT: We investigated the chromatin modifications H3K4me3 and H3K27me3 in the A. thaliana shoot phloem companion cells using INTACT reporter lines. Samples were collected in two biological replications.

Plants can produce organs throughout their entire life from pluripotent stem cells located at their growing tip, the shoot apical meristem (SAM). At the time of flowering, the SAM of Arabidopsis thaliana switches fate and starts producing flowers instead of leaves. Correct timing of flowering in part determines reproductive success, and is therefore under environmental and endogenous control. How epigenetic regulation contributes to the floral transition has eluded analysis so far, mostly becaus  ...[more]
