Plastid signaling triggers HDA6-mediated epigenetic programs during environmental sensing in plants [RNA-seq]

Project description:Plants adapt to environmental changes by adjusting growth and defense, and the role of epigenetic modifications in this process is unclear. Sensing and adjusting to environmental changes are more important in certain tissues such as epidermis, vasculature, meristem, and reproductive tissues. These tissues possess sensory plastids that are specialized in environmental sensing. We show perturbation of four sensory plastid proteins MSH1, PPD3, CUE1, and SAL1 induce gene expression and DNA methylation changes targeted to networks associated to environmental sensing, with significant overlap with hda6-induced CHG hypermethylated genes at 12-hr daylength. At 16-hr daylength, hda6 loses CHG hypermethylation in gene body, and sensory plastid mutants have weaker phenotypes and DNA methylation- and gene expression- associated gene networks. We show daylength-responsive epistatic interaction between sensory plastid mutants with hda6. We also show that hda6 mutation confers daylength memory and, with msh1, enhanced tolerance to heat stress and biotic stress. These results suggest that HDA6 mediates programmed adjustments in plant phenotype triggered by sensory plastid-to-nucleus retrograde signaling in response to daylength and environmental cues.

Light- and plastid-regulated transcriptomes in Arabidopsis seedlings

Project description:Plastids emit signals that broadly affect cellular processes. Based on previous genetic analyses, we propose that plastid signaling regulates the downstream components of a light signaling network and that these interactions coordinate chloroplast biogenesis with both the light environment and development by regulating gene expression. We tested these ideas by analyzing light-regulated and plastid-regulated transcriptomes. We found that the plastid is a major regulator of light signaling, attenuating the expression of more than half of all light-regulated genes in our dataset and changing the nature of light regulation for a smaller fraction of these light-regulated genes. Our analyses provide evidence that light and plastid signaling are interactive processes and are consistent with these interactions serving as major drivers of chloroplast biogenesis and function.
