Figure 10. A schematic presentation of retrograde signaling in
plant cells.
Environmental factors in this study are the chloroplast development
inhibitors LIN and NF which act in the chloroplast (shown by the yellow
arrows) and generate photooxidative damage under high light. The signal
generated by the chloroplast is transduced to the nucleus (shown by a
red line) causing the necessary changes in NGE (plastid retrograde
signaling). The transcriptome analysis shows that the expression of
chloroplast and mitochondrial retrograde signaling-related genes is
affected in AT5G08670 seedlings treated with LIN and associated
with the repression of some TFs, such as ETT, PTF1, TCP2 , andKTF1 .
