Frequency analysis of PAO and ATAF1 by plant line.

Both PAO (left-side) and ATAF1 (right-side) expression differed by plant line in a positively correlated manner in the GSE55907, GSE5727, and GSE72050 microarray datasets, where PAO and ATAF1 levels were either both high or both low in each plant line. A. PAO and ATAF1 levels were higher in warm conditions and certain transcription factor overexpressing lines such as HSFC overexpressing line, and were lower in the DEAR overexpressing line. B. PAO and ATAF1 levels were higher in wild-type plants during senescent conditions, in mutant jasmonic acid/ethylene pathway lines, and transgenic salicylic acid pathway line. C. PAO and ATAF1 levels were higher in drought conditions in both wild-type and NAC26-overexpressing lines and PAO levels somewhat higher and ATAF1 levels slightly lower in NAC26-overexpressing line compared to wild-type line.
