Table I. Abundance of the miR169 family in wheat.

Xiaoyan 54 seedlings were grown for 7 d in nutrient solutions that contained 2 mm N + 0.2 mm P (control), 0 mm N + 0.2 mm P (low N), and 2 mm N + 0 mm P (low P). Total RNA was isolated from roots and shoots separately for small RNA sequencing. Transcript abundance is presented as transcripts per million.
