The ZmNAC1 gene and its expression patterns . A. Structure of the ZmNAC1 gene. The first intron is 1835 nucleotides in length, with the 5^′splice junction at cDNA position 523 bp; the second intron is 960 nucleotides in length, with the 5’splice junction at position 794 bp. The boxes and lines depict the exon and intron sequences, respectively. The arrowhead represents the translation start and stop site. B. The root phenotype of 6-day-old seedlings from 87-1 and Zong3. C. Expression analysis of ZmNAC1 for inbred line 87-1 and Zong3 by real-time PCR.
