Transcriptome analysis of salt-responsive and wood-associated NACs in Populus simonii × Populus nigra.

ABSTRACT:

Background

NAC (NAM, ATAF1-2, and CUC2) family is one of the largest plant-specific transcription factor families known to play significant roles in plant development processes and stress responses.

Results

In the study, a total of 112 NACs were identified to be differentially expressed in the comparisons of leaves and stems, leaves and roots, roots and stems of Populus simonii×P. nigra among 289 members by RNA-Seq. And 148, 144 and 134 NACs were detected to be salt-responsive in the roots, stems and leaves under 150 mM NaCl stress, respectively. Among them, a total of 53 salt-responsive NACs were shared across the three tissues. Under salt stress, 41/37 NACs were identified to be up/down-regulated in the leaves of Populus simonii × P.nigra among 170 non-redundant NACs by RT
