Dynamic chromatin accessibility and transcription in salt-tolerant heterosis of Brassica napus

Three Brassica napus materials (2063A, B409 and HZ62)growth in Hoagland nutrient solution with 220 mM/L NaCl condition for 0 h, 1 h, 3 h, 6 h, 12 h, 24 h and 48 h post salt stress Overall design: Samples were collected from the three materials (2063A, B409 and HZ62) during salt stress treatments at a concentration of 1.25% NaCl at the following time points: 0 h, 1 h, 3 h, 6 h, 12 h, 24 h and 48 h post salt stress, and all samples underwent ATAC-seq and mRNA-seq.
