title: salt stress at 6day
design: Methods: After one month, we randomly selected the seedlings that had similar lengths and exhibited good growth to subject them to the salt treatments. The treatments involved salt stress, with one group irrigated with distilled water (control) and another group irrigated with NaCl at 100 mmol L, and each treatment had three replicates. Each rootstock has 120 seedlings, and each pot has 5 seedlings of rootstock. The seedlings were irrigated every 3 days until 18 days of salt stress. At 0, 6, and 12 days of the treatments, the fourth leaf that fully unfolded was collected and stored at 80 directly for the RNA-seq analysis. Three biological replicates were made.
