^a 14-d-old-seedling.

^b 14-d-old-seedling treated with 200 mM NaCl.

^c 14-d-old-seedling grown under cold stress at 4°C for 24 h in darkness.

^d 14-d-old-seedling treated with 20% PEG-6000.

^e The percentage of co-cis-NATs in the corresponding total cis-NATs was calculated.

^f Small RNAs were only enriched in the overlapping regions with more than five reads.

^g The density of siRNAs in overlapping regions was > 5 times that in non-overlapping regions.
