Overexpressing lncRNA973 lines are more tolerant to salt stress. a-b. Seeds were germinated on ½ MS medium containing 0 and 100 mM NaCl. Germination rates were measured during one week. c-e. Cotyledon greening, fresh weights and elongation of primary root of 7-d-old seedlings with 0–150 mM NaCl. f. Phenotype of primary root growth of 7-d-old seedlings exposed to 0–150 mM NaCl. g-i. Total chlorophyll, MDA, and Pro contents in the leaves under salt stress. j. Activities of catalase (CAT) after treatment with salt and mock. Mock, with water treatment. NaCl: 200 mM NaCl treatment. Vertical bars represent ±SD of the mean with three replicates. Asterisks indicate that mean values are significantly different between the transgenic plants and WT (p < 0.05)
