Fig. 5From: Exogenous melatonin enhances salt secretion from salt glands by upregulating the expression of ion transporter and vesicle transport genes in Limonium bicolorEffects of NaCl and melatonin on salt secretion of salt glands of L. bicolor leaves. a-d, the ability of salt secretion of leaves with leaf disc method, a, 0 + 0, 0 mM NaCl+ 0 μM MT; b, 0 + 5, 0 mM NaCl+ 5 μM MT; c, 300 + 0, 300 mM NaCl+ 0 μM MT; d, 300 + 5, 300 mM NaCl+ 5 μM MT; e, The total amount of Na+ secreted by a single leaf; f, the total amount of Na+ secreted by a salt gland. The values are the average of five biological repeats ± standard deviation. According to Duncan’s multi-range tests, bars that there were significant differences at P < 0.05 are labeled with different lettersBack to article page
