日本的几个地区特有的蔬菜品种有着广泛的种植历史。独特的味道和香味使其适合用于香料和泡菜，多年来，具有高含量功能性含硫化合物的品种已被优先选择。在本研究中，我们调查了不同根际硫酸盐浓度（0，0.2，0.4和0.8 mM）的干重和硫含量的40个品种的兰科传家宝蔬菜的影响。我们还分析了硫酸盐转运蛋白基因SULTR 1 s（SULTR 1;1、SULTR 1;2和SULTR 1;3之和）和SULTR 2;1在20个蔬菜品种中的表达水平。在0 mM硫酸盐时，植物具有小叶，以及细而稀少的根，而每株植物的平均地上部硫含量为对照的10%。硫含量增加了29%，在0.4 mM和66%，在0.8 mM硫酸盐相比，在控制（0.2 mM硫酸盐），但是，干重没有显着影响。平均芽硫浓度为0.12%在0 mM，0.52%在0.2 mM，0.65%在4 mM，0.86%在0.8 mM的硫酸盐。在几个品种中，0.4 mM硫酸盐时，地上部硫浓度超过1%。地上部含硫量与干重呈正相关，表明其对硫酸根离子的吸收能力对菊科植物的生物量有很强的影响。硫含量与SULTR 1和SULTR 2; 1的表达相关性较差，与根际硫浓度无关。这些基因不响应地上部硫含量，但响应硫酸根际水平。总之，我们的数据表明，硫酸盐吸收响应硫酸盐浓度在根际硫酸盐转运蛋白在菊科植物取决于品种的固有特性。
Several region-specific vegetable varieties in Japan have an extensive cultivation history. Distinct tastes and aromas make them suitable for use in spices and pickles, and varieties with a high content of functional sulfur-containing compounds have been preferentially selected over the years. In the present study, we investigated the effects of different rhizosphere sulfate concentrations (0, 0.2, 0.4, and 0.8 mM) on the dry weight and sulfur content of 40 varieties of Brassicaceae heirloom vegetables. We also analyzed the expression levels of sulfate transporter genes, such asSULTR1s(sum ofSULTR1;1, SULTR1;2, andSULTR1;3) andSULTR2;1, in 20 vegetable varieties. At 0 mM sulfate, plants have small leaves, as well as thin and scarce roots, whereas the mean shoot sulfur content per plant was 10% of that in control. Sulfur content increased by 29% at 0.4 mM and by 66% at 0.8 mM sulfate compared with that in control (0.2 mM sulfate); however, dry weight was not significantly affected. Mean shoot sulfur concentration was 0.12% at 0 mM, 0.52% at 0.2 mM, 0.65% at 4 mM, and 0.86% at 0.8 mM of sulfate. Shoot sulfur concentration exceeded 1% at 0.4 mM sulfate in several varieties. Shoot sulfur content and dry weight were positively correlated, suggesting that the capacity for sulfate ion absorption had a strong effect on biomass production in plants of the Brassicaceae family. Sulfur content andSULTR1sandSULTR2;1expression were poorly correlated regardless of rhizosphere sulfur concentration. These genes did not respond to shoot sulfur content but responded to sulfate levels in the rhizosphere. Overall, our data indicated that sulfate absorption response to sulfate concentration in the rhizosphere by sulfate transporters in Brassicaceae plants depends on the inherent characteristics of the variety.
