Abstract

BACKGROUND

Lunasin is a novel therapeutic peptide that was initially isolated from soybean. In this study, we quantified the variations in lunasin content in a total of 413 soybean samples that were collected from four major regions in China and harvested in 2014 and 2015 to reveal the regional distribution of soybean lunasin content in China and the effects of climate factors.

RESULTS

The results showed that the cultivar Changmidou 30 collected from Jilin province and harvested in 2015 had the highest lunasin content (3.25 g kg dry seeds). The data from both 2014 and 2015 showed that the lunasin content in soybean collected from northern China was significantly higher (P < 0.05) than that from south China. There was a positive correlation (P < 0.01) between lunasin content and hours of sunshine (HS) as well as diurnal temperature range (DTR); however, there was a negative correlation (P < 0.01) between lunasin content and rainfall (RF). In addition, combined analysis of data from 2014 and 2015 demonstrated that DTR was the dominant factor that affected lunasin content with a direct path-coefficient of 0.301.

CONCLUSIONS

摘要

背景

Lunasin 是一种新型的治疗性肽，最初从大豆中分离出来。在这项研究中，我们对 2014 年和 2015 年从中国四个主要地区采集的 413 个大豆样本进行 lunasin 含量的变化进行了定量分析，以揭示中国大豆 lunasin 含量的区域分布以及气候因素的影响。

结果

结果表明，2015 年从吉林省采集的 Changmidou 30 品种的 lunasin 含量最高（3.25g/kg 干种子）。2014 年和 2015 年的数据均表明，来自中国北方的大豆 lunasin 含量明显高于南方（P<0.05）。lunasin 含量与日照时数（HS）和昼夜温差（DTR）呈正相关（P<0.01）；然而，与降雨量（RF）呈负相关（P<0.01）。此外，对 2014 年和 2015 年的数据进行联合分析表明，DTR 是影响 lunasin 含量的主要因素，其直接路径系数为 0.301。
