摘要:

为探究CaCl2浸种对西蓝花芽苗菜生长和活性物质含量的影响,并从分子水平阐明CaCl2对硫苷的调控机制,以西蓝花种子为试材,采用0(CK)、1.0、2.5、5.0和10.0 mmol·L-1CaCl2溶液进行浸种处理,比较不同处理下芽苗菜生长指标、营养物质含量和硫苷含量的变化,并利用实时荧光定量PCR技术检测脂肪族硫苷合成关键基因的表达水平。结果表明,不同浓度CaCl2处理均能促进西蓝花芽苗菜的伸长生长,但对生物量、维生素C含量和叶绿素含量无显著影响;低浓度CaCl2处理可提高可溶性糖、可溶性蛋白、类胡萝卜素和脂肪族硫苷含量;各浓度CaCl2处理均能上调西蓝花芽苗菜中MYB28ElongCYP79F1CYP83A1UGT74B1ST5b基因的转录水平。基于主成分分析的综合评价得分显示,5个处理的综合效果排序为:2.5 mmol·L-1CaCl2>1.0 mmol·L-1CaCl2>CK>10.0 mmol·L-1CaCl2>5.0 mmol·L-1CaCl2。综上,CaCl2浸种能够促进西蓝花芽苗菜中脂肪族硫苷合成相关基因的表达,其中2.5 mmol·L-1CaCl2处理在促进生长和生物活性物质积累方面效果最佳。

Abstract:

To investigate the effects of CaCl2 seed soaking on the growth and bioactive compound content of broccoli sprouts and to elucidate the regulatory mechanism of CaCl2 on glucosinolates at the molecular level, broccoli seeds were used as the test material. Seed soaking treatments were performed using 0 (CK), 1.0, 2.5, 5.0 and 10.0 mmol·L-1CaCl2 solutions. Changes in growth indices, nutrient content, and glucosinolate content of the sprouts under different treatments were compared, and the expression levels of key genes involved in aliphatic glucosinolate biosynthesis were detected using real-time quantitative PCR. The results showed that CaCl2 treatments at different concentrations all promoted the elongation growth of broccoli sprouts, but had no significant effect on biomass, vitamin C content, and chlorophyll content. Low-concentration CaCl2 treatments increased the contents of soluble sugars, soluble proteins, carotenoids and aliphatic glucosinolates. All CaCl2 treatments upregulated the transcription levels of MYB28, Elong, CYP79F1, CYP83A1, UGT74B1 and ST5b genes in broccoli sprouts. The comprehensive evaluation scores based on principal component analysis showed the ranking of overall effects for the five treatments as follows: 2.5 mmol·L-1CaCl2>1.0 mmol·L-1CaCl2>CK>10.0 mmol·L-1CaCl2>5.0 mmol·L-1CaCl2. In conclusion, CaCl2 seed soaking can promote the expression of genes related to aliphatic glucosinolate biosynthesis in broccoli sprouts, with the 2.5 mmol·L-1CaCl2 treatment showing the best effect in promoting growth and the accumulation of bioactive compounds.
