辣椒(Capsicum annuum)悬浮细胞培养物被用来评估环糊精和甲基茉莉酸作为诱导防御反应的激发剂的效果。诱导的防御反应包括倍半萜和植物甾醇的积累以及相关蛋白的激活,这些蛋白在激发和保护细胞对抗生物胁迫期间强化和修改细胞壁结构。结果表明,添加环糊精和甲基茉莉酸都能诱导两种倍半萜,香树烯和索拉维通酮的生物合成。这种反应显然是协同的,因为当两种激发剂同时使用时,这些化合物的水平增加远大于单独使用时的水平。在联合处理中,植物甾醇的生物合成也被诱导,这是由于加性效应。同样,外源应用甲基茉莉酸诱导了相关蛋白的积累。对外泌蛋白组进行分析,发现了与PR1和4、NtPRp27样蛋白和I类几丁质酶、过氧化物酶以及水解酶LEXYL1和2、阿拉伯糖苷酶、果胶酶、花蜜蛋白IV和富含亮氨酸重复蛋白同源的氨基酸序列,这表明甲基茉莉酸在介导辣椒防御相关基因产物的表达中发挥作用。除了这些由甲基茉莉酸诱导的蛋白外,还在辣椒的对照和激发细胞培养中发现了其他相关蛋白。这些包括IV类几丁质酶、beta-1,3-葡萄糖苷酶、thaumatin样蛋白和过氧化物酶,这表明它们的表达主要是组成型的,因为它们参与生长、发育和防御过程。
Capsicum annuum /(C. annuum)/ suspension cell cultures were used to evaluate the effect of cyclodextrins and methyl jasmonate as elicitors of defense responses. The induced defense responses included the accumulation of sesquiterpenes and phytosterols and the activation of pathogenesis-related proteins, leading to reinforcement and modification of the cell wall architecture during elicitation and protection cells against biotic stress. The results showed that the addition of both cyclodextrins and methyl jasmonate induced the biosynthesis of two sesquiterpenes, aromadendrene and solavetivone. This response was clearly synergistic since the increase in the levels of these compounds was much greater in the presence of both elicitors than when they were used separately. The biosynthesis of phytosterols was also induced in the combined treatment, as the result of an additive effect. Likewise, the exogenous application of methyl jasmonate induced the accumulation of pathogenesis-related proteins. The analysis of the extracellular proteome showed the presence of amino acid sequences homologous to PR1 and 4, NtPRp27-like proteins and class I chitinases, peroxidases and the hydrolytic enzymes LEXYL1 and 2, arabinosidases, pectinases, nectarin IV and leucin-rich repeat protein, which suggests that methyl jasmonate plays a role in mediating defense-related gene product expression in C. annuum. Apart from these methyl jamonate-induced proteins, other PR proteins were found in both the control and elicited cell cultures of C. annuum. These included class IV chitinases, beta-1,3-glucanases, thaumatin-like proteins and peroxidases, suggesting that their expression is mainly constitutive since they are involved in growth, development and defense processes.

硼是植物所需的一种微量元素,但如果在土壤中过量存在,对某些植物如含有青蒿素(一种重要的抗疟疾药物)的青蒿(Artemisia annua L.,又称A. annua)来说,它会对植物产生毒性。青蒿素是一种带有内过氧桥的倍半萜内酯...当前的研究旨在确定外源施用茉莉酸甲酯(MeJA)是否能对抗土壤中过量硼(B)带来的不利影响。根据获得的结果,硼毒性引起的氧化应激显著降低了植物的株高以及鲜重和干重。土壤中过量的硼也降低了叶片的净光合速率、气孔导度、内部CO2浓度和总叶绿素含量。相比之下,叶面施用MeJA增强了受胁迫和未受胁迫植物的生长和光合效率。过量的硼水平也增加了抗氧化酶如过氧化氢酶、过氧化物酶和超氧化物歧化酶的活性...将MeJA应用于受胁迫的植物减少了脂质过氧化的量,并刺激了抗氧化酶的合成,同时提高了青蒿素的含量和产量。因此,可以得出结论,MeJA可能用于缓解硼毒性,并提高青蒿植物中青蒿素含量和产量。
Boron is an essential plant micronutrient, but it is phytotoxic if present in excessive amounts in soil for certain plants such as Artemisia annua L. /(A. annua)/ that contains artemisinin (an important antimalarial drug) in its areal parts. Artemisinin is a sesquiterpene lactone with an endoperoxide bridge... the present research was conducted to determine whether the exogenous application of methyl jasmonate (MeJA) could combat the ill effects of excessive /Boron stress/ (B) present in the soil. According to the results obtained, the B toxicity induced oxidative stress and reduced the stem height as well as fresh and dry masses of the plant remarkably. The excessive amounts of soil B also lowered the net photosynthetic rate, stomatal conductance, internal CO2 concentration and total chlorophyll content in the leaves. In contrast, the foliar application of MeJA enhanced the growth and photosynthetic efficiency both in the stressed and non-stressed plants. The excessive B levels also increased the activities of antioxidant enzymes, such as catalase, peroxidase and superoxide dismutase... the MeJA application to the stressed plants reduced the amount of lipid peroxidation and stimulated the synthesis of antioxidant enzymes, enhancing the content and yield of artemisinin as well. Thus, it was concluded that MeJA might be utilized in mitigating the B toxicity and improving the content and yield of artemisinin in A. annua plant.

制备方法与用途

简介

茉莉酸甲酯(缩写 MeJA)是一种挥发性有机物,用于植物防卫和许多不同的发育途径,如种子发芽、根的生长、开花、果实成熟与植物老化。它源自茉莉酸,由S-腺苷-L-甲硫氨酸:茉莉酸羧基甲基转移酶催化产生。

作用机制

当植物遭遇生物或非生物胁迫时(特别是食草生物或创伤),会生成茉莉酸和茉莉酸甲酯,并堆积在受损部位。茉莉酸甲酯会向植物的防御系统发出信号,也可以通过物理接触或空气传播,在未受损的植物中产生防御反应。未受损的植物可以通过气孔或叶细胞的细胞质扩散吸收空气中的茉莉酸甲酯,从而在遭受胁迫时产生茉莉酸甲酯,既用于内部防御又是向其他植物的信号传导化合物。
