葡萄中糖基化花色苷研究进展 总被引:2,自引:0,他引:2
葡萄果实与葡萄酒的颜色由其所含花色苷的种类和含量决定,而花色苷是由花色素经过糖基化修饰转变而成,所以糖基化修饰在葡萄果实花色苷合成途径中起着重要作用。葡萄果实中的糖基化花色苷主要包括花色素的3–O–葡萄糖基和3,5–O–双葡萄糖基,即花色素单糖苷和花色素双糖苷,糖基化花色苷的组成是决定红葡萄酒品质的关键因素之一。对糖基化花色苷在葡萄果实中的组成及其对葡萄酒颜色和稳定性的影响进行了简要介绍,重点对花色素单糖苷和花色素双糖苷合成的关键酶基因以及转录因子进行了综述,以期为葡萄果实糖基化花色苷合成的调控机理的全面揭示和优质红色酿酒葡萄品种的选育提供信息。 相似文献

Salt stress has been applied to improve the quality of tomato, but detailed information about the changes in antioxidant systems in salt-stressed fruit is not available. In this study, we examined the effect of salt stress on oxidative parameters, antioxidant content and antioxidant enzymes in two tomato cultivars during two cropping seasons. Salt stress was applied by adding 100 mM NaCl to the nutrient solution. We show that tomato fruits have antioxidant systems to protect themselves from salt-induced oxidative stress. This finding is supported by the lipid peroxidation and hydrogen peroxide levels, which remained unchanged under salt stress conditions. However, these antioxidant systems depend on cultivars and cropping seasons. In the summer crop, the antioxidant systems in salt-stressed ‘House Momotaro’ can be attributed to the enzymatic reactions of ascorbate peroxidase (EC 1.11.1.11) and glutathione reductase (EC 1.6.4.2), while those in salt-stressed ‘Mini Carol’ can be attributed to their non-enzymatic reactions of ascorbate and glutathione. In the winter crop, the antioxidant systems were not influenced by salt stress in either cultivar. However, the proline content increased in both cropping seasons and cultivars. The seasonal and cultivar differences of salt-induced changes in the antioxidant systems may result from cultivar differences in antioxidant capacities and the interaction between salt stress and growth conditions such as temperature and solar radiation. 相似文献

Onions normally form bulbs in the first year of growth; however, exposure to low temperatures can induce flowering (vernalisation) before bulbs are produced. Based on the cultivation data of onions grown in Japan, we evaluated and validated a reported model describing the onion vernalisation response. The observed bolting rates of ‘Sapporoki’, which was used in the construction of a previous model, were a good fit to the model, whereas, the bolting rates of one of the overwinter-type cultivars, ‘Momiji No.3?, were lower than the predicted value. The difference between the predicted and observed bolting rates in ‘Momiji No.3? was caused by a larger VD0.5, the coefficient in vernalisation response models that represents the time point when half of the plants have bolted. Overwinter-type and/or bolting resistant cultivars can have parameters that indicate a further vernalisation requirement for bolting. The parameters in our model can be customised to the cultivar being investigated, and our study suggests the viability of modelling onion bolting by using air temperature. 相似文献
