Hydrangea bretschneideri Dipp is a highly popular ornamental plant for garden decoration. Genetic engineering
technology has been successfully used in many plant species, but it is limited in Hydrangea. Here we established
an efficient regeneration system by using stem segments as explants for the first time. In our study, the plant
growth regulators (PGRs) were evaluated at the different regeneration processes, including axillary shoots regeneration and root induction. We found that the optimal concentration for axillary buds’ induction was 2.0 mgL−1
6-BA and 0.5 mgL−1
1 IAA, its highest induction rate was 70%. Moreover, the highest axillary shoots proliferation
coefficient was 10.7 on the Murashige and Skoog (MS) medium with 2.0 mgL−1 6-benzyladenine (BA), 0.2 mgL−1
indole-3-butyric acid (IBA), and 1.0 mgL−1 gibberellin A3 (GA3). The highest frequency of root induction was
80.0 ± 0.06% by culturing the elongated shoots in 1/2 MS medium containing 0.1 mgL−1 IBA. In summary,
our study will provide an effective technology for large-scale propagation and important pathway for promoting
the popularization and application of Hydrangea bretschneideri Dipp. 相似文献

Background: The pandemic of novel coronavirus disease 2019 (COVID-19) has become a serious public health crisis worldwide. The symptoms of COVID-19 vary from mild to severe among different age groups, but the physiological changes related to COVID-19 are barely understood.Methods: In the present study, a high-resolution mass spectrometry (HRMS)-based lipidomic strategy was used to characterize the endogenous plasma lipids for cured COVID-19 patients with different ages and symptoms. These patients were further divided into two groups: those with severe symptoms or who were elderly and relatively young patients with mild symptoms. In addition, automated lipidomic identification and alignment was conducted by LipidSearch software. Multivariate and univariate analyses were used for differential comparison.Results: Nearly 500 lipid compounds were identified in each cured COVID-19 group through LipidSearch software. At the level of lipid subclasses, patients with severe symptoms or elderly patients displayed dramatic changes in plasma lipidomic alterations, such as increased triglycerides and decreased cholesteryl esters (ChE). Some of these differential lipids might also have essential biological functions. Furthermore, the differential analysis of plasma lipids among groups was performed to provide potential prognostic indicators, and the change in signaling pathways.Conclusions: Dyslipidemia was observed in cured COVID-19 patients due to the viral infection and medical treatment, and the discharged patients should continue to undergo consolidation therapy. This work provides valuable knowledge about plasma lipid markers and potential therapeutic targets of COVID-19 and essential resources for further research on the pathogenesis of COVID-19. 相似文献

纳米金属材料具有纳米晶强化效应、光吸收率大、较高的表面能和单磁畴性能等优点,因其在医药、化学催化、抗菌抑毒等方面发挥着越来越重要的作用而受到人们广泛关注。近年来,随着全球石化资源消耗与日俱增,环境污染加剧,基于可再生资源的生物基分子介导纳米材料的制备研究方兴未艾。生物基分子是指直接或间接来源于生物质的小分子或大分子物质,它们多数具有生物相容性好、低毒、可降解、来源广泛、价格低廉等优点。且由于生物基分子多数具有独特的理化性质,如具有生理活性的旋光性、酸碱两性、亲水亲油性以及易与金属离子络合等,其介导合成的纳米材料还兼具其独特功能性,比如消炎、抗癌、抗氧化、抗病毒以及降血糖血脂等,进一步拓宽了纳米金属材料的应用领域。文中对近年来基于生物基分子介导纳米金属材料的制备及应用进行全面综述,为开展相关研究提供参考。 相似文献
