[Abstract] Cannabis seed germination is an important process for growers and researchers alike. Many biotechnological applications require a reliable sterile method for seed germination. This protocol outlines a seed germination procedure for Cannabis sativa using a hydrogen peroxide (H2O2) solution as liquid germination media. In this protocol, all three steps including seed sterilization, germination, and seedlings development were carried out in an H2O2 solution of different concentrations; 1% H2O2 solution showed the fastest and the most efficient germination. This protocol also exhibited high germination efficiency for very old cannabis seeds with lower viability. Overall, this protocol demonstrates superior germination compared to water control and reduces the risk of contamination, making it ...
[摘要] [摘要]大麻种子的发芽对种植者和研究者都是重要的过程。许多生物技术应用需要可靠的无菌方法来发芽种子。该协议概述了使用过氧化氢（H 2 O 2 ）溶液作为液体发芽介质的苜蓿种子的发芽过程。在这种PROT ocol，所有三个步骤，包括种子消毒，发芽，和幼苗发育中进行了一个ħ 2 ö 2种不同浓度的溶液; 1％H 2 O 2 解决方案显示出最快，最有效的发芽。该协议还显示了对于具有较低生存能力的非常老的大麻种子的高发芽效率。总的来说，与水控制相比，该协议证明了更好的发芽能力，并降低了污染的风险，使其适合组织培养和其他敏感应用。
[背景技术]大麻，否则称为大麻或大麻，是其中男性/女性性别由异型染色体（X和Y）确定的年主要雌雄异株的开花植物（德特等人，2020）。大麻种植有多种农业用途。几乎所有大麻植物的部分都被使用，种子用作食物，茎用作纤维，花/叶用作药物。花会产生大麻素和芳香化合物的混合物，这些化合物因其治疗和娱乐作用而受到重视（Chandra等人，2017）。大麻植物通过插条或通过种子发芽而无性繁殖。种子萌发是研究人员，育种非常重要，而且种植者的喜爱，尤其是从优良品种的种子可能是非常昂贵的和有价值的。此外，较老的种子发芽率可能降低，而细菌和真菌污染会危害发芽，特别是在种子发芽进行组织培养繁殖时。为了解决这些问题，我们已经开发了一种快速，无菌，使用1％的过氧化氢（H，高效的种子萌发协议2 ...

[Abstract] Plant protein expression can be a challenging enterprise in any biochemical or molecular biology research project. Several heterologous systems like bacteria, yeast, insect cells and cell free systems have been used to produce plant proteins for in vitro experiments and structural characterization. However, due to particularities of plant proteins, for example the specific type and abundance of post-translational modifications (e.g. glycosylation), a plant system to express plant proteins is extremely desirable. The use of Nicotiana benthamiana (N. benthamiana) plants for protein expression has proven to be quick and reliable. To illustrate the robustness and rapidity of this system, recent efforts to produce the first protein based drug against the ...
[摘要] 植物蛋白表达可以是任何生物化学或分子生物学研究项目中的挑战性企业。几种异源系统如细菌，酵母，昆虫细胞和无细胞系统已被用于生产植物蛋白用于体外实验和结构表征。然而，由于植物蛋白的特殊性，例如翻译后修饰（例如糖基化）的特异性类型和丰度，表达植物蛋白的植物系统是非常需要的。已经证明使用本氏烟草（本生烟草）植物进行蛋白质表达是快速和可靠的。为了说明该系统的稳健性和快速性，最近在N中进行了生产针对埃博拉病毒的第一种基于蛋白质的药物的努力。本草案蛋白质表达系统（Choi等人，2015）。
该方案描述了一种简单的系统，用于表达和富集（亲和纯化） > N。本生烟草叶，其被成功地用于拟南芥果胶乙酰酯酶，PAE8和PAE9的表征中（de Souza等人，2014）。
