[Abstract]  Verticillium dahliae is a soil-borne phytopathogenic fungus that infects host roots and proliferates in vascular tissues. The great loss of economically important crop caused by V. dahliae has raised worldwide concern, however, little is known about the mechanism of its pathogenicity (Klosterman et al., 2011; Yadeta and Thomma, 2013). Our recent work has shown that V. dahliae develops hyphopodium as an infection structure to breach plant root cell wall (Zhao et al., 2016). Here, we provide a detailed protocol to analyze the penetration ability and ... [摘要]  大丽轮枝菌属是土壤传播的植物病原真菌,其感染宿主根并在血管组织中增殖。经济上重要的作物造成的巨大损失。大丽花已经引起了全世界的关注,然而,其致病性机制知之甚少(Klosterman等人,2011; Yadeta和Thomma,2013)。我们最近的工作表明,大丽花开发hyphopodium作为感染结构以破坏植物根细胞壁(Zhao等人,2016)。在这里,我们提供了一个详细的方案来分析渗透能力和致病性。大丽花,以及从以前的研究(Zhang等人,2016a和2016b; Zhao等人,2016年)开发的感染棉花茎中恢复真菌菌丝)。玻璃纸膜已被用于诱导叶面病原体的发育,而不是根系病原体(Bourett和Howard,1990)。我们采用玻璃纸膜的方法诱导和评估hyphopodium的发展。希望能大力促进调控传染性发育的宿主的分子生物学研究。该协议还有助于识别控制V的致病性的关键成分。大丽花,并扩大了我们对植物与微生物相互作用机理的理解。

背景 玻璃纸膜被广泛用于研究叶病原体感染结构的发展(Bourett和Howard,1990; Kleemann等人,2012; Gu等人, ...

[Abstract]  Measurement of auxin transport capacity provides quantitative data on the physiological machinery involved in auxin transport within plants. This technique is easy to perform and gives quick results. Radiolabelled auxin (indole-3-acetic-acid) is fed into the roots of Medicago truncatula via an agar block. The resulting radioactivity from radiolabelled auxin uptake in the roots is measured with a liquid scintillation counter. Here, we describe the measurement of auxin transport capacity around the nodulation susceptible zone in young seedling roots of M. truncatula in ... [摘要]  生长素运输能力的测量提供了涉及植物中生长素运输的生理机制的定量数据。 这种技术很容易执行,并给出快速的结果。 将放射性标记的生长素(吲哚-3-乙酸)通过琼脂块加入到Medic藜苜蓿的根部。 使用液体闪烁计数器测量根中放射性标记的生长素摄取的最终放射性。 在这里,我们描述了生长素运输能力周围的结瘤敏感区在年轻幼苗根的测量。 truncatula 响应根瘤菌接种。 类似的测定可以适用于其他植物物种并回答其他生物学问题。

Visualization of Intracellular Tyrosinase Activity in vitro

[Abstract]  Melanocytes produce the melanin pigments in melanosomes and these organelles protect the skin against harmful ultraviolet rays. Tyrosinase is the key cuproenzyme which initiates the pigment synthesis using its substrate amino acid tyrosine or L-DOPA (L-3, 4-dihydroxyphenylalanine). Moreover, the activity of tyrosinase directly correlates to the cellular pigmentation. Defects in tyrosinase transport to melanosomes or mutations in the enzyme or reduced intracellular copper levels result in loss of tyrosinase activity in melanosomes, commonly observed in albinism. Here, we describe a method to ... [摘要]  黑素细胞在黑素体中产生黑色素,这些细胞器保护皮肤免受有害的紫外线。 酪氨酸酶是使用其底物氨基酸酪氨酸或L-DOPA(L-3,4-二羟基苯丙氨酸)引发颜料合成的关键铜酶蛋白酶。 此外,酪氨酸酶的活性与细胞色素沉着直接相关。 酪氨酸酶转运到黑素体中的缺陷或酶中的突变或降低的细胞内铜水平导致黑素体中酪氨酸酶活性的丧失,通常在白化病中观察到。 在这里,我们描述了一种方法来检测小鼠黑素细胞中酪氨酸酶的细胞内活性。 该协议将使存在于细胞内囊泡或细胞器(包括黑素体)中的活性酪氨酸酶可视化。
