Measuring Auxin Transport Capacity in Seedling Roots of Medicago truncatula

[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 response to rhizobia inoculation. Similar assays could be adapted in other plant species and to answer other biological questions. [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。

High-throughput Method for Determination of Seed Paternity by Microsatellite Markers

[Abstract]  In this protocol, determination of seed paternity by microsatellite markers in Nicotiana attenuata is described. However, this does not include a protocol for the novel marker selection/identification, but rather exploits the markers generated for a closely related species N. tabacum (Bindler et al., 2007). This is a high-throughput protocol optimized and streamlined for one skilled person to process 384 (96 x 4) seeds in 5 days, from DNA isolation (from seedlings) to paternity assessment by microsatellite genotype data. [摘要]  在该方案中,描述了通过微卫星标记在烟草中确定种子亲子。 然而,这不包括新标记选择/鉴定的方案,而是利用为密切相关物种N产生的标记。 tabacum (Bindler ,2007)。 这是一种高通量方案,对于技术人员来说,优化和流线化以在5天内从微生物分离(从幼苗)到通过微卫星基因型数据的亲子鉴定来处理384(96×4)种子。
