Cotyledon Wounding of Arabidopsis Seedlings

[Abstract]  Damage to plant organs through both biotic and abiotic injury is very common in nature. Arabidopsis thaliana 5-day-old (5-do) seedlings represent an excellent system in which to study plant responses to mechanical wounding, both at the site of the damage and in distal unharmed tissues. Seedlings of wild type, transgenic or mutant lines subjected to single or repetitive cotyledon wounding can be used to quantify morphological alterations (e.g., root length, Gasperini et al., 2015), analyze the dynamics of reporter genes in vivo (Larrieu et al., ... [摘要]  通过生物和非生物损伤对植物器官的损害在自然界中是非常常见的。拟南芥(Arabidopsis thaliana)5天龄(5-do)幼苗代表了一种优异的系统,其中在损伤部位和远端无害组织中研究植物对机械创伤的反应。经受单次或重复子叶伤害的野生型,转基因或突变品系的幼苗可用于定量形态学改变(例如根长度,Gasperini等人,2015),分析体内报道基因的动力学(Larrieu等人,2015; Gasperini等人,2015),遵循定量的转录变化RT-PCR(Acosta等人,2013; Gasperini等人,2015)或通过大量下游程序检查伤口反应的其它方面。在这里我们说明如何快速,可靠地卷绕年轻幼苗的子叶,并显示两个启动子驱动表达的β-葡萄糖醛酸酶(GUS)在整个幼苗和主根根分生组织,单个或重复子叶伤害后的行为,分别。我们描述了可以容易地适应具体实验需要的两个程序。

Maize Embryo Transient Transformation by Particle Bombardment

[Abstract]  Particle bombardment has been shown to be a useful method to study gene promoter regulatory elements by transient transformation of maize embryos with different constructions of gene promoters fused to a gene reporter. DNA to transfer is coated to high density gold microparticles and introduced into cells when accelerated by a helium pulse. This method allows a first rapid approach, avoiding time consuming stable transformation of maize plants and also allows quantitative promoter expression analysis by a histochemical or fluorometric assay. [摘要]  已经证明粒子轰击是通过与基因报告基因融合的不同构建的基因启动子的玉米胚的瞬时转化来研究基因启动子调节元件的有用方法。 转移的DNA被涂覆到高密度的金微粒上,并通过氦脉冲加速时被引入细胞。 该方法允许第一快速方法,避免耗时的玉米植物的稳定转化,并且还允许通过组织化学或荧光测定进行定量启动子表达分析。
