[Abstract]  Embryogenic suspension cultures of Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae) can be used as a model to test the effects of compounds added to the culture medium on the cellular growth and morphology of Pro-Embryogenic Masses (PEMs). PEMs are formed by embryogenic and suspensor-type cells. To measure changes in the cellular growth of embryogenic cultures, we performed sedimented cell volume (SCV) quantification, which is a non-destructive method. Morphological analysis by microscopy allowed for the observation of growth and development of PEMs and the alterations in ... [摘要]  可以使用南洋杉(Araucaria angustifolia)(Bertol。)Kuntze(Araucariaceae)的胚胎悬浮培养物作为模型来测试添加到培养基中的化合物对前胚胎形成质量的细胞生长和形态的影响PEM)。 PEM由胚胎形成和悬浮细胞形成。为了测量胚胎发生培养物的细胞生长的变化,我们进行沉降细胞体积(SCV)定量,其是非破坏性方法。通过显微镜进行的形态学分析允许观察PEM的生长和发育以及胚胎形成和悬浮体型细胞的改变。这里使用的方法提供了一个有效的手段监测PEM的细胞生长和识别胚胎发育培养发展过程中的形态变化。这些研究还可以与生物化学和分子分析例如蛋白质组学结合,以进一步研究胚胎生长和形态。

[Abstract]  The protoplasts assay constitutes a powerful tool that allows an easy uptake of active agents and a precise quantification of cell death induction in different populations. Our study showed that the basal level of cell death in our controls is low and stable throughout the length of our experiments (Danon et al., 2005; Pineau et al., 2013). In addition, the data obtained from the protoplast assay are applicable to intact seedlings, where it is possible to see differences in the intensity of necrotic lesions (Danon et al., 2006) even if those differences are not as ... [摘要]  原生质体测定构成了一种强有力的工具,其允许活性剂的容易摄取和在不同群体中细胞死亡诱导的精确量化。 我们的研究表明,我们的对照中的细胞死亡的基础水平低并且在整个实验的长度上是稳定的(Danon等人,2005; Pineau等人, 2013)。 此外,从原生质体测定获得的数据适用于完整的幼苗,其中可以看到坏死损伤强度的差异(Danon等人,2006),即使这些差异不是 如同原生质体测定一样容易和清楚地定量。
