菊科已被广泛研究，但只有3.5%的物种的基因组大小是已知的。为了扩大这些数据，我们进行了流式细胞术研究的核DNA含量在广泛的类群这个家庭，填补空白，在一些研究较少的群体。此外，还进行了一些染色体计数（46个分类群，包括两个种和一个亚种的第一个分类群）。我们提供了167个分类群（184加入）的基因组大小数据。其中新记录128种和亚种（141份），40属，3族（紫藤亚科、Gochnatieae和Nassauvieae）和2亚科（紫藤亚科和gochnatioideae）。大多数值（约75%）很小或非常小（1C3.5pg）。第二次报告17种以前研究的其他方法（即第一次流式细胞术评估）也给出了。最后，我们贡献了22个物种的第一个流式细胞术的评估结果已发表在本文的准备。目前的数据集将覆盖率的百分比从3%移动到4.7%，在特定级别，从6%到11.6%，在部落级别，从34.9%到41.9%，在亚科级别，从33%到50%。
The Asteraceae family has been broadly studied, but the values of genome size of only 3.5% of their species are known. To expand these data, we carried out a flow cytometric study of nuclear DNA content in a wide range of taxa of this family, filling gaps in some less studied groups. In addition, some chromosome counts have been performed (46 taxa, including the first one in two species and one subspecies). We provide genome size data for 167 taxa (184 accessions). Of these, data are new for 128 species and subspecies (141 accessions), 40 genera, three tribes (Barnadesieae, Gochnatieae and Nassauvieae) and two subfamilies (Barnadesioideae and Gochnatioideae). Most values (about 75%) are small or very small (1C3.5pg). The second reports on 17 species previously studied with other methods (i.e. first flow cytometric assessments) are also given. Finally, we contribute results for 22 species for which a first flow cytometric assessment has been published during the preparation of this article. The current data-set moves the percentage of coverage approximately from 3% to 4.7% at the specific level, from 6% to 11.6% at the generic level, from 34.9% to 41.9% at the tribal level and from 33% to 50% at the subfamily level.
