DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.
DNA C值与被子植物入侵性密切相关,为考察应用DNA C值评估被子植物入侵性的可靠性和局限性,我们统计分析了全世界范围内3676种被子植物的DNA 1C值(配子未发生DNA复制时的染色体DNA含量)及基因组大小(单个染色体组的DNA 含量),结果表明:1)DNA 1C值和基因组大小在被子植物不同类群中差异极大,例如在草本植物中显著高于木本植物,单子叶植物显著高于双子叶植物,多年生植物显著高于非多年生植物;2)两项指标都与被子植物入侵性显著负相关,尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中,然而在木本植物、豆科植物中其与植物入侵性无显著关系。

In this work, we used the sequences of nuclear genes (ITS, Adh2, Adh3 and Waxy) and cpDNA (trnL-F and matK) to explore the origin of Elymus species and the Y genome, and to reveal the mechanism of the geographical differentiation of the StY-genome Elymus species.
本文通过核基因ITS、Adh和Waxy基因以及叶绿体基因trnL-F和marK的序列分析了披碱草属相关二倍体种的系统发育关系和披碱草属植物的起源。

The haploid plant produces gametes mitotically and is thus termed the gametophytes while the diploid plant produces spores meiotically and is called the sporophyte.
单倍体植物有丝分裂产生配子体,二倍体减数分裂产生孢子体。
