摘要

早些时候，我们已经确定，欧洲21点，在许多文学资料中被称为入侵的北美鬼针虫，早在1895年就被卡尔·沃恩斯托夫描述为决策者B.decipiens，并具有杂交起源（B.frondosa×B.cernua）。在这项研究中，我们继续通过分子遗传学和细胞学方法比较了B.connata和B.decipiens的基因组。这些物体是2018年从明尼苏达州和威斯康星州（美国）采集的B.frondosa、B.connata和B.cernua的F1后代，它们是在俄罗斯科学院Tsitsin主植物园的温室条件下从种子中生长出来的，以及从东欧（白俄罗斯和欧洲-俄罗斯）采集的B.decipiens、B.frondosa和B.cernua样本。研究了细胞核（ITS 1–2）和叶绿体（trnL–trnF和rpl32–trnL）DNA的核苷酸序列。对ITS 1–2位点的分析表明，北美的B.connata个体不是杂交种。叶绿体DNA区域的分析证实，两个分类群，B.connata和B.decipiens，在进化上都与B.cernua接近。孟加拉国植物分类学杂志。28（1）：2021年6月1日至10日

Molecular evidence for the status of Bidens connata Muhl. ex Willd. and B. decipiens Warnst. in the old and new World

Earlier, we have established that the European blackjack, which in many literary sources is cited as an invasive North American Bidens connata, was described by Carl Warnstorf back in 1895 as B. decipiens and had a hybrid origin (B. frondosa × B. cernua). In this study, we continue to compare the genomes of B. connata and B. decipiens by molecular genetics and cytological methods. The objects are the F1 offsprings of B. frondosa, B. connata, and B. cernua collected in 2018 from Minnesota and Wisconsin (USA), grown from seeds in the greenhouse conditions of N.V. Tsitsin Main Botanical Garden of Russian Academy of Sciences, as well as samples of B. decipiens, B. frondosa and B. cernua collected from Eastern Europe (Belarus and European Russia). The nucleotide sequences of nuclear (ITS 1–2) and chloroplast (trnL– trnF and rpl32–trnL) DNA were studied. Analysis of the ITS 1–2 site showed that B. connata individuals of North America are not hybrids. Analysis of the chloroplast DNA regions confirmed that both taxa, B. connata and B. decipiens, are evolutionarily close to B. cernua. Bangladesh J. Plant Taxon. 28(1): 1-10, 2021 (June)

期刊介绍： Bangladesh is a humid, subtropical country favouring luxuriant growth of microorganisms, fungi and plants from algae to angiosperms with rich diversity. She has the largest mangrove forest of the world in addition to diverse hilly and wetland habitats. More than a century back, foreign explorers endeavoured several floral expeditions, but little was done for non-vasculars and pteridophytes. In recent times, Bangladesh National Herbarium has been carrying out taxonomic research in Bangladesh along with few other national institutes (e.g. Department of Botany of public universities and Bangladesh Forest Research Institute).
