Hybridization followed by polyploidization has been recognized as an important mode of speciation in plants.In order to examine the origin of allopolyploidy,we studied nine extant species of Eleusine,a genus containing three allotetraploid species and showing substantial ecological and morphological diversity.Interspecific phylogenetic relationships of Eleusine and the allopolyploid origin of finger millet (E.coracana) were investigated using partial sequences from the nuclear genes Pepc4 and EF-1α.

MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are two classes of small regulatory RNAs derived from different types of precursors processed by distinct Dicer or Dicer-like (DCL) proteins.Duri
Aneuploidy,defined as losses or gains of individual chromosomes to the karyotype,has a greater impact on the phenotype than whole genome duplications (polyploidy) (1).This difference can be largely ex
A type of aneuploidy,trisomy,in which cells have an abnormal number of chromosomes (2n =2x+1),results in significant morbidity and mortality.The mechanisms by which the abnormal number (1.5 times) of
以国家二级保护植物永瓣藤(Monimopetalum chinense)为研究对象，采用半薄切片法研究花部形态结构，探究永瓣藤的结种率低和胚珠败育的成因。研究结果表明永瓣藤花粉发育基本正常，花粉的实验观察未见异常结构；子房上位(周位花)，子房由4心皮组成，心皮边缘相互合并成隔膜，向心室中心延伸，但没有在子房中央完全连合封闭，子房1室，胚珠4枚，但有胚珠不育，常常仅1-2枚发育成种子；永瓣藤的花器官
姜科植物花器官高度特化，传粉模式丰富多样，根据花粉外被的状态，花粉可分为粘液状，粘浆状和干性三种类型，而不同类型的花粉与传粉机制有关。本文选取的材料为花粉粘液状的黄花大苞姜(Caulokaempferia coenobialis)，花粉粘浆状的广西莪术(Curcuma kwangsinensis)，花粉干性的海南三七(Kaempferia rotunda)和红豆蔻(Alpinia galanga)
本研究以中国苜蓿属(Medicago L.)与胡卢巴属(Trigonella L.)植物共16种为研究对象,查阅并测量了全国8个重要标本馆所收藏的苜蓿属与胡卢巴属植物标本,应用数量分类方法,结合种皮特征和花粉形态观察,采用26个质量性状和14个数量性状进行了聚类分析和主成分分析,其结果将苜蓿属及与胡卢巴属分为4组：(1)一年生,花序短缩呈伞形或单生,无总花梗或具较短的总花梗,荚果圆柱形(即原葫芦巴
在衡量中国科学院植物研究所标本馆(PE)和华南植物所标本馆(IBSC)所有馆藏的中国杏属(Armeniaca Mill.)7个种2个变种植物标本性状特征的基础上，观测了14个数量性状和24个定性性状.主成分分析显示，性状的累积贡献率增长明显，前3个主成分累积贡献率达81.65％.结果显示叶柄直径、叶片光滑度、叶大小、核大小、果柄长短、核顶端、核表面纹饰等性状的信息负荷量最大，对杏属植物分类有作用，
