A new synonym of Pellionia scabra Benth.

Based on the study of specimens from Hunan, and field observations in Hengshan (holotype locality of Pellionia cephaloidea W. T. Wang), Nanyue, Hunan, China, Pellionia cephaloidea W. T. Wang is regarded as a new synonym of Pellionia scabra Benth., and Pellionia Gaudich. sect. Elatostematopsis W. T. Wang as a new synonym of Pellionia Gaudich. sect. Pellionia.     

应恢复赤车属头序赤车组和头序赤车

头序赤车的特征在于其具花序托和总苞的雌头状花序,根据此一特征即可将它与赤车属的其它所有种区别开.因此,在2002年被错误归并为异名的此赤车属进化种,以及根据其建立的单种进化组头序赤车组在该文中予以恢复.     

蔓赤车的一个新异名

根据对产自湖南的蔓赤车Pelliona scabra Benth．标本的研究,结合在头序赤车P．cephaloidea W． t. Wang模式产地湖南南岳衡山的野外调查,发现头序赤车的模式标本是采自幼雌花序时期的蔓赤车,故将头序赤车作为蔓赤车的新异名,头序赤车组作为赤车组的新异名。     

赤车属(荨麻科)四种植物的订正

根据对赤车属植物标本的研究,将小赤车归并入短叶赤车,小异被赤车归并入异被赤车,海南赤车归并入滇南赤车,长茎赤车归并入赤车。     

应恢复赤车属头序赤车组和头序赤车

头序赤车的特征在于其具花序托和总苞的雌头状花序,根据此一特征即可将它与赤车属的其它所有种区别开。因此,在2002年被错误归并为异名的此赤车属进化种,以及根据其建立的单种进化组头序赤车组在该文中予以恢复。

Pelliolatifolias A-D,Four Undescribed Compounds from Pellionia latifolia Boerl. and Their Nitric Oxide Production Inhibitory Activity

Four undescribed compounds ( 1 – 4 ) named pelliolatifolias A−D together with seven known compounds trans-clovamide ( 5 ), N-trans-caffeoyl-4-hydroxyphenylalanine methyl ester ( 6 ), N-trans-caffeoyl-3,4-dihydroxyphenylalanine methyl ester ( 7 ), luteolin 4’-O-β-D-glucopyrannoside ( 8 ), cis-syringin ( 9 ), trans-syringin ( 10 ), and citroside A ( 11 ) have been isolated from the methanol extract of the Pellionia latifolia leaves. Their chemical structures were elucidated based on extensive analyses of HR-ESI-MS, 1D and 2D NMR, and CD spectra. Compounds 1 – 7 , 9 and 10 showed moderate inhibition of NO production in LPS-activated RAW264.7 cells with their IC₅₀ values ranging from 39.27 to 75.42 μM, compared to that of the positive control compound, dexamethasone, IC₅₀ value of 14.20 μM.

重庆荨麻科一新种——缙云赤车

在重庆市北碚区缙云山野外植物调查过程中,于海拔500～800 m的溪边阴湿沟谷中发现一种荨麻科植物,虽然该物种雌花序具花序托,但因其雌花花被片5枚,外面先端具角状突起,瘦果只具瘤状突起,更符合赤车属的特征,且结合分子系统学证据,该物种明显属于赤车属.该物种的特征在于其具花序托和总苞的雌花序,根据这一特征可将其置于头序赤...     

蔓赤车叶绿体基因组结构及系统进化分析

蔓赤车(Pellionia scabra)属于荨麻科赤车属,是一种具有高营养价值的优质野菜。本研究以蔓赤车为材料,基于高通量技术方法完成叶绿体基因组测序、组装注释、结构解析及构建系统发育树,以此深入研究蔓赤车叶绿体基因组特征。结果表明,蔓赤车叶绿体基因组大小为153220 bp,GC含量为36.4%,属于典型的四分体结构。共注释到130个基因,其中85个蛋白编码基因,37个转运RNA基因,8个核糖体RNA基因;其中,有15个基因包含1个内含子,2个基因包含2个内含子,rps12存在反式剪接情况。蔓赤车叶绿体基因组可分为光合作用(43个)、自我复制(64个)、其他编码蛋白(7个)以及未知功能(4个)4大类基因。蔓赤车叶绿体基因组共检测出51073个密码子,其中编码亮氨酸(Leu)的密码子占比最大,密码子偏向使用A和U两种碱基。检测到72个简单重复序列位点,其中有58个单核苷酸、12个二核苷酸、1个三核苷酸和1个四核苷酸4种不同类型的简单重复序列(simple sequence repeats,SSRs)。蔓赤车IRb/SSC边界存在ycf1基因扩张现象。系统进化树显示,蔓赤车(Pellionia scabra OL800583)与庐山楼梯草(Elatostema stewardii MZ292972)、盘托楼梯草(Elatostema dissectum MK227819)、光叶楼梯草(Elatostema laevissimum var.laevissimum MN189961)亲缘关系最密切。基于蔓赤车叶绿体基因组的研究,旨在为蔓赤车物种鉴定、遗传进化及基因组学研究奠定理论基础。     

中国赤车属新分类

(1)根据该文中赤车属与楼梯草属各种形态学的区别,认为赤车属较为原始,在楼梯草属之前自冷水花属衍生而出。(2)将赤车属划分为5组;将C.B.Robinson描述的Elatostemoides属降为组级群,作为赤车属中接近原始群全缘赤车组sect.Pileoides的一个组处理,此外还描述了一个与sect.Elatostemoides近缘的1新组,羽脉赤车组sect.Leiolaena,并根据叶、叶的脉序、雌花序、雌花被片和瘦果等器官的演化趋势给出显示赤车属属下诸群间亲缘关系的系统发育树。(3)对中国赤车属的属下分类群进行了修订,共承认32种1亚种7变种,给出检索表、描述及多幅插图,并将它们划分为4组、2亚组和9系,其中除sect.Leiolaena之外,还新描述了2亚组、5系、2种和3变种;在2003年被归并为同物异名的长柄赤车、曲毛赤车、波缘赤车、小赤车和富宁赤车的种级地位得到恢复。此外,还写出了中国赤车属的分类学简史和地理分布。
