1Recent advances on phylogenomics of gymnosperms and a new classification显示文摘Living gymnosperms comprise four major groups:cycads,Ginkgo,conifers,and gnetophytes.Relationships among/within these lineages have not been fully resolved.Next generation sequencing has made available a large number of sequences,including both plastomes and single-copy nuclear genes,for reconstruction of solid phylogenetic trees.Recent advances in gymnosperm phylogenomic studies have updated our knowledge of gymnosperm systematics.Here,we review major advances of gymnosperm phylogeny over the past 10 years and propose an updated classification of extant gymnosperms.This new classification includes three classes(Cycadopsida,Ginkgoopsida,and Pinopsida),five subclasses(Cycadidae,Ginkgoidae,Cupressidae,Pinidae,and Gnetidae),eight orders(Cycadales,Ginkgoales,Araucariales,Cupressales,Pinales,Ephedrales,Gnetales,and Welwitschiales),13 families,and 86 genera.We also described six new tribes including Acmopyleae Y.Yang,Austrocedreae Y.Yang,Chamaecyparideae Y.Yang,Microcachrydeae Y.Yang,Papuacedreae Y.Yang,and Prumnopityeae Y.Yang,and made 27 new combinations in the genus Sabina.Yong Yang David Kay Ferguson Bing Liu Kang-Shan Mao Lian-Ming Gao Shou-Zhou Zhang Tao Wan Keith Rushforth Zhi-Xiang Zhang 2022Plant Diversity2022,44,4:10
2The MRE11 GAR motif regulates DNA double-strand break processing and ATR activation显示文摘MRE11/RAD50/NBS1 建筑群是很快招募到 DNA 双海滨裂缝(DSB ) 的主要传感器。MRE11 被知道是由在它的 glycine-arginine-rich (长嘴硬鳞鱼) 以内的 PRMT1 的精氨酸 methylated 主题。在这研究,我们报导在 GAR 主题与离氨酸代替精氨酸并且产生 MRE11 缺乏 methylated 精氨酸的 RK 蛋白质。Mre11 RK/RK 老鼠对 γ 过分敏感;照耀(红外) 和从这些老鼠的房间显示了房间周期检查点缺点和染色体不稳定性。而且, Mre11 RK/RK MEF 展出了在 RPA 和 RAD51 的招募表明缺点和缺陷到损坏地点的 ATR/CHK1。M RK 形成的 RN 建筑群并且对 DNA 损坏并且通常的地点局部性响应红外激活 ATM 小径。M RK RN 建筑群在为响应红外在 vivo 观察的损害 DNA 结束切除术和 ATR 激活负责的 vitro 展出了 exonuclease 和 DNA 有约束力的缺点。我们的调查结果在 DSB 修理为 MRE11 长嘴硬鳞鱼主题的关键角色提供基因证据,并且在 MRE11 长嘴硬鳞鱼表明在 translational 以后修正之间的一个机械学的连接主题并且 DSB 处理,以及发信号的 ATR/CHK1 检查点。Zhenbao Yu Gillian Vogel Yan Coulombe Danielle Dubeau Elizabeth Spehalski Josee Hebert David O Ferguson Jean Yves Masson Stephane Richard 2012Cell Research2012,22,2:5
3主成分分析法在壳斗科植物化石鉴定中的应用显示文摘壳斗科化石是北半球新生代地层的优势分子,然而由于其属种众多,叶片属种间特异性不明显,该科叶片化石的鉴定是古植物学研究的难点之一。面对化石标本不完整的性状特征信息,如何剔除冗余特征,重点考虑具有鉴定意义的标本特征,就显得非常必要。本研究通过调研多种降维算法,考虑到植物特征编码及赋值的数值特性,选用主成分分析法,以壳斗科青冈亚属植物叶片为例,对可能在化石叶片上观察到的22个性状特征(变量)进行降维处理,挑选出对于壳斗科化石叶片分类鉴定起主要作用的10个性状特征,并将其应用于化石鉴定进行验证。结果表明,仅考虑经过主成分分析法压缩挑选的10个主要性状特征,仍然能够实现壳斗科化石植物的准确鉴定。主成分分析法应用于壳斗科性状特征的降维处理效果良好,剔除冗余特征对标本鉴定结果没有影响。贾慧 孙柏年 David Kay Ferguson 孟祥宁 2017古生物学报2017,36,4:3
4Pollen dispersal in a mountainous area based on pollen analysis of four natural trap types from Lugu Lake, southwest China显示文摘从四的 24 件样品的 Palynological 分析自然花粉陷井打字(卢古·莱克底部沉积,表面土壤,吠叫样品,和苔藓垫子)在在来自卢古·莱克区域的不同高度的四个地点,西南中国,被承担了在一个多山的区域调查花粉疏开和免职并且帮助石块花粉分析的解释。在在卢古·莱克区域的 palynological 集合和现代植被之间的详细比较被执行了。在在不同垂直 vegetational 地区的花粉集合和植被之间的关联的初步的解释能被主要 taxa 的百分比认出,并且大多数除了 Pinus 的花粉 taxa 被期望未被充分代表。异国情调的花粉谷物能被风离开多于 70km 在山上搬运。当重建时, Upslope 或花粉谷物的下坡的运输是关键的在多山的区域的 palaeoclimate。我们总结谷物在三个地点是其花粉在场的现代木质的植物的高度的分布,并且表明花粉谷物是更多的乐意地带的登高比下坡。这些调查结果在多山的区域和 palaeoelevations 的 interpretion 关于植被的重建有重要含意。Su-Ping LI Ya-Qin HU David Kay FERGUSON Jian-Xin YAO Cheng-Sen LI 2013Journal of Systematics and Evolution2013,51,4:2

16Pollen morphology in Saxifraga(Saxifragaceae) from Ny-Alesund, Svalbard, Arctic, and its taxonomic significance显示文摘Pollen morphology of eight species of Saxifraga,i.e.S.cespitosa,S.oppositifolia,S.cernua,S.nivalis,S.aizoides,S.rivularis,S.hieraciifolia,and S.hirculus,collected from Ny-Alesund,Svalbard,Arctic was examined using light and scanning electron microscopy.Pollen grains of Saxifraga species are subprolate or prolate,3-colpate,15.4–44.4μm in the polar axis,11.4–34.6μm in the equatorial axis,and show a P/E ratio 1.19–1.40.On the basis of exine ornamentation,four pollen types,viz.,the S.oppositifolia type(striate without scabrae on the muri),S.cernua type(striate with scabrae on the muri),S.nivalis type(microreticulate and operculum absent),and S.cespitosa type(microechinate and operculum present),were recognized.Hierarchical cluster analysis of the pollen morphological characters indicated that pollen morphology supports the infrageneric classification of the genus Saxifraga.YAO Yifeng Bera Subir Ferguson David Kay LI Chengsen 2014Advances in Polar Science2014,25,2:1
