| 1 | Origins and evolution of plant diversity in the Hengduan Mountains, China显示文摘1.Introduction The Hengduan Mountains region(HDM)in southwest China,one of the earth's 34 biodiversity hotspots,is characterized by its unique geology,dramatic topography,a climate where snow and below freezing temperatures can occur on any day of the year,by its location at elevations averaging between(1400e)2000 and4500(e5300)meters above sea level(m a.s.l.),and by one of | Hang Sun Jianwen Zhang Tao Deng David E.

| 2 | The origin, diversification and adaptation of a major mangrove clade (Rhizophoreae) revealed by whole-genome sequencing显示文摘Mangroves invade some very marginal habitats for woody plants—at the interface between land and sea.Since mangroves anchor tropical coastal communities globally, their origin, diversification and adaptation are of scientific significance, particularly at a time of global climate change. In this study, a combination of single-molecule long reads and the more conventional short reads are generated from Rhizophora apiculata for the de novo assembly of its genome to a near chromosome level. The longest scaffold, N50 and N90 for the R. apiculata genome, are 13.3 Mb, 5.4 Mb and 1.0 Mb, respectively. Short reads for the genomes and transcriptomes of eight related species are also generated. We find that the ancestor of Rhizophoreae experienced a whole-genome duplication ~70 Myrs ago, which is followed rather quickly by colonization and species diversification. Mangroves exhibit pan-exome modifications of amino acid(AA) usage as well as unusual AA substitutions among closely related species. The usage and substitution of AAs, unique among plants surveyed, is correlated with the rapid evolution of proteins in mangroves. A small subset of these substitutions is associated with mangroves' highly specialized traits(vivipary and red bark) thought to be adaptive in the intertidal habitats. Despite the many adaptive features, mangroves are among the least genetically diverse plants, likely the result of continual habitat turnovers caused by repeated rises and falls of sea level in the geologically recent past. Mangrove genomes thus inform about their past evolutionary success as well as portend a possibly difficult future. | Shaohua Xu Ziwen He Zhang Zhang Zixiao Guo Wuxia Guo Haomin Lyu Jianfang Li Ming Yang Zhenglin Du Yelin Huang Renchao Zhou Cairong Zhong David E.

| 4 | Meconopsis wilsonii subsp.wilsonii (Papaveraceae) Rediscovered显示文摘Field studies in the Lamagetou Nature Reserve, Mianning Xian, Sichuan Province, in the summer of 2005 revealed a particularly rich and diverse flora. One particularly noteworthy plant growing in openings in the forest, at woodland margins and on exposed slopes, was the recently described Meconopsis wilsonii Grey-Wilson subsp.wilsonii (Papaveraceae), a species previously known only from the type collection and last collected in 1908, nearly 100 years ago. | Toshio YOSHIDA Hang SUN David E.
