Convergent adaptation of the genomes of woody plants at the land–sea interface

Sequencing multiple species that share the same ecological niche may be a new frontier for genomic *** such studies should shed light on molecular convergence, genomic-level analyses have been unsuccessful, due mainly to the absence of empirical controls. Woody plant species that colonized the global tropical coasts, collectively referred to as mangroves, are ideal for convergence studies. Here, we sequenced the genomes/transcriptomes of 16 species belonging in three major mangrove clades. To detect convergence in a large phylogeny, a CCS+ model is implemented, extending the more limited CCS method(convergence at conservative sites). Using the empirical control for reference, the CCS+ model reduces the noises drastically, thus permitting the identification of 73 convergent genes with Ptrue(probability of true convergence) > 0.9. Products of the convergent genes tend to be on the plasma membrane associated with salinity tolerance. Importantly, convergence is more often manifested at a higher level than at amino-acid(AA) sites. Relative to >50 plant species, mangroves strongly prefer 4 AAs and avoid 5 others across the genome. AA substitutions between mangrove species strongly reflect these tendencies. In conclusion, the selection of taxa, the number of species and, in particular, the empirical control are all crucial for detecting genome-wide convergence. We believe this large study of mangroves is the first successful attempt at detecting genome-wide site convergence.

Mangroves invade some very marginal habitats for woody plants—at the interface between land and *** 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 duplication70 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.

青藏高原东南缘是检验青藏高原演化模型的理想实验场,也是全球地震活动最为频繁的地区之一.综述了青藏高原东南缘主要活动断裂十年和万年尺度的滑动习性研究和百年时间尺度区域地震活动分布,结合前人总结的百万年时间尺度的年代学研究,认为自中新世中晚期以来,青藏高原内部物质逐渐向东流出,受四川盆地阻挡,转而向东南缘地区作顺时针旋转运动,至晚第四纪时期,东南缘地区上地壳变形已由原本集中分布在大型走滑边界断裂和逆冲褶皱带转变为弥散式分布至区内次级断裂,形成了以鲜水河-小江断裂带和实皆断裂带为边界,围绕喜马拉雅东构造结作顺时针旋转的运动学特征.据此青藏高原东南缘变形可划分为两阶段,中新世早期及以前变形集中在大型边界断裂,符合刚性块体变形,至晚第四纪时期转为弥散式连续变形.基于水平滑动速率和地震活动性对比,青藏高原东南缘活动断裂可大致分为三级.一级断裂为边界断裂鲜水河-小江断裂带和实皆断裂带,水平滑动速率均≥10 mm/a,曾发生8级及以上地震和连续的7~7.9级强震,是东南缘地区晚第四纪以来一级构造格架;二级断裂往往控制东南缘地区强活动构造单元,水平滑动速率为~3~6 mm/a,通常发生过7~7.9级地震;三级断裂水平滑动速率一般≤2 mm/a,通常发生过7级以下地震,一般规模较小,但数量较多.此外,川滇地块晚第四纪变形特征发生转变,构造运动由原本的沿大型边界走滑断裂运动转变为鲜水河-小江断裂带周缘次级活动地块的旋转、平移和差异隆升.
