Foliar endophyte diversity in Eastern Asian-Eastern North American disjunct tree species - influences of host identity, environment, phylogeny, and geographic isolation

FRONTIERS IN PLANT SCIENCE, 14.

By: W. Zhou n, W. Shi n, P. Soltis*, D. Soltis* & Q. Xiang n

author keywords: allopatric divergence; Cornus; comparative analyses; foliar endophytic community; fungal ITS; bacterial 16S rDNA; phylogeny; alpha and beta diversity

Rediscovery of the lost little dogwood Cornus wardiana (Cornaceae)-Its phylogenetic and morphological distinction and implication in the origin of the Arctic-Sino-Himalayan disjunction

JOURNAL OF SYSTEMATICS AND EVOLUTION, 59(2), 405–416.

By: E. Wahlsteen*, W. Zhou n, Q. Xiang n & K. Rushforth

author keywords: circumboreal-Himalayan disjunction; Cornus; morphometry; new species; phylogeny

author keywords: eastern Asia&#8211; eastern North America; floristic disjunction; molecular evolution; species richness anomaly
MeSH headings : Asia; Evolution, Molecular; Asia, Eastern; North America; Phylogeny; Transcriptome

Characterization of the sequence and expression pattern of LFY homologues from dogwood species (Cornus) with divergent inflorescence architectures

Annals of Botany, 112(8), 1629–1641.

Contributors: J. Liu n, R. Franks n, C. Feng n, X. Liu, C. Fu* & Q. Xiang n

author keywords: Cornus; dogwood; inflorescence evolution; LFY homologues; CorLFY expression; RTPCR; in situ hybridization
MeSH headings : Amino Acid Sequence; Base Sequence; Cornus / anatomy & histology; Cornus / genetics; Cornus / growth & development; Exons / genetics; Gene Expression Regulation, Developmental; Gene Expression Regulation, Plant; Genes, Plant; In Situ Hybridization; Inflorescence / anatomy & histology; Inflorescence / genetics; Inflorescence / growth & development; Molecular Sequence Data; Phylogeny; Plant Proteins / chemistry; Plant Proteins / genetics; Plant Proteins / metabolism; Sequence Homology, Amino Acid
TL;DR: A role for CorLFY genes during floral and inflorescence development in dogwoods is suggested, however, the failure to detect expression differences between the inflorescence types in the Cornus species analysed suggests that the evolutionary shift between major inflorescencetypes in the genus is not controlled by dramatic alterations in the levels of CorL FY gene transcript accumulation.

Inferring the biogeographic origins of inter-continental disjunct endemics using a Bayes-DIVA approach

By: A. Harris*, J. Wen* & Q. Xiang n

author keywords: arcto-Tertiary; biogeography; disjunction; endemic species; Northern Hemisphere; RASP; S-DIVA; temperate forest
TL;DR: Bayes‐DIVA analysis is used to reconstruct the stem lineage distributions for 185 endemic lineages from 23 disjunct genera representing 17 vascular plant families and shows that eastern Asian endemics more often evolved from endemic ancestors compared to endemICS in Europe and eastern and western North America.

Microsatellite analysis of a broad hybrid zone in Aesculus (Sapindales) – Inferences in genetic structure and evolution

International Journal of Plant Sciences, 169(5), 647–657.

By: D. Thomas n, A. Ahedor n, C. Williams n, C. DePamphilis n, D. Crawford n & Q. Xiang*

author keywords: aesculus; hybrid zone; ISSR; long-distance gene flow; microsatellites
TL;DR: The data from this study and previous allozyme and chloroplast DNA studies indicate that both historical localized gene flow and recurrent long‐distant gene flow have contributed to the existence of the hybrid zone, that is, its origin via historical localized genes flow, while its maintenance involves ongoing long‐distance pollen dispersal.

TL;DR: It is inferred that Aesculus originated during the transition from the Cretaceous to the Tertiary (~65 M.Y.B.P.) at a high latitude in eastern Asia and spread into North America and Europe as an element of the “boreotropical flora”; the current disjunct distribution of the genus resulted from geological and climatic changes during theTertiary.

TL;DR: The cpDNA restriction site data correlate closely with the evolution of chromosome number, morphology, and phytochemistry, and most notably, the chromosome number of n = 10 evolved twice in Cornuis, and the small, non-petaloid bracts in C. disciflora apparently represent a reversal to the non-showy state.

Annals of the Missouri Botanical Garden, 80(3), 528.

By: M. Chase n, D. Soltis n, R. Olmstead n, D. Morgan n, D. Les n, B. Mishler n, M. Duvall n, R. Price* ...

TL;DR: Two exploratory parsimony analyses of DNA sequences from 475 and 499 species of seed plants, respectively, representing all major taxonomic groups indicate that rbcL sequence variation contains historical evidence appropriate for phylogenetic analysis at this taxonomic level of sampling.
