Convergent Biochemical Pathways for Xanthine Alkaloid Production in Plants Evolved from Ancestral Enzymes with Different Catalytic Properties
Autor: Ruiqi Huang, Andrew J. O’Donnell, Todd J. Barkman, Jessica J. Barboline
Publikováno v: Molecular Biology and Evolution
Convergent evolution is widespread but the extent to which common ancestral conditions are necessary to facilitate the independent acquisition of similar traits remains unclear. In order to better understand how ancestral biosynthetic catalytic capab

Next-generation sequencing has resulted in an explosion of available data, much of which remains unstudied in terms of biochemical function; yet, experimental characterization of these sequences has the potential to provide unprecedented insight into

Publikováno v: American journal of human biology : the official journal of the Human Biology CouncilREFERENCES. 33(4)
Objectives Candidate gene methylation studies of NR3C1 have identified associations with psychosocial adversity, including war trauma. This pilot study (sample sizes from 22 to 45 for primary analyses) examined NR3C1 methylation in a group of Kenyan

Novel genetic code and record-setting AT-richness in the highly reduced plastid genome of the holoparasitic plant
Autor: Julia Naumann, Huei-Jiun Su, Todd J. Barkman, Samuel S. Jones, Weilong Hao, Jer-Ming Hu, Eric K. Wafula, Claude W. dePamphilis, Jeffrey D. Palmer, Elizabeth Skippington
Publikováno v: Proceedings of the National Academy of Sciences of the United States of America. 116(3)
Plastid genomes (plastomes) vary enormously in size and gene content among the many lineages of nonphotosynthetic plants, but key lineages remain unexplored. We therefore investigated plastome sequence and expression in the holoparasitic and morpholo

Phylogenetics of Dendrochilum (Orchidaceae) : Evidence of pronounced morphological homoplasy and predominantly centric endemism

Taxon, 86, 1173-1188
A phylogenetic hypothesis for the genus Dendrochilum s.l. (including Bracisepalum) is based on nucleotide sequences of the nuclear ribosomal ITS and two plastid regions (matK, ycf1). The trees based on parsimony analysis of the nrITS and plastid part

Convergent evolution of caffeine in plants by co-option of exapted ancestral enzymes
Autor: Ruiqi Huang, Andrew J. O’Donnell, Todd J. Barkman, Jessica J. Barboline
Publikováno v: Proceedings of the National Academy of Sciences. 113:10613-10618
Convergent evolution is a process that has occurred throughout the tree of life, but the historical genetic and biochemical context promoting the repeated independent origins of a trait is rarely understood. The well-known stimulant caffeine, and its

Nuclear and Chloroplast DNA Suggest a Complex Single Origin for the Threatened Allopolyploid Solidago houghtonii (Asteraceae) Involving Reticulate Evolution and Introgression
Autor: Todd J. Barkman, Pamela J. Laureto
Publikováno v: Systematic Botany. 36:209-226
Solidago houghtonii Torrey & A. Gray ex Gray is a federally threatened polyploid plant species likely of hybrid origin. Several hypothesized combinations of parental species have been suggested but none have been phylogenetically tested. Additionally
