A Whole Chloroplast Genome Phylogeny of Diploid Species of Isoëtes (Isoëtaceae, Lycopodiophyta) in the Southeastern United States
TL;DR: This study is the first to resolve molecular-phylogenetic relationships in diploid Isoëtes from the southeastern USA and shows the utility of plastome sequences for unraveling relationships between closely related taxa.
Journal ArticleDOI
DNaseI-sensitive and undermethylated rDNA is preferentially expressed in a maize hybrid
TL;DR: Results from these single-base-pair mismatch hybridization experiments indicate that the majority of the rRNA transcripts in Sx19 orginate from the DNaseI-sensitive, undermethylated, Eco RI-polymorphic rDNA repeat units.
Journal ArticleDOI
Additional Support for Two Subgenera of Anemia (Schizaeaceae) from Data for the Chloroplast Intergenic Spacer Region trnL-F and Morphology
TL;DR: An analysis of morphological data for 13 species with 33 characters and molecular data for 14 species from the chloroplast DNA intergenic spacer region trnL-F indicates that species of the genus Anemia fall into two well-supported subgenera, Anemiorrhiza and Anemia.
Journal ArticleDOI

TL;DR: It is suggested that geographic differentiation of this important invasive species has occurred more often within pathways that regulate growth and response to defense and stress, which may be associated with survival in North America's diverse climatic regions.
Journal ArticleDOI
A phylogenomic approach resolves the backbone of Prunus (Rosaceae) and identifies signals of hybridization and allopolyploidy.
TL;DR: In this paper, the backbone of the genus Prunus, specifically the position of the racemose group relative to the solitary and corymbose groups, remains phylogenetically uncertain.
