Evolution of Red Algal Plastid Genomes: Ancient Architectures, Introns, Horizontal Gene Transfer, and Taxonomic Utility of Plastid Markers
Red algal plastid genomes are easily obtainable using high-throughput sequencing of total genomic DNA, interesting from evolutionary perspectives, and promising in resolving red algal relationships at evolutionarily-deep and species/subspecies levels.
Organ and Cell Type–Specific Complementary Expression Patterns and Regulatory Neofunctionalization between Duplicated Genes in Arabidopsis thaliana
The evolutionary importance of reciprocal expression patterns between gene duplicates is indicated, showing that they are common, often associated with regulatory neofunctionalization, and may be a factor allowing for retention and divergence of duplicated genes.
Comparative analysis of structural diversity and sequence evolution in plant mitochondrial genes transferred to the nucleus.
A detailed portrayal of structural and sequence evolution in mitochondrial genes transferred to the nucleus is provided, revealing the frequency of different mechanisms for how presequences and introns are acquired and showing how the sequences of transferred genes evolve after movement between cellular genomes.
Comparative genomics of parasitic silkworm microsporidia reveal an association between genome expansion and host adaptation
It is demonstrated for the first time that the parasitic genomes can expand, instead of shrink, through several common molecular mechanisms such as gene duplication, horizontal gene transfer, and transposable element expansion.
Duplications and Turnover in Plant Genomes
An overview of how duplication-driven genomic turn-over has influenced the evolution and diversity of plant genomes is provided.
Comparative Genome Analysis Reveals Cyanidiococcus gen. nov., A New Extremophilic Red Algal Genus Sister to Cyanidioschyzon (Cyanidioschyzonaceae, Rhodophyta)
This strain is proposed to be a new genus and species, Cyanidiococcus yangmingshanensis, based on the genomic, morphological, and physiological traits, and it is suggested that the rbcL sequences of “G. maxima” deposited in GenBank correspond to misidentified isolates.

The crustose calcareous alga, Ramicrusta textilis Pueschel and G.W. Saunders (Peyssonneliaceae, Rhodophyta), was recently observed to overgrow dead and living corals in shallow lagoon patch reefs of…
Phylogeny, species diversity and biogeographic patterns of the genus Tricleocarpa (Galaxauraceae, Rhodophyta) from the Indo-Pacific region, including T. confertus sp. nov. from Taiwan
A molecular phylogeny of Tricleocarpa with an emphasis on Taiwan species and reassessed species diversity of the genus from the Indo-Pacific region based on analyses of rbcL and COI-5P sequences and morphological observations supported a trend that species in the T. fragilis group are restricted in their distribution to subtropical and tropical areas whereas species inThe cylindrica group have a wide distribution, ranging from temperate through to tropical areas.
SYSTEMATICS OF THE CALCIFIED GENERA OF THE GALAXAURACEAE (NEMALIALES, RHODOPHYTA) WITH AN EMPHASIS ON TAIWAN SPECIES 1
Molecular data do not support monophyly for the putatively pantropical species Galaxaura rugosa, Dichotomaria obtusata, and D. marginata, all of which are concluded are in need of taxonomic revision.
Dramatic change in function and expression pattern of a gene duplicated by polyploidy created a paternal effect gene in the Brassicaceae.
This study illustrates two dramatic examples of neofunctionalization following gene duplication by complete changes in expression pattern and function and indicates that paternal control of zygote elongation by SSP is an evolutionarily recent innovation in the Brassicaceae family.
