Substitution rate comparisons between grasses and palms: synonymous rate differences at the nuclear gene Adh parallel rate differences at the plastid gene rbcL.
TLDR
It is reported that palm sequences evolve at a rate of 2.61 x 10(-9) substitution per synonymous site per year, a rate which is slower than most plant nuclear genes, and synonymous rates in nuclear Adh genes show a marked decrease in palms relative to grasses, paralleling the pattern found at the plastid rbcL locus.

  • Journal of Molecular Evolution
  • 1 September 1993
TLDR
Codon use in the three sequenced chloroplast genomes (Marchantia, Oryza, and Nicotiana) is examined and it is suggested that selection is acting on the codon use of this gene to adapt codons to tRNA availability, as previously suggested for unicellular organisms. Expand
A Catalogue of the Living Marine Bivalve Molluscs of China
This is a comprehensive catalogue of the living marine Bivalvia of China. Over 1,140 species are arranged in systematic order reflecting the phylogenetic relationships of the supraspecific taxa,Expand
RECONSTRUCTION OF THE EVOLUTION OF REPRODUCTIVE CHARACTERS IN PONTEDERIACEAE USING PHYLOGENETIC EVIDENCE FROM CHLOROPLAST DNA RESTRICTION‐SITE VARIATION
TLDR
The results indicate that the class of optimization scheme used was the most critical factor in reconstructing character evolution, and several broad conclusions were possible when an unordered, unequally‐weighted optimization scheme was used. Expand
Evolution of alcohol dehydrogenase genes in the palm and grass families.
TLDR
Comparison of the Adh gene families from palms and grasses shows that theadh1 and adh2 genes of grasses, and the adhA andadhB genes of palms, arose by duplication following the divergence of the two families. Expand
Some Aspects of the Biology, Population Dynamics, and Functional Morphology of Musculista senhausia Benson (Bivalvia, Mytilidae)
TLDR
The European dreissenid Dreissena po/ymorpha and the Asian mytilid Limnoperna forlunei have both adopted a mode of life involving the colonization of hard surfaces in fresh waters, which must have enabled the ancestors of modern-day species initially to colonize the intertidal zone. Expand
Morphological and mitochondrial-DNA analysis of the Indo-West Pacific rock oysters (Ostreidae: Saccostrea species)
TLDR
Phylogenetic analyses using partial mitochondrial 16S DNA sequences of approximately 513 base pairs identified two clades that correspond to superspecies, i.e. S. cucullata and S. mordax, comprising nine and two lineages from the Indo-West Pacific, respectively. Expand
