  9. In fungi, aminoadipate reductase converts 2-aminoadipate to 2-aminoadipate 6-semialdehyde. However, other organisms have no homologue to the aminoadipate reductase gene and this pathway appears to be restricte...

    Citation: BMC Evolutionary Biology 2002 2:6
  10. The potential adaptive significance of transposable elements (TEs) to the host genomes in which they reside is a topic that has been hotly debated by molecular evolutionists for more than two decades. Recent g...

    Citation: BMC Evolutionary Biology 2002 2:5
  11. Phylogenetic relationships of the genus Hapalemur remains controversial, particularly within the Hapalemur griseus species group. In order to obtain more information on the taxonomic status within this genus, and...

    Citation: BMC Evolutionary Biology 2002 2:4
  12. Factors that affect flowering vary among different plant species, and in the grasses in particular the exact mechanism behind this transition is not fully understood. The brown midrib (bm) mutants of maize (Zea m...

    Citation: BMC Evolutionary Biology 2002 2:2
  13. Prior to this report, members of the inward rectifier family, or Kir, have been found only in eukaryotes. Like most K+ channels, the pore-forming part of the protein is formed by four identical, or closely relate...

    Authors: Stewart R Durell and H Robert Guy
    Citation: BMC Evolutionary Biology 2001 1:14
  14. Any DNA sequence is a result of compromise between the selection and mutation pressures exerted on it during evolution. It is difficult to estimate the relative influence of each of these pressures on the rate...

  16. Although closely related, the alpha-proteobacteria Wolbachia and the Rickettsiacae (Rickettsia and Ehrlichia), employ different evolutionary life history strategies. Wolbachia are obligate endocellular symbionts ...
