Given that F and R had been previously evolved at different mutation rates (Table 1), we explored various genomic mutation rates (U), ranging 0.03 – 3. Also, to evaluate the stability of robustness, we recalculated it at the end of the run for each of the 50 populations evolved at U = 0.3.
This region includes the gene FRIGIDA, which is a major regulator of flowering time and which was previously identified to evolve under selection [ 2, 10].
We present an overview of the RNA processing cascade in the Eukaryotic Ancestor and investigate in particular, RNase MRP which was previously thought to have evolved later in eukaryotes due to its apparent limited distribution in fungi and animals and plants.
The genus was previously estimated to have evolved at least ca. 16 Mya ago based upon a published chronogram [ 7], although this may not represent the true age of the genus since the study included only five Pseuduvaria species (inclusive of C. phuyensis).
We consider a model of sympatric speciation due to frequency-dependent competition, in which it was previously assumed that the evolving traits have a very simple genetic architecture.
VP1 was previously demonstrated to have rapidly evolved [ 1].
The C-terminus of RUBISCO is involved in interactions between large subunits (intra-dimer) and with RUBISCO activase, and amino acid 472 was previously identified among rbcL residues evolving under positive selection [ 64].
The evolved clone BW4005 was previously characterized phenotypically by comparison to its ancestor, and exhibited a lower growth yield, a higher production of acetate from glucose in chemostat culture, and a lack of obvious difference in glucose uptake [ 28].
We addressed three key questions. 1) Do the plastomes of other cycad genera evolve slowly as was previously observed in the plastome of Cycas taitungensis?
The large brain evolved before flight earlier than was previously thought," Dr Balanoff told BBC News.
