Based on this investigation, a model for the evolution of bZIP genes in green plants, based on four founder genes representing an ancestral tool kit, was established.
The ParaHox cluster, the hypothetical evolutionary sister of the Hox cluster [15], is also supposed to be part of this ancestral tool-kit, being implicated in endoderm patterning whereas Hox genes are more specifically expressed in ectoderm [16].
The finding that three major signaling pathways – MAPK, Wnt/GSK3 and BMP – are integrated at the level of Mad/Smad1/5/8 both in Drosophila and in the vertebrates has interesting implications for the evolution of animal forms through variations on an ancestral gene tool-kit [11].
Another tool implementing a new algorithm estimates admixture in each of a set of individuals relative to two or three assumed source (often called "ancestral") populations (tool #15).
The new findings, the Waters group reported, "suggest that although the ultimate ancestors of Clovis originated from northeast Asia, important technological developments, including the invention of the Clovis fluted points, took place south of the North American continental ice sheets before 13,100 years ago from an ancestral pre-Clovis tool assemblage".
We mapped the evolution of host-plant association, using the parsimony ancestral state reconstruction tool of Mesquite on the chronogram obtained with Multidivtime.
To properly reconstruct the history of GC3 evolution, it is needed to compare orthologous genes and to use appropriate and robust tools to reconstruct ancestral sequences, ancestral base compositions, and then finally obtain ancestral GC3 distributions.
The trustees argued that the numbers of dues-paying members and visitors to the society's library had plummeted as Internet-based research tools put ancestral records at the fingertips of anyone with a computer mouse.
Yes, the flowchart combines software analysis and manual means to construct a set of tools including alignments, ancestral ML reconstruction analyses, sequence logos and HMMs.
Current popular tools to infer ancestral genome data (such as GRAPPA and MGR) are all parsimony-based direct optimization methods with the aim to minimize the number of evolutionary events.
