The first inversion is common in papilionoid legumes indicating an early split in the diversification of papilionoid members.
In plants, LRR-RLKs show a pattern of expansion with amplification/deletion and evolution of domain organization leading to the functional diversification of the members of the gene family [ 1].
In plants, the exon/intron diversification of gene family members has played an important role in the evolution of multiple gene families [ 51].
These data lend further support to the hypothesis that the diversification of Aux/IAA family members in flowering plants has been sustained by changes in their expression patterns.
Our results reveal an intriguing story of ancient origin, duplication and diversification of stomatin family members and identifies candidate organisms that should be used when attempting to understand stomatin function outside of primate systems.
In fact, exon/intron diversification of gene family members has played an important role in the evolution of multiple gene families through three main types of mechanism: exon/intron gain/loss, exonization/pseudoexonization, and insertion/deletion [ 51].
Often, the expansion of gene families through gene creation results in functional diversification of gene family members, a process sometimes associated with rapid evolutionary changes at the DNA sequence and spatio-temporal expression levels.
The pioneering study of [ 30] provided a paradigmatic case of duplication and transcriptional diversification in members of the stilbene synthase gene family in grapevine.
Is there diversification of function among family members or does one member play a major role and functional redundancy exists among family members?
Our analyses of the phylogeny and expression of the largest RMP multi-gene family, the pirs, indicates functional diversification between members of the pir multigene family (this gene family is conserved between human/primate and RMP malaria species).
