Key findings
155 rice and 197 Arabidopsis MYB genes; R2R3 is the largest subclass.
Methodology
Identified/classified MYB genes genome-wide and analyzed structures plus expression.
Limitations
Classification is sequence-based; not every gene’s phenotype is functionally validated here.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Plant MYB inventories are also sequence phylogenies: 155 rice and 197 Arabidopsis MYB genes, with R2R3 the largest subclass. Structure and expression were analysed, but classification remains sequence-based rather than a phenotype for every gene.
Evidence for the claim as stated.
These papers do not build the same kind of tree. HSP90 and MYB papers classify gene families; the immune-gene paper scans orthologs for repeated positive selection (~14% selected in all tests); Aspergillus and Listeria papers mix clade phylogeny with pan-genome gene content; turtle and Medicago papers are organismal genomes whose phylogeny is background for physiology or breeding. A student who treats every 'phylogenetic analysis' hit as a species tree will misread the result.
