Wheat RCA/Cpn60 pan-proteome: proteotype catalogue, audit tables and phylogenies across ten bread wheat cultivars

Derived datasets for a gene-locus-anchored catalogue of Rubisco activase (RCA) and chaperonin-60 (Cpn60) protein variation across ten sequenced bread wheat cultivars, built from Ensembl Plants annotated proteomes. Includes the non-redundant proteotype catalogue with composite identifiers and UniProt/InterPro annotation; the mapping of protein models to gene loci and chromosomes; presence–absence matrices; a recruitment-specificity audit; Cpn60 subunit classification by HMM profiling and reciprocal best hits, with an out-of-family negative control; cross-reference against an independent de novo annotation; divergence of reference-absent proteotypes from their nearest reference sequence; prevalence partitions at three clustering granularities; sequence-derived physicochemical descriptors; polymorphic-site tables; MAFFT alignments and FastTree phylogenies, raw and collapsed/outgroup-rooted, with a report of the rooting achieved per family; a prioritised candidate list; and the main and supplementary tables and figures. Every value quoted in the associated manuscript is read directly from these files. The build passed an automated consistency gate whose unedited output is included as 34_verification.txt.
