matK_BOLD databases : 

This databases contain the sequences of the Maturase K gene (matK) of plants 
located in :
- matK_BOLD_Landes : the Landes de Gascogne Regional Nature Park (PNR des Landes de Gascogne).
- matK_BOLD_Arcachon : the Landes forest, located south of Arcachon Bay, France.

Sequences were extracted from the BOLD Public Record Barcode Database using 
the R package bold (Dubois S, Chamberlain S (2023), 
https://CRAN.R-project.org/package=bold, , v.1.3.0) based on species names.

Related taxonomy were extracted from NCBI using the R package taxize
(Scott Chamberlain and Eduard Szocs (2013), 
https://f1000research.com/articles/2-191/v2, v.0.9.1) considering only 
the "valid" plant names when available.
Ranks selected : Kingdom; Phylum; Class; Order; Family; Genus; Species

#    matK_BOLD_Landes 
All plant species present in the region were considered. This included both 
"valid" and "invalid" species names recorded by the French National Natural 
Heritage Inventory (INPN) in the Landes de Gascogne Regional Nature Park.
Additonal species identified in the field by members of UMR BIOGECO using a 
quadrat protocol (2023) were added.
Species names of hybrid taxa (those containing the character " x ") were 
excluded.

#    matK_BOLD_Arcachon
Plant species in the field were identified by members of UMR BIOGECO using a 
quadrat protocol (2023). In case of incomplete species identification 
(e.g., Rubus sp.), all plant species present in the region were considered 
for the considered genus . This included both "valid" and "invalid" species 
names recorded by the French National Natural Heritage Inventory (INPN) in 
the Landes de Gascogne Regional Nature Park (PNR des Landes de Gascogne). 
Species names of hybrid taxa (those containing the character " x ") were 
excluded.
