Overview

Integrative analysis supports synonymy of Lasiodiplodia brasiliensis with L. theobromae, stabilizing taxonomy.

Key Points

  • This study aims to clarify the taxonomic status of Lasiodiplodia brasiliensis in relation to L. theobromae.
  • Conducted multilocus phylogenetic analyses using genetic markers (ITS, tef1-α, tub2, rpb2)
  • Performed genome-scale phylogenetic analysis with single-copy orthologous genes
  • Compared morphological traits between L. brasiliensis and L. theobromae
  • Multilocus analyses showed unresolved relationships with low bootstrap support for L. theobromae clade
  • Genome-scale analysis revealed a strong support for a single monophyletic clade of both species
  • Morphological traits like conidial dimensions overlapped significantly, complicating species differentiation
