Overview

Analysis reveals positive selection and stability patterns of rubisco in plant clades, suggesting thermal adaptation.

Key Points

  • Significant evidence of positive selection was found across four plant clades, influencing enzyme adaptation.
  • Convergent substitutions in rubisco were identified, changing side chain polarity and solvent interactions.
  • Higher stability in rubisco was associated with warmer environmental conditions, though phylogenetic correction weakened this link.
  • The study utilized codon evolutionary models and phylogenetic methods to explore rubisco's evolutionary dynamics.
