Overview

Transcriptomic analysis shows melatonin improves biomass and carbon fixation in Cyphomandra betacea seedlings under selenium stress, indicating a protective effect on photosynthesis.

Key Points

  • This research evaluates the impact of melatonin on photosynthesis and growth in Cyphomandra betacea under selenium stress.
  • Applied 0.1 mg L−1 Na2SeO3 treatment to seedlings
  • Utilized transcriptomic analysis to assess gene expression
  • Measured biomass and antioxidant enzyme activities
  • Assessed photosynthetic attributes and Se uptake
  • Melatonin application increased seedling biomass and antioxidant enzyme activities
  • Transcriptomic analysis revealed changes in gene expression related to photosynthesis and flavonoid biosynthesis
  • Carbon fixation pathways and electron transport rates improved with melatonin intervention
  • Melatonin enhanced Se uptake and expression of Se transporters
