This subgroup contains the yellow-flowering species of the genus, which have high medicinal and ornamental value and a narrow geographical distribution. These species differ in their tolerance to high light intensity. This study aimed to explore the differences in their light-stress responses and light damage repair processes, and the effect of these networks on secondary metabolite synthesis. Two-year-old plants of both species grown at 300 µmol·m^-2·s^-1 photosynthetically active radiation (PAR) were shifted to 700 µmol·m^-2·s^-1 PAR for 5 days shifting back to 300 µmol·m^-2·s^-1 PFrontiers in plant science1071458https://www.ebi.ac.uk/biostudies/studies/S-EPMC9762238biostudies-literatureA comparative study on photosynthetic characteristics and flavonoid metabolism between <i>Camellia petelotii</i> (Merr.)
