Other claims from this paper (10)
- Intervention effect Phosphate deficiency initially reduced leaf area and root biomass in tree peony seedlings.
- Intervention effect Phosphate deficiency later significantly increased total and lateral root lengths in tree peony seedlings.
- Intervention effect Phosphate deficiency later elevated leaf anthocyanin content in tree peony seedlings.
- Observation Five key candidate genes, PoSPX1, PoPHT1;7, PoPAP8, PoPAP22 and PoGlpT, were identified in tree peony and their expression patterns validated.
- Observation Among the candidate genes, PoSPX1 showed the highest overall responsiveness.
- Observation PoGlpT, an organic phosphorus transporter, was highly responsive to Pi starvation in tree peony.
- Intervention effect Overexpression of PoSPX1 in Arabidopsis promoted root and shoot growth under low-Pi conditions.
- Intervention effect Overexpression of PoSPX1 in Arabidopsis stimulated anthocyanin accumulation under low-Pi conditions.
- Mechanism PoSPX1 promotes root elongation and anthocyanin accumulation in tree peony under phosphate deficiency.
- Mechanism The authors suggest these results indicate adaptive mechanisms to phosphate deficiency in tree peony, with PoSPX1 possibly playing an important regulatory role.
