Other claims from this paper (8)
- Intervention effect Drought stress changed the expression of differentially expressed genes linked to photosynthesis-related pathways in poplar leaves.
- Intervention effect Drought stress impaired photosynthetic function and carbon assimilation in poplar, as indicated by the gene expression changes.
- Intervention effect Drought stress increased reactive oxygen species production in poplar leaves.
- Intervention effect Drought stress led to malondialdehyde accumulation in poplar leaves.
- Intervention effect Under drought stress, key genes in the thioredoxin-peroxiredoxin pathway and cyclic electron flow, such as PGR5-L1A, were downregulated in poplar.
- Association The ZX4 poplar showed higher drought tolerance than ZX3 and ZX5.
- Association The ZX4 poplar maintained stronger activity in cyclic electron flow and the thioredoxin-peroxiredoxin pathway than ZX3 and ZX5.
- Recommendation PGR5-L1A, 2-Cys Prx BAS1, PrxQ and TPX are proposed as promising candidates for enhancing drought resistance in poplars through genetic improvement.
