Other claims from this paper (10)
- Observation Initial indole-3-acetic acid levels in chestnut cuttings were lower, about 50% of those in poplar.
- Observation Chestnut cuttings had an unfavorable auxin-cytokinin balance for adventitious rooting.
- Observation Chestnut cuttings showed enrichment of sugars and phenolic acids.
- Observation Chestnut cuttings showed depletion of rooting-related amino acids and flavonoids.
- Observation Stage-specific regulation of genes for meristem activation, auxin transport and stress responses showed delayed or reduced expression in chestnut.
- Observation The gene CdABCG37 was upregulated at later stages in chestnut cuttings.
- Observation The genes CdPID and CdMYB12 were downregulated in chestnut cuttings.
- Observation American chestnut cuttings had higher levels of lignin and H2O2 than easy-to-root poplar.
- Observation Adult American chestnut trees have high recalcitrance to adventitious root formation when propagated as cuttings.
- Observation Time-course transcriptomics identified potential adventitious root development genes in American chestnut.
