White oak (Quercus fabri Hance) regenerated stump sprouts show few senescence symptoms during 40 years of growth in a natural forest

Abstract Background The relationship between physiological age of parental trees and lifespan clonal offspring is unclear. White oak ( Quercus fabri Hance) has a high sprouting capability after harvest, with the regenerated sprouts being typical individuals. To determine whether undergo rapid senescence compared parent, levels 5-, 10-, 20- 40-year-old stump in natural forest were evaluated. antioxidative abilities transcriptomes these leaves shoots compared. Results Older still had robust systems, having lower peroxidation product but similar enzyme activity 5-year-old sprouts. greater transcriptional activities pathways related to cell growth division than younger leaves. However, older some unhealthy characteristics, such as increased base excision repair upregulated phagosome, proteasome glycerophospholipid metabolism leaves, which indicates that DNA damage tissue remodeling occurred more frequently Additionally, plant-pathogen interactions MAPK signals shoots, suffered from pathogen-related biotic stress. Conclusions same vitality level sprouts, although former characteristics. We conclude during their first 40 years growth, do not begin senesce, does significantly affect its offspring.
