“…Here, several antioxidative enzymes showed lowed activities in elder sprouts, but peroxidation products had not accumulated (Figure 1 and 2), that meant the 35-year age gap showed slightly in uence on antioxidative abilities both at the transcriptional and physiological levels, 40 years old regenerated sprouts still kept capacity to eliminate peroxidation products. This trend is different from senescent plant organs: antioxidative enzymes activities and ROS increased during Tulipa gesneriana petal senescence (Wang et al 2020); ROS increased but antioxidative enzymes activities decreased during rice leaf senescence (Zhou et al 2020).…”

Background: The linkage between parent tree’s physiological age and clonal offspring’s lifespan is unclear. White Oak (Quercus fabri Hance) have high sprouting ability after harvest, the regenerated sprouts are typical clonal individuals. Methods: To confirm whether regenerated sprouts will senesce faster, we evaluated the senescence level regenerated stump sprouts with the age of 5-, 10-, 20- and 40- years in the natural forest, compared antioxidative abilities and transcriptomes in leaves and shoots. Results: We found elder regenerated sprouts still had robust antioxidative system, peroxidation products were lower in elder sprouts, antioxidative enzymes activities were similar in 5- and 40-years sprouts. Elder leaves even had higher transcriptional activities in pathways related to cell growth and division. However, elder sprouts also had a few signals of unhealthy: base excision repair, proteasome, proteasome, and glycerophospholipid metabolism pathways upregulated in 40 years leaves, that meant DNA damage and tissue remodeling was more frequent in leaves; plant-pathogen interaction and MAPK signals pathways upregulated in elder shoots, that meant shoots suffered more biotic stress form pathogen. Conclusions: The results indicate 40 years sprouts still had the same vitality with 5 years sprouts, although some unhealthy signals occurred in 40 years sprouts. We conclude that regenerated stump sprouts do not begin to senesce in 40 years, parent tree’s physiological age do not significant shorten the lifespan of clonal offspring.

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