Other claims from this paper (9)
- Observation Functional allantoinase genes AtALN and RpALN were isolated from Arabidopsis and black locust, respectively.
- Observation The black locust allantoinase gene RpALN was isolated.
- Observation The proteins encoded by AtALN and RpALN were predicted to contain a secretory signal peptide.
- Method / resource Yeast-mutant complementation confirmed allantoinase gene function.
- Intervention effect Allantoin as the sole nitrogen source upregulated Arabidopsis AtALN.
- Observation Black locust RpALN expression varied among cotyledons, axis, and hypocotyls during germination and seedling growth.
- Observation Black locust RpALN was not expressed in roots.
- Observation In mature black locust trunk, RpALN expression was high in bark and cambium but undetectable in sapwood and transition zone.
- Observation RpALN expression in black locust bark and cambium increased in spring and fall compared with summer.
