Spatiotemporal dynamics of age-related genes and the regulatory network of LaAGL2-3 in Larix kaempferi (Lamb.) Carr. based on the latest genome annotation.

ABSTRACT:

Background

In plants, time information is recorded in strictly ordered sequences of development events, resulting in age-associated physiological and morphological differentiation, including clear spatial gradients from the base to the crown within a single tree. However, the molecular mechanisms driving such ontogeny-related differentiation remain largely unknown.

Results

Based on our newly generated Larix kaempferi (Lamb.) Carr. genome annotation, we identified 307 age-related genes, which were grouped into two expression clusters reflecting opposite temporal trends. Spatial expression analysis further revealed 13 differentially expressed genes along the vertical axis of the tree, suggesting their roles in regulating spatially distinct physiological traits.
