Key Findings
- The study, conducted by researchers from the Universitat de Girona, focused on the differences in periderm formation between cork oak and holm oak
- Cork oak forms a persistent periderm, resulting in a uniform outer bark, while holm oak forms sequential periderms, creating a heterogeneous outer bark
- Genetic analysis revealed that cork oak's ability to produce thick, homogeneous cork is due to the upregulation of specific genes related to suberin production and cell wall biogenesis
