Next-generation SNPs from lignin biosynthesis gene and transcription factors reveal a hidden teak (Tectona grandis L. f.) lineage: implications for plantation resilience and forest management.

Next-generation SNP analysis uncovers a hidden third genetic lineage in Indian teak, revealing significant diversity and a potential introduced population from Myanmar.

• Why it matters: Understanding the full genetic diversity of teak is crucial for sustainable breeding, conservation, and forest management, especially with previously unrecognized lineages.
• What they did: Using 98 SNPs from lignin biosynthesis genes and transcription factors, the study analyzed teak populations across India, identifying three gene pools and revealing new population structure insights.
• The result: The discovery of a third, possibly introduced, lineage with high inbreeding and genetic isolation highlights the importance of documenting native and introduced gene pools to improve genetic conservation and plantation resilience.
