It is vital to measure the levels of genetic diversity and differentiation between populations in a species to understand the current genetic structure and evolution of the species. Here, MIG-seq (multiplexed inter-simple sequence repeat genotyping by sequencing) was employed to assess the genetic variation in two tropical leguminous tree species, Dalbergia cochinchinensis and D. nigrescens, in Cambodia and Thailand.

- The study focuses on understanding the genetic basis and population structure of Taxodium distichum, a conifer found in North America's wetlands, specifically comparing two varieties: bald cypress and pond cypress.
- Using high-throughput DNA sequencing, researchers analyzed genetic variation among 96 individuals from different populations, revealing at least three distinct genetic groups with significant genetic differentiation despite their overlapping distribution.
- The findings indicate that bald cypress populations are genetically split by geography, suggesting a historical westward expansion and that pond cypress diverged from bald cypress in the late Miocene, influencing local adaptation and differentiation.
