e0“This study aimed to analyze the genetic diversity, with the use of ISSR (inter-simple sequence repeat) markers, of natural populations of mariri (B. caapi ethnovariety Tucunacá) in the Southern Amazon”
e1“The analysis revealed 92.3% polymorphism, with an average of 11.55 amplified bands per primer and a mean PIC of 0.466, considered moderately informative”

Other claims from this paper (7)
- Association Natural populations of B. caapi had greater genetic diversity than cultivated ones.
- Observation AMOVA attributed 58% of genetic variation in B. caapi to differences between populations.
- Observation Gene flow among B. caapi populations is low (Nm = 0.485).
- Observation B. caapi populations show strong genetic structuring (Fst = 0.582).
- Observation The UPGMA dendrogram grouped B. caapi populations into two main clusters.
- Observation Bayesian analysis identified three genetic clusters of B. caapi, reflecting geographic isolation and human management.
- Observation Cultivated B. caapi populations at the Xingu Park Indigenous Territory maintained significant genetic diversity.
