Assessing Genetic Variation in <i>Guadua angustifolia</i> Through RAD-Seq Analysis.

ABSTRACT: Guadua angustifolia, a native bamboo species of ecological and economic importance, has been widely studied in Colombia. This study focused on evaluating the genetic diversity and population structure of G. angustifolia from six natural populations in the Department of Nariño, Colombia, using restriction site-associated DNA sequencing (RADseq). A total of 224,996 high-quality SNPs were identified across 48 individuals. Observed heterozygosity (Ho) ranged from 0.398 in Consacá to 0.78 in Tumaco, while expected heterozygosity (He) was lower in all cases, ranging from 0.291 to 0.597. All populations exhibited negative inbreeding coefficients (FIS), from -0.316 to -0.763, indicating an excess of heterozygotes and suggesting predominantly outcrossing reproduction. Analysis of mole
