Clonal Fidelity and Genetic Diversity of Micropropagated Hancornia speciosa Gomes (Apocynaceae) as Evaluated by Molecular Markers
Open accessAbstract
The plant tissue culture procedures for asexual multiplication of Hancornia speciosa represent an important process facilitating the preservation of selected genotypes of this threatened species and large-scale production of plantlets for population reinforcement or other utilization. However, there is no research regarding the somaclonal variation of this threatened species at molecular level. This study aimed to evaluate the role of the multiplication process in the genetic stability of H. speciosa plantlets and calluses using molecular markers. The tissue culture techniques for H. speciosa micropropagation used in this study did not influence the occurrence of somaclonal variation, which can be related to the genotypes of the donor plants and to the low concentrations of growth regulators used in tissue culture procedures adopted. The results observed here provide a reliable methodology for further studies involving micropropagation techniques with the goal of preserving selected or endangered genotypes of H. speciosa without genetic losses and producing seedlings of this species on a large scale. In addition, it was possible to verify that the donor plants used in this study showed a relatively low genetic variability.

Micropropagation is an effective biotechnology technique used in horticulture, forestry, and agriculture that allows rapid and large-scale reproduction of true-to-type, disease-free, and genetically superior varieties.
“Micropropagation is an effective biotechnology technique used in the horticulture, forestry, and agriculture sectors that allows for the rapid and largescale reproduction of traits that are true-to-type, disease-free, and genetically superior varieties [12,13].”
From Somaclonal Variation and Clonal Fidelity in Commercial Micropropagation: Challenges and Perspectives (2025) · cites this paper as [13]
The Introduction (p. 2) says micropropagation can rapidly multiply plants with desirable characteristics on a large scale under adequate phytosanitary conditions. The Conclusions report genetic fidelity for H. speciosa under the study's conditions. The paper does not establish that the resulting plants are disease-free or genetically superior, or document use across all three named sectors. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
