Author Correction: Revealing the complex genetic structure of cultivated amaryllis (Hippeastrum hybridum) using transcriptome-derived microsatellite markers

An amendment to this paper has been published and can be accessed via a link at the top of the paper.

The Article reports cultivars 'Chico' and 'Jewel' as double petal. It was brought to the authors' attention that this information may be incorrect. To confirm the correct assignment, the authors replanted the cultivars used in the study and recorded their phenotypic characteristics again, including flower colour and petal type. These results confirmed that 'Chico' is a single petal, 'Jewel' is a semi-double petal, and 'Blushing Bride' is a single petal cultivar. Therefore, in the Results subsection 'The genetic relationships and population structure of cultivated amaryllis' , "It is also noteworthy that the accessions within each cluster can also be described on the basis of their petal number (single or double) and colour, including 'Chico' and 'Ballerina' (both with double pink or red flowers) along with 'Papillo' , 'La Paz' , 'Exotic star' , 'Santiago' , 'Fairy tale' , and 'Faro' (single petals) in cluster I".

Exceptions include the 'Lemon sorbet' , 'Ballerina' and 'Chico' varieties. Of these varieties, the former possesses green single petals, whereas 'Ballerina' (red flowers) and 'Chico' (pink flowers) both have double petals. These exceptions are important because they illustrate the comprehensive nature of amaryllis population structure. " should read: "However, the N-J tree and structural plot generated in this study (Fig. 4) demonstrate that the 104 accessions we considered cannot be fully clustered according to the number of flowers or their colour, which illustrate the comprehensive nature of amaryllis population structure. " Finally, the corrected section of Supplementary Table 5, listing the characteristics of the affected cultivars, is included below as Table 1.
There are also several typographical errors in some of the names. Cultivar ' Amorize' should be ' Amorice' , and H. solandrifoliu should be H. solandrifolium.
These changes do not affect the overall conclusions of the Article.
