Comprehensive mapping of molecular cytogenetic markers in pitaya (Hylocereus undatus) and related species.

ABSTRACT: Pitaya (Hylocereus undatus; 2n=22) is an important fruit crop from the Cactaceae family, originally domesticated in Mexico and the USA, and is now widely cultivated for its nutritional benefits. It is characterized by its distinctive triangular-shaped stems and large, showy flowers, thriving in arid and semi-arid environments, particularly in hot, dry climates. However, systematic chromosomal studies, including chromosomal mapping of cytogenetic markers in pitaya, are limited, presenting challenges for its cytogenetic improvement. To address this issue, we designed oligo-barcodes specific to thirty-three chromosome regions based on the pitaya reference genome and applied them to both pitaya and cactus (Selenicerus grandifloras; 2n=22) for oligo-barcodes mapping, karyot
