The ability to regenerate and form an entire plant from individual tissues or organs, or even from a single somatic cell, is definitely the basis of micropropagation procedures and plant regeneration systems (Rocha et al., 2018). Owing to high multiplication rates more than quick periods and in reduced and sterile spaces, tissue cultures allow large-scale and rapid in vitro propagation and conservation of plant material (P ez-Molphe-Balch et al., 2015). Inside the Cactaceae family members, meticulously managed propagation approaches are vital for the prevention of overharvesting and also the promotion of sustainable production of endangered 5-HT3 Receptor Antagonist Storage & Stability species that happen to be prized within the ornamental horticultural trade. In vitro regeneration techniques offer an alternative to standard propagation, especially for slow-growing endangered species n (Lema-Rumiska and Kulus, 2014; Goettsch et al., 2015; P ez-Molphe-Balch et al., 2015). Melocactus glaucescens has a light green stem in addition to a white cephallium, which confer higher ornamental value. Below organic circumstances, M. glaucescens reproduces sexually and will not ramify or create lateral shoots unless the plant suffers some kind of injury (Machado, 2009). Unlawful harvesting and degradation of its natural habitat pose a severe threat to this species; thus, protocols for in vitro shoot organogenesis of M. glaucescens have been created to address the overharvesting of this species within the wild (Torres-Silva et al., 2018). In vitro propagation of M. glaucescens remains a challenge simply because organogenesis in plant development regulators (PGR)-free medium outcomes in low numbers of shoots per explant. However, organogeneses in media with PGR have already been shown to lead to higher proportions of shoots with morphological and/or physiological alterations (Torres-Silva et al., 2018). Despite the observation of a somaclonal variation in the 1st round of shoot organogenesis by Torres-Silva et al. (2018), there is certainly no correlation involving this somaclonal variation and also the observed morphological alterations; for that reason, additional studies are essential to strengthen the in vitro shoot production protocols of this species. Recent improvements to in vitro shoot production primarily based on intentional wounding within the axillary meristems have successfully elevated the number of shoots per explant (Torres-Silva et al., 2021). Availability of a transcriptome profile would expand the understanding in the molecular mechanisms involved in the development and physiology of this species and enable the usage of molecular tools to improve in vitro propagation. Transcriptome data provide an efficient approach to uncover genes or gene households encoding enzymes or transcription elements involved in many morphophysiological pathways (Xiao et al., 2013; Nadiya et al., 2018; Ebenezer et al., 2019), hence offering a beneficial resour
