How and why does the areole meristem move in Echinocereus (Cactaceae)?

Abstract: The enclosed areole meristem and internal bud development are understood to be an adaptation to protect the meristem and the bud from low temperatures. The anatomical evidence supports the hypothesis that the enclosed bud represents one synapomorphy for Echinocereus and also supports the exclusion of Morangaya from Echinocereus.

“…[ ][ ] Therefore, analyzing and comparing the chemical composition of the non‐fibrous woods in which WBTs predominate are relevant. In Mexico, non‐fibrous woods are well represented in the genera of the Cacteae tribe [ ][ ] and in the genus Echinocereus , which is relevant because Echinocereus is a monophyletic genus and differs from the other genera of the Echinocereeae tribe that have fibrous wood …”

“…Exomorfología de las yemas y botones florales. El desarrollo temprano del meristemo floral es claramente interno al tallo y permanece latente hasta que se diferencia en una yema floral y errumpe la epidermis, como ya había sido mencionado por Ross (1982) y corroborado por Sánchez et al (2015). La exomorfología de las yemas documentada minuciosamente en este trabajo para E. stramineus y E. coccineus, coincide con la descripción de Sánchez et al (2015) para diferentes especies del género.…”

“…However, it is regarded as a short shoot covered with trichomes and that dynamically produces stems (long shoots), leaves, spines, and/or flowers (Mauseth, 2006). The enclosed areole meristem and internal bud development are understood to be an adaptation to protect the meristem and bud from low temperatures (Sánchez et al, 2015).…”

“…Recent taxonomic synthesis of the Cactaceae family revealed the diversity and dynamics of the areole meristem in Cactaceae (Hunt et al, 2006). Of the 1438 species in the Cactaceae family, about 85% have monomorphic areoles; trichomes, stems or branches, leaves, spines and/or flowers are produced on the areole surface (Hunt et al, 2006;Sánchez et al, 2015). The remaining 15% of the species, included in the subfamily Cactoideae, show certain modifications in the morphology and anatomy of their areoles, which are expressed in the placement of their organs (Sánchez et al, 2015).…”
