TL;DR: Some Mexican cacti of the genera Ariocarpus, Mammillaria, Obregonia, Pelecyphora, Solisia and Turbinicarpus have been studied with respect to their alkaloids and ethnobotany and N,N-Dimethyl-4-hydroxy-3-methoxyphenethylamine was found to occur in Ariocaruides.
Abstract: Some Mexican cacti of the genera Ariocarpus, Mammillaria, Obregonia, Pelecyphora, Solisia and Turbinicarpus have been studied with respect to their alkaloids and ethnobotany. Seven previously known cactus alkaloids were identified. N,N-Dimethyl-4-hydroxy-3-methoxyphenethylamine was found to occur in Ariocarpus agavoides. In Pelecyphora aselliformis N,N-dimethyl-3-hydroxy-4, 5-dimethoxyphenethylamine was identified as the major alkaloid. The possible relationship between the vernacular names of these plants and their alkaloid content is discusse.

TL;DR: Analysis of the reproductive ecology of Ariocarpus fissuratus at Cuatrociénegas region, Mexico suggests that the need for pollinators, presence of exotic pollinator, partial self-incompatibility and florivory negatively affect sexual reproduction and thus the persistence of this endangered species.
Abstract: The genus Ariocarpus comprises seven endangered species endemic to the Chihuahuan Desert. We studied the reproductive ecology of Ariocarpus fissuratus at Cuatrocienegas region, Mexico, in order to explore if reproductive traits influence population viability. The size of perianth, pistils and stamens, floral behavior and controlled pollination treatments were assessed to determine Cruden's outcrossing index (OCI), the outcrossing rate and the mating system. The breeding system was estimated with pollen/ovule ratios (P/O) and outcrossing rate was estimated by comparing progeny from self- and outcross-pollination treatments. Frequency and behavior of floral visitors was determined, and nectar production recorded. Ariocarpus fissuratus blooms synchronously during three weeks in autumn. Flowers display herkogamy and homogamy, and OCI and P/O ratio suggest xenogamy. Generalized linear mixed models were fitted to evaluate the effect of pollination treatment on fruit set and number of viable seeds yield...

TL;DR: The amount of genetic variation found indicates that the transferred SSR markers might be useful in large-scale population studies within the genus Cereus, indicating each population as a cohesive genetic cluster.
Abstract: The study of transferability of simple sequence repeats (SSR) among closely related species is a well-known strategy in population genetics, however transferability among distinct genera is less common. We tested cross-genera SSR amplification in the family Cactaceae using a total of 20 heterologous primers previously developed for the genera Ariocarpus, Echinocactus, Polaskia and Pilosocereus, in four taxa of the genus Cereus: C. fernambucensis subsp. fernambucensis, C. fernambucensis subsp. sericifer, C. jamacaru and C. insularis. Nine microsatellite loci were amplified in Cereus resulting in 35.2% of success in transferability, which is higher than the average rate of 10% reported in the literature for cross-genera transferability in eudicots. The genetic variation in the transferred markers was sufficient to perform standard clustering analysis, indicating each population as a cohesive genetic cluster. Overall, the amount of genetic variation found indicates that the transferred SSR markers might be useful in large-scale population studies within the genus Cereus.
