Taxon Proposed annotation Current Annotation Cactaceae spp. (#4) and Orchidaceae spp. (#8) in Appendix II, and all taxa annotated with #1 Designates all parts and derivatives, except: a) seeds, spores and pollen (including pollinia), except seeds of Mexican Cactaceae spp. originating in Mexico; b) seedling or tissue cultures obtained in vitro, in solid or liquid media, transported in sterile co...
Betacyanins are natural, red-violet betalain pigments which can be found in plenty of plants of the Cactaceae family. The Mammillaria is the widest genus of the Cactaceae family of which fruit was examined for betacyanins contents. As a result of the investigation, a new pigment structure, mammillarinin, was identified. Heretofore, no betacyanins of Mammillaria coronata flowers has been extensi...
Hypogeococcus pungens Granara de Willink, sensu stricto, is a serious pest of cacti in Puerto Rico threating many Caribbean islands. A classical biological control program for H. pungens was initiated for Puerto Rico in 2010 with a survey for natural enemies of H. pungens in its native range of Argentina. Biological differences were observed between populations of H. pungens sampled on Amaranth...
The Data Availability statement for this paper is incorrect. The correct statement is: All relevant data are available from Figshare. The complete dataset of chemical composition in Cactaceae wood is available under the DOI: http://dx.doi.org/10.6084/m9.figshare.1300164. The matrix for FTIR spectra is available under the DOI: http://dx.doi.org/10.6084/m9.figshare. 1300167. The report of S/G rat...
Copestylum alberlena, sp. nov. (Diptera: Syrphidae) was reared from larvae collected in decaying platyclades of Opuntia Mill. (Cactaceae) in the state of Veracruz (México). The thirdinstar larva, puparium, and adult morphology are described. Preliminary data about its life cycle and breeding behavior are included. This species is close to Copestylum tamaulipanum (Townsend), also breeding in Cac...
The cacti are well-known desert plants, widely recognized by their specialized growth form and essentially leafless condition. Pereskia, a group of 17 species with regular leaf development and function, is generally viewed as representing the "ancestral cactus," although its placement within Cactaceae has remained uncertain. Here we present a new hypothesis of phylogenetic relationships at the ...
The vascular cambium is a lateral meristem that produces secondary xylem (i.e., wood) and phloem. Different Cactaceae species develop different types of secondary xylem; however, little is known about the mechanisms underlying wood formation in the Cactaceae. The KNOTTED HOMEOBOX (KNOX) gene family encodes transcription factors that regulate plant development. The role of class I KNOX genes in ...
The ever-increasing occurrence of cancer and the severe side effects and limited efficacy of current cancer chemotherapy based on chemical drugs shift the attention toward drugs of plant origin. The Cactaceae family comprises more than 1500 species, but until recently only a few of them have been tested for their chemopreventive and anticancer attributes, leaving a wide unexplored area still wa...
BACKGROUND This study aimed to record the use, and knowledge that residents from São Francisco community (Paraiba, Brazil) have regarding the Cactaceae. METHODS Semi-structured interviews were carried out with 118 informants; 50 men and 68 women. The cacti cited in this study were organised into use categories and use values were calculated. Differences in the values applied to species and us...
Chromosome numbers are reported for 112 collections of Cactaceae, including 102 collections of Opuntia. Reports are presented for 33 species in five genera and a total of 36 taxa. Two specimens were sterile. Emphasis was given to the documentation of intraspecific ploidy-level consistencies and differences, because of the current poor state of knowledge about the populational integrity of chrom...
