Genomic relations among 31 species of Mammillaria haworth (Cactaceae) using random amplified polymorphic DNA.
Thirty-one species of Mammillaria were selected to study the molecular phylogeny using random amplified polymorphic DNA (RAPD) markers. High amount of mucilage (gelling polysaccharides) present in Mammillaria was a major obstacle in isolating good quality genomic DNA. The CTAB (cetyl trimethyl ammonium bromide) method was modified to obtain good quality genomic DNA. Twenty-two random decamer pr...
متن کاملDevelopmentally specific soluble and membrane proteins and glycoproteins in Mammillaria gracillis Pfeiff. (Cactaceae) tissue culture
Artificial environmental conditions in the tissue culture influence growth and induce aberration from the characteristic organization pattern. As CAM plants, cacti are particularly susceptible to altered growth environment. In vitro propagated Mammillaria plants spontaneously produce callus which regenerates normal and hyperhydric shoots without the addition of any growth regulator. In order to...
متن کاملChromosome analysis of Mammillaria supertexta, M. crucigera and M. haageana and their comparison with M. san-angelensis (Cactaceae)
This is the first report of chromosome number in Mammillaria supertexta, M. crucigera and M. haageana, which was the same in the three species: 2n=22, x=11. This number coincides with the number reported for the genus Mammilaria and for the Cactaceae family. However, interspecific variation was observed in the karyotypes: M. supertexta exhibited longer chromosomes (1.79-3.21 μm) and those of M....

متن کاملMass Spectrometric Detection of New Betalains in Mammillaria Flowers
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...
