Complex biomineralization pattern in cactaceae
Journal of Plant Physiology, 2004The infrared spectroscopic investigation of biominerals isolated from different Cactaceae species belonging to the Opuntioideae subfamily shows the presence of a very complex mineral composition, including whewellite (monohydrated calcium oxalate), opal (SiO2) and calcite (CaCO3). This is the first report on the presence of a calcium carbonate in these

The relevance of classifying the Cactaceae family into different subfamilies helps to better understand the subdivision into clades that differ morphologically (see key below). On the other hand, the delimitation of some subfamilies has shown to been difficult (for example the paraphyly of the Pereskioideae K.Schum. and the ambiguous relationships of

Radicle of Echinocactus platyacanthus (Cactaceae)
Plant and Soil, 1994Radicle of mature Echinocactus platyacanthus embryo is approximately 320 µm long and represents less then 1/7 of the embryonal axis length. The radicle-hypocotyl boundary can be distinguished according to the striking difference in the size and shape of cells in protoderm and procambium, as well as discontinuity and different number of the cell files ...

Molecular systematics of the Cactaceae
Cladistics, 2011Bayesian, maximum-likelihood, and maximum-parsimony phylogenies, constructed using nucleotide sequences from the plastid gene region trnK-matK, are employed to investigate relationships within the Cactaceae. These phylogenies sample 666 plants representing 532 of the 1438 species recognized in the family.

The objective of our investigation was to search the epidermis of Cactoideae Eaton seedlings and to compare characteristics of epidermis in different parts of the plant (hypocotyl ??nd stem). We researched the 3-month old seedlings of ten cacti species. The epidermis characteristics of the stem and hypocotyl, such as number of epidermis cells per mm2 ,

Stemsucculents, branched or unbranched, columnar, globose or with thick flattened stems or internodes, usually with very small scale-like and awl-shaped, rarely foliaceous leaves; stems and internodes often with warts or ribs, bearing areoles in the axils of the often absent leaves. Areoles mostly covered with felty hairs and spines.
