Structural Features and Biological Properties of Ellagitannins in Some Plant Families of the Order Myrtales

open access: yesInternational Journal of Molecular Sciences, 2010
Plant tannins, including hydrolysable and condensed varieties, are well known antioxidants in medicinal plants, foods, and edible fruits. Their diverse biological properties and potential for disease prevention have been demonstrated by various in vitro ...

Aluminium Accumulation in Leaves of 127 Species in Melastomataceae, with Comments on the Order Myrtales [PDF]

open access: yesAnnals of Botany, 2002
The distribution and systematic significance of aluminium accumulation is surveyed based on semi-quantitative tests of 166 species, representing all tribes and subfamilies of the Melastomataceae as well as a few members of related families within the Myrtales.

The embryology and relationships ofPenaeaceae (Myrtales)

Plant Systematics and Evolution, 1984
Two species ofPenaeaceae (Penaea mucronata andSaltera sarcocolla), a unique South African family ofMyrtales, were investigated embryologically.Penaeaceae clearly agrees with otherMyrtales in its basic embryological characteristics, and further is characterized by its highly specialized features: ephemeral endothecium, 16-nucleatePenaea-type embryo sac,

Ultrastructure of Sieve-Element Plastids of Myrtales and Allied Groups

open access: yesAnnals of the Missouri Botanical Garden, 1984
The core families of Myrtales (69 species investigated) contain S-type sieve-element plastids. In these, the presence of several medium-sized spherular starch grains is probably a common trend in the order. Among those families usually closely associated or more or less distantly related, the great majority also have S-type plastids, some with the same

EMBRYOLOGY AND SYSTEMATIC POSITION OF HETEROPYXIS (MYRTALES)

American Journal of Botany, 1987
We present here the first study of the embryology of Heteropyxis , in order to evaluate its relationships with Myrtaceae, a family in which it has often been placed. On the basis of embryology, Heteropyxis is undoubtedly very closely allied to Myrtaceae,

The impact of receptacular growth on polyandry in the Myrtales

Botanical Journal of the Linnean Society, 1991
RONSE DECRAENE, L.-P. & SMETS, E., 1991. The impact of receptacular growth on polyandry in the Myrtales. The androecium of the Myrtales shows a wide variation in structure and development, linked with an original diplostemony. The difference between a centrifugal stamen inception in Lythraceae against a centripetal inception in other families has been ...

Reproductive Anatomy and Morphology of Myrtales in Relation to Systematics

open access: yesAnnals of the Missouri Botanical Garden, 1984
Evidence from reproductive morphology and anatomy (excluding palynology) favors an inclusive Myrtales of 11 core families (see below) over either a much broader Myrtales, as advocated, for example, by the Englerian school (most recently Melchior, 1964) or a narrower Myrtales and accompanying Lythrales, as advocated by Novak (1961, 1972) and more ...

Interfamilial Relationships in Myrtales: Molecular Phylogeny and Patterns of Morphological Evolution

Systematic Botany, 1997
Numerous phenotypic (morphological, palynological, cytological, and anatomical) studies have been conducted on Myrtales, yet the detailed relationships among the families of the order remain elusive. In this paper, the rbcL sequences of 50 taxa (39 representatives of Myrtales and 11 rosid outgroups) were analyzed using parsimony and maximum likelihood ...
