Nutlet micromorphology of the genus Marrubium L. and allies and its systematic implication (Lamiaceae: tribe Marrubieae)
Nutlets of 20 taxa of the tribe Marrubieae were examined by scanning electron microscopy (SEM) and detailed descriptions of nutlet micromorphological features for all examined taxa are provided. The nutlets exhibited variation in size, shape, color and surface sculpturing. The nutlets shape of most species studied is ovate, but rounded, broad ovate, elliptic, lanceolate, triangular and oblong c...
متن کاملTrichome Micromorphology of Egyptian Ballota (lamiaceae) with Emphasis on Its Systematic Implication
Trichomes of 5 taxa of the genus Ballota were examined by using light and scanning electron microscopy. The indumentum shows considerable variability among different species, and therefore, affords valuable characters in delimitation of species. The characters of taxonomic interest were presence of glandular and non-glandular trichomes, number of cells (uni-, bi-, trior multi-cellular), presenc...
متن کاملPhylogenetic Implications of a Unique 5.8S nrDNA Insertion in Cyperaceae
The purpose of this study was to assess the phylogenetic utility of a large insertion (3 bp) in the 5.8S gene of nuclear ribosomal DNA (nrDNA) in Cyperaceae and selected Juncaceae. This was done by reconstructing the character evolution of the insertion on a phylogeny derived from rbcL sequences. Results suggest that the insertion was gained once at the base of Cyperaceae followed by multiple l...
متن کاملThe phylogenetic position of Carex section Phyllostachys and its implications for phylogeny and subgeneric circumscription in Carex (Cyperaceae).
Wide speculation surrounds the origin and phylogenetic relationships of the most highly reduced sections in the genus Carex. In order to gain a better understanding of phylogeny in Carex, the relationship of the reduced sect. Phyllostachys to 12 putatively related sections, representing all four subgenera (Primocarex, Indocarex, Carex, Vignea), was inferred from sequences of the ITS (internal t...
متن کاملAmino acids composition of Teucrium nutlet proteins and their systematic significance.
BACKGROUND AND AIMS Plant species are considered as a good source of dietary proteins, although the nutritional quality of proteins depends on their amino acid composition. In this work the protein content and amino acid composition of nutlets of 21 Teucrium taxa (Lamiaceae) from Spain were analysed and their nutritional quality was compared with the minimum values established by the Food and A...
