    In spite of the use of chromosome number, floral anatomy, pollen morphology, and serology, substantial disagreement remains regarding the systematics of the berberidaceae. To test competing hypotheses about intergeneric relationships in the family, sequences of the chloroplast encoded rbcL gene and ITS regions of the nuclear ribosomal repeat. This result is consistent with those studies results of geobiology, pollen morphology, molecular biology [13–16], and cytology [23, 29] of this genus, also supported by the deduction about the phylogeny of Berberidaceae by Wu et by: 2.

    An attempt is made in the present review to bring together a range of morphological data (vegetative and floral anatomy, palynology and embryology) on the Ranales (sensu lato), with particular reference to research work published after the publication of Eames's () book, and to discuss the relationships of the by: : Pollen morphology of Ericaceae and its systematic significance: Pollen morphology of Ericaceae (): A.K.M.

Pollen Morphology and the Relationship of the Plumbaginaceae, Polygonaceae, and Primulaceae to the Order Centrospermae Joan W. Nowicke and John 3. Skvarla Introduction The Centrospermae (Caryophyllales) represents one of the most controversial orders in the angio- sperms.

This group of at least 10 families, which in.) have examined pollen morphology of several Mahonia species to discuss relationships in Berberidaceae. However, no scanning electron micrographs of seeds have been reported in Mahonia. We finished a scanning electron microscope survey of pollen and seed features in M.

jingxiensis. Mahonia jingxiensis has the pollen. In spite of extensive studies using chromosome number, floral anatomy, pollen morphology, and serology, substantial disagreement still remains in the systematics of the Berberidaceae. We employed two different molecular systematic approaches, gene sequencing and restriction site analysis, to test competing hypotheses about intergeneric relationships in the by: POLLEN MORPHOLOGY OF SELECTED BEE FORAGE PLANTS Shubharani, R., Roopa, P.

& Sivaram, V. Laboratory of Biodiversity and Apiculture, Department of Botany, Bangalore University, Bangalore, India ABSTRACT Pollen taxonomy is the prerequisite to compare the pollen present in honey samples with special reference to.

Pollen morphology of 12 species representing 2 genera of the family Berberidaceae from Pakistan has been examined by light and scanning electron microscope. Pollen grains usually radially symmetrical, isopolar or apolar, spheroidal or perturate rarely colpate (3-more), sexine thicker than nexine.

No reports of Berberidaceae pollen have been found in published pollen analyses and the fragility of Berberis and Mahonia pollen grains may be a contributing factor. To prepare slides with intact pollen grains of these two genera the anther contents were sieved very gently prior to acetolysis for the reduced time of 3 min with little or no agitation at any stage.

The pollen morphology is not particularly specialized, but the uniformly punctate tectum and a massive endexine distinguish this species from all other taxa in the Berberidaceae s.L Thus the pollen lends support to those who favor separation of this genus on other characteristics. The phylogenetic relationship of Achlys to the Epimedium / Vancouveria or the Podophyllum groups was not resolved in the strict consensus tree (Fig.

2A). Bongardia was nested within the x =6 group and sister to Epimedium / Vancouveria in the parsimony tree, but it was allied with Achlys in the NJ tree (Fig.

Tracing the evolution of one of the most ancient major branches of flowering plants, this is a wide-ranging survey of state-of-the-art research on the early clades of the monocot phylogenetic tree.

It explores a series of broad but linked themes, providing for the first time a detailed and coherent view.
