Aperture pattern ontogeny in angiosperms.
Pollen grains display a wide range of variation in aperture number and arrangement (pattern) in angiosperms. Apertures are well-defined areas of the pollen wall surface that permit pollen tubeExpand

Males outcompete hermaphrodites for seed siring success in controlled crosses in the polygamous Fraxinus excelsior (Oleaceae).
Polygamy (including trioecy and subdioecy), the co-occurrence of males, hermaphrodites, and females in natural populations, is a rare and poorly studied breeding system expressed in FraxinusExpand

Evolution of oil-producing trichomes in Sisyrinchium (Iridaceae): insights from the first comprehensive phylogenetic analysis of the genus.
BACKGROUND AND AIMS Sisyrinchium (Iridaceae: Iridoideae: Sisyrinchieae) is one of the largest, most widespread and most taxonomically complex genera in Iridaceae, with all species except one nativeExpand

Differential patterns of morphological and molecular hybridization between Fraxinus excelsior L. and Fraxinus angustifolia Vahl (Oleaceae) in eastern and western France
We examined large‐scale patterns of morphology, genetic structure and ecological correlates of Fraxinus excelsior and the closely related species Fraxinus angustifolia in France, in order toExpand

Correlated variation in microtubule distribution, callose deposition during male post-meiotic cytokinesis, and pollen aperture number across Nicotiana species (Solanaceae).
In most flowering plants, a single cytokinesis follows the two meiotic divisions during pollen-grain ontogeny. Aperture pattern (i.e., aperture number and distribution on pollen surface) ontogenyExpand

Maternal inheritance of chloroplasts in the horsetail Equisetum variegatum (Schleich.)
Abstract Reliable data concerning the transmission of chloroplasts in the Pteridophyta are needed both for phylogenies based on chloroplast DNA (cpDNA) sequences and in order to study the evolutionExpand

Combined analyses of microsatellite and RAPD markers demonstrate possible hybridisation between Fraxinus excelsior L. and Fraxinus angustifolia Vahl.
Controlled reciprocal crosses were made between the common ash (Fraxirlus excelsior L.) and the narrow-leaved ash (Fraxirzus angustijolia Vahl). An appreciable proportion of hybrids were found amongExpand

Maternal inheritance of a chloroplast microsatellite marker in controlled hybrids between Fraxinus excelsior and Fraxinus angustifolia
Restriction fragment length polymorphism, polymerase chain reaction–restriction fragment length polymorphism and simple sequence repeat (SSR or microsatellites) analyses were performed to detectExpand

New insights in the recognition of the European ash species Fraxinus excelsior L. and Fraxinus angustifolia Vahl as useful tools for forest management
Common ash (Fraxinus excelsior L.) and narrow-leaved ash (F. angustifolia Vahl) are the most common ash species in Western Europe. The former is considered to be a highly valuable timber tree andExpand

Formation and function of a new pollen aperture pattern in angiosperms: The proximal sulcus of Tillandsia leiboldiana (Bromeliaceae).
Pollen grains are generally surrounded by an extremely resistant wall interrupted in places by apertures that play a key role in reproduction; pollen tube growth is initiated at these sites. TheExpand
