Characterization of the polyphenolic composition of purple loosestrife (Lythrum salicaria).

Phenolic compounds of purple loosestrife (Lythrum salicaria L.) were analysed by the use of liquid chromatography-mass spectrometry (LC/MS) equipped with atmospheric pressure chemical ionisation (APCI) and electrospray ionisation (ESI). The presence of vitexin and orientin as well as their isomers, isovitexin and isoorientin, were confirmed using ion trap multiple stage LC/MS3 analysis. Several...

Regulation of pollen tube growth

Ions and Pollen Tube Growth

Ions play a crucial role in the control of pollen tube growth. In this review we focus on four that seem especially important: calcium (Ca2+), protons (H+), potassium (K+), and chloride (Cl–). Ca2+ in the extracellular medium is essential for growth; it forms a steep intracellular tip-focused gradient, and exhibits a prominent extracellular tip-directed Ca2+ influx. pH is also essential for gro...

Fast pollen tube growth in Conospermum species.

BACKGROUND AND AIMS An unusual form of pollen tube growth was observed for several Conospermum species (family Proteaceae). The rate of pollen tube growth, the number of tubes to emerge and the ultrastructure of these tubes are given here. METHODS Pollen was germinated in vitro in different sucrose concentrations and in the presence of calcium channel blockers, and tube emergence and growth w...
