    The effect of different external factors on pollen germination and pollen tube growth is well documented for several species. On the other hand the consequences of these factors on the division of the generative nucleus and the formation of callose plugs are less known. In this study we report...

    Betula pendula Roth clones were examined to study the relationship between pollen grain size and pollen tube growth rate and pollen and seed performance. Two hypotheses were tested: (i) pollen donors with larger pollen grains have faster growing pollen tubes and (ii) maternal plants produce more...

    Background and Aims Microsporogenesis leading to monosulcate pollen grains has already been described for a wide range of monocot species. However, a detailed study of additional callose deposition after the completion of the cleavage walls has been neglected so far. The study of additional...

    Profilin is an actin-binding protein involved in the dynamic turnover and restructuring of the actin cytoskeleton in all eukaryotic cells. We previously cloned a profilin gene, designated as LePro1 from tomato pollen. To understand its biological role, in the present study, we investigated the...

    Taxus yunnanensis Cheng et L. K. Fu is a rare species endemic to Southeast Asia. The development of the male reproductive structures with emphasis on microsporogenesis and microgametogenesis are described for the first time. Our results showed that T. yunnanensis exhibits several features that...
