...Wanying Zhao; Xiaolu Qu; Yuhui Zhuang; Ludi Wang; Maurice Bosch; Vernonica E. Franklin-Tong; Yongbiao Xue; Shanjin Huang ABSTRACT Self-incompatibility (SI) in the poppy Papaver rhoeas triggers dramatic alterations in actin within pollen tubes. However, how these actin alterations...

...Yoko Mizuta; Tetsuya Higashiyama; Jenny Russinova ABSTRACT Pollen tube guidance is a unique navigating system that is required for the successful sexual reproduction of plants. As plant sperm cells are non-motile and egg cells are embedded deep inside the female tissues, a pollen tube delivers...

... fusions have been observed except for gamete fusions. We recently reported that the fertilized central cell (the endosperm) absorbs the persistent synergid, a highly differentiated cell necessary for pollen tube attraction. The synergid–endosperm fusion (SE fusion) appears to eliminate the persistent...

... and is distributed throughout the entire pollen tube. In adf10 mutants, severing and monomer dissociation events for apical actin filaments are reduced, and the apical actin structure extends further toward the tube base than in wild-type tubes. In particular, the percentage of apical actin filaments that form large...

...Jae-Ung Hwang; Guang Wu; An Yan; Yong-Jik Lee; Claire S. Grierson; Zhenbiao Yang Rapid tip growth allows for efficient development of highly elongated cells (e.g. neuronal axons, fungal hyphae and pollen tubes) and requires an elaborate spatiotemporal regulation of the growing region. Here, we use...

...Richard M. Parton; Sabine Fischer-Parton; Anthony J. Trewavas; Masaaki K. Watahiki The growing pollen tube provides an excellent single cell model system in which to study the mechanisms determining growth regulation, polarity and periodic behaviour. Previously, using FM4-64, we identified periodic...

... at the growing pollen tube apex and address the question of their relationship to growth, we have used the membrane stain FM4-64 both as a structural marker and as a quantitative assay. Labelling of living Lilium Longiflorum pollen tubes by FM4-64 resulted in a distinct staining pattern in the tube apex, which...

..., mitosis, pollen tube, sperm (plant), Tradescantia. Introduction As the point of attachment for spindle fibers, the kinetochore plays a crucial role in the movement of chromosomes to the poles during mitosis and meiosis (see Rieder, 1982; Mitchison, 1988; Niklas, 1988a; Brinkley et al. 1989; Salmon, 1989...

...TADASHI KOHNO; TERUO SHIMMEN Using a Ca 2+ ionophore, A23187, the free Ca 2+ concentration ([Ca 2+ ]) in the cytoplasm of pollen tubes of Lilium longiflorum was controlled from the cell exterior. At [Ca 2+ ] higher than 1.0x10 −5 M (pCa5.0), cytoplasmic streaming was inhibited, and the inhibition...

...A. TIEZZI; A. MOSCATELLI; C. MILANESI; F. CIAMPOLINI; M. RESTI Nicotiana pollen tube extracts were treated with 20 μM-taxol and structures derived from the cytoskeleton were collected and observed in the electron microscope. We have identified three different groups of elements with characteristic...
