TL;DR: The findings substantiate previous hypotheses that lead ions can be sequestered in cell walls and point to the possibility that capacity for lead binding might increase in cell response to lead.

TL;DR: Pulse-chase experiments indicated that CW and its thickenings can function as the final sequestration compartments and showed that Pb deposited in CW is not as safe for plant cell as previously believed.

TL;DR: Analysis of this actin structure's formation and participation in cellular reorganization provides insight into how the mechanisms used in cell motility are modified to mediate motile processes within specialized cells.

TL;DR: The results confirm that the direction of cytoplasmic streaming within pollen tubes is determined by the polarity of AFs in the bundles, and this work used myosin II subfragment 1 (S1) decoration to determine this direction.

TL;DR: The correlation between the degradation of strongly Ca2+-binding pectins and the growing level of those ions in the extracellular regions of the transmitting tract in the pollinated pistil of P. hybrida suggests that this process may constitute a mechanism for creating an optimum calcium medium for in vivo-growing pollen tubes.
