In this review, we address the question of how the tip-growing pollen tube achieves its rapid
rate of elongation while maintaining an intact cell wall. Although turgor is essential for …

The cell wall (CW) is a thin and rigid layer encasing the membrane of all plant and fungal
cells. It ensures mechanical integrity by bearing mechanical stresses derived from large …

Morphogenesis of plant cells is tantamount to the shaping of the stiff cell wall that surrounds
them. To this end, these cells integrate two concomitant processes: 1), deposition of new …

Turgor generates the stress that leads to the expansion of plant cell walls during cellular
growth. This has been formalized by the Lockhart equation, which can be derived from the …

Cellular responses rely on signaling. In plant cells, cytosolic free calcium is a major second
messenger, and ion channels play a key role in mediating physiological responses. Self …

Pollen tube growth is central to the sexual reproduction of plants and is a longstanding
model for cellular tip growth. For rapid tip growth, cell wall deposition and hardening must …

The polar growth process characterizing pollen tube elongation has attracted numerous
modeling attempts over the past years. While initial models focused on recreating the correct …

Calcium is an abundant element with a wide variety of important roles within cells. Calcium
ions are inter-and intra-cellular messengers that are involved in numerous signalling …

Cellular growth in plant, fungal and bacterial cells is based on the mechanical deformation
of the cellular envelope by the hydrostatic turgor pressure. Shape generation is therefore a …

Person re-identification is an important technique towards automatic recognition of a person
across non-overlapping cameras. In this paper, a novel patch selection method based on …
