In 1908 Gustav Senn published a famous book on the photic movement of chloroplasts. He concluded that chloroplasts accumulate in the region where optimally irradiated. Here I provide a brief biography of Gustav Senn and review his achievements, including a diagram explaining the ten types of chloroplast arrangement he documented.

Explaining the “Pulse of Protoplasm”: The search for molecular mechanisms of protoplasmic streaming

Biologists returned to contraction as a means to explaining motion within the cell in the twentieth century. This preference was a result of the discovery of the pulse motion of protoplasm, the influence of work in muscular contraction, and the transition from colloid chemistry to research on macromolecules.

ROP GTPase-mediated auxin signaling regulates pavement cell interdigitation in Arabidopsis thaliana

Cell shape formation plays important roles during plant growth and development. Arabidopsis thaliana leaf and cotyledon pavement cells, displaying interdigitated jigsaw-puzzle appearance, provide an ideal model system for studying the mechanism of cell shape formation. Auxin coordinates two Rho GTPase proteins mediated pathways to coordinate the formation of indentations and lobes.

Plant villins: Versatile actin regulatory proteins

Villin is a versatile actin regulatory protein with actin-nucleating, capping, severing and bundling activity. It is increasingly considered as the major regulator of actin dynamics in plants. In this review article, we summarize our current understanding of plant villins’ functions and mechanisms of action.

The endoplasmic reticulum: A dynamic and well-connected organelle

In this review we discuss the organisation, dynamics and interactions of an important sub-cellular membrane bounded compartment the endoplasmic reticulum which is responsible for much of the cellular protein processing. We consider the control of its shape, movement, interactions with organelles such as the Golgi, plasma membrane and peroxisomes, plus its role as a surface for metabolic enzymes.

Organelle trafficking, the cytoskeleton, and pollen tube growth

Organelle movement is essential for the growing plant cells as it allows to deliver specific molecules towards particular cell sites; movement is mostly based on actin filaments and on actin-based motor proteins although microtubules and microtubule-based motor proteins also likely play a subtle but important role.

The pollen tube clear zone: Clues to the mechanism of polarized growth

Inside pollen tubes there is continuous lengthwise movement with specific structure. All organelles move tip-wards along the cell boundary, but starch grains and vacuole turn back before reaching the tip, adding to a reverse flow of mitochondria, internal membranes and vesicles back down the center, creating a “clear zone.”

Blue-light-induced rapid chloroplast de-anchoring in Vallisneria epidermal cells

Regulation of intracellular distribution of chloroplasts is important for plants to survive fluctuating environment. A centrifugation method revealed that “chloroplast de-anchoring” is an initial process of chloroplast avoidance induced by strong light in an aquatic angiosperm Vallisneria. The response seems to be mediated by blue-light receptor phototropins and cytoplasmic calcium.

Chloroplast movements in response to light are important for plant adaptation to light conditions. This work shows that in moss, the function of the kinesin-related protein, PpKAC, is important for actin but not microtubule-dependent light avoidance. It also shows that PpKAC may participate in this process by stabilizing actin filaments.

Clues to the signals for chloroplast photo-relocation from the lifetimes of accumulation and avoidance responses

Signal(s) transferred from photoreceptors (phototropins) to chloroplasts in chloroplast photorelocation movement is still unknown. The durations of chloroplast avoidance and following accumulation response after partial cell irradiation with strong blue light were quite different, suggesting that the signals and the signal lifetimes of the two responses are different each other.

Simplification of vacuole structure during plant cell death triggered by culture filtrates of Erwinia carotovora

In defense-related cell death, vacuole simplification has been considered as a prelude to the vacuole’s rupture. Hirakawa et al. discovered a new type of the cell death that vacuoles become simpler but maintain their integrity at the onset of cell death. The results call for rethinking the roles of vacuole simplification.
