CLASP promotes stable tethering of endoplasmic microtubules to the cell cortex to maintain cytoplasmic stability in Arabidopsis meristematic cells. [PDF]

PLoS ONE, 2018
Following cytokinesis in plants, Endoplasmic MTs (EMTs) assemble on the nuclear surface, forming a radial network that extends out to the cell cortex, where they attach and incorporate into the cortical microtubule (CMT) array.

A win-win scenario for photosynthesis and the plasma membrane H+ pump

Frontiers in Plant Science, 2022
In plants, cytosolic and extracellular pH homeostasis are crucial for various physiological processes, including the uptake of macronutrients and micronutrients, cell elongation, cell expansion, and enzyme activity. Proton (H+) gradients and the membrane

PRX102 Participates in Root Hairs Tip Growth of Rice

Rice, 2023
Root hairs are extensions of epidermal cells on the root tips that increase the root contract surface area with the soil. For polar tip growth, newly synthesized proteins and other materials must be incorporated into the tips of root hairs.

Functional distinction of hyphal compartments

Scientific Reports, 2017
Hyphae of higher fungi grow at their tips and are compartmentalized by porous septa that enable inter-compartmental cytoplasmic streaming. Woronin bodies discontinue cytoplasmic streaming by plugging the septal pores. Here, it was assessed whether apical

Switching from a Unicellular to Multicellular Organization in an Aspergillus niger Hypha

mBio, 2015
Pores in fungal septa enable cytoplasmic streaming between hyphae and their compartments. Consequently, the mycelium can be considered unicellular. However, we show here that Woronin bodies close ~50% of the three most apical septa of growing hyphae of ...

Multi-scale characean experimental system: from electrophysiology of membrane transporters to cell-to-cell connectivity, cytoplasmic streaming and auxin metabolism.

Frontiers in Plant Science, 2016
The morphology of characean algae could be mistaken for a higher plant: stem-like axes with leaf-like branchlets anchored in the soil by root-like rhizoids.

Cold stress triggers premature fruit abscission through ABA-dependent signal transduction in early developing apple.

PLoS ONE, 2021
Fruit abscission is a complex physiological process that is regulated by internal and environmental factors. During early development, apple fruit are exposed to extreme temperature fluctuations that are associated with premature fruit drop; however ...

Actin Turnover Required for Adhesion-Independent Bleb Migration

Fluids, 2022
Cell migration is critical for many vital processes, such as wound healing, as well as harmful processes, such as cancer metastasis. Experiments have highlighted the diversity in migration strategies employed by cells in physiologically relevant ...

Quantification of temperature dependence of forces involved in cytoplasmic streaming using optical tweezers

Journal of Physics Communications
Cytoplasmic streaming is a phenomenon observed in plants where the circulation of cellular components occurs around the central vacuole. It is crucial for the spatio-temporal distribution of organelles in plant cells and thus has an important role in ...

Head-neck domain of Arabidopsis myosin XI, MYA2, fused with GFP produces F-actin patterns that coincide with fast organelle streaming in different plant cells

BMC Plant Biology, 2008
Background The cytoskeletal mechanisms that underlie organelle transport in plants are intimately linked to acto-myosin function. This function is mediated by the attachment of myosin heads to F-actin and the binding of cargo to the tails.
