Breaking the Myth of Nuclear Power Omnipotence in the Cold War era: Discourse on Nuclear Power and the Movement against the Construction of Nuclear Power Plants in South Korea in the 1980s and early 1990s [PDF]

open access: yesInternational Journal of Korean History, 2023
In South Korea, the frontline of the Cold War in East Asia, an active anti-nuclear movement could not emerge until the 1970s due to the effects of Korean War, national division, and the Cold War culture.

Osmotic and Salt Stresses Modulate Spontaneous and Glutamate-Induced Action Potentials and Distinguish between Growth and Circumnutation in Helianthus annuus Seedlings

open access: yesFrontiers in Plant Science, 2017
Action potentials (APs), i.e., long-distance electrical signals, and circumnutations (CN), i.e., endogenous plant organ movements, are shaped by ion fluxes and content in excitable and motor tissues.

Plasmodesmata-Dependent Intercellular Movement of Bacterial Effectors

open access: yesFrontiers in Plant Science, 2021
Pathogenic microorganisms deliver protein effectors into host cells to suppress host immune responses. Recent findings reveal that phytopathogens manipulate the function of plant cell-to-cell communication channels known as plasmodesmata (PD) to promote ...

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]

open access: yes, 2020
In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

Medicago LINC complexes function in nuclear morphology, nuclear movement, and root nodule symbiosis 1[OPEN] [PDF]

open access: yes, 2018
Nuclear movement is involved in cellular and developmental processes across eukaryotic life, often driven by Linker of Nucleoskeleton and Cytoskeleton (LINC) complexes, which bridge the nuclear envelope (NE) via the interaction of Klarsicht/ ANC-1/Syne-1

Studying in vivo dynamics of xylem-transported 11CO2 using positron emission tomography [PDF]

open access: yes, 2020
Respired CO2 in woody tissues can build up in the xylem and dissolve in the sap solution to be transported through the plant. From the sap, a fraction of the CO2 can either be radially diffuse to the atmosphere or be assimilated in chloroplasts present ...

Aquaporins and Plant Leaf Movements [PDF]

open access: yesAnnals of Botany, 2007
Plant leaf movements can be mediated by specialized motor organs, the pulvini, or can be epinastic (i.e. based on different growth velocities of the adaxial and abaxial halves of the leaf). Both processes are associated with diurnally regulated increases in rates of membrane water transport, which in many cases has been shown to be facilitated by ...

Creating Contacts Between Replication and Movement at Plasmodesmata – A Role for Membrane Contact Sites in Plant Virus Infections?

open access: yesFrontiers in Plant Science, 2020
To infect their hosts and cause disease, plant viruses must replicate within cells and move throughout the plant both locally and systemically. RNA virus replication occurs on the surface of various cellular membranes, whose shape and composition become ...

RNA silencing movement in plants [PDF]

open access: yesJournal of Integrative Plant Biology, 2015
AbstractMulticellular organisms, like higher plants, need to coordinate their growth and development and to cope with environmental cues. To achieve this, various signal molecules are transported between neighboring cells and distant organs to control the fate of the recipient cells and organs.
