The journey of cardosin A in young Arabidopsis seedlings leads to evidence of a Golgi-independent pathway to the protein storage vacuole

Frontiers in Plant Science, 2023
The aspartic proteinase cardosin A is a vacuolar enzyme found to accumulate in protein storage and lytic vacuoles in the flowers and protein bodies in the seeds of the native plant cardoon.

A New Independent Limit on the Cosmological Constant/Dark Energy from the Relativistic Bending of Light by Galaxies and Clusters of Galaxies

, 2008
We derive new limits on the value of the cosmological constant, $\Lambda$, based on the Einstein bending of light by systems where the lens is a distant galaxy or a cluster of galaxies.

In vivo imaging of the tonoplast intrinsic protein family in Arabidopsis roots [PDF]

, 2009
Background: Tonoplast intrinsic proteins (TIPs) are widely used as markers for vacuolar compartments in higher plants. Ten TIP isoforms are encoded by the Arabidopsis genome.

JA‐Mediated Regulation of Amino Acid Homeostasis Adjusts Metabolic Flux and Enhances Spider Mite Tolerance via the SlJAZ8‐SlWRKY57‐SlAVT6s Module in Tomato

Advanced Science, EarlyView.
This study elucidates a novel SlJAZ8‐SlWRKY57‐SlAVT6A/SlAVT6B module that effectively channels metabolic flux from primary to secondary metabolism, impacting plant growth, development, and resistance. Two novel vacuolar amino acid exporters, SlAVT6A and SlAVT6B, fine‐tunes trichomes, terpenes, and gibberellins, bolstering spider mite resistance.

New insights into the tonoplast architecture of plant vacuoles and vacuolar dynamics during osmotic stress

BMC Plant Biology, 2005
Background The vegetative plant vacuole occupies >90% of the volume in mature plant cells. Vacuoles play fundamental roles in adjusting cellular homeostasis and allowing cell growth.

Tripartite interactions comprising yeast-endobacteria systems in the gut of vector mosquitoes

Frontiers in Microbiology, 2023
It is shown that bacteria use yeast as a niche for survival in stressful conditions, therefore yeasts may act as temporary or permanent bacterial reservoirs.

Toxoplasma gondii F-actin forms an extensive filamentous network required for material exchange and parasite maturation [PDF]

, 2017
Apicomplexan actin is important during the parasite's life cycle. Its polymerization kinetics are unusual, permitting only short, unstable F-actin filaments.

3D Brain Vascular Niche Model Captures Glioblastoma Infiltration, Dormancy, and Gene Signatures

Advanced Science, EarlyView.
This study developed a 3D brain vascular niche model that capture the key features of glioblastoma including perivascular infiltration, gene signature, dormancy and chemo resistance, by comparing 3D model with in vivo condition using identical glioma stem cells.

Calcium release through P2X4 activates calmodulin to promote endolysosomal membrane fusion [PDF]

, 2015
Intra-endolysosomal Ca(2+) release is required for endolysosomal membrane fusion with intracellular organelles. However, the molecular mechanisms for intra-endolysosomal Ca(2+) release and the downstream Ca(2+) targets involved in the fusion remain ...

The SlDOF9‐SlSWEET17 Module: a Switch for Controlling Sugar Distribution Between Nematode Induced Galls and Roots in Tomato

Advanced Science, EarlyView.
Root‐knot nematode (RKN) disease seriously affects the yield and quality of vegetable crops. SlDOF9‐SlSWEET17 model helps plants resist RKN infection during early stage by switching off the sugar transport capacity of other SlSWEET proteins that are hijacked by RKNs.
