Cadmium and arsenic-induced-stress differentially modulates Arabidopsis root architecture, peroxisome distribution, enzymatic activities and their nitric oxide content [PDF]

, 2020
In plant cells, cadmium (Cd) and arsenic (As) exert toxicity mainly by inducing oxidative stress through an imbalance between the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS), and their detoxification. Nitric oxide (NO)

Sensing and signaling for peroxisome autophagic degradation (pexophagy) in yeasts [PDF]

The Ukrainian Biochemical Journal, 2013

The autophagic degradation of cytosolic pools of peroxisomal proteins by a new selective pathway. [PDF]

, 2019
Damaged or redundant peroxisomes and their luminal cargoes are removed by pexophagy, a selective autophagy pathway. In yeasts, pexophagy depends mostly on the pexophagy receptors, such as Atg30 for Pichia pastoris and Atg36 for Saccharomyces cerevisiae ...

Peroxin 14 tags peroxisomes and interacts with Nbr1 for pexophagy in the filamentous insect pathogenic fungus Beauveria bassiana

Autophagy Reports, 2023
Pexophagy is a main pathway for selective degradation of peroxisomes. However, the molecular mechanisms underlying pexophagy remain fragmented in the filamentous fungi.

Regulation of Peroxisome Homeostasis by Post-Translational Modification in the Methylotrophic Yeast Komagataella phaffii

Frontiers in Cell and Developmental Biology, 2022
The methylotrophic yeast Komagataella phaffii (synoym Pichia pastoris) can grow on methanol with an associated proliferation of peroxisomes, which are subsequently degraded by pexophagy upon depletion of methanol.

The proppin Bcas3 and its interactor KinkyA localize to the early phagophore and regulate autophagy [PDF]

, 2021
To resolve the signaling mechanisms that mediate the starvation-induced processes of Dictyostelium sporulation and encystation, we performed insertional mutagenesis on cells harboring an mRFP-tagged spore gene.

Pexophagy in yeasts

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2016
Pexophagy, selective degradation of peroxisomes via autophagy, is the main system for reducing organelle abundance. Elucidation of the molecular machinery of pexophagy has been pioneered in studies of the budding yeast Saccharomyces cerevisiae and the methylotrophic yeasts Pichia pastoris and Hansenula polymorpha.

ACBD5 deficiency causes a defect in peroxisomal very long-chain fatty acid metabolism [PDF]

, 2016
Background Acyl-CoA binding domain containing protein 5 (ACBD5) is a peroxisomal membrane protein with a cytosolic acyl-CoA binding domain. Because of its acyl-CoA binding domain, ACBD5 has been assumed to function as an intracellular carrier of acyl ...

AeiA, an Atg8-interacting protein in Aspergillus oryzae, promotes peroxisome degradation by pexophagy

Autophagy Reports, 2023
There are two types of autophagy, non-selective (bulk) autophagy, in which substrates are randomly incorporated into autophagosomes, and selective autophagy, in which substrates are specifically targeted.
