Altered collective mitochondrial dynamics in the Arabidopsis msh1 mutant compromising organelle DNA maintenance
Chustecki, Joanna M.; Etherington, Ross D; Gibbs, Daniel J.; Johnston, Iain George (Journal article; Peer reviewed, 2022)Mitochondria form highly dynamic populations in the cells of plants (and almost all eukaryotes). The characteristics and benefits of this collective behaviour, and how it is influenced by nuclear features, remain to be ... -
Collective mitochondrial dynamics resolve conflicting cellular tensions: From plants to general principles
Johnston, Iain George; Chustecki, Joanna M. (Journal article; Peer reviewed, 2023)Mitochondria play diverse and essential roles in eukaryotic cells, and plants are no exception. Plant mitochondria have several differences from their metazoan and fungal cousins: they often exist in a fragmented state, ... -
Evolutionary inference across eukaryotes identifies universal features shaping organelle gene retention
Giannakis, Konstantinos; Arrowsmith, Samuel J.; Richards, Luke; Gasparini, Sara; Chustecki, Joanna M.; Røyrvik, Ellen Christine; Johnston, Iain (Journal article; Peer reviewed, 2022)Mitochondria and plastids power complex life. Why some genes and not others are retained in their organelle DNA (oDNA) genomes remains a debated question. Here, we attempt to identify the properties of genes and associated ... -
Exchange on dynamic encounter networks allows plant mitochondria to collect complete sets of mitochondrial DNA products despite their incomplete genomes
Giannakis, Konstantinos; Chustecki, Joanna M.; Johnston, Iain George (Journal article; Peer reviewed, 2022)Mitochondria in plant cells usually contain less than a full copy of the mitochondrial DNA (mtDNA) genome. Here, we asked whether mitochondrial dynamics may allow individual mitochondria to ‘collect’ a full set of mtDNA-encoded ... -
Network analysis of Arabidopsis mitochondrial dynamics reveals a resolved tradeoff between physical distribution and social connectivity
Chustecki, Joanna M.; Gibbs, Daniel J.; Bassel, George W.; Johnston, Iain George (Journal article; Peer reviewed, 2021)Mitochondria in plant cells exist largely as individual organelles which move, colocalize, and interact, but the cellular priorities addressed by these dynamics remain incompletely understood. Here, we elucidate these ...
