Dr. Ligas studies the assembly and function of complex I, an important enzyme in the energy production process, particularly in plants like Arabidopsis thaliana and European mistletoe. He explores how these plants differ from humans in building this enzyme, which helps reveal why certain energy deficiencies can lead to health problems in both types of organisms. Additionally, he investigates Leigh syndrome, a genetic disorder that affects brain function, examining how factors like breathing patterns can influence the severity of symptoms in patients.
Key findings
In Arabidopsis thaliana, researchers found that the assembly process of complex I differs from humans, potentially enhancing our understanding of energy production defects.
European mistletoe was shown to have at least five times lower levels of key proteins involved in energy production, indicating a reliance on alternative energy processes due to the loss of complex I.
In patients with the m.9185T>C variant related to Leigh syndrome, one patient improved when her breathing rate decreased, suggesting that controlled breathing might alleviate some symptoms of this serious disorder.

Ligas J, Pineau E, Bock R, Huynen MA, Meyer EH
Plain English Researchers studied how a key enzyme, called complex I, is built in the plant Arabidopsis thaliana. They found that the assembly process is different from that in humans and that plants follow an older method of assembling complex I. This matters because understanding these differences can shed light on why defects in complex I can cause significant health problems in both plants and animals.
Who this helps: This helps scientists and plant researchers understand mitochondrial functions better.

Plain English This study looked at Leigh syndrome, a serious brain disorder caused by genetic changes, specifically the m.9185T>C variant. Researchers examined three patients and found that their bodies were reacting to excessive breathing, or hyperventilation, which might worsen their condition. Notably, one patient improved when her breathing rate slowed, suggesting that under-breathing could actually help those with this genetic variant.
Who this helps: This information benefits patients with Leigh syndrome and their doctors.
Plain English This study looked at the European mistletoe, a type of plant that relies on other plants for nutrition, and found that it has lost important parts of its cellular machinery needed for energy production. Specifically, it lacks complex I, which means its ability to produce energy through respiration is severely limited. The mistletoe showed at least five times lower levels of key proteins compared to a non-parasitic plant, indicating that it depends less on traditional energy pathways and more on other processes for energy.
Who this helps: This research helps scientists understand how parasitic plants adapt and survive, potentially guiding future studies on plant evolution and ecology.
