We studied plants with reduced expression of CYTC-1, one of two genes encoding the respiratory chain component cytochrome c (CYTc) in Arabidopsis, to understand how mitochondria communicate their status to coordinate metabolism and growth.

Dec 16, 2024 · In this work, we report that plants with reduced levels of the mitochondrial respiratory chain component cytochrome c (CYTc), required for electron transport coupled to oxidative phosphorylation and ATP production, show impaired growth and increased global expression of stress-responsive genes, similar to those observed after inhibiting the ...

Jul 1, 2012 · In this study, we analyzed the role of CYTc in plants through the analysis of Arabidopsis insertional mutants in CYTC-1 and CYTC-2. Knock-out of both genes is lethal to plants and produces an arrest of embryo development, showing …

Jan 8, 2024 · We studied plants with reduced expression of CYTC-1, one of two genes encoding the respiratory chain component cytochrome c (CYTc) in Arabidopsis, to understand how mitochondria communicate their status to coordinate metabolism and growth.

Histochemical staining of plants indicated that the Cytc-1 promoter directs preferential expression in root and shoot meristems and in anthers. In turn, plants transformed with the Cytc-2 promoter fusions showed preferential expression in vascular tissues of cotyledons, leaves, roots, and hypocotyls, and also in anthers.

We studied the effect of reducing the levels of the mitochondrial electron carrier cytochrome c (CYTc) in Arabidopsis thaliana. Plants with CYTc deficiency have delayed growth and development, and reach flowering several days later than the wild-type but with the same number of …

By using cytc mutant plants, we also tested whether reduced levels of CYTc could induce alterations in COP in vivo activity and whether this leads to a respiratory bypass via AOP for the benefit of primary metabolism and growth depending on the photoperiod conditions.

May 30, 2022 · Using Arabidopsis thaliana lines with changes in the levels of the respiratory chain component cytochrome c (CYTc), we investigated the role of this protein in germination and its relationship with hormonal pathways.

Feb 10, 2021 · Besides, this update also focuses on plant PCD and its relation with mitochondrial cytochrome-c (Cytc) release to cytosol. Changes in the dynamics and morphology of mitochondria were shown during the onset of cell death.

In Arabidopsis, CYTc is encoded by two genes, designated CYTC-1 and CYTC-2. Knock-out of CYTC-1 and CYTC-2 causes embryo developmental arrest indicating that CYT c is essential for plant development.
