NTRC-dependent redox balance of 2-Cys peroxiredoxins is needed for optimal function of the photosynthetic apparatus
(National Academy of Sciences, 2017)
Thiol-dependent redox regulation allows the rapid adaptation of chloroplast function to unpredictable changes in light intensity. Traditionally, it has been considered that chloroplast redox regulation relies on ...

Proteomic pattern alterations of the cyanobacterium Synechocystis sp. PCC 6803 in response to cadmium, nickel and cobalt
(Elsevier, 2014)
Cyanobacteria represent the largest and most diverse group of prokaryotes capable of performing oxygenic photosynthesis and are frequently found in environments contaminated with heavy metals. Several studies have been ...

Chloroplast redox homeostasis is essential for lateral root formation in Arabidopsis
(Taylor & Francis, 2012)
Redox regulation based on dithiol-disulphide interchange is an essential component of the control of chloroplast metabolism. In contrast to heterotrophic organisms, and non-photosynthetic plant tissues, chloroplast redox ...

Autophagy is activated and involved in cell death with participation of cathepsins during stress-induced microspore embryogenesis in barley
(Company of Biologists, 2018)
Microspores are reprogrammed towards embryogenesis by stress. Many microspores die after this stress, limiting the efficiency of microspore embryogenesis. Autophagy is a degradation pathway that plays critical roles in ...

Hydrogen Sulfide Generated by L-Cysteine Desulfhydrase Acts Upstream of Nitric Oxide to Modulate Abscisic Acid-Dependent Stomatal Closure
(American Society of Plant Biologists, 2014)
Abscisic acid (ABA) is a well-studied regulator of stomatal movement. Hydrogen sulfide (H2S), a small signaling gas molecule involved in key physiological processes in mammals, has been recently reported as a new component ...

Compartmentalization, a key mechanism controlling the multi-tasking role of SnRK1 complex
(Oxford University Press, 2022)
SNF1-related protein kinase 1 (SnRK1), the plant ortholog of mammalian AMP-activated protein kinase/fungal (yeast) Sucrose Non-Fermenting 1 (AMPK/SNF1), plays a central role in metabolic responses to reduced energy levels ...

Cytochrome c1 exhibits two binding sites for cytochrome c in plants
(Elsevier, 2014)
n plants, channeling of cytochrome c molecules between complexes III and IV has been purported to shuttle electrons within the supercomplexes instead of carrying electrons by random diffusion across the intermembrane bulk ...

The photosynthetic cytochrome c550 from the diatom Phaeodactylum tricornutum
(Springer Verlag, 2016)
The photosynthetic cytochrome c550 from the marine diatom Phaeodactylum tricornutum has been purified and characterized. Cytochrome c550 is mostly obtained from the soluble cell extract in relatively large amounts. In ...

Persulfidation proteome reveals the regulation of protein function by hydrogen sulfide in diverse biological processes in Arabidopsis
(Oxford University Press, 2017)
Hydrogen sulfide-mediated signaling pathways regulate many physiological and pathophysiological processes in mammalian and plant systems. The molecular mechanism by which hydrogen sulfide exerts its action involves ...

Inorganic Polyphosphate in the Microbial World. Emerging Roles for a Multifaceted Biopolymer
(Springer Verlag, 2016)
inorganic polyphosphates (polyP) are linear polymers of tens to hundreds orthophosphate residues linked by phosphoanhydride bonds. These fairly abundant biopolymers occur in all extant forms of life, from prokaryotes to ...
