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 ...

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 ...

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 ...

Cysteine and cysteine-related signaling pathways in arabidopsis thaliana
(Oxford University Press, 2014)
Cysteine occupies a central position in plant metabolism because it is a reduced sulfur donor molecule involved in the synthesis of essential biomolecules and defense compounds. Moreover, cysteine per se and its derivative ...

Redox regulation of glycogen biosynthesis in the cyanobacterium synechocystis sp. PCC 6803: Analysis of the AGP and glycogen synthases
(Oxford University Press, 2014)
Glycogen constitutes the major carbon storage source in cyanobacteria, as starch in algae and higher plants. Glycogen and starch synthesis is linked to active photosynthesis and both of them are degraded to glucose in the ...

Beyond toxicity: A regulatory role for mitochondrial cyanide
(Landes Bioscience, 2014)
In non-cyanogenic plants, cyanide is a co-product of ethylene and camalexin biosynthesis. To maintain cyanide at non-toxic levels, Arabidopsis plants express the mitochondrial β-cyanoalanine synthase CYS-C1. CYS-C1 knockout ...

Photoperiodic control of carbon distribution during the floral transition in Arabidopsis
(American Society of Plant Biologists, 2014)
Flowering is a crucial process that demands substantial resources. Carbon metabolism must be coordinated with development through a control mechanism that optimizes fitness for any physiological need and growth stage of ...

Determination of Arabidopsis thaliana telomere length by PCR
(Nature Publishing Group, 2014)
In humans, telomere length studies have acquired great relevance because the length of telomeres has been related to natural processes like disease, aging and cancer. However, very little is known about the influence of ...
