Hydrogen sulfide: a new node in the abscisic acid-dependent guard cell signaling network?
Hydrogen sulfide (H2S) is fast emerging as a new gaseous signaling molecule in organisms as diverse as bacteria, fungi, worms, humans, and plants (Kabil et al., 2014). Although H2S has long been known to be toxic at high concentrations because of its ability to inhibit the mitochondrial cytochrome C oxidase, at much lower concentrations it has been proposed to act as a signal transmitter in con...
متن کاملOutcome after hydrogen sulphide intoxication.
AIM Hydrogen sulphide (H2S) intoxication in man is frequently associated with a fatal outcome. In small animal models hydrogen sulphide has demonstrated profound protection against hypoxia. No reports that focus on a potential protective effect in humans have been published. METHODS The frequency and outcome of a large cohort of hydrogen sulphide intoxications is described. RESULTS From 198...
متن کاملHydrogen sulphide production by bacteria.
Hydrogen sulphide production by growing cultures and non-multiplying suspensions was compared and the factors influencing the sensitivity of the tests were investigated. Cysteine hydrochloride (0.01 yo) was added to Lemco broth to provide a medium with a standard source of sulphur. H,S was detected with lead acetate papers more readily than by lead acetate agar. Suspensions were tested with cys...
متن کاملGuard-cell signalling for hydrogen peroxide and abscisic acid.
Guard cells can integrate and process multiple complex signals from the environment and respond by opening and closing stomata in order to adapt to the environmental signal. Over the past several years, considerable research progress has been made in our understanding of the role of reactive oxygen species (ROS) as essential signal molecules that mediate abscisic acid (ABA)-induced stomatal clo...
متن کاملFatal hydrogen sulphide poisoning in unconfined spaces.
Fatal hydrogen sulphide poisoning usually occurs in confined spaces. We report two fatal accidents in unconfined spaces. The first accident caused the death of three workers who entered an unconfined room in a silo of sludge at the same time that a truck dumped several tons of sludge from water purification stations. The hydrogen sulphide that had accumulated inside the silo spilled out into th...
