Cyanogenesis is the process by which hydrogen cyanide is released from endogenous cyanide containing compounds. Many cyanogenic plants release HCN in sufficient quantities to be toxic and, as a result, tend to be avoided by herbivores. However, there are many exceptions with some herbivores either immune to the cyanogenic status of the plant, or in some cases attracted to cyanogenic plants. Thi...

fluorescent pseudomonads are important biocontrol agents showing capability to restrict or suppress phytopathogens, especially the fungal pathogens via production of some inhibitory metabolites and siderophores directly, and promote the plant growth through some different phytohormones. the objective of this research is to screen and introduce pseudomonas fluorescens utpf68 as a new biocontrol ...

Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections. The objective of this study was to investigate the distribution of total cyanide in nine genera (Dolichos, Ginkgo, Hordeum, Linum, Phaseolus, Prunus, Phyllostachys, Phytolacca, a...

Abstract The gases used: ethylene (C 2 H 4 ), hydrogen cyanide (HCN) and nitric oxide (NO) showed a high activity as inductors of germination in primary dormant or non-dormant seeds exposed to stress suboptimal temperatures. So far, research on the role ethylene, has involved these during seed germination. This work describes gas-priming novel method for treating air dry genus Amaranthus servin...

The cyano radical (CN) is one of the most frequently remotely observed species in space, also comets. Data from high-resolution Double Focusing Mass Spectrometer (DFMS) on board Rosetta orbiter, collected inner coma comet 67P/Churyumov-Gerasimenko, revealed an unexpected chemical complexity, and, recently, more CN than expected photodissociation its likely parent hydrogen cyanide (HCN). This wo...

Pseudomonas chlororaphis strain PA23 is a biocontrol agent able to suppress growth of the fungal pathogen Sclerotinia sclerotiorum. This bacterium produces an arsenal of exometabolites including pyrrolnitrin (PRN), phenazine (PHZ), hydrogen cyanide (HCN), and degradative enzymes. Production of these compounds is controlled at both the transcriptional and posttranscriptional levels by the Gac-Rs...

Siderophores are low molecular weight secondary metabolites produced by microorganisms under iron stress as a specific chelator. In the present study, rhizospheric bacterium was isolated from rhizosphere of sesame plants Salem district, Tamil Nadu, India and later identified Bacillus subtilis LSBS2. It exhibited multiple plant-growth-promoting (PGP) traits such hydrogen cyanide (HCN), ammonia, ...

In the current perusal, 12 isolates of Pseudomonas were segregated by rhizospheric soil chickpea (Cicer arietinum) Madhya Pradesh, India. Isolated test organisms characterized morphologically, biochemically and 16S rRNA gene sequencing. Out 12, one isolate designated as P4 was identified aeruginosa through sequencing, which revealed 100% homology with strains DSM 50071 NBRC 12689. The phylogene...

Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. In search of efficient PGPR strains with multiple activities, a total of 150 bacterial isolates belonging to Bacillus, Pseudomonas, Azotobacter and Rhizobium were isolated from different rhizospheric soil of chick pea in the vicinity of Allahabad. These test isolates were bi...

Chirped-Pulse millimetre-Wave (CPmmW) rotational spectroscopy provides a new class of information about photolysis transition state(s). Measured intensities in rotational spectra determine species-isomer-vibrational populations, provided that the rotational populations can be thermalized. The formation and detection of S(0) vinylidene is discussed in the limits of low and high initial rotationa...
