Abstract Salicylic acid (SA)‐mediated induction of systemic resistance by Pseudomonas aeruginosa strain 7NSK2 and P. fluorescens CHA0 against soil‐borne fungi viruses have been reported. The role SA biosynthesis in the enhancement defence mechanism plant‐parasitic nematodes these bacterial strains tomato is not known. To better understand importance rhizobacteria‐mediated suppression root‐knot nematodes, biocontrol potential SA‐negative or SA‐overproducing mutants Meloidogyne javanica was...

Abstract The two rhizobacteria Pseudomonas aeruginosa strain IE‐6S + and P. fluorescens CHA0 used as bare root‐dip treatment or soil drench substantially reduced Meloidogyne javanica juvenile penetration into tomato roots under glasshouse conditions. To better understand the basis of antagonism, mode action bacterial antagonists was investigated. ability inoculants to stimulate induced systemic resistance against nematode demonstrated in split‐root‐trials, where root system a single plant...

Monoclonal antibodies (mAbs) represent one of the most prevalent FDA-approved modalities for treating autoimmune diseases, infectious and cancers. However, discovery development therapeutic remains a time-consuming expensive process. Recent advancements in machine learning (ML) artificial intelligence (AI) have shown significant promise revolutionizing antibody optimization. In particular, models that predict biological activity enable in-silico evaluation binding functional properties; such...

To determine the influence of soil-borne fungus Trichoderma harzianum on biocontrol performance Pseudomonas fluorescens strain CHA0 and its 2,4-diacetylphloroglucinol (DAPG) overproducing derivative CHA0/pME3424 against Meloidogyne javanica.Amendment culture filtrate (CF) or methanol extract CF a T. Th6 to P. growth medium enhanced production nematicidal compound(s) by bacterial inoculants in vitro. In addition, bacteria overwhelmingly expressed phl'-'lacZ reporter gene when was amended with...

Abstract The ecology of Pochonia chlamydosporia in soil and its interaction with both plant nematode hosts are important for the successful exploitation fungus as a biological control agent. Differences saprotrophism parasitism were assessed biotypes P. , which had originated from eggs cyst or root‐knot nematodes. Colonisation soils different textures (compost, sandy loam loamy sand) measured by numbers colony‐forming units, differed greatly. Most more abundant sterilised compared...

Increasing power demands and equally growing environmental problems have lead the people to think, develop, implement new clean sources of energy address both issues. This article presents an optimal system configuration for reliable generation unreliable grid‐tied photovoltaic a household in Larkana, Pakistan.

To improve the efficacy of Pseudomonas fluorescens CHA0 and its genetically modified (GM) derivatives by adding ammonium molybdate to control Meloidogyne javanica, root-knot nematode in mungbean.Culture filtrate P. GM derivative (antibiotic overproducing strain CHA0/pME3424 antibiotic-deficient CHA89) obtained from nutrient broth yeast extract medium amended with 1, 2 or 4 mm (NH4-Mo) caused substantial mortality M. javanica juveniles vitro. applied conjunction NH4-Mo greater reduction...

Abstract Pseudomonas fluorescens strain CHA0 and its antibiotic overproducing derivative CHA0/pME3424 repeatedly reduced Meloidogyne incognita galling on tomato, brinjal, mungbean soya bean roots but not in chilli. An antibiotic‐deficient derivative, CHA89, did reduce nematode invasion any of the plant species tested. When were compared, bacterial inoculants afforded better protection to against root‐knot nematodes than brinjal Antibiotic markedly fresh shoot weights chilli while CHA89...

Abstract Understanding the environmental factors that influence rhizosphere and inner root colonization of disease‐suppressive strains fluorescent pseudomonads is an essential step towards improving level reliability their biocontrol activity. Soil amendment with Zn at 0.8 or 1.6 mg/kg soil alone in combination Pseudomonas aeruginosa IE‐6S + significantly reduced nematode penetration tomato roots. applied did not reduce infection caused by Macrophomina phaseolina Fusarium solani but when...

This study is focused on the search for new energy levels and classification of weak spectral lines by analysing hyperfine (hf) spectra. Laser-induced fluorescence spectroscopy as well optogalvanic were applied to measure hf structure Lanthanum transitions. Free La atoms are produced excited in a hollow-cathode discharge. Ninety-six have been analysed range from 430 742 nm using tunable single-mode cw dye laser operating with different dyes. Ninety-four these new, which means they not listed...

Laser excitation of an Ar–La plasma, generated in a hollow cathode discharge lamp, has allowed to us observe huge number spectral lines that could not be interpreted as transitions between already known La energy levels. From the observed hyperfine structure patterns and fluorescence lines, we derived 37 new levels, all with even parity, range 38 000 cm−1 43 cm−1. The existence these levels was then proved by excitations from other lower

The hyperfine structure of weak La I lines was experimentally investigated using laser optogalvanic spectroscopy in a hollow cathode discharge lamp. More than 100 were and 40 new energy levels discovered, most them having even parity. magnetic interaction constants A some cases the electric quadrupole B for these determined. All newly discovered confirmed either by additional excitations (from other known levels) or Fourier transform spectrum which could now be classified.

Abstract Bare‐root‐dip treatment or soil drench with Pseudomonas aeruginosa strain IE‐6S + and P. fluorescens CHA0 significantly suppressed Rhizoctonia solani the bacterial efficacy was more pronounced in presence of low inoculum level fungus. The two bacteria afforded better protection to tomato roots against R. during early growth stages roots. There a significant difference between root‐dip both inoculants. ability antagonistic induce systemic resistance demonstrated split‐root trials,...

The hyperfine (hf) structure of some spectral lines the praseodymium atom has been investigated by laser-induced fluorescence method in a hollow cathode discharge lamp. We report discovery 18 new energy levels even parity and 22 odd their magnetic dipole hf interaction constants A .
