Host Range of a Plant Pathogenic Fungus Determined by a Saponin Detoxifying Enzyme

Autor: Michael J. Daniels, Paul Bowyer, B. R. Clarke, Patricia Lunness, Anne Osbourn

Publikováno v: Science. 267:371-374

Antifungal saponins occur in many plant species and may provide a preformed chemical barrier to attack by phytopathogenic fungi. Some fungal pathogens can enzymatically detoxify host plant saponins, which suggests that saponin detoxification may dete

Partial characterization of avenacinase from Gaeumannomyces graminis var. avenae

Autor: Anne Osbourn, J. M. Dow, Michael J. Daniels, B. R. Clarke

Publikováno v: Physiological and Molecular Plant Pathology. 38:301-312

The tritici variety of the take-all fungus Gaeumannomyces graminis causes disease on wheat but is unable to attack oats, while the avenae variety can attack both wheat and oats. The resistance of oats to G. graminis var. tritici has been attributed t

Use of oligonucleotide probes to identify members of two-component regulatory systems in Xanthomonas campestris pathovar campestris

Autor: Anne Osbourn, Barry J.H. Stevens, B. R. Clarke, Michael J. Daniels

Publikováno v: Molecular and General Genetics MGG. 222:145-151

Two-component regulatory systems comprising a sensor and a regulator protein, both with highly conserved amino acid domains, and commonly genetically linked, have been described in a range of bacterial species and are involved in sensing environmenta

The relationship between the rate of starch synthesis, the adenosine 5'-diphosphoglucose concentration and the amylose content of starch in developing pea embryos

Autor: Colin F. Jenner, Alison M. Smith, Kay Denyer, B. R. Clarke

Publikováno v: Planta. 209(3)

Mutations that reduced the rate of starch synthesis in pea (Pisum sativum L.) embryos through effects on enzymes on the pathway from sucrose to adenosine 5'-diphosphoglucose (ADPglucose) also led to a reduction in the amylose content of the starch of

Fungal pathogens of oat roots and tomato leaves employ closely related enzymes to detoxify different host plant saponins

Autor: Anne Osbourn, B. R. Clarke, Patricia Lunness, Michael J. Daniels, Paul Bowyer

Publikováno v: Molecular plant-microbe interactions : MPMI. 8(6)

Antifungal saponins are produced by many plants and have been implicated as preformed determinants of resistance to fungal attack. The importance of saponin detoxification in fungal pathogenesis has recently been demonstrated for the fungus Gaeumanno

Detoxification of Plant Saponins by Fungi

Autor: Paul Bowyer, Michael J. Daniels, B. R. Clarke, Anne Osbourn, Patricia Lunness, Gregory T. Bryan

Publikováno v: Advances in Molecular Genetics of Plant-Microbe Interactions ISBN: 9789401040792

Saponins are glycosylated triterpenoid or steroid molecules which are widely distributed in plants. So far they have been identified in approximately 100 families, including a number of plants which are used as food crops for humans and animals [1].

Extracellular proteases from Xanthomonas campestris pv. campestris, the black rot pathogen

Autor: J. M. Dow, B. R. Clarke, J. L. Tang, D E Milligan, Michael J. Daniels

Publikováno v: Applied and environmental microbiology. 56(10)

Two proteases (PRT1 and PRT2) were fractionated from culture supernatants of wild-type Xanthomonas campestris pv. campestris by cation-exchange chromatography on SP-5PW. Inhibitor experiments showed that PRT 1 was a serine protease which required cal
