production of cellulases by macrophomina phaseolina: effect of different cellulosic carbon sources.		1982	6184962
mycotoxicological investigations on maize and groundnuts from the endemic area of mseleni joint disease in kwazulu.	samples of home-grown maize and groundnuts from the endemic area of mseleni joint disease (mjd) during four seasons (1980-1983) were examined mycologically. the mycoflora of these dietary staples included fusarium poae and f. oxysporum, which have been implicated in the aetiology of kashin-beck or urov disease, another osteo-arthrosis endemic in siberia and china. two other species of fusarium, i.e. f. moniliforme and f. equiseti, implicated in syndromes of abnormal bone development in animals, ...	1986	3961620
mutagenic action of phaseolinone, a mycotoxin isolated from macrophomina phaseolina.	phaseolinone was mutagenic to excision-repair-deficient strains of escherichia coli wp2 and also to salmonella typhimurium ta 100. the repair test was indicative of covalent binding of the toxin to dna. the side-chain epoxide and the hydroxy groups of the molecule were found to be essential for mutagenic activity.	1987	3330928
purification and properties of a carboxymethylcellulase from phytopathogenic fungus macrophomina phaseolina.	from the culture filtrate of macrophomina phaseolina, two forms of carboxymethylcellulase were separated by ion-exchange chromatography and designated as cmcase-i and cmcase-ii. cmcase-i was purified following a four-step procedure involving gel filtration on sephadex g-75, con-a sepharose 4b affinity chromatography, fast protein liquid chromatography on mono q anion-exchanger and on superose 12 gel filtration. the final preparation was homogeneous by sds-page, isoelectric focussing in thin laye ...	1989	2628258
effect of some antibiotics on macrophomina phaseolina, a charcoal rot fungus of soybean.	effect of agrimycin-100, ampicillin, griseofulvin and tetracycline on colony growth of macrophomina phaseolina, incitant of charcoal rot of soybean has been studied in vitro. amongst them tetracycline posed most effective inhibiting the growth by 73.9% at 1000 micrograms/ml concentration. on the basis of effectiveness antibiotics have been listed as tetracycline greater than ampicillin greater than griseofulvin greater than agrimycin-100.	1989	2613540
an enzyme immunoassay of phaseolinone and its application in estimation of the amount of toxin in macrophomina phaseolina-infected seeds.	a microtiter plate-based enzyme immunoassay has been developed for phaseolinone, a phytotoxin isolated from the culture filtrate of the plant-pathogenic fungus macrophomina phaseolina (tassi) goid. the smallest amount of phaseolinone detectable by the method is 5 pg per well. the method is validated by comparison with high-performance liquid chromatography and used to confirm and estimate phaseolinone production in seeds infected with the fungus. the degree of seed inhibition correlated well wit ...	1992	1622272
effect of volatile inhibitors from natural and amended soils on germination of sclerotia of macrophomina phaseolina.	studies on volatile soil fungistasis showed that sclerotia of macrophomina phaseolina are not sensitive to volatiles liberated by natural soils with varying ph values. soil amended with alfalfa hay (1%, w/w) liberated volatiles fungistatic to sclerotia only when the assay was performed 2 weeks or less after amendment. chitin-amended soils liberated fungistatic volatiles from 1 to 3 weeks after amendment. indirect evidence indicated that ammonia may be the active volatile in amended soil. it was ...	1976	963611
phosphatase activity in susceptible and resistant cultivars of brassica juncea inoculated with isolates of macrophomina phaseolina and sclerotinia sclerotiorum.	inoculations with isolates of macrophomina phaseolina and sclerotinia sclerotiorum resulted in a significant increase in the acid phosphatase activity of susceptible and resistant cultivars of brassica juncea, which appeared to be related to the disease reaction of different host-pathogen combinations. after an increase on the 6th day of inoculation there was usually a fall in activity on the 12th and 18th days. resistant cultivars showed very poor activity in comparison to their susceptible cou ...	1979	542131
purification and properties of heat-resistant exotoxin produced by macrophomina phaseolina (tassi) goid in culture.	a partially purified preparation of a water-soluble, heat-resistant, nonspecific exotoxin produced by a strain of macrophomina phaseolina, isolated from phaseolus mungo l. could reduce cu++ ions and produced a red colour with 2,4-dinitrophenyl hydrazine reagent. it caused inhibition of seed germination, wilting of cult seedlings, stunted growth of young seedlings and loss of permeability of the cell membrane. seedlings of p. mungo, grown in presence of the toxin showed a slight increase in the c ...	1979	488287
