NEW HOSTS OF MACROPHOMINA PHASEOLINA IN IRAN
Journal of Plant Pathology, 2012The host range and geographical distribution of Macrophomina phaseolina, the causal agent of charcoal rot or ashy stem blight, was studied in different provinces of Iran during 2006-2008. Plants with signs and symptoms of charcoal rot showed leaf yellowing, blackening of the stem and root rot.

Mitosis and Aneuploidy in the Vegetative Hyphae of Macrophomina Phaseoli
American Journal of Botany, 1967Giemsa and aceto‐orcein staining and an improved squash technique were used to study nuclear behavior in the vegetative hyphae of Macrophomina phaseoli. Stages in nuclear division were similar to those previously recorded in the developing pyenospores except that no spindle was revealed. Mitotic irregularities were common.

ADAPTABILITY OF Macrophomina phaseolina TO QUINTOZENE AND TMTD
Madras Agricultural Journal, 1987Macrophomina phaseolina from cowpea develosed resistance to higher concentration of quintozene when serially transferred from media containing quintezone from lower to higher concentrations. On the contrary it did not show any resistance to TMTD. The in- hibition by quintozene at 2000 ppm was 83.88. and 85,52 per cent when M. phaseolina was transferred

Nuclear Division in the Developing Pycnospores of Macrophomina phaseoli
American Journal of Botany, 1966Nuclear behavior was studied in Giemsa‐stained pycnidial material of Macrophomina phaseoli. The young pycnospore was at first uninucleate but repeated nuclear division occurred as it enlarged, and the mature spore was always multinucleate. The developing spore, therefore, provided a favorable site for observing mitosis.

Microbial transformation of oxandrolone with Macrophomina phaseolina and Cunninghamella blakesleeana
Steroids, 2015Microbial transformation of oxandrolone (1) was carried out by using Cunninghamella blakesleeana and Macrophomina phaseolina. Biotransformation of 1 with M. phaseolina yielded four new metabolites, 11β,17β-dihydroxy-17α-(hydroxymethyl)-2-oxa-5α-androstan-3-one (2), 5α,11β,17β-trihydroxy-17α-methyl-2-oxa-androstan-3-one (3), 17β-hydroxy-17α-methyl-2-oxa-

Detection of double-stranded RNA in Macrophomina phaseolina
Mycologia, 2000One hundred ten isolates of Macrophomi- na phaseolina, the causal agent of charcoal rot of many different plant species, were obtained from Mexico, Somalia, and several locations in the United States, and analyzed for the presence of double- stranded RNA (dsRNA). Twenty-one isolates from the United States and Mexico contained dsRNA ele- ments.

Method for detecting Macrophomina phaseolina
2022The plant pathogen Macrophomina phaseolina is distributed worldwide and has a host range of more than 500 plant species. The fungus attacks crops that are the source of staple foods, and causes yield losses of up to 90% in sunflower, 30-60% in strawberry, 50% in soybean and 70% in corn.

Hydroxylation of (+)-menthol byMacrophomina phaseolina
Biocatalysis and Biotransformation, 2011AbstractBiotransformation of (+)-menthol with Macrophomina phaseolina led to hydroxylations at C-1, C-2, C-6, C-7, C-8 and C-9, with the C-8 position being preferentially oxidized. The resulting metabolites were identified as 8-hydroxymenthol (2), 6R-hydroxymenthol (3), 1R-hydroxymenthol (4), 9-hydroxymenthol (5), 2R,8-dihydroxymenthol (6), 8S,9 ...

Effect of herbicides on survival of Macrophomina phaseolina in soil
Transactions of the British Mycological Society, 1980The effect of five herbicides, EPTC, dinoseb, alachlor, fluorodifen and fluometuron, on the inoculum density of Macrophomina phaseolina (Tassi) Goid. was tested in two field soils. The herbicides were applied at commercially recommended rates. All herbicides tested incited a significant drop in the population of M. phaseolina.
