“…In several cases, leaves withered, but the plant continued its development to complete its cycle, and showed the characteristic symptoms when the smut panicle emerged. Snetselaar and Mims (1994), Martinez et al (1999) and Martinez et al (2002) observed that aft er inoculation of S. reilianum, young plants were slightly chlorotic and contained scattered hyphae. Th e latter developed in the epidermal cells and vascular parenchyma, but not in the intercellular spaces.…”

Th e eff ect of loose kernel smut fungus Sporisorium cruentum on Sorghum halepense (Johnson grass) was investigated in vitro and in greenhouse experiments. Smut infection induced a decrease in the dry matter of rhizomes and aerial vegetative parts of the plants evaluated. Moreover, the diseased plants showed a lower height than controls. Th e infection resulted in multiple smutted buds that caused small panicles infected with the fungus. In addition, changes were observed in the structural morphology of the host. Leaf tissue sections showed hyphae degrading chloroplasts and vascular bundles colonized by the fungus. Subsequently, cells collapsed and widespread necrosis was observed as a symptom of the disease. Th e pathogen did not colonize the gynoecium of Sorghum plants until the tassel was fully developed. Th e sporulation process of the fungus led to a total disintegration of anthers and tissues. When panicles were inspected before emergence, fungal hyphae were observed on fl oral primord. Histological sections of panicles showed fungal hyphae located in the parenchyma tissue and the nodal area. Infection occurred in the fl oral primordium before the tassel had fully developed and emerged from the fl ag leaf. Grains were replaced by sori surrounded by a thin membrane that usually was broken before or aft er the emergence of the panicle. Th e results, together with the signifi cant decrease of the dry matter of rhizomes and seeds of S. halepense, suggest that S. cruentum could be considered as a potential biocontrol agent in the integrated management of this weed.

“…Root infection was performed as described by Martinez et al (2002). Seeds of a variety highly susceptible to Ustilago maydis (LMZ66-Limagrain, France) were surface-sterilized in 5% (w/v) chloramine T (Sigma, France) and place on PDA medium at 24°C during 4 days.…”

“…The quantification was done with the aid of a Neubauer haemocytometer. When the basidiospore concentration reached 10 6-8 basidiospores • ml −1 , the samples were placed in the refrigerator (5°C) to be used for future inoculations (Wilson and Frederiksen 1970;Martinez et al 2002).…”

Abstract:The aims of this study were to clarify the reproductive biology of the Ustilago filiformis Schrank, as causal agent of the stripe smut of Glyceria multiflora, determine the infection process of the pathogen and analyze the histological changes associated hostGlyceria any fungus attack. Moreover, the life cycle of the fungus was elucidated for the first time. Both teliospores and basidiospores were found to be equally efficient in producing the infection in Glyceria plants after the plants had been inoculated. These results constitute an important contribution for the understanding of the epidemiology of the disease.
