The application of laser microdissection to in planta gene expression profiling of the maize anthracnose stalk rot fungus Colletotrichum graminicola.
Laser microdissection (LM) offers a potential means for deep sampling of a fungal plant-pathogen transcriptome during the infection process using whole-genome DNA microarrays. The use of a fluorescent protein-expressing fungus can greatly facilitate the identification of fungal structures for LM sampling. However, fixation methods that preserve both tissue histology and protein fluorescence, an...
متن کاملResponse of Sorghum Accessions from Four African Countries against Colletotrichum sublineolum, Causal Agent of Sorghum Anthracnose
Seventy-two sorghum accessions were randomly selected from the Ethiopia, Mali, Sudan, and Uganda germplasm collections maintained by the US National Plant Germplasm System to evaluate variation in anthracnose resistance. The accessions were planted in a randomized complete block design in College Station, Texas during the 2007 and 2008 growing seasons. Twenty-six accessions exhibited a resistan...
متن کاملCotransformation and Targeted Gene Inactivation in the Maize Anthracnose Fungus, Glomerella graminicola.
Cotransformation of Glomerella graminicola was achieved with the G. graminicola genes TUB1R1 (encoding a beta-tubulin which confers resistance to the fungicide benomyl) and PYR1 (encoding orotate phosphoribosyl transferase, which confers pyrimidine prototrophy). The cotransformation frequency was about 30% when selection was for pyrimidine prototrophy (Pyr) and 87% when selection was for benomy...
متن کاملIn vitro photodynamic inactivation of conidia of the phytopathogenic fungus Colletotrichum graminicola with cationic porphyrins.
Photodynamic inactivation (PDI) is an efficient approach for the elimination of a series of microorganisms; however, PDI involving phytopathogenic filamentous fungi is scarce in the literature. In the present study, we have demonstrated the photoinactivating properties of five cationic meso-(1-methyl-4-pyridinio)porphyrins on conidia of the phytopathogen Colletotrichum graminicola. For this pur...
متن کاملA Pictorial Technique for Mass Screening of Sorghum Germplasm for Anthracnose (Colletotrichum sublineolum) Resistance
Globally, the foliar phase of anthracnose is one of the most destructive diseases of sorghum. In most cases, anthracnose resistance screening relies on the use of a spore suspension. This method is usually conducted after sundown and when there is the possibility of dew formation the following morning. Using a spore suspension for sorghum anthracnose field evaluation in College Station, Texas o...
