ima genome f13 draft genome sequences of ambrosiella cleistominuta cercospora brassicicola c citrullina Physcia stellaris and teratosphaeria pseudoeucalypti
IMA fungus, 2020Co-Authors: Markus P Wilken, Janneke Aylward, Ramesh Chand, Felix Grewe, Frances A Lane, Shagun Sinha, Claudio G Ametrano, Isabel DistefanoAbstract:Draft genomes of the fungal species Ambrosiella cleistominuta, Cercospora brassicicola, C. citrullina, Physcia stellaris, and Teratosphaeria pseudoeucalypti are presented. Physcia stellaris is an important lichen forming fungus and Ambrosiella cleistominuta is an ambrosia beetle symbiont. Cercospora brassicicola and C. citrullina are agriculturally relevant plant pathogens that cause leaf-spots in brassicaceous vegetables and cucurbits respectively. Teratosphaeria pseudoeucalypti causes severe leaf blight and defoliation of Eucalyptus trees. These genomes provide a valuable resource for understanding the molecular processes in these economically important fungi.

Current Genetics Lower Eukaryotes and Organelles Heterogeneity of intron presence or absence in rDNA genes of the lichen species and Physcia aipolia P. stellaris
2020Co-Authors: Dawn M Simon, Cora L Hummel, Sara L Sheeley, Debashish BhattacharyaAbstract:Intron origin and evolution are of high interest, yet the rates of insertion and loss are unclear. To investigate their spread, we studied ribosomal (r)DNA introns from the closely related lichens and . Both taxa are replete with rDNA spliceosomal introns and autocatalytic group I introns, many of which show presence/absence polymorphism when screened with the PCR approach. This initially suggested that could be a model for studying intron retention and loss. However, during the course of a population-level analysis, we discovered widespread intron presence/absence heterogeneity within lichen thalli. To address this result, we sequenced multiple clones encoding nuclear rDNA and the single-copy elongation factor-1 ( ) from individual thalli. These data showed extensive rDNA heterogeneity within individuals, rather than the presence of multiple fungi within a thallus. Our results suggest that considerable care must be taken when interpreting intron presence/absence in lichen rDNA, an observation that has general implications for the study of rDNA intron evolution.

Heterogeneity of intron presence or absence in rDNA genes of the lichen species Physcia aipolia and P. stellaris
Current Genetics, 2005Co-Authors: Dawn M Simon, Cora L Hummel, Sara L Sheeley, Debashish BhattacharyaAbstract:Intron origin and evolution are of high interest, yet the rates of insertion and loss are unclear. To investigate their spread, we studied ribosomal (r)DNA introns from the closely related lichens Physcia aipolia and P. stellaris .

However, during the course of a population-level analysis, we discovered widespread intron presence/absence heterogeneity within lichen thalli. To address this result, we sequenced multiple clones encoding nuclear rDNA and the single-copy elongation factor-1α ( EF-1 α) from individual thalli. These data showed extensive rDNA heterogeneity within individuals, rather than the presence of multiple fungi within a thallus. Our results suggest that considerable care must be taken when interpreting intron presence/absence in lichen rDNA, an observation that has general implications for the study of rDNA intron evolution.
