Transcriptional interactions during barley susceptible genotype infection with Cochliobolus sativus

Transcriptional interactions during barley susceptible genotype infection with Cochliobolus sativus A systematic sequencing of expressed sequence tags (ESTs) was used to obtain a global picture of the assembly of barley genes differentially expressed during the hypersensitive reaction of a susceptible genotype in response to an incompatible Cochliobolus sativus pathovar. To identify a large number of plant ESTs, which are induced at different time points, an amplified fragment length polymorphism (AFLP) display of complementary DNA (cDNA) was ulilized. Significant transcriptional changes in the host plant occurred already 4 h post inoculation. Four hundred and fifty six ESTs have been generated, of which 17 (c. 53% up-regulated, 47% down-regulated) have no previously described function. On one hand, the majority of EST-annotations showed protein synthesis, but genes related to signal transduction pathway were also identified. This study provides novel global catalogue of gene regulations involved in C. sativus-barley interaction not currently represented in EST databases. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

A systematic sequencing of expressed sequence tags (ESTs) was used to obtain a global picture of the assembly of barley genes differentially expressed during the hypersensitive reaction of a susceptible genotype in response to an incompatible Cochliobolus sativus pathovar. To identify a large number of plant ESTs, which are induced at different time points, an amplified fragment length polymorphism (AFLP) display of complementary DNA (cDNA) was ulilized. Significant transcriptional changes in the host plant occurred already 4 h post inoculation. Four hundred and fifty six ESTs have been generated, of which 17 (c. 53% up-regulated, 47% down-regulated) have no previously described function. On one hand, the majority of EST-annotations showed protein synthesis, but genes related to signal transduction pathway were also identified. This study provides novel global catalogue of gene regulations involved in C. sativus-barley interaction not currently represented in EST databases.
