Sistance to H. annosum infection. The particular aim of this study was to identify the modifications inside the transcriptome of Scots pine in response to inoculation with H. annosum and to clarify which of these modifications are inoculation-specific. As phytohormones are essential regulators of plant defense responses, the analysis and discussion have been also focused on this aspect. two. Outcomes The transcriptome sequencing resulted in 59.1 million reads with an average length of 78 base pairs (bp). Facts concerning reading count per library and mean study length are supplied in Table 1.Table 1. Read count and read length of transcriptome sequencing libraries.

The reads from manage libraries created no less than one hit with 9190 of 13,405 H. annosum reference transcripts ( 68.56 ); for the wounded sample and inoculated sample libraries, this quantity is, respectively, 9225 and 11,176 ( 68.82 and 83.37 ). Filtering for false discovery rate-adjusted P values identified 54 transcripts “LTE4 Biological Activity differentially ex3 of 20 pressed” amongst control and inoculated samples, 52 of them had been “upregulated”.
