Abstract

Transcriptome analysis of Pinus sylvestris seedlings under infection with Fusarium sp. has been performed to screen and quantify the transcripts of protective PR genes and the genes involved in cell cycle regulation (CDK, CKS, and cyclin). Under conditions of biotic stress, a decrease in transcriptional activity of the genes of cell cycle regulators was found, with increased expression of PR-gens. The results obtained expand our knowledge about genetic determination of resistance factors and evaluation of adaptive features of P. sylvestris juvenile plants to infections.
