Patterns of differential gene expression in Brassica napus cultivars infected with Sclerotinia sclerotiorum.

ABSTRACT: SUMMARY The fungal pathogen Sclerotinia sclerotiorum infects a broad range of dicotyledonous plant species and causes stem rot in Brassica napus. To elucidate the mechanisms underlying the defence response, the patterns of gene expression in the partially resistant B. napus cultivar ZhongYou 821 (ZY821) and the susceptible cultivar Westar were studied using a B. napus oligonucleotide microarray. Although maximum differential gene expression was observed at 48 h post-inoculation (hpi) in both cultivars, increased transcript levels were detected in cv. ZY821 at the earlier stages of infection (6-12 hpi) for many genes, including those encoding defence-associated proteins, such as chitinases, glucanases, osmotins and lectins, as well as genes encoding transcription factors belonging to the zi
