Journal ArticleDOI
Identification of genes differentially expressed during interaction of resistant and susceptible apple cultivars (Malus × domestica) with Erwinia amylovora.
Angela M. Baldo,J.L. Norelli,Robert E. Farrell,Carole L. Bassett,Herb S. Aldwinckle,Mickael Malnoy +5 more
TL;DR: Differentially expressed genes were identified by cDNA-AFLP analysis in resistant and susceptible apple genotypes after inoculation with E. amylovora to provide an initial categorization of genes possibly involved in recognition events, early signaling responses the subsequent development of resistance or susceptibility.
Journal ArticleDOI
Differential regulation of two dehydrin genes from peach (Prunus persica) by photoperiod, low temperature and water deficit.
Michael Wisniewski,Carole L. Bassett,Jenny Renaut,Robert E. Farrell,Thomas Tworkoski,Timothy S. Artlip +5 more
TL;DR: The discrepancy between field-collected samples and growth-chamber experiments in the expression of PpDhn1 in response to SD suggests that SD-induced expression of dehydrin genes is complex and may be the result of several interacting factors.
Journal ArticleDOI
Increase in antioxidant gene transcripts, stress tolerance and biocontrol efficacy of Candida oleophila following sublethal oxidative stress exposure
Jia Liu,Jia Liu,Michael Wisniewski,Samir Droby,John L. Norelli,Vera Hershkovitz,Shiping Tian,Robert E. Farrell +7 more
TL;DR: Stress-adapted yeast cells exhibited better control of apple fruit infections by Penicillium expansum and Botrytis cinerea and had initially higher growth rates in apple wounds and the premise that induction of abiotic stress tolerance in biocontrol yeast can improve biocOntrol efficacy by upregulation of genes involved in the amelioration of oxidative stress is supported.
Journal ArticleDOI
Rapid transcriptional response of apple to fire blight disease revealed by cDNA suppression subtractive hybridization analysis
John L. Norelli,Robert E. Farrell,Carole L. Bassett,Angela M. Baldo,Donna A. Lalli,Herb S. Aldwinckle,Michael Wisniewski +6 more
TL;DR: The results indicate that there was a substantial early (1 and 2 hpi) transcriptional response in apple to fire blight disease involving both the down- and up-regulation of host genes.
Journal ArticleDOI
Comparative expression and transcript initiation of three peach dehydrin genes
Carole L. Bassett,Michael Wisniewski,Timothy S. Artlip,Greg Richart,John L. Norelli,Robert E. Farrell +5 more
TL;DR: Primary structure prediction of sequences surrounding the TATA box suggests that conformational transitions associated with decreasing temperature contribute to the regulation of expression of the cold-responsive dehydrin genes.
