Quantitative proteomic analysis of the sugarcane defense responses incited by Acidovorax avenae subsp. avenae causing red stripe

Résumé

The causal agent of red stripe, Acidovorax avenae subsp. avenae (Aaa), can incite significant economic losses during sugarcane production. Proteomics is a useful tool for the comprehensive identification of defense response proteins in plants. In this study, isobaric tags for relative and absolute quantification (iTRAQ)-based proteomics was used to identify proteins that were produced in sugarcane in defense to Aaa in two Saccharum spp. cultivars: ROC22 (resistant to red stripe) and MT11-610 (susceptible). Defense response was evaluated at 0 h (mock inoculation) and 24 h after inoculation with the bacterial pathogen, and 10,502 high-confidence proteins and 1962 differentially expressed proteins (DEPs) were identified. These DEPs included 1027 proteins (671 upregulated, 354 downregulated) in ROC22 and 1130 proteins (566 upregulated, 564 downregulated) in MT11-610. Gene ontology analysis revealed that most DEPs were clustered in the metabolic, single-organism metabolic, and oxidation-reduction processes, and in catalytic activity. In a KEGG analysis, these proteins belonged to common pathways such as secondary metabolite biosynthesis and biosynthesis of phenylpropanoids. Thirty-six DEPs were identified, especially epoxide hydrolase 1, dynamin-related protein 1C-like, cytochrome oxidase subunit I, FK506-binding protein, acetoacetyl CoA thiolase isoform 2, anthocyanidin 3-o-glucosyltransferase, ubiquitin carboxyl-terminal hydrolase 4, protein disulfide isomerase-like protein, and jumonji-like transcription factor family protein. These nine proteins were characterized by enhanced expression with >= 1.5-fold increases in resistant ROC22 versus susceptible MT11-610, and are therefore biomarker candidates in the sugarcane response against Aaa. These data could be very useful in molecular breeding for sugarcane resistance to red stripe.
