Gene expression of F.graminearum during maize stalk infection

Project description:Fusarium graminearum can infect maize stalk causing Gibberella stalk rot. We want to know the whole genome wide gene profiling when infecting maize stalk. Using lasr capture microdisecction, we captured 8 time points infecting hyphae samples for maize stalk and after two-round amplification, we hybrid the aRNA to Affymetrix array.

Expression profile of maize´s stalk challenged with the corn borer Sesamia nonagrioides

Project description:Stalk borers are major pests for some of the most important crops in the world, such as maize or rice. Plant defense mechanisms against these herbivores have been poorly investigated. The maize´s stalk responds to insect feeding activating defense genes including hormone biosynthetic-related or proteinase inhibitor transcripts. The most outstanding conclusion is that cells in the maize´s stalk undergo cell wall fortification after corn borer tunneling. We performed a gene expression profiling to identify those genes differentially expressed in maize after infestation with the corn borer S. nonagrioides. Four genetically unrelated maize inbred lines (EP39, EP42, CM151 and PB130) were infested at VT (tasseling) developmental stage with a mass of approximately 40 eggs of S. nonagrioides laid on the sheath of the main ear. Another four biological replicates per genotype were used as control. Samples for RNA extraction were harvested fifteen days after infestation.

Comparative proteomic analysis of the defense response to Gibberella stalk rot in maize

Project description:Fusarium graminearum is the causal agent of Gibberella stalk rot in maize stem, resulting maize lodging, yield, quality, and mechanical harvesting capacity. To date, little is known about the maize stem defense mechanism in response to invasion of F. graminearum. This study represents a global proteomic approach to document the infection by F. graminearum. A total of 1,894 differentially accumulated proteins (DEPs) were identified after inoculation of maize plants with F. graminearum. Functional categorization analysis indicated that proteins involved in plant-pathogen interaction were inducible at early stages of infection. We also found that the expression of proteins involved in phenylpropanoid, flavonoid, and terpenoid biosynthesis were up-regulated in response to F. graminearum infection, which may reflect a particular contribution of secondary metabolism in protection against the fungal attack in maize stem. Together, our results indicated that the defense response of maize stem to F. graminearum infection was multifaceted and involved the induction of proteins from various innate immunity related pathways, which had directive significance for molecular genetic breeding of maize disease-resistant varieties.
