Differential expression of genes identified from Poncirus trifoliata tissue inoculated with CTV through EST analysis and in silico hybridization

Abstract: Citrus is the most important fruit crop in Brazil and Citrus tristeza virus (CTV) is considered one of the most important pathogens of citrus. Most citrus species and varieties are susceptible to CTV infection. However, Poncirus trifoliata, a close relative of citrus, is resistant to the virus. In order to better understand the responses of citrus plants to the infection of CTV, we constructed expressed sequence tag (EST) libraries with tissues collected from Poncirus trifoliata plants, inoculated or not with … Show more

“…Many diverse “genes” were found differentially regulated in response CTV-CDVd co-infection across both grapefruit varieties. Similar to the results of previous studies on the infection of either CTV [ 53 57 ] or CDVd [ 58 ] in different citrus species and in P. trifoliata , grapefruit metabolic, disease response, structural and phytohormone-related pathways seem to be affected by the co-infection. Genes with known involvement in plant disease responses were mostly grouped into leucine-rich repeat (which include tobacco mosaic virus resistance protein N-like) and ankyrin repeat-containing protein coding genes.…”

“…The predicted amino acid sequence of the cDNA clone exhibited a high sequence similarity to a GLP, and was classified as belonging to a new family of PR proteins, 'PR-16' (see also van Loon et al, 2006). More recently, Cristofani-Yaly et al (2007) constructed expressed sequence tag (EST) libraries with tissues collected from Poncirus trifoliata plants, inoculated or not with citrus tristeza virus, and found a GLP among the genes upregulated at 90 d after inoculation (see also Gandía et al, 2007). Similar results have been reported for Capsicum chinense plants infected with pepper mild mottle virus (PMMoV) (Elvira et al, 2008) and pepper Huasteco yellow vein virus (PHYVV) (Gasca-González et al, 2008).…”

“…Understanding host responses to infection by pathogens facilitates the understanding of plant–pathogen interactions and also provides insights for new control strategies. Changes in the transcriptomes of susceptible Mexican lime (Gandía et al, 2007 ; Liu et al, 2012 ; Yang et al, 2013 ) and sweet orange (Cheng et al, 2016 ) and resistant trifoliate orange (Cristofani-Yaly et al, 2007 ) in response to the infection by mild or severe CTV strains have been well documented. Changes in gene expression in resistant, tolerant, and susceptible hosts in response to CTV were also compared to huanglongbing (HLB; Bowman and Albrecht, 2015 ).…”
