De novo transcriptome sequencing of rough lemon leaves (Citrus jambhiri Lush.) in response to Plenodomus tracheiphilus infection

Project description:Mal secco is one of the most severe diseases of citrus, caused by the necrotrophic fungus Plenodomus tracheiphilus that is widespread in different Mediterranean countries. With the main aim of identifying candidate genes involved in the response of citrus plants to “Mal secco”, we performed a de novo transcriptome analysis of rough lemon seedlings subjected to artificial inoculation of P. tracheiphilus in comparison with plants inoculated with water. The analysis of Differential Expressed Genes (DEGs) highlighted a sharp response triggered by the pathogen as a total of 4,986 significant DEGs (2,865 genes up-regulated and 2,121 down-regulated) have been revealed. The analysis of the most significantly enriched KEGG pathways indicated that a crucial role in the plant response to the fungus is played by genes involved in “Plant hormone signal transduction”, “Phenylpropanoid biosynthesis” and “Carbon metabolism”. The main findings of this work are that under fungus challenge, the rough lemon genes involved both in the light harvesting and the photosynthetic electron flow were significantly down-regulated, thus probably inducing a shortage of energy for cellular functions. Moreover, the systemic acquired resistance (SAR) was activated through the induced salicylic acid cascade. Interestingly, RPM1 interacting protein 4, an essential positive regulator of plant defense, and BIR2, which is a negative regulator of basal level of immunity, have been identified thus representing useful targets for molecular breeding.

Transcriptome analysis of lemon leaves (Citrus limon) infected by Plenodomus tracheiphilus reveals the effectiveness of Pseudomonas mediterranea in priming the plant response to mal secco disease

Project description:The use of Biological Control Agents (BCAs) to cope diseases has received considerable attention owing to its high efficiency and environmental safety. The aim of our study was to investigate the potential role of the Pseudomonas mediterranea pre-treatments in the response of lemon [Citrus limon (L.) Burm. f.] against mal secco, this being a devastating citrus disease caused by the fungus Plenodomus tracheiphilus. RNAseq analysis revealed that the fungus induced a marked reprogramming of the transcriptome, but P. Mediterranea pre-treatments strongly reduced lemon leaf transcriptome modifications and limited the amount of the fungus DNA inside the plant tissue. Furthermore, P. mediterranea prevented the down regulation of the genes involved in the effector triggered immunity (ETI) and the deregulation of genes involved in the main phytohormone’s biosynthesis and perception. As far as we know, this work represents the first report on the analysis of P. tracheiphilus-lemon plant-BCA interaction at molecular level.

Transcriptome Analysis of Plenodomus tracheiphilus Infecting Rough Lemon (Citrus jambhiri Lush.) Indicates a Multifaceted Strategy during Host Pathogenesis.

Project description:The causal agent of mal secco disease is the fungus Plenodomus tracheiphilus, mainly affecting lemon tree survival in the Mediterranean area. Using a fully compatible host-pathogen interaction, the aim of our work was to retrieve the fungus transcriptome by an RNA seq approach during infection of rough lemon (Citrus jambhiri Lush.) to identify crucial transcripts for pathogenesis establishment and progression. A total of 2438 clusters belonging to P. tracheiphilus were retrieved and classified into the GO and KEGG categories. Transcripts were categorized mainly within the "membrane", "catalytic activity", and "primary metabolic process" GO terms. Moreover, most of the transcripts are included in the "ribosome", "carbon metabolism", and "oxidative phosphorylation" KEGG categories. By focusing our attention on transcripts with FPKM values higher than the median, we were able to identify four main transcript groups functioning in (a) fungus cell wall remodeling and protection, (b) destroying plant defensive secondary metabolites, (c) optimizing fungus development and pathogenesis, and (d) toxin biosynthesis, thus indicating that a multifaceted strategy to subdue the host was executed.

Identification of transcription factors potentially involved in the juvenile to adult phase transition in rough lemon (C. jambirhi Lush.)

Project description:The main objective of the present study was to identify citrus transcrition factors putatively involved in the juvenile to adult transition in citrus. A oligonucleotide microarray containing 1152 putative unigenes of citrus transcription factors was used. Rough lemon (C. jambirhi Lush.), were analyzed in two diferent developmental stages, junenile and adult. Four replicates for each sample category were generated and for each genotipe juvenile versus adult samples were compared . Comparative transcriptomic hybridization
