Global gene expression of Poncirus trifoliata, Citrus sunki and their hybrids under infection of Phytophthora parasitica

ABSTRACT: A microarray containing 62,876 unigenes selected from CitEST database and prepared by Nimblegen Systems was used for identifying candidate resistance genes against P. parasitica at 48 hours after inoculation Four resistant and four susceptible F1 hybrids were selected from the population derived from the cross between Citrus sunki Hort. ex. Tan. and Poncirus trifoliate (L.) Raf cv. Rubidoux, respectively susceptible and resistant to P. parasitica. It was proposed that differentially expressed genes between resistant and susceptible hybrids and their parents provide essential candidates for identifying transcripts involved in disease resistance A total of 62,876 unigenes (18,712 unigenes of Citrus sinensis; 31,583 unigenes of Citrus reticulata and 12,581 unigenes of Poncirus trifoliate) selected from CitEST database assembled from the EST submitted to NCBI (Genebank accession number EY649559 to EY842485) were used to construct genome-wide oligonucleotide cDNA microarrays by Roche NimbleGen Systems using a multi-step approach to select probes with optimal predicted hybridization characteristics. Three probes were selected per unigene, comprising a probe set, and each probe set is represented on the final array by two replicates. All probes were designed as ‘‘perfect match’’ (PM) oligonucleotides (oligos).

Transcriptome profile of Carrizo citrange roots in response to Phytophthora parasitica infection

Project description:Phytophthora parasitica is one of the most widespread Phytophthora species, which is known to cause root rot, foot rot/gummosis and brown rot of fruits in citrus. In this study, we have analyzed the transcriptome of a commonly used citrus rootstock Carrizo citrange in response to P. parasitica infection using the RNA-seq technology. In total, we have identified 6692 differentially expressed transcripts (DETs) among P. parasitica-inoculated and mock-treated roots. Of these, 3960 genes were differentially expressed at 24 hours post inoculation and 5521 genes were differentially expressed at 48 hours post inoculation. Gene ontology analysis of DETs suggested substantial transcriptional reprogramming of diverse cellular processes particularly the biotic stress response pathways in Carrizo citrange roots. Many R genes, transcription factors, and several other genes putatively involved in plant immunity were differentially modulated in citrus roots in response to P. parasitica infection. Analysis reported here lays out a strong foundation for future studies aimed at improving resistance of citrus rootstocks to P. parasitica.

Genome-wide screening and characterization of long non-coding RNAs involved in flowering development of citrus (Poncirus trifoliata L. Raf.) by RNA sequencing

Project description:To investigate the role of lncRNAs in citrus flowering, paired-end strand-specific RNA sequencing was performed between precocious trifoliate orange and its wild-type. Total 6,584 potential lncRNAs were identified, 51.6% of which came from intergenic regions. It was also observed that 555 lncRNAs were significantly up-regulated, and 276 lncRNAs were down-regulated in precocious trifoliate orange, indicating that lncRNAs could be involved in the regulation of citrus flowering.

Indicated that null segregants lacking transgene have been obtained from the progeny of the backcross of transformants

Project description:Citrus disease resistance breeding has been advanced to introduce CTV resistance of trifoliate orange to citrus. Because the quality of the fruit of trifoliate ogate was low, backcross with citrus was necessary. In the case of citrus, it takes several years from flowering to obtaining next-generation seeds. Therefore, we generated transformants for the early flowering genes (citrus FLOWERING LOCUS T: CiFT) using CiFT co-expression vector construct and promoted generation. In Japan, it is difficult to plant transformants in the field. Therefore, it was decided to select null segregant lacking transgene from backcross progenies. In order to prove that the transgene has been completely removed, it is necessary to prove that no vector conract is present on the genome. Tthis matter was proved by CGH analysis.

miRNA expression data of shoot meristems of trifoliate orange

Project description:In 1976, a spontaneous mutant derived from Poncirus trifoliata (L.) Raf with short juvenile phase, namely, precocious trifoliate orange, was found in Yichang, Hubei province, China. Compared with 6 to 8 years of the wild-type trifoliate orange, almost all of the seedlings germinated from precocious trifoliate orange only have 1 to 2 years’ juvenile period, and 20% seedlings even flowered in the year after germination. Therefore, precocious trifoliate orange is an ideal material for studying the role of miRNAs involved in citrus juvenile and adult developmental stages. To characterize these miRNAs expressed at the juvenile and adult development stages of citrus, Affymetrix miRNA arrays were used to generate miRNA profiles of shoot meristems of trifoliate orange, the results revealed that some miRNAs were down-regulated expressed at adult stage compared with juvenile stage. Detailed comparison of the expression patterns of miRNAs and corresponding target genes revealed the negative correlation between them, while few of them are positively correlated.

Molecular and genetic analysis of resistance to METI-I acaricides in Iranian populations of the citrus red mite Panonychus citri

Project description:The citrus red mite, Panonychus citri, is a major pest on citrus all around the world. Mitochondrial Electron Transport Inhibitors of complex I (METI-I) acaricides such as fenpyroximate have been used extensively to control P. citri populations, which resulted in multiple reports of METI-I resistant populations in the field. In this study, gene expression profile differences between METI-I resistant P. citri populations (Lahijan, Ramsar and Sari) and a susceptible P. citri population (Rasht) from Iran were compared using Illumina RNAseq.

Transcriptional response to soybean aphid infestation in susceptible and resistant soybean plants

Project description:Soybean aphids are phloem-feeding pests that can cause significant yield losses in soybean plants. Soybean aphids thrive on susceptible soybean lines but not on resistant lines. We used microarrays to characterize the soybean plant's transcriptional defense against aphids in two related cultivars, a susceptible line and a resistant line with the Rag1 aphid-resistance gene. We measured trancript levels in leaves after one and seven days of aphid infestation. This was a full-factorial experiment with three factors: soybean variety (susceptible SD01-76R,resistant LD05-16060), aphid treatment (control, aphids), and infestation duration (1 day, 7 days). There were three replicates per treatment, for a total of 24 samples. The experiment was carried out in a growth chamber. At the V3 growth stage, thirty aphids were added to the third trifoliate leaves of the aphid-treated plants. Each plant had a net to prevent aphid movement among different plants. The aphids were removed prior to sampling.

Identifying the genome-wide genetic variation between precocious trifoliate orange and its wild type and developing new markers for genetics research

Project description:To increase our understanding of the genes involved in flowering in citrus, we performed genome resequencing of an early flowering trifoliate orange mutant (Poncirus trifoliata L. Raf.) and its wild type. At the genome level, 3,932,628 single nucleotide polymorphisms (SNPs), 1,293,383 insertion/deletion polymorphisms (InDels), and 52,135 structural variations (SVs) were identified between the mutant and its wild type based on the citrus reference genome. Based on integrative analysis of resequencing and transcriptome analysis, 233,998 SNPs and 75,836 InDels were also identified between the mutant and its wild type at the transcriptional level. Also, 272 citrus homologous flowering-time transcripts containing genetic variation were also identified. GO and KEGG annotation revealed that the transcripts containing the mutant and the wild-type-specific InDel were involved in diverse biological processes and molecular function. Among these transcripts, there were 131 transcripts that were expressed differently in the two genotypes. When 268 selected InDels were tested on 32 genotypes of the three generas of Rutaceae for the genetic diversity assessment, these InDel-based markers showed high transferability. This work provides important information that will allow a better understanding of the citrus genome and that will be helpful for dissecting the genetic basis of important traits in citrus.
