Genes differentially expressed between pea accession P665 (resistant to Peyronellaea pinodes) and pea cv. Messire (susceptible to P. pinodes) after inoculation with P. pinodes

Project description:To investigate which are the genes providing resistance to P. pinodes in pea accession P665 we applied MACE-seq to P665 and the susceptible accession Messire inoculated and not inoculated plants. We then performed gene expression profiling analysis using data obtained from MACE-seq at two times points.

Response of a resistant pea accesion to Mycosphaerella pinodes

Project description:Plants of the resistant Pisum sativum subsp. syriacum accession P665 and the susceptible pea cultivar Messire were inoculated with M. pinodes.The experiment was conducted in three replicates. 16, 24 and 48 hours after inoculation RNA was isolated from leaves of infected plants and transcribed into cDNA. For each time point and replicate, Cy-labelled cDNA samples from resistant and susceptible plants were mixed and hybridized to Mt16kOLI1Plus microarray

Seed proteome of pea lines with different responsivity to simultaneous inoculation with arbuscular mycorrhiza fungi and rhizobia

Project description:Legume crops represent the major source of food protein and contribute to human nutrition and animal feeding. An essential improvement of their productivity can be achieved by symbiosis with beneficial soil microorganisms – rhizobia (Rh) and arbuscular mycorrhizal (AM) fungi. The efficiency of these interactions depends on plant genotype. Recently, we have shown that after simultaneous inoculation with Rh and AM, the productivity gain of pea (Pisum sativum L) line K-8274, characterized with a high efficiency of interaction with soil microorganisms (EIBSM), was higher in comparison to a low-EIBSM line K-3358. However, the molecular mechanisms behind this effect are still uncharacterized. Therefore, here, we address the alterations in pea seed proteome, underlying the symbiosis-related productivity gain, and identify 111 proteins, differentially expressed in two lines. The high-EIBSM line K-8274 responded to inoculation by prolongation of seed maturation, manifested by up-regulation of proteins involved in cellular respiration, protein biosynthesis and down-regulation of LEA proteins. In contrast, the low-EIBSM line K-3358 demonstrated lower levels of the proteins, related to cell metabolism. Thus, we assume that the EIBSM trait is due to by prolongation of seed filling that needs to be taken into account when designing production of new pulse crops.

Transcriptional profiling of wilt-resistant and wilt-susceptible chickpea cultivars after Fusarium oxysporum f.sp. ciceri (Foc) inoculation

Project description:Purpose: Molecular analysis of chickpea-Foc interaction; Methods: Four LongSAGE libraries of wilt-resistant and wilt-susceptible chickpea cultivars prepared after Foc inoculation and sequenced using Ion Torrent PGM. Results: Transcriptome analyses revealed expression of several plant defense and pathogen virulence genes with their peculier expression patterns in wilt-resistant and wilt-susceptible chickpea cultivars. Conclusion: The study identified several candidate Foc resistant genes, which can be used for crop improvement after their functional validation.

Proteomics offers insight to the mechanism behind Pisum sativum L. response to Pea Seed-borne Mosaic Virus (PSbMV)

Project description:Pea seed-borne mosaic virus (PSbMV) significantly reduces yields in a broad spectra of legumes. The eukaryotic translation initiation factor has been shown to confer resistance to this pathogen, thus implying that translation and proteome dynamics play a role in resistance. This study presents the results of a proteome-wide analysis of Pisum sativum L. response to PSbMV infection. LC-MS profiling of two contrasting pea cultivars, resistant (B99) and susceptible (Raman) to PSbMV infection, detected >2300 proteins, 116 of which responded to PSbMV ten and/or twenty days post-inoculation. These differentially abundant proteins are involved in number of processes that have previously been reported in the plant-pathogen response, including protein and amino acid metabolism, stress signaling, redox homeostasis, carbohydrate metabolism, and lipid metabolism. We complemented our proteome-wide analysis work with targeted analyses of free amino acids and selected small molecules, fatty acid profiling, and enzyme activity assays. Data from these additional experiments support our findings and validate the biological relevance of the observed proteome changes. We found surprising similarities in the resistant and susceptible cultivars, which implies that a seemingly unaffected plant, with no detectable levels of PSbMV, actively suppresses viral replication.

Comparative transcriptomic analyses of vegetable and grain pea (Pisum sativum L.) seed development

Project description:Pea (Pisum. sativum L.) is a traditional and important edible legume that can be sorted into grain pea and vegetable pea according to their harvested maturely or not. Vegetable pea by eating the fresh seed is becoming more and more popular in recent years. These two type peas display huge variations of the taste and nutrition, but how seed development and nutrition accumulation of grain pea and vegetable pea and their differences at the molecular level remains poorly understood. To understand the genes and gene networks regulate seed development in grain pea and vegetable pea, high throughput RNA-Seq and bioinformatics analysis were used to compare the transcriptomes of vegetable pea and grain pea developing seed. RNA-Seq generated 18.7 G raw data, which was then de novo assembled into 77,273 unigenes with a mean length of 930 bp. Functional annotation of the unigenes was carried out using the nr, Swiss-Prot, COG, GO and KEGG databases. There were 459 and 801 genes showing differentially expressed between vegetable pea and grain pea at early and late seed maturation phases, respectively. Sugar and starch metabolism related genes were dramatically activated during pea seed development. The up-regulated of starch biosynthesis genes could explain the increment of starch content in grain pea then vegetable pea; while up-regulation of sugar metabolism related genes in vegetable pea then grain pea should participate in sugar accumulation and associated with the increase in sweetness of vegetable pea then grain pea. Furthermore, transcription factors were implicated in the seed development regulation in grain pea and vegetable pea. Thus, our results constitute a foundation in support of future efforts for understanding the underlying mechanism that control pea seed development and also serve as a valuable resource for improved pea breeding.

Domestication has altered gene expression in pea seed coat

Project description:In angiosperms, the mature seed consists of an embryo (E), a seed coat (SC), and, in many cases, an endosperm. In contrast to knowledge about embryo and endosperm, we have relatively little knowledge of SC, especially at the genomics level. In this study, we analyzed the gene expression during seed development using the panel of cultivated and wild pea genotypes. We report the comprehensive gene expression changes related both to development as well as domestication status. Analysis of seed developmental stages revealed extensive modification of gene expression between wild pea progenitor and cultivated pea crop. A significant difference in gene expression dynamics appeared between early and late developmental stages D1, D2, and D3, D4, D5 in wild pea genotypes, where the expression was increased 3-5-fold and 5-10-fold, respectively. Our work extends knowledge about the role of the seed coat during pea seed development. We described gene expression dynamic resulting in specific metabolic profiles providing new insight into pea domestication.
