Senescent Sweetening in Potato Tubers is Associated with a Reduction in Plastidial Glucose-6-Phosphate/Phosphate Encoding Transcripts: Microarray set 2

ABSTRACT: Senescent sweetening results in the accumulation of reducing sugars in potato tubers following extended periods of storage at moderate temperatures, used to avoid the separate condition of cold-induced sweetening. Transcriptional profiling was performed using microarrays on potato genotypes with contrasting response; cultivars Arsenal and VR808, were considered to be senescent sweetening susceptible and resistant, respectively. Tubers were stored at 13 °C for two weeks prior to the application of chlorpropham (CIPC) to inhibit sprouting, and then transferred for long-term storage in the dark at 9 °C for different periods. Data indicated changes in carbohydrate metabolism were associated with the onset of senescent sweetening. Data set 2

Quantitative proteomic analysis of differentially expressed proteins in tubers of potato plants differing in resistance to Dickeya solani

Project description:To identify differently expressed proteins in tuber tissue of potato cultivars and diploid interspecific hybrids of Solanum, differing in resistance to Dickeya solani, comparative analysis was performed. Two highly resistant (Bea and Humalda) and three susceptible (Irys, Katahdin, Ulster Supreme) potato cultivars, as well as the highly resistant (DG 00-270) and the susceptible (DG 08-305) diploid clones, were studied. DG 00-270 exhibited higher resistance to D. solani than the cultivars Bea and Humalda. Proteins were extracted from wounded potato tubers inoculated with bacteria at an early symptomatic phase and from controls, i.e., intact tubers and wounded mock-inoculated tubers. Protein profiles were analyzed using nano-liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS/MS).

Project description:Two small RNA libraries and 2 degradome libraries were constructed from potato tubers stored at room temperature or exposed to cold stress for deep sequencing. Through small RNA sequencing, 53 known miRNAs and 59 novel miRNAs were identified. Seventy genes were identified as miRNA targets by degradome sequencing.

A label-free quantitative proteomic analysis reveals amino acids and carbohydrate metabolic enzymes are differentially accumulated in three Jerusalem artichoke (Helianthus tuberosus L.) cultivars exhibiting phenological tuberization characters

Project description:Jerusalem artichoke (JA) tubers are an important bio-economy developing crop because of its invaluable bioproducts in both food and biofuel aspects. However, the molecular mechanism of its tuberization, and the differences among different cultivars have been little studied to date. Here, we conducted a comparative proteome profiling of the JA tubers of three different cultivars including PJA, DJA, and HJA, showing phenotypic characteristics. Tuber epidermal pigmentation and underground tuberization habit were different phenological characters in the three cultivars and inulin content was also a physiological character exceptionally DJA regardless of the similar level of total carbohydrate amount. We identified a total of 420 proteins in the tubers and out of 114 showed significantly modulated among the cultivars. GO classification of the DEPs revealed biosynthesis amino acid and carbohydrate metabolic enzymes were differentially expressed in the three cultivar tubers. Integrated physiological inulin content and the biosynthetic protein expression levels among the cultivars suggest that Sucrose:sucrose 1-fructosyltransferase (1-SST) prioritizes inulin biosynthesis rather than rate-limiting enzyme fructan:fructan 1-fructosyltransferases (1-FFT). Furthermore, we confirmed the relationship between transcript-protein expression levels was in discord within inulin biosynthesis enzymes 1-SST and 1-FFT with the terms in previous RT-qPCR results using the same tubers. Our data represent the first report that comparative proteome profiling in JA tubers among the different cultivars and provides the metabolic and molecular basis for understanding carbohydrate metabolism in storage tuber tissue.

Insight on genes affecting tuber development in potato upon Potato spindle tuber viroid (PSTVd) infection

Project description:Potato (Solanum tuberosum L) is a natural host of Potato spindle tuber viroid (PSTVd) which can cause characteristic symptoms on developing plants including stunting phenotype and distortion of leaves and tubers. PSTVd is the type species of the family Pospiviroidae, it can replicate in the nucleus and the viroid RNA moves systemically in infected plants. Its KF440-2 strain can cause severe symptoms in potato. It is not well understood how the viroid can affect host genes for successful invasion and which genes show altered expression levels upon infection. In this study, we used a high-scale method to identify differentially expressed genes in potato. We have identified defence, stress and sugar metabolism related genes having altered expression levels upon infection. Additionally, hormone pathways connected genes showed up- or down-regulation. Our primary focus is on the identification of genes which can affect tuber formation as the viroid infection can strongly influence tuber development, especially tuber shape is affected. DWARF1/DIMINUTO, Gibberellin 7-oxidase and BEL5 protein were identified and validated which showed differential expression in viroid infected tissues suggesting that gibberellin and brassinosteroid pathways have a possible role in tuber development upon PSTVd infection.

Potato tuber gene expression during spraing formation in response to Tobacco rattle virus infection

Project description:Field-grown tubers of potato were examined for infection by Tobacco rattle virus and consequent production of corky ringspot or spraing symptoms. A microarray study identified tuber genes that are differentially expressed in response to TRV infection and to spraing production, showing that hypersensitive response (HR) pathways are activated in spraing-symptomatic tubers. This was confirmed by quantitative RT-PCR (Q-RT-PCR) of a selected group of HR-related genes and by histochemical staining of excised tuber tissue with spraing symptoms. Q-RT-PCR of TRV in different areas of the same tuber slice showed that non-symptomatic areas contained higher levels of virus than did spraing-symptomatic areas. This suggests that spraing formation is associated with an active plant defence that reduces the level of virus in the infected tuber. Expression of two plant defence genes was similarly upregulated in spraing-symptomatic tubers that were infected with another virus, Potato mop-top-virus, suggesting that spraing is a generalised response to virus infection of tubers.

Light regulation of chlorophyll and glycoalkaloid biosynthesis during tuber greening of potato S. tuberosum

Project description:Potato, S. tuberosum, is one of the most important global crops, but has high levels of waste due to tuber greening under light, which is associated with the accumulation of neurotoxic glycoalkaloids. Here, we have investigated the effect of monochromatic far-red, red, and blue light on the regulation of chlorophyll and glycoalkaloid accumulation in tubers of a commercial variety, King Edward. Transcriptomic analysis of tubers exposed to red, blue, and white light showed that light induction of photosynthesis and tetrapyrrole-related genes grouped into two distinct patterns with one group showing much stronger induction in blue at 6 h and 24 h and a second group showing only red induction at 24 h.

Transcriptional profiling of S. tuberosum cv. Agria leaf and tuber samples after mild heat stress

Project description:The consequences on tuber transcriptome of a short heat period during tuber development was investigated in this study with special regard to the development of secondary tuber growth. Plants were grown for 47 days in the greenhouse under ambient conditions (21Â°C/ 19Â°C, 16h light, 8h dark) before application of mild heat stress temperatures (29Â°C/27Â°C) to one group of plants for 7 days and a stress release period on control temperature for 2 more weeks until harvest. Leaves were sampled before the heat period, at the end of the heat period and at harvest, two weeks after stress release. Tuber samples were taken at harvest. Tubers grown at normal temperatures and exhibiting a normal growth phenotype were used as control. Tubers subjected to the heat treatment and exhibiting a second-growth phenotype (chain tubers) were grouped into primary (attached to stolon from plant) and secondary tubers (attached to stolon from primary tuber).
