In this study we present quantitative proteomics data from 3 years of field trials on potato, conducted in northern and southern Sweden and analyze over 3000 proteins per year of the study and complement the proteomic analysis with metabolomic and transcriptomic analyses. Small but consistent differences linked to the longer days (an average of four more hours of light per day) in northern Sweden (20 h light/day) compared to southern Sweden can be observed, with a high correlation between the mRNA determined by RNA-seq and protein abundances. The majority of the proteins with differential abundances between northern and southern Sweden could be divided into three groups: metabolic enzymes (especially GABA metabolism), proteins involved in redox metabolism, and hydrolytic enzymes. The observed differences in metabolic enzyme abundances corresponded well with untargeted metabolite data determined by GC and LC mass-spectrometry. We also analyzed differences in protein abundance between potato varieties that performed relatively well in northern Sweden in terms of yield with those that performed relatively less well. This comparison indicates that the proteins with higher abundance in the high-yield quotient group are more anabolic in their character, whereas the proteins with lower abundance are more catabolic. Our results create a base of information about potato \"field-omics\" for improved understanding of physiological and molecular processes in field-grown plants, and our data indicate that the potato plant is not generally stressed by extremely long days.", "doi": "10.1016/j.plaphy.2024.109032", "pmid": "39181085", "labels": {"NGI Uppsala (SNP&SEQ Technology Platform)": "Service", "NGI Short read": "Service", "National Genomics Infrastructure": "Service", "Swedish Metabolomics Centre": "Service"}, "xrefs": [{"db": "pii", "key": "S0981-9428(24)00700-9"}], "notes": [], "created": "2024-10-21T11:17:16.284Z", "modified": "2025-10-17T13:03:13.007Z"}, {"entity": "publication", "iuid": "27a23a0971e94ccd9e005fc4bf4b193b", "links": {"self": {"href": "https://publications.scilifelab.se/publication/27a23a0971e94ccd9e005fc4bf4b193b.json"}, "display": {"href": "https://publications.scilifelab.se/publication/27a23a0971e94ccd9e005fc4bf4b193b"}}, "title": "Transcriptome and metabolome profiling identify factors potentially involved in pro-vitamin A accumulation in cassava landraces.", "authors": [{"family": "Olayide", "given": "Priscilla", "initials": "P"}, {"family": "Alexandersson", "given": "Erik", "initials": "E"}, {"family": "Tzfadia", "given": "Oren", "initials": "O"}, {"family": "Lenman", "given": "Marit", "initials": "M"}, {"family": "Gisel", "given": "Andreas", "initials": "A"}, {"family": "Stavolone", "given": "Livia", "initials": "L"}], "type": "journal article", "published": "2023-06-00", "journal": {"title": "Plant Physiol Biochem", "issn": "1873-2690", "volume": "199", "pages": "107713", "issn-l": null}, "abstract": "Cassava (Manihot esculenta Crantz) is a predominant food security crop in several developing countries. Its storage roots, rich in carbohydrate, are deficient in essential micronutrients, including provitamin A carotenoids. Increasing carotenoid content in cassava storage roots is important to reduce the incidence of vitamin A deficiency, a public health problem in sub-Saharan Africa. However, cassava improvement advances slowly, mainly due to limited information on the molecular factors influencing \u03b2-carotene accumulation in cassava. To address this problem, we performed comparative transcriptomic and untargeted metabolic analyses of roots and leaves of eleven African cassava landraces ranging from white to deep yellow colour, to uncover regulators of carotenoid biosynthesis and accumulation with conserved function in yellow cassava roots. Sequence analysis confirmed the presence of a mutation, known to influence \u03b2-carotene content, in PSY transcripts of deep yellow but not of pale yellow genotypes. We identified genes and metabolites with expression and accumulation levels significantly associated with \u03b2-carotene content. Particularly an increased activity of the abscisic acid catabolism pathway together with a reduced amount of L-carnitine, may be related to the carotenoid pathway flux, higher in yellow than in white storage roots. In fact, NCED_3.1 was specifically expressed at a lower level in all yellow genotypes suggesting that it could be a potential target for increasing carotenoid accumulation in cassava. These results expand the knowledge on metabolite compositions and molecular mechanisms influencing carotenoid biosynthesis and accumulation in cassava and provide novel information for biotechnological applications and genetic improvement of cassava with high nutritional values.", "doi": "10.1016/j.plaphy.2023.107713", "pmid": "37126903", "labels": {"Swedish Metabolomics Centre": "Service"}, "xrefs": [{"db": "pii", "key": "S0981-9428(23)00224-3"}], "notes": [], "created": "2023-08-30T07:04:17.911Z", "modified": "2025-10-17T13:03:13.885Z"}], "created": "2023-08-30T07:04:17.935Z", "modified": "2023-08-30T07:04:17.935Z"}
