Data from: Non-destructive geographical traceability of sea cucumber (Apostichopus japonicus) using near infrared spectroscopy combined with chemometric methods
Sea cucumber is the major tonic seafood worldwide, and geographical origin traceability is an important part of its quality and safety control. In this work, a non-destructive method for origin traceability of sea cucumber (Apostichopus japonicus) from northern China Sea and East China Sea using near infrared spectroscopy (NIRS) and multivariate analysis methods was proposed. Total fat contents of 189 fresh sea cucumber samples were determined and partial least squares (PLS) regression was used to establish the quantitative NIRS model. The ordered predictors selection (OPS) algorithm was performed to select feasible wavelength regions for the construction of PLS and identification models. The identification model was developed by the principal component analysis combined with Mahalanobis distance (PCA-MD) and Scaling to the first range algorithms. In the test set of the optimum PLS models, the root mean square errors of prediction (RMSEP) was 0.45, and correlation coefficients (R2) was 0.90. The correct classification rates of 100% were obtained both in identification calibration model and test model. The overall results indicated that NIRS method combined with chemometric analysis was a suitable tool for origin traceability and identification of fresh sea cucumber samples from nine origins in China.
Data from: Metal tolerance protein MTP6 affects mitochondrial iron and manganese homeostasis in cucumber
<p><span><b>NOTICE</b></span>: The Editor-in-Chief and Publisher of <i>Journal of Experimental Botany</i> have taken the decision to retract the article related to this dataset due to concern over image manipulation and duplication. Please note, Dryad cannot verify whether the underlying data published is reliable for reuse. Visit this link to view the retraction notice and concerns raised: <a href="https://doi.org/10.1093/jxb/ery342" rel="noopener noreferrer">https://doi.org/10.1093/jxb/ery342</a></p> <p>Members of the cation diffusion facilitator family have been identified in all kingdoms of life. They have been divided into three subgroups – Zn-CDF, Fe/Zn-CDF and Mn-CDF – based on their putative specificity to transported metal ions. The plant metal tolerance 6 (MTP6) proteins fall into the Fe/Zn-CDF subgroup, however their function in iron/zinc transport has not been confirmed yet. Here we characterize the MTP6 protein from cucumber. When expressed in yeast and protoplasts isolated from A. thaliana cells, CsMTP6 localized in mitochondria and contributed to the efflux of iron and manganese from the mitochondria. The immunolocalization of CsMTP6 in cucumber membranes confirmed that CsMTP6 is associated with mitochondria. The root expression and protein level of CsMTP6 were significantly up-regulated in conditions of iron deficiency and iron excess but were not affected by Mn availability. These results indicate that plant MTP6 proteins contribute to the distribution of iron and manganese between the cytosol and mitochondria of plant cells and are regulated by Fe to maintain the mitochondrial and cytosolic iron homeostasis under various Fe availability.</p>
Data from: Molecular mapping and candidate gene analysis for numerous spines on the fruit of cucumber
Number of spines on the fruit is an important quality trait in cucumber. The inheritance and identification of molecular markers for fruit spine density gene can provide a basis for breeding and lay the foundation for gene cloning. Cucumber inbred lines NCG-122 with numerous spines and NCG-121 with few spines were used for genetic analysis and gene mapping in this study. Genetic analysis showed that the numerous spines trait in NCG-122 was qualitative, and a single recessive nuclear gene (ns) controlled this trait. The few spines trait was dominant over the numerous spines trait. In the preliminary genetic mapping of the ns gene, 8 SSR markers were found to be linked to ns, which mapped to chromosome 2 (Chr.2) of cucumber. The closest flanking markers SSR22338 and SSR11596 were linked to the ns gene, with genetic distances of 10.2 and 1.7cM, respectively. One-hundred and thirty pairs of new SSR primers and 28 pairs of Indel primers were developed based on sequence information in the preliminary mapping region of ns. Fifteen SSR markers and 2 Indel markers were identified to be linked to the ns gene after analysis on the F2 mapping population using the new molecular markers. The 2 closest flanking markers, SSRns-127 and SSR04219, were 0.7 and 2.4 cM from ns, respectively. The physical distance between SSRns-127 and SSR04219 was 266.1kb, containing 27 predicted genes. Csa2G285390 was speculated as the probable candidate gene for numerous spines. The accuracy of the closest linked marker to the ns gene, SSRns-127, for MAS breeding was 95.0%.
