Packaging design proposal motivated by the identification of damages in Andean blackberry (Rubus glaucus Benth).

ABSTRACT: Andean blackberry is a fruit recognized by its health benefits associated with its high content of bioactive compounds. However, it is also one of the most perishable fruits because it does not have a protective cuticle, and it shows high respiration and ethylene production rates. Furthermore, it is susceptible to microbiological attacks. During harvest and commercialization, the highest percentage of losses is caused by factors such as the maturity stage, harvest practices and containers, and marketing packages. The current work aims at studying the effect of the package on fruit quality, for which the harvested fruits were placed in clamshells, traditional wooden and plastic crates with a capacity of 7 kg. The quality of the fruit was evaluated by counting in situ, damage by bruising, cuts, deformations, microbiological attacks, missing of the peduncle, and non-uniform pollination. Damage analysis included the evaluation of different regression models considering information criteria and significant parameters (P ? 0.05). The use of traditional packages led to higher damage from cuts and bruises. Although in clamshells there was a higher probability of finding healthy fruits, a proposal for its redesign is proposed to guarantee a better quality and shelf life of the Andean blackberry fruits.

Project description:BackgroundThere is an increasing interest in berries, especially blackberries in the diet, because of recent reports of their health benefits due to their high content of flavonoids. A broad range of genomic tools are available for other Rosaceae species but these tools are still lacking in the Rubus genus, thus limiting gene discovery and the breeding of improved varieties.ResultsDe novo RNA-seq of ripe blackberries grown under field conditions was performed using Illumina Hiseq 2000. Almost 9 billion nucleotide bases were sequenced in total. Following assembly, 42,062 consensus sequences were detected. For functional annotation, 33,040 (NR), 32,762 (NT), 21,932 (Swiss-Prot), 20,134 (KEGG), 13,676 (COG), 24,168 (GO) consensus sequences were annotated using different databases; in total 34,552 annotated sequences were identified. For protein prediction analysis, the number of coding DNA sequences (CDS) that mapped to the protein database was 32,540. Non redundant (NR), annotation showed that 25,418 genes (73.5%) has the highest similarity with Fragaria vesca subspecies vesca. Reanalysis was undertaken by aligning the reads with this reference genome for a deeper analysis of the transcriptome. We demonstrated that de novo assembly, using Trinity and later annotation with Blast using different databases, were complementary to alignment to the reference sequence using SOAPaligner/SOAP2. The Fragaria reference genome belongs to a species in the same family as blackberry (Rosaceae) but to a different genus. Since blackberries are tetraploids, the possibility of artefactual gene chimeras resulting from mis-assembly was tested with one of the genes sequenced by RNAseq, Chalcone Synthase (CHS). cDNAs encoding this protein were cloned and sequenced. Primers designed to the assembled sequences accurately distinguished different contigs, at least for chalcone synthase genes.ConclusionsWe prepared and analysed transcriptome data from ripe blackberries, for which prior genomic information was limited. This new sequence information will improve the knowledge of this important and healthy fruit, providing an invaluable new tool for biological research.
