| Aquaculture of nacreous gems, such as cultured pearls, mabé or keshi, is done mostly using different mollusc species grown in countries of the Indo-Pacific region. To date, no single species has been exploited for the simultaneous generation of more than one of these bioproducts, but all require animals with colourful shells. Historically, Pinctada species have mainly been used for nucleated pearl production, selecting the rarer colourful individuals to be used as graft donors. By contrast, colourful Pteria species have mostly been used for mabé production, as the grafting operation for pearl production is associated with low yield. In this study, we report the potential for cumulating cultured pearl and mabé (MP), or keshi and mabé (MK) production, using... |

| Background Cultured pearls are unique gems produced by living organisms, mainly molluscs of the Pinctada genus, through the biomineralization properties of pearl sac tissue. Improvement of P. margaritifera pearl quality is one of the biggest challenges that Polynesian research has faced to date. To achieve this goal, a better understanding of the complex mechanisms related to nacre and pearl formation is essential and can now be approached through the use of massive parallel sequencing technologies. The aim of this study was to use RNA-seq to compare whole transcriptome expression of pearl sacs that had producing pearls with high and low quality. For this purpose, a comprehensive reference transcriptome of P. margaritifera was built based on... |
