Fig. 1From: Developmental characteristics of pearl oyster Pinctada fucata martensii: insight into key molecular events related to shell formation, settlement and metamorphosisGenes coding for shell proteins expression model at different development stage in P. f. martensii. a. the expression pattern of shell protein coding genes at different development stage in P. f. martensii. The y-axis is the normalized RPKM value.
