Fig. 7From: De novo transcriptome profiling unveils the regulation of phenylpropanoid biosynthesis in unripeĀ Piper nigrum berriesReal-time expression analysis of PAL, C4H, 4CL and CHS. The expression level in unripe berry is too low to be seen near that of YF2 in most cases. High expression was observed in YF1 for PAL and C4HBack to article page
