In contrast, the gene expression levels of most of the storage proteins in 132-17, except for GluC, were Due to an unfortunate turn of events, part of a paragraph in dramatically suppressed at 3, 6 and 9 DAP. To identify the the ‘Results’ section of the above-mentioned publication is competitive effects of exogenous protein expression on the missing. The correct text is published below and should be endogenous storage proteins via the transcriptional and/or treated as deﬁnitive by the reader: translational machinery in endosperm cells, we monitored the protein levels of the three different types of storage The accumulation of high levels of OsrAAT in the rice proteins. As shown in Fig. 3, we found that prolamin and endosperm decreased the expression of storage proteins glutelin levels were not obviously affected in 132-10, but were dramatically affected in 132-17. However, globulin According to a previous study, a reduction in the level(s) of was obviously suppressed in both 132-10 and 132-17. In one or a few storage protein(s) can be compensated for by addition, globulin mRNA expression was increased in increases in the levels of other storage proteins (Kawakatsu 132-10, suggesting that the overexpression of OsrAAT in et al. 2010). To further elucidate whether the accumulation the rice endosperm could signiﬁcantly affect the expression of OsrAAT impacts endogenous storage proteins, we of glutelin and prolamin at both the transcriptional and monitored the mRNA expression proﬁles of eight members post-transcriptional levels, whereas globulin could be reg- of glutelin gene family, a globulin gene and four members ulated at the post-transcriptional level (Figs. 2, 3). Taken of the prolamin gene family by quantitative PCR (qPCR). together, these results indicated that the accumulation of As shown in Fig. 2 and Supplemental Fig. 1, the mRNA high levels of OsrAAT in the rice endosperm seriously expression levels of GluA-1, GluB-1, GluB-2, GluB-3, affected endogenous storage protein expression at either GluB-4, Glb-1 and RM1 were signiﬁcantly decreased at 3, the transcriptional or post-transcriptional level. 6 and 9 DAP.
