Ect regulation of FLO6, which can be a important regulator involved in starch synthesis, and through indirectly regulating other starch synthesis genes, including AGPase and SS. In the same time, NF-YC12 also influences accumulation of storage proteins through directly regulating the amino acid metabolic enzyme OsGS1;3 and other as yet undetermined seed storage-protein synthases. Moreover, NF-YC12 interacts with NF-YB1, and they co-regulate sucrose loading by way of directly regulating SUTs within the aleurone layer. (This figure is readily available in colour at JXB on-line.)evaluation from the NF-YC12-bound genes showed considerable enrichment of terms for biological processes related to seed and fruit improvement. These results reveal a broad regulatory function of NF-YC12 in the developing rice endosperm. The expression levels of 16 genes associated to starch synthesis and seed storage proteins were decreased in the nf-yc12 mutant (Fig. 6). Intriguingly, many well-characterized genes encoding starch synthases (OsSSIIIaFLO5, OsAGPL2) and genes associated to protein synthesis (GluB1 and GluD1) have been significantly down-regulated within the nf-yc12 endosperm. Mutant lines of OsSSIIIaFLO5 show chalky endosperm and decreased starch contents (Ryoo et al., 2007). A loss-of-function AP-18 manufacturer mutation of OsAGPL2 final results in floury endosperm and serious defects in starch and storage protein synthesis (Tang et al., 2016; Wei et al., 2017). The endospermspecific glutelin gene GluD1 is predominantly expressed inside the inner SE, and the promoter of GluD1 is specifically recognized by RISBZ1 and RPBF (Kawakatsu et al., 2008, 2009). One more glutelin gene, GluB1, has been shown to become involved in storage protein synthesis, and also the core motifs in its promoter for seed-specific expression happen to be identified (Wu et al., 2000; Chen et al., 2014). Similarly, nf-yc12 mutants showed floury endosperm and abnormal storage-substance accumulation (Figs two, three). This recommend that NF-YC12 modulates the procedure of storage-substance accumulation by regulating the expression of numerous genes related with starch and protein biosynthesis, and hence influences seed-related phenotypes of rice. Nonetheless, further studies are needed to establish whether NF-YC12 regulates these synthesis genes directly or indirectly in the course of grain filling.3778 | Xiong et al.Supplementary dataSupplementary data are accessible at JXB online.
