Ect regulation of FLO6, that is a crucial regulator involved in starch synthesis, and by means of indirectly regulating other starch synthesis genes, such as AGPase and SS. In the similar time, NF-YC12 also influences accumulation of storage proteins via straight regulating the amino acid metabolic enzyme OsGS1;three as well as other as yet undetermined seed storage-protein synthases. Also, NF-YC12 interacts with NF-YB1, and they co-regulate sucrose loading through straight regulating SUTs within the aleurone layer. (This figure is available in colour at JXB on-line.)evaluation of the NF-YC12-bound genes showed substantial enrichment of terms for biological processes related to seed and fruit improvement. These benefits reveal a broad regulatory function of NF-YC12 within the establishing rice endosperm. The expression levels of 16 genes related to starch synthesis and seed storage proteins have been reduced inside the nf-yc12 mutant (Fig. 6). Intriguingly, several well-characterized genes encoding starch synthases (OsSSIIIaFLO5, OsAGPL2) and genes related to protein synthesis (GluB1 and GluD1) had been considerably 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 mutation of OsAGPL2 benefits in floury endosperm and severe defects in starch and storage protein synthesis (Tang et al., 2016; Wei et al., 2017). The endospermspecific glutelin gene GluD1 is predominantly expressed within the inner SE, and also the promoter of GluD1 is particularly recognized by RISBZ1 and RPBF (Kawakatsu et al., 2008, 2009). Another glutelin gene, GluB1, has been shown to become involved in storage protein synthesis, as well as 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 2, 3). This recommend that NF-YC12 modulates the approach of storage-substance accumulation by regulating the expression of a number of genes associated with starch and protein biosynthesis, and hence influences seed-related phenotypes of rice. However, further studies are Betahistine site expected to determine whether NF-YC12 regulates these synthesis genes directly or indirectly through grain filling.3778 | Xiong et al.Supplementary dataSupplementary information are accessible at JXB online.
