“…Interestingly, the strong grain weight-associated SNP allelic variants-containing RAV1AAT and CARGCW8GAT known cis -regulatory elements/TF-binding sites of two genes identified are known to be involved in growth and development by transcriptional regulation/interaction and preferential/tissue-specific expression of many important TF genes in seeds of rice (Zheng et al, 2009; Bajaj et al, 2015b). The direct interactions of the RAV1 (related to ABI3/VP1 ) and CArG TF DNA-binding protein with other TF genes including MADS-domain protein-encoding genes, SEPALLATA3 and AGAMOUS-like 15 ( AGL15 ), respectively, have been established to be the key regulators of seed development in Arabidopsis (Tang and Perry, 2003; Le et al, 2010; Agarwal et al, 2011; Zhang et al, 2015). Therefore, it would be interesting to study transcriptional regulation and binding/interactions of two SCP and GH genes at known cis -regulatory element regions/TF-binding sites with MADS TF genes in controlling grain weight/size of rice.…”
