Table_1_Regulator Network Analysis of Rice and Maize Yield-Related Genes.xls

Rice and maize are the principal food crop species worldwide. The mechanism of gene regulation for the yield of rice and maize is still the research focus at present. Seed size, weight and shape are important traits of crop yield in rice and maize. Most members of three gene families, APETALA2/ethylene response factor, auxin response factors and MADS, were identified to be involved in yield traits in rice and maize. Analysis of molecular regulation mechanisms related to yield traits provides theoretical support for the improvement of crop yield. Genetic regulatory network analysis can provide new insights into gene families with the improvement of sequencing technology. Here, we analyzed the evolutionary relationships and the genetic regulatory network for the gene family members to predicted genes that may be involved in yield-related traits in rice and maize. The results may provide some theoretical and application guidelines for future investigations of molecular biology, which may be helpful for developing new rice and maize varieties with high yield traits.

水稻与玉米是全球范围内的主要粮食作物物种。目前，水稻和玉米产量相关的基因调控机制仍是研究热点。籽粒大小、粒重与粒形是决定水稻与玉米作物产量的重要性状。APETALA2/乙烯响应因子（APETALA2/ethylene response factor）、生长素响应因子（auxin response factors）以及MADS盒基因家族（MADS）的多数成员，已被证实参与水稻和玉米的产量相关性状调控。解析与产量性状相关的分子调控机制，可为作物产量改良提供理论支撑。随着测序技术的发展，遗传调控网络分析可为基因家族研究提供全新视角。本研究针对上述三类基因家族的成员，解析其进化关系与遗传调控网络，以此预测水稻和玉米中可能参与产量相关性状调控的候选基因。本研究结果可为未来分子生物学相关研究提供理论与应用指导，同时可为培育高产水稻和玉米新品种提供有益参考。
