In 1994, Shandong University decided to upgrade the office to become the current research center. Prof. Xu Xianming was its first director. In order to enhance human rights law studies and showcase the latest developments in human fights research in China, the center launched the well- recognized academic journal Human Rights Research in 1998.展开更多

Here, we report that CCT domain genes play an important role in flowering in maize （Zea mays L.）. Among the 53 CCT family genes we identified in maize, 28 were located in flowering time quantitative trait locus regions and 15 were significantly associated with flowering time, based on candidate-gene association mapping analysis. Furthermore, a CCT gene named ZmCOL3 was shown to be a repressor of flowering. Overexpressing ZmCOL3 delayed flowering time by approximately 4 d, in either long-day or short-day conditions. The absence of one cytosine in the ZmCOL3 3＇UTR and the presence of a 551 bp fragment in the promoter region are likely the causal polymorphisms contributing to the maize adaptation from tropical to temperate regions. We propose a modified model of the maize photoperiod pathway, wherein ZmCOL3 acts as an inhibitor of flowering either by transactivating transcription of ZmCCT, one of the key genes regulating maize flowering, or by interfering with the circadian clock.展开更多
