In information security field underlying cryptography, random sequences, which are the base of system security, play a very important role. Random sequences with high security are often needed in cryptography field. From the view of security, real random sequences should be completely unpredictable and reliable. In many circumstances, a random number not only need to be random, but also need to...
The control of flowering is central to reproductive success in plants, and has a major impact on grain yield in crop species. The global importance of temperate cereal crops such as wheat and barley has meant emphasis has long been placed on understanding the genetics of flowering in order to enhance yield. Leads gained from the dissection of the molecular genetics of model species have combine...
Polycomb group protein (PcG)-mediated gene silencing is emerging as an essential developmental regulatory mechanism in eukaryotic organisms. PcGs inactivate or maintain the silenced state of their target chromatin by forming complexes, including Polycomb Repressive Complex 1 (PRC1) and 2 (PRC2). Three PRC2 complexes have been identified and characterized in Arabidopsis; of these, the EMF and VR...
Vernalization is the acceleration of flowering by prolonged cold that aligns the onset of reproductive development with spring conditions. A key step of vernalization in Arabidopsis is the epigenetic silencing of FLOWERING LOCUS C (FLC), which encodes a repressor of flowering. The vernalization-induced epigenetic silencing of FLC is associated with histone deacetylation and H3K27me2 and H3K9me2...
