Histone H3 lysine 27 tri-methylation and lysine 9 di-methylation are independent repressive chromatin modifications in Arabidopsis thaliana. H3K27me3 is established and maintained by Polycomb repressive complexes whereas H3K9me2 is catalyzed by SUVH hist
Although most research has been undertaken in mammals, genes encoding core EJC components have been found in plants [22], suggesting that there is structural and functional conservation in the EJC complex among plant and mammalian. However, only limited evidence has been reported on the physiological...
Multiple pollinators on the same host plant indicate that plant and pollinator speciation are not perfectly linked. Where speciation occurs in the pollinator but not the plant, a plant will become host to co-pollinating sister species [27,32]. Pollinators might speciate for a variety of reasons...
