Research Abstract |
Two B3 domain repressors, HSI2 and HSL1, are essential for the transition of dormant embryonic meristem into vegetative meristem. HSI2 directly represses the expression of seed maturation genes containing RY motif and it is essential for the chromatin histone modification with the H3K27me3 inactive mark. Plants with LUC reporter genes were used for the real-time live monitoring of the repression of seed maturation genes during the early stage of germination and for the large scale screening of mutants defective in the repression of seed maturation gene after germination.
