Expression Patterns of Four Monocots Endosperm Promoters in Arabidopsis thaliana

【摘要】：正As a place to store the carbohydrates,lipids,and proteins that used as source of energy,carbon,and nitrogen during the germinating seedlings,the endosperm of monocotyledonous seeds is an additional attractive system for developmental biology studies.Many dicot species have the most common type of endosperm development compared with that of the monocots,although the molecular mechanism of endosperm development is little known.To investigate the temporal and spatial regulation directed by the monocotyledonous endosperm -specific promoters in dicot,the four promoters activity were investigated in transgenic Arabidopsis
