Expression

EC Number Organism Comment Expression
1.14.15.21 Zea mays transcript level of ZEP2 of Zea mays increases in developing endosperm within 14 days after pollination and decreases afterwards, transcript level of ZEP1 of Zea mays remains low during developement of endosperm additional information
1.14.15.21 Zea mays transcript levels of ZEP1 and ZEP2 of Zea mays are highest in leaves, lower in roots and unfertilized ovules and lowest in endosperm and plant embryos additional information
1.14.15.21 Zea mays ZEP1 and ZEP2 of Zea mays transcript levels at 20 days after pollination show inverse correlation with seed zeaxanthin levels additional information
