Annotated Information

Gene Symbol

  • Os05g0477600 <=> OsEXP4


Function

  • The researchers generated transgenic rice plants that express sense and antisense constructs of the expansin gene OsEXP4.


Expression

  • In adult plants with constitutive OsEXP4 expression, 12% of overexpressors were taller and 88% were shorter than the average control plants, and most overexpressors developed at least two additional leaves. Antisense plants were shorter and flowered earlier than the average control plants.


Mutant

  • In transgenic plants with inducible OsEXP4 expression, we observed a close correlation between OsEXP4 protein levels and seedling growth. Coleoptile and mesocotyl length increased by up to 31 and 97%, respectively, in overexpressors, whereas in antisense seedlings, they decreased by up to 28 and 43%, respectively.
