2.7.7.27 additional information
-
 Zea mays
2.7.7.27 additional information the Sh2r6hs transgene increases enzyme activity in developing endosperm by 2.7fold in presence of phosphate and this increased enzyme activity influences the plant phenotype: both seed weight per plant and total plant biomass Oryza sativa

Cloned(Commentary)

EC Number Cloned (Comment) Organism
2.7.7.27 the two transgenic lines RS1 and RS10 show strong expression of the Sh2r6hs transgene and increase seed weigth per plant 28 and 22%, respectively, whereas the lower expressers RS4, RS20 and RS22 average only an 8% increase in seed weigt per plant Oryza sativa
