Application

EC Number Application Comment Organism
2.7.7.27 agriculture expression of maize Sh2r6hs transgene, a modified maize Sh2 cDNA coding sequence with alterations conferring reduced sensitivity to phosphate inhibition and greater heat stability, in Triticum aestivum results in increased photosynthetic rates under high light but not low light conditions, peaking at 7 days after flowering. Transgenic plants show increases in levels of fructose, glucose, and sucrose in flag leaves at 7 and 14 days after flowering Zea mays
