Isolation and in silico analysis of phosphoenolpyruvate carboxylase gene and effects of indoleacetic acid and kinetin on sucrose production of sugarcane (Saccharum officinarum L.)

Sugar is the most important food constituent in almost all countries around the world. The sugarcane plant is the most important source of sugar production in which 80% of the sugar production worldwide is derived from. This study aims to isolate, identify and characterize the phosphoenolpyruvate ca...
