Research Abstract |
Deficiency of phosphorus which is one of the three major nutrients, is a limiting factor of agronomical production over the world. I have made progress in genetic analysis of two kinds of agronomical traits in rice, which can be useful for solving the problem. One trait is "Root Elongation under Phosphorus deficiency". Its contribution to P-deficiency tolerance was evaluated and fine-mapping of the gene was conducted. The other trait is "Acid Phosphatase" which can be useful for P recycling from old leaf blade. Its effect on P content in new developing leaf and the genetic factor were studied.
