As an important macro element for all living cells, phosphorus is essential in agricultural production systems as well and is required in large quantities by elite varieties of crops to maintain yields. Approximately 70% of worldwide cultivated land suffers from phosphorous deficiency, and it has recently been estimated that worldwide phosphorous resources will be shattered by the end of this century thus increasing the demand for crops to be more efficient in their P usage. A greater understanding of how plants can maintain yield with lower phosphorous availability is highly desirable to both breeders and farmers, therefore, significant to develop …
