Technology background
The phosphate is slightly mobile nutrient and has limited availability for the plants in terms of absorption. Thus, the ability of plants to meet the need of this nutrient is directly correlated with its ability to exploit the soil. Phosphate deficiency if there is a change in root system architecture, making a key adaptive mechanism for this type of stress. The phosphate concentrate in the upper soil, where there is greater presence of organic matter. Therefore, plants more adapted to the condition of low concentration of phosphate in the soil invested in developing more shallow roots
Technology description
This invention proposes a new strategy to make the most tolerant plants to phosphate deprivation. ASR genes are involved in the further development of new roots (lateral and adventitious) plants in phosphate deprivation condition, to allow a greater phosphate uptake by roots.
Problem Fixed
plant development in phosphate deprivation condition.
Advantages
-Sustainability: The phosphate is a non-renewable nutrient and irreplaceable. It is possible that the phosphate reserves are depleted from 60 and 100 years. I turn to 80% the extracted phosphate is used in agriculture. Only 30% phosphate applied to the soil is absorbed by plants, therefore, a plant that is able to use the nutrients in a more efficient has great relevance in the present and future scenarios of agriculture.
-economy: With decreasing application phosphate, Nutrient applied in large quantities in all cultures, the cost to the producer and consequently decrease the cost of food for consumers.
-waste reduction: Since the absorption of this nutrient is low in plants, the portion not absorbed and does contaminated water proliferation of algae, harmful to human health.
Applications
Not present, to obtain a more efficient plant in phosphate uptake, It is possible to apply a smaller amount of nutrient in the soil, maintaining productivity. no future, considering an extreme situation, If you run out of phosphate reserves, It may be possible to grow plants without even extra application of nutrient. One can also think of a strategy Biofortification. Since the plant absorbs more phosphate, You can be studied how this nutrient is translocated to the edible parts of plants, thus providing a more nutritious food.
