Abstract: The present invention relates to processes for recovering areas degraded by mining by means of soil treatment. In this context, the present invention provides a method for reusing ore concentrate waste, comprising the steps of (i) generating a solid or pasty residue from ore concentration, (ii) enriching the residue with at least two organic binders and a fertilizer to obtain an enriched/improved residue, (iii) depositing the enriched residue on the mined ground to form an enriched subsoil and (iv) depositing a topsoil layer on the enriched subsoil.

Abstract: The disclosure relates to modification of a heat resistant cytoplasmic heat stable 6-phosphogluconate dehydrogenase (6PGDH) enzyme by fusing the cytoplasmic 6PGDH enzyme in frame to a plastid-targeting sequence. This modification allows the import of the cytoplasmic 6PGDH enzyme into plastids of a plant cell. Polynucleotides encoding and expressing the modified cytoplasmic 6PGDH enzymes are provided. The disclosure further provides transgenic plants and seeds containing the disclosed polynucleotides and expressing the modified cytoplasmic 6PGDH enzymes during development. The invention further relates to methods for developing a transgenic plant that has increased heat resistance and yield during heat stress.
