Niels Sandal

Title: Niels Sandal: Innovator in Plant Nodulation

Introduction

Niels Sandal is a prominent inventor based in Tilst, Denmark. He has made significant contributions to the field of plant biology, particularly in the area of nitrogen fixation in legumes. His innovative work has the potential to revolutionize agricultural practices by reducing the dependence on nitrogen fertilizers.

Latest Patents

Niels Sandal holds a patent for his invention titled "Spontaneous nodulation in plants." This patent describes the formation of nitrogen-fixing root nodules in legumes, which is induced by the perception of lipochitin-oligosaccharide signal molecules secreted by compatible bacteria. The invention provides a spontaneous nodule formation (snf1-5g) mutant, which allows for nodule development in the absence of bacteria and/or exogenous rhizobial signals. Additionally, it includes an isolated DNA sequence encoding a mutant chimeric Ca/calmodulin-dependent protein kinase, which results in a 'gain of function' phenotype of spontaneous nodule formation. This gene has the potential to confer a spontaneous nodule formation phenotype to plants with a nodulation-deficient genetic background, thereby enhancing nitrogen-fixing capabilities in non-nodulating plants.

Career Highlights

Niels Sandal is affiliated with Aarhus Universitet, where he conducts research and develops innovative solutions for agricultural challenges. His work focuses on enhancing the efficiency of nitrogen fixation in crops, which is crucial for sustainable agriculture.
