RECOMBINANT DNA VECTOR, METHOD FOR PRODUCING PLANTS THAT ARE RESISTANT TO ENVIRONMENTAL STRESSES, AND USES THEREOF

摘要

Plants are influenced by a large number of biotic and abiotic environmental factors, recurrent abiotic stresses being the most serious and affecting all organic functions of the plants, leading to reduced growth and productivity. In this context, identifying and understanding abiotic resistance mechanisms are crucial for developing new drought-resistant cultivars. The present invention thus provides a method for producing plants containing in their cells a sugarcane nucleotide sequence, overexpression of this gene increasing the plant's resistance to abiotic stresses. More generally, a polynucleotide is described that encodes sugarcane protein and is expressed by a promoter and a terminator that are operational in plants. This gene has been discovered to impart resistance to various abiotic stresses.
