Fecha de publicación: 02/01/2025 Fuente: WIPO "tomato" The present invention provides a Pararhizobium strain selected from: (a) a strain deposited in the Spanish Type Culture Collection (CECT) with the accession number CECT30825; (b) a strain deposited in the Spanish Type Culture Collection (CECT) with the accession number CECT30826; or (c) a mutant thereof, wherein the mutant: (i) is obtained from CECT30825 or CECT30826 strain, and (ii) retains one or more of the following properties: (ii.1) induction of plant tolerance to chilling temperature; (ii.2) induction of plant tolerance to freezing temperature; (ii.3) induction of plant growth; (ii.4) increased plant yield; and (ii.5) induction of plant tolerance to water deprivation and/or drought. The invention further provides compositions, uses and methods based on the strains of the invention. Advantageously the strains of the invention are of broad-spectrum, providing an effective protective effect in several abiotic stresses, such as low temperatures, water deprivation and/or drought and saline environment.
