Auxin producing plant growth promoting bacteria enhance temperature stress tolerance in Chilean common bean landraces.

ABSTRACT: Current climate change challenges, including rising temperatures, reduced water availability, and increased soil salinity, pose severe threats to global agricultural productivity. While plant growth promoting bacteria (PGPB) have been studied for their role in stress mitigation, their application in enhancing heat tolerance in Chilean landraces of common bean (Phaseolus vulgaris L.) remains largely unexplored. This study evaluated the interaction between native PGPB and genetically distinct Chilean common bean landraces, which are part of the Andean gene pool and represent a socio-cultural food heritage. Auxin production and root adhesion capacity were first validated for two native Bacillus strains. Subsequently, their effects on heat-stressed plants were assessed at physiological and bio
