Soil salinity is a growing constraint to agricultural productivity, particularly in arid and high-altitude regions such as the Bolivian Altiplano, where environmental conditions promote the accumulation of salts and limit crop growth. This project addresses the need for sustainable, biologically based solutions to improve plant resilience under saline stress. The overall objective is to design a synthetic rhizosphere consortium capable of enhancing crop productivity by integrating complementary microbial functions.
The central hypothesis is that a functionally coordinated microbial consortium can improve plant tolerance to salinity by simultaneously promoting osmoprotection, maintaining nitrogen fixation, and stabilizing soil structure. To test this, the project focuses on three key organisms: Pseudomonas fluorescens, Azospirillum brasilense, and Bacillus subtilis, each engineered or selected to perform a specific role within the rhizosphere.
The specific aims include: (1) designing salt-responsive genetic circuits for osmoprotectant production, (2) ensuring stable nitrogen fixation under saline conditions, and (3) enhancing biofilm formation for improved soil aggregation. This project will be conducted primarily in silico using Benchling to design and organize genetic constructs, simulate functional pathways, and document workflows. The expected outcome is a modular and scalable microbial system that can be translated into future experimental validation and ultimately applied to improve agricultural sustainability in saline environments.
