IR6 exhibited the most notable agronomic performance, increasing seedling leaf area, fruit production, and fruit size under field conditions and demonstrating antagonistic activity against Fusarium oxysporum, confirming its potential as a biocontrol agent and PGPR.
This study evaluated the antagonistic potential of rhizosphere fungi isolated from the indigenous plant Solanum lasiocarpum Dunal against R. solani under in vitro conditions, the first report describing antagonistic fungi isolated from the rhizosphere of wild S. lasiocarpum as potential biological control agents agains...
The selection of high-performing plant-bacteria partnerships, adapted to local edaphic constraints, provides a promising and eco-friendly strategy for the rehabilitation of degraded ecosystems.
Preliminary evidence is provided of the potential of a Streptomyces levis strain as a PGP bacterium under saline conditions and Seed germination efficiency revealed that the 24 hrs culture of isolate H had a significantly greater effect on rice seed germination than the 48 hrs culture.
Overall, in planta efficacy was highly variable compared to the strong in vitro inhibition, Nevertheless, selected commercial strains show clear potential to mitigate severe disease symptoms under high R. solani pressure.
Findings indicate that the selected halotolerant nitrogen-fixing endophytic bacterial isolates can promote rice seedling growth under saline conditions and have potential for further development as biological fertilizers for rice cultivation on saline soils.
