Supporting evidence — 5 representative gaps

• Physiological Mechanisms of Plant Growth-Promoting Rhizobacteria in Enhancing Abiotic Stress Tolerance of Vegetable Crops: A Review (2026) · Plants · cited 9× · doi

  The paper identifies the gap in the understanding of the mechanisms by which PGPR enhance abiotic stress tolerance of vegetable crops. The paper also identifies the gap in the application of PGPR in large-scale field conditions. The transition of PGPR from laboratory results to reliable field application faces significant hurdles.

• Biopriming with plant growth-promoting bacteria enhances germination and stress tolerance of Pinus nigra seeds under drought and salinity stress (2026) · Frontiers in Forests and Global Change · cited 1× · doi

  The effectiveness of biopriming in Pinus nigra remains poorly understood. There is a need to evaluate the effects of seed biopriming with PGPB on the germination performance of Pinus nigra under simulated drought and salinity stress.

• Isolation and Characterization of Stress-Tolerant Rhizospheric Plant Growth-Promoting (PGPR) from Rhizospheric soil of Chickpea (2026) · Zenodo (CERN European Organization for Nuclear Research) · doi

  There is a need to identify stress-tolerant PGPR from the rhizospheric soil of chickpeas. The study aims to address the gap in knowledge on the potential of PGPR in promoting plant growth and stress tolerance.

  Further studies are needed to evaluate the effects of biopriming on plant establishment and growth under field conditions. The use of biopriming in combination with other stress-mitigating strategies should be explored. The potential of biopriming to enhance the tolerance of other plant species to abiotic stress should be investigated.

• Soil and genotype-driven resource allocation trade-offs shape root exudation across crop species (2026) · Plant and Soil · doi

  While increased exudation under abiotic stresses has been frequently linked to enhanced plant resilience, crop- and genotype- and soil-specific exudation patterns under non-stress conditions remain poorly understood.
