Bacterial endophytes in barley grains showed responses to Fusarium head blight (FHB), barley genotype, plant growth stage and testing year, suggesting their potential to predict FHB conditions through microbiome interactions. ABSTRACT Endophytes are organisms that maintain an intimate relationship with the plant host as they are adapted to the niche of

Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude
