  "account": "A study explored the effects of antibiotic-induced disruption in plant-associated microbiomes, specifically in tomato plants. Antibiotic exposure negatively impacted the composition of progeny rhizosphere bacterial communities, leading to reduced defense-associated gene expression and heightened vulnerability to Xanthomonas perforans. This intergenerational impact weakened the plants' ability to mount effective immune responses, directly correlating with increased disease severity. Researchers discovered that seed microbiome transfer from healthy donors partially rectified the rhizosphere community composition, mitigated disease severity, and restored defense gene expression for three genes. Overall, the findings revealed that antibiotic exposure-induced microbiome disturbance generates intergenerational effects that influence plant immunity and susceptibility to disease, with seed microbiome transfer serving as a countermeasure across generations.",
  "summary": "Antibiotic-induced disruption of plant-associated microbiomes has the potential to alter host health beyond the directly exposed generation, yet whether the effects of dysbiosis are transmitted through the seed microbiome remains unknown. Here, we investigated the intergenerational impacts of streptomycin-induced dysbiosis in tomato (Solanum lycopersicum), demonstrated that seed microbiome…",
