Objectives Seeds host microbes that function in plant growth and phytopathogen resistance. The aim of the work was to investigate total bacterial community in malting barley seeds and whether their bacterial seed endophytes have dual functional roles in plant growth-promotion and inhibition of Fusarium graminearum, the causative agent of Fusarium head blight (FHB) in barley. We used culture dependent and culture independent methods. Results Phylogenetic classification of seed endophytic bacteria based on sequencing data identified B. subtilis, B. licheniformis and B. pumilis as predominant subgroups. Location driven divergence in bacterial endophytic communities was evident based on a clear separation of the samples from Crookston and other location samples. The bio-primed seeds using one hundred and seventy bacterial isolates showed that 3.5% (6/170) of the bacterial isolates conferred greater than 10% increase in both root length (RL) and shoot length (SL), while 19.4% (33/170) and 26.5% (45/170) showed RL and SL specific growth effects, respectively, relative to controls. Among the six bacterial isolates that increased RL and SL, five (#29, #63, #109, #124 and #126) also significantly inhibit the growth of F. graminearum based on in vitro assays. This study identified novel seed bacterial endophytes that could be further exploited for promoting growth during seedling establishment and as biocontrol for combating the devastating scab disease.

While agricultural crops remain at the forefront of addressing global food demands and malnutrition, depleting resources, fluctuating climatic conditions, and the adverse impact of biotic/abiotic stresses define a major challenge. Plant seeds comprise an important starting material for plant propagation, in vitro generation, and conservation, and are crucial factors in determining the quality and yield of the desired crops. The expanding horizon of precision agriculture suggests that high-quality seeds could promote crop productivity up to 15–20 percent, attributed to emerging biotechnological innovations in seed science and research. In addition, seed science comprises an integral aspect of sustainable development goals (SDGs), and plays a crucial role in Climate Action (SDG 13) and Zero hunger (SDG 2). While synthetic seed technologies highlight prospects in the propagation and conservation of key plant species, seed biopriming to address environmental stresses is innovative in climate-smart agriculture. The article discusses key developments in advanced seed biotechnologies, ranging from nano-enabled seed treatments to the non-coding RNA-mediated determination of seed traits and genetic manipulation of seeds for quality improvement. Research employing multi-omics, bioinformatics, and seed biopharming for the enhanced production of high-value metabolites is opening new avenues in seed biology and biotechnology research.
