Abstract
As an alternative to harmful chemical fertilizers and toward fulfilling Sustainable Development Goals (SDGs) of the United Nations, growth promoting rhizobacterial bioinoculants, emerged as potential players. These act in multifunctional ways, including seed colonization, seed germination, stress tolerance and many more, leading to proper growth and development of plants. Biopriming seeds with these beneficial multi-trait microbes is an effective way to introduce them in the soil, and this is an example of bottom-up approach of rhizosphere engineering. Using such sustainable approach is promising and, to investigate and analyze, their research trends are of prime importance. Thus, data were retrieved using Lens and Scopus databases and used for patent landscaping and citation network analysis, respectively. For patent landscaping, documents obtained using customized keyword search were broadly from the past 35 years (1987–2022) and yielded 114 patents which were manually curated in title, abstract and claims (TAC). From the year 2000, interest in this area was observed which further gained momentum from the year 2008, and a maximum peak was observed in the year 2021. Patent profile (filed, granted and published) showed an upward trend during this tenure (1987–2022). In this research article, we aim to provide an overview of current research in this field, identify research hotspots, project future development prospects and make recommendations for further research. Patent landscaping and citation network analysis were used to analyze the recent trends in biopriming approaches using microbial bioinoculants for the first time to identify progress and hotspots in the field of seed priming with PGPRs.
