Abstract
Millets are nutritionally rich crops, constituting an important part of the diverse food crops grown and consumed in most states of India and its surrounding regions. The different types of millets have different nutritional properties, and the nutrient profile varies depending on the soil conditions they are grown under. The millet rhizosphere harbours diverse and beneficial microbial communities playing myriad roles. The important roles of the microbes include supporting plant growth, pest and pathogen resistance, acclimatising the plants to harsh climatic conditions and anthropogenic pressures. The millet rhizobiome is unique since it may confer to drought resistance, participate in biogeochemical cycles of nitrogen, carbon, phosphorus, potassium, sulphur, etc., allowing the plants to adapt well in arid and nutrient-deficient soils. Furthermore, microbial diversity, abundance, and their multiple functions are essential for reductions in greenhouse gases (GHG) from agricultural soils, water retention, decomposition activities, increasing soil organic matter, weathering, etc. Advancing interdisciplinary tools for deciphering microbial communities including high throughput metagenome sequencing, advanced computational tools, etc. are increasingly being used to decipher and elucidate the microbial communities in the rhizosphere. Metagenomics has helped unravel many bacterial communities that are dominant in the millet rhizosphere, paving way for future characterization of their potential multifunctionalities. In this chapter, we have given an account of the metagenomics performed for different millets and the multifunctionalities associated with these future climate-adaptable crops.
