decades were evidenced by a growing interest in the investigations aimed at origins,
interactions of endophytes, as a new source of asymptomatic establishment in the
plants opening horizon of studies in agrobiology. These microorganisms are not
limited to bacteria and actinobacteria, even some important groups like fungi are
also involved in the production of bioactive compounds. Their beneficial association of mycorrhizal fungi to boost plant growth and productivity enhancement was
involved in the book venture. For all these purposes, minimal nutrient uptake and
balanced accumulation modulate is an utmost requirement which only met-out by
the exploitation of different endophytes genera in crop production (Jayakumar et al.
2019; Guo et al. 2019). Similar to biofertilizers, the commercialization of endophytic
organisms as bioinoculants is a reality of the hour and covered in many chapters of
the book, this, however, explores the use of the more efficient organisms concerning
their potential in crop productivity enhancement via a suitable and sustainable way.
This involves resistance mechanisms to the major abiotic and biotic stresses which
often create confidence among the farmers (Firrincieli et al. 2020). But to isolate
such multifarious endophytes, we have to go back into the biblical era to the present
era. For example, dung as a novel source of microbes, if amended with its inhabited
bacteria, acted as a catalyst for augmenting the crop productivity and soil fertility for
sustainable nutrient management practices. Sometimes nutrient deprivation specifically iron may be proved most beneficiary in the mechanism of plant disease control.
This also includes a couple of chapters in the last of the book.
On the other hand, endophytes also provide a firm substitute for lack of phosphorus, zinc, potassium, nitrogen, etc., and besides their application, support soil
biology (Arya et al. 2020). Considering such viable strategies, the endophytic
microorganisms are now established as good as pure chemical fertilizer for boosting
crop yield.
Harnessing beneficial endophytic microorganisms for delivering macro and
micronutrients may provide new trends and prospects to agroeconomy if it meets out
the requirements to apply as a formulation product for a wider application similar
to the free-living plant growth-promoting rhizobacteria (Etesami and Maheshwari
2018). This complex association is evident in the information provided in this volume.
Almost all plants inhabit some endophytic microorganisms and only a few have been
studied so far—the diverse plants of different habitats such as temperate, tropical
zones.
In the last, this is to say that characterization of endophytes using advanced
tools can help in finding more bacterial inoculants. Modern tools and techniques of
including metagenomics, proteosomes, metabolome, transcriptomes, etc., may help
in defining characteristics of endophytes for better improvement of crop productivity.
Scientists may reap benefits of day to day increasing publications on endophytes.
