Agricultural and Other Biotechnological Applications Resulting from Trophic Plant-Endophyte Interactions

Abstract

Endophytic microbiota plays a role not only in supplying plants with the basic nutrients indispensable for their growth, but also helps them in the mechanisms of adaptation to various environmental stresses (i.e., salinity, drought), which is important in the aspect of crop yields. From the agricultural and biotechnological points of view, the knowledge of endophytes and their roles in increasing crop yields, plant resistance to diseases, and helping to survive environmental stress is extremely desirable. This paper reviews some of the beneficial plant–microbe interactions that might be potentially used in both agriculture (plant growth stimulation effect, adaptation of host organisms in salinity and drought conditions, and support of defense mechanisms in plants), and in biotechnology (bioactive metabolites, application of endophytes for bioremediation and biotransformation processes, and production of biofertilizers and biopreparations). Importantly, relatively recent reports on endophytes from the last 10 years are summarized in this paper.

Climatic Aridity Gradient Modulates the Diversity of the Rhizosphere and Endosphere Bacterial Microbiomes of Opuntia ficus-indica

“…Two rhizobacteria related to the genus Bacillus were isolated from Brazilian cacti, displaying plant growth-promotion abilities under drought conditions ( Kavamura et al, 2013 ). Sphingomonas , Burkholderia , Ralstonia , Bacillus , Rubrobacter , Blastococcus , Streptomyces , Amycolatopsis , Promicromonospora , and Pseudomonas have been recognized as endophytic bacteria ( Kandel et al, 2017 ; Singh and Dubey, 2018 ; Kuźniar et al, 2019 ). Endophytic bacteria and rhizoplane communities in cacti from the desert areas in Mexico have been identified by previous studies, revealing the effect of the association of bacteria, archaea, and fungi on seed germination and survival of cacti in their harsh natural environment ( Puente et al, 2004a , b , 2009a , b ; Fonseca-García et al, 2016 ).…”

Fusarium Head Blight, Mycotoxins and Strategies for Their Reduction

“…To date, many beneficial interactions between the plant and microorganisms have been revealed that can be potentially used in agriculture, among others for enhancing defense mechanisms in plants and for biopreparation production [179]. It is extremely important to characterize endophytes and their role in agriculture, especially in plant disease resistance [179].…”

It is extremely important to characterize endophytes and their role in agriculture, especially in plant disease resistance [179]. Bacterial or fungal endophytes can penetrate plant tissues and develop in them, thereby affecting plant growth, inducing a defensive response against pathogen attack and acting as agents preventing abiotic stress [180].…”

Diversidade, mecanismos de atuação e potencial agrícola de bactérias promotoras de crescimento de plantas, usando milho como cultura exemplo

“…Como esses gêneros são comuns em solos, tem sido sugerido que a comunidade microbiana endofítica constitui uma subpopulação das bactérias rizosféricas (MARQUEZ-SANTACRUZ et al, 2010;SANTOYO et al, 2016). No entanto, como as plantas conseguem selecionar um determinado grupo de endófitos, ainda não está totalmente esclarecido (KHATABI et al, 2019;KUŹNIAR;WŁODARCZYK;WOLIŃSKA, 2019;WHITE et al, 2019).…”
