Bioprospecting of elite plant growth-promoting bacteria for the maize crop

Abstract: The use of plant growth-promoting bacteria (PGPB), which aims to replace chemical fertilizers and biological control, is a goal for achieving agriculture sustainability. In this scenario, our goal was to identify and evaluate the potential of bacteria isolated from maize roots to promote plant growth and be used as inoculants. We evaluated 173 bacterial strains isolated from the maize (Zea mays L.) rhizosphere for the properties of their PGPB in vitro. Twelve strains were positive for siderophores, indole acet… Show more

“…Several studies indicate that the efficiency of associative diazotrophs depends on plant genotype and age, which generate various responses that must be previously tested to certify the inoculation technique. The strain/species also modulates the communication between the pre-existing microbial community and the strain introduced as an inoculant (Hungria et al, 2016;Ikeda et al, 2020;Reis et al, 2018).…”

“…Diversas bactérias da rizosfera já foram identificadas com efeitos antagônicos a fungos e nematoides (STURZ; NOWAK, 2000;TIAN;YANG;ZHANG, 2007;MACHADO et al, 2012), produzindo antibióticos, toxinas e enzimas, interferindo no processo de reconhecimento planta-hospedeiro, induzindo resistência ou proporcionando o desenvolvimento da planta (SIDDIQUI; SHAUKAT, 2002;BAGHEL;AKHTAR, 2007;STIRLING, 2017). Algumas das espécies mais frequentemente citadas são de Bacillus, e pelo menos parte destas forma endósporos e apresenta uma multiplicidade de mecanismos antagônicos (DOMENECH et al, 2006; GROVER; NAIN; SAXENA, 2009; KAKAR et al, 2018; ALOO; O potencial para FBN, isoladamente ou associado a outros mecanismos, foi identificado e quantificado em diferentes espécies vegetais como Dodoneae viscosa L. (AFZAL et al, 2017), milho (CARVALHO et al, 2017;GARCIA et al, 2017;MARAG;SUMAN, 2018;IKEDA et al, 2020), arroz (CHAUDHARY et al, 2012BANIK;MUKHOPADHAYA;DANGAR, 2016;BEUTLER et al, 2016;MAHMUD et al, 2020) e cana- de-açúcar (TAULÉ et al, 2012;RODRIGUES et al, 2018;MAHMUD et al, 2020).…”

“…Diversos autores obtiveram isolados com potencial in vitro de produção de AIA, sendo eles provenientes de diferentes espécies vegetais como Dodoneae viscosa (AFZAL et al, 2019), Agrostis capillaris L. (GROBELAK; NAPORA; KACPRZAK, 2015), Tripogon spicatus (FERNANDES-JÚNIOR et al, 2015), tomate (KHAN et al, 2016), capim-pangolão (MENDONÇA et al, 2019), milho (BATISTA et al, 2018;MARAG;SUMAN, 2018;JOCHUM et al, 2019;IKEDA et al, 2020), trigo (SALA et al, 2008CHERIF-SILINI et al, 2016;EMAMI et al, 2019) e cana-de-açúcar (SILVA et al, 2012). A longa lista de exemplos indica como esse relacionamento entre plantas e bactérias endofíticas deve ser comum na natureza.…”
