Analysis of genes contributing to plant-beneficial functions in plant growth-promoting rhizobacteria and related Proteobacteria

Abstract: The positive effects of root-colonizing bacteria cooperating with plants lead to improved growth and/or health of their eukaryotic hosts. Some of these Plant Growth-Promoting Rhizobacteria (PGPR) display several plant-beneficial properties, suggesting that the accumulation of the corresponding genes could have been selected in these bacteria. Here, this issue was targeted using 23 genes contributing directly or indirectly to established PGPR effects, based on genome sequence analysis of 304 contrasted Alpha- B… Show more

“…Recently, based on genome sequences of 304 Proteobacteria, Bruto et al (2014) analyzed the distribution of 23 genes that may contribute to the ability of these bacteria to promote plant growth. These authors suggest that gene transfers, predominantly ancient, resulted in characteristic gene combinations according to taxonomic subgroups of PGPB strains.…”

“…A complete description of the phylogeny and evolution of the genes encoding acdS and its major regulatory gene, acdR, has been recently elaborated (Bruto et al, 2014;Nascimento et al, 2014). Information regarding acdS/acdR sequences must be considered together with the habitat, the origin, and the enzymatic activity of completely sequenced bacterial strains to obtain a comprehensive view.…”

“…O fluxo de elétrons através da nitrogenase no processo de FBN envolve ainda a redução da Fe-proteína por proteínas doadoras de elétrons (ferredoxinas e/ou flavodoxinas) (Haaker e Klugkist 1987). Assim, além dos genes nif, o processo de FBN requer genes envolvidos na ativação da Fe-proteína, na biossíntese do cofator ferro-molibdênio, na doação de elétrons e genes regulatórios da síntese e função da enzima (Bruto et al 2014). No genoma de RZ2MS9, não foi detectado nenhum gene nif, porém o genoma apresenta genes responsáveis pela codificação de proteínas envolvidas na biossíntese e transporte do cofator molibdênio (moa, mod e moe), na biossíntese de ferredoxinas e flavodoxinas (fer e fld) e na regulação do processo de fixação biológica de nitrogênio (fix).…”

“…Ipdc pertence a uma família de enzimas que exibe alta conservação, visto que a substituição de apenas alguns aminoácidos no sítio ativo pode deslocar a afinidade primária para outro substrato (Grady et al 2016), ela está envolvida em uma via biossintética do fitormônio ácido indol acético, e será discutida em detalhes no Capítulo 4. Estudos de homologia em sequências dessa proteína tem demonstrado identidade de mais de 96% entre linhagens, inclusive aquelas com diferentes ecologias (Bruto et al 2014), assim como a identidade (97,3%) observada na análise comparativa entre as linhagens do Clado RZ2MS9 para essa proteína. …”
