“…Sugarcane (Scacharum spp. interspecific hybrids) is a major sugar and bioenergy crop worldwide (Li and Yang, 2015;Bordonal et al, 2018;Parsaee et al, 2019). The production of sugarcane requires a large practice of fertilizers, especially nitrogen (N).…”

Plant endophytic bacteria have many vital roles in plant growth promotion (PGP), such as nitrogen (N) fixation and resistance to biotic and abiotic stresses. In this study, the seedlings of sugarcane varieties B8 (requires a low concentration of nitrogen for growth) and GT11 (requires a high concentration of nitrogen for growth) were inoculated with endophytic diazotroph Enterobacter roggenkampii ED5, which exhibits multiple PGP traits, isolated from sugarcane roots. The results showed that the inoculation with E. roggenkampii ED5 promoted the growth of plant significantly in both sugarcane varieties. 15N detection at 60 days post-inoculation proved that the inoculation with strain ED5 increased the total nitrogen concentration in the leaf and root than control in both sugarcane varieties, which was higher in B8. Biochemical parameters and phytohormones in leaf were analyzed at 30 and 60 days after the inoculation. The results showed that the inoculation with E. roggenkampii ED5 improved the activities of superoxide dismutase (SOD), catalase (CAT), NADH-glutamate dehydrogenase (NADH-GDH), glutamine synthetase (GS), and endo-β-1,4-glucanase, and the contents of proline and indole acetic acid (IAA) in leaf, and it was generally more significant in B8 than in GT11. Tandem Mass Tags (TMT) labeling and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to perform comparative proteomic analysis in the sugarcane leaves at 30 days after inoculation with strain ED5. A total of 27,508 proteins were detected, and 378 differentially expressed proteins (DEPs) were found in the treated sugarcane variety B8 (BE) as compared to control (BC), of which 244 were upregulated and 134 were downregulated. In contrast, a total of 177 DEPs were identified in the treated sugarcane variety GT11 (GE) as compared to control (GC), of which 103 were upregulated and 74 were downregulated. The DEPs were associated with nitrogen metabolism, photosynthesis, starch, sucrose metabolism, response to oxidative stress, hydrolase activity, oxidative phosphorylation, glutathione metabolism, phenylpropanoid metabolic process, and response to stresses in Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) database. To the best of our knowledge, this is the first proteomic approach to investigate the molecular basis of the interaction between N-fixing endophytic strain E. roggenkampii ED5 and sugarcane.

“…The nonresponse to N fertilization using blends of CRU and U and just U was also observed in maize in Rhodic Haplustox sites (SCHONINGER et al, 2018;GARCIA et al, 2018), which also has a clayey texture, and in other crops (BOSCHIERO et al, 2020;GARCIA et al, 2020a) in Brazilian conditions.…”

“…Moreover, in our study, the control treatment provided similar conditions for better common bean growth and yield. Nonresponse to N-fertilizer application were also observed in maize production at Rhodic Haplustox and Rhodic Eutrustox sites using blends of PSCU + U and only U (GARCIA et al, 2018;SCHONINGER et al, 2018) and in sugarcane in a Typic Hapludox soil (BOSCHIERO et al, 2020).…”

“…It would be of interest in future studies to evaluate the dynamics of blends of CRU + U and other enhanced efficiency fertilizers using 15 N in sandy loam soil. This soil is normally more responsive for N fertilizer application in maize than clayey soil(GARCIA et al, 2020; U and 30% PSCU + 70% U), at a rate of 180 kg N ha −1 , applied incorporated at sowing, broadcast on the soil surface at sowing, and split (30% incorporated at sowing and 70% sidedressing at V4) can ensure N throughout the maize growth cycle in Brazilian condition. PSCU from U (NUR); and yield (GY).…”
