“…Recently, Feng et al (2017), reported that C. plantarum possessing plant growth-promoting activities, including IAA production, secretion of phosphate solubilizing enzymes and ACC deaminase may enhance the rice's adaptation and growth in polluted soils. On the other hand, EDS did not show any protection effect against SLB.…”

“…C. plantarum possess some plant growth promotional traits, including indole acetic acid (IAA) and siderophore production, secretion of phosphate solubilizing enzymes and 1-aminocyclopropane-1-carboxylate deaminase (ACCD). Moreover, it is able to detoxify and remove chlorpyrifos residues in infested rice plants and grains (Feng et al, 2017). In tissue cultures, C. pusillum stimulated axillary shoot formation in chrysanthemum, gerbera, and hosta (Zawadzka et al, 2013).…”

“…Some Curtobacterium strains have been isolated from wheat, rice, corn, soybean, oats, alfalfa, olive and many other plants. C. plantarum, in particular, is seed transmitted (Dunleavy, 1989;Feng et al, 2017;Samain et al, 2015). The dual functions of C. plantarum in stimulating plant growth and degrading pollutants have been reported (Feng et al, 2017).…”

Keywords:Wheat septoria leaf blotch Paenimyxin Paenibacillus sp. strain B2 Curtobacterium plantarum Flavonoids Salicylic acid Jasmonic acid Reactive oxygen species A B S T R A C T Many of the non-pathogenic endophytic bacteria that reside in plant roots promote plant growth as well as protection against pathogens attack. However, little is known about their mode of action in wheat. We have previously demonstrated the potential of Paenibacillus sp. strain B2 (PB2) to stimulate plant defense mechanisms via its paenimyxin lipo-polypeptide elicitor. Recently, we isolated the Curtobacterium plantarum strain EDS (EDS) from seeds of almost all wheat cultivars. In the present work, the ability of PB2 and EDS to promote wheat growth and protection against Septoria leaf blotch (SLB) was investigated. Results showed that PB2 is a general root external colonizer and cultivar-dependent endophyte. In the endophytic state and only in co-inoculation, it significantly increased the internal root colonization by EDS, resulting in an increase of root and aerial part fresh weights. qPCR analysis showed that, in the endophytic and nonendophytic states, PB2 conferred ≥59% protection against SLB by inducing systemic resistance which is characterized by the over expression of the pr1, lox, Aos, peroxidase, oxo and gst genes. Paenimyxin conferred 76% local protection characterized by the overexpression of the glu, lox, aos, pal, chs, oxo, and gst genes, and 82% systemic protection by chs. It was concluded that PB2 is potentially very interesting in the biocontrol of SLB and, in a mixture with EDS, in the wheat growth promoting. Genes involved in the flavonoid, salicylic acid, jasmonic acid, reactive oxygen species and basal defense pathways seem to play an important role in the resistance against SLB.

“…Chlorpyrifos (Table ), which displays broad‐spectrum insecticidal activity against important arthropod pests, is one of the most widely used organophosphates . However, growing evidence indicates that chlorpyrifos has adverse impacts on humans' genital and nervous systems and hepatic and renal functions as well as causing congenital defects in infants . Although prohibited for use on vegetables in China since 2016, chlorpyrifos is still commonly used on rice crops.…”

BACKGROUND High levels of harmful pesticide residues in rice can cause undesirable side effects and are a source of great concern to consumers. Reduction of pesticide residues to provide rice security has thus became an urgent problem. RESULTS In this study, the effects of commercial and home processing on removal of chlorpyrifos and carbosulfan residues from rice, and the formation of metabolites during processing, were studied. The results showed that 3,5,6‐trichloro‐2‐pyridinol (0.87 mg kg−1) and carbofuran (0.43 mg kg−1) were the predominant components detected in paddy rice. All detected residues were primarily deposited on the rice hull and bran. Washing twice followed by high‐pressure cooking was able to further decrease residues in polished rice with the processing factor value <0.25. Following application of pesticides at the recommended rate and twice the recommended rate, with a preharvest interval of 28 days, changes in residues from harvest to dining table based on efficient processing techniques were investigated. The final residues dropped to below maximum residue levels after washing twice followed by high‐pressure cooking. CONCLUSION This simple cooking process thus reduces the risk of dietary exposure, and it is recommended that it is adopted by all consumers. © 2019 Society of Chemical Industry

BACKGROUND: This study was conducted to analyze the effects of endophytic Bacillus megaterium (BM 18-2) colonization on structure strengthening, microbial community, chemical composition and stabilization properties of Hybrid Pennisetum. RESULTS: The BM 18-2 had successfully colonized in the interior tissues in both leaf and stem of Hybrid Pennisetum. During ensiling, the levels of pH, acetic acid (AA), butyric acid (BA), propionic acid (PA), and the population of yeast and aerobic bacteria were significantly (P > 0.05) lower, while lactic acid bacteria (LAB) and lactic acid (LA) were significantly (P < 0.001) higher with the steps forward of ensiling in with BM 18-2 as compared to without BM 18-2 colonized of Hybrid Pennisetum. During the different ensiling days, at days 3, 6, 15, and 30, the genus Brevundimonas, Klebsiella, Lactococcus, Weissella, Enterobacter, Serratia, etc. population were significantly decreased, while genus Pediococcus acidilactici and Lactobacillus plantarum were significantly influenced in treated groups as compared to control. The genus Lactobacillus and Pediococcus were positively correlated with treatment groups.CONCLUSIONS: It is concluded that the endophytic bacteria strain BM 18-2 significantly promoted growth characteristics and biomass yield before ensiling and after ensiling inoculated with or without Lactobacillus plantarum could improve the distinct changes of the undesirable microbial diversity, chemical composition, and stabilization properties in with BM 18-2 as compared to without BM 18-2 colonized Hybrid Pennisetum.
