characterization of the isolates Biochemical characterization was carried out using API 20E strips (BioMerieux, Spain) supplemented with additional tests. Since studies by other workers showed that acetoin production (Voges-Proskauer (VP) test), citrate use, gelatin hydrolysis, and sorbitol fermentation were likely to be the most variable biochemical traits among Y. ruckeri isolates, we performed... -

dipeptide (basilysin), acetoin, 2, 3-butandiol, etc. (Lee et al., 2012; Ramarathnam et al., 2007). These can aid in the inhibition of mycelial growth or spore germination in fungal pathogens, induction of resistance, and formation of biofilms to prevent plant diseases. It can be used in farms as an eco-friendly control strategy in organic potato culti- vation. Bacillus strains produce various... Although late blight is an important disease in eco- friendly potato cultivation in Korea, it is highly depen- dent on the use of eco-friendly agricultural materials and the development of biological control technology is low. It is a necessary to develop an effective biocontrol agent to inactivate late blight in the field. AFB2-2 strain is a gram-positive with peritrichous flagella. It can uti- lize 20 types of carbon sources, like L-arabinose, and D- trehalose at 35°C. The optimal growth... -

of BVCs is an important factor for chemigation. Several BVCs such as acetoin (100 g/l), indole (1.9 g/l), and dimethyl disulfide (2.5 g/l) are highly soluble in water. For lipophilic com- pounds, emulsifiable concentrate formulations composed Fig. 3. Uses of biogenic volatiles in plant health applications. Microcapsule and sol-gel formulations of biogenic volatile compounds can be used in a... Plants and microorganisms (microbes) use information from chemicals such as volatile compounds to understand their environments. Proficiency in sensing and responding to these infochemicals increases an organism’s ecological competence and ability to survive in competitive environments, particularly with regard to plant-pathogen interactions. Plants and microbes acquired the ability to sense and respond to biogenic volatiles during their evolutionary history. However, these signals can only be... -

(acetoin). Among them, acetoin was found to be the major compound (Table 4, Supplementary Fig. 1). Discussion One of the biggest ecological challenges facing micro- biologists and plant pathologists in the near future is the development of environmentally friendly alternatives to chemical pesticides for combating crop diseases. The use of beneficial microorganisms is considered as one of the... analysis. Moreover, volatile compounds emitted from strain G341 were found to be able to inhibit mycelial growth of various phytopathogenic fungi. Based on volatile compound profiles of strain G341 obtained through headspace collection and analysis on GC-MS, dimethylsulfoxide, 1-butanol, and 3-hydroxy-2-butanone (acetoin) were identified. Taken together, these results suggest that B. valezensis G341 can be used as a biocontrol agent for various plant diseases caused by phytopathogenic fungi. -

B. pumilus INR7. The effects on plant growth and development may be mediated by volatile organic compounds (VOCs) emitted by bacilli. Previous research discovered that the VOCs 2,3-butanediol and acetoin emitted by B. subtilis GB03 and B. amyloliquefaciens IN937a promoted Arabidopsis plant growth (Ryu et al., 2003). Additional analyses us- ing diverse signaling mutants of Arabidopsis revealed... Certain bacterial species associate with plant roots in soil. The plant growth-promoting rhizobacteria (PGPR) stimulate plant growth and yield in greenhouse and field. Here, we examined whether application of known bacilli PGPR strains stimulated growth and asexual reproduction in the succulent plant Kalanchoe daigremontiana. Four PGPR strains B. amyloliquefaciens IN937a, B. cereus BS107, B. pumilus INR7, and B. subtilis GB03 were applied to young plantlets by soil-drenching, and plant growth... -

et al., 2013), 2,3-butanediol and acetoin (Kloep- per et al., 2004; Farag et al., 2006; Ryu et al., 2004), 3-pen- tanol and 2-butanone (Song and Ryu, 2013), and alcohols and ketones (Li et al., 2010). Previous reports suggest that surfactin is important in the suppression of plant diseases among these elicitors. Enough surfactin was detected in hydro-culturing tomato rhizosphere (Cawoy et al.,... Bacillus subtilis B006 strain effectively suppresses the cucumber fusarium wilt caused by Fusarium oxysporum f. sp. cucumerinum (Foc). The population dynamics of Foc, strain B006 and its surfactin over-producing mutant B841 and surfactin-deficient mutant B1020, in the rhizosphere were determined under greenhouse conditions to elucidate the importance of the lipopeptides excreted by these strains in suppressing Foc. Results showed that B. subtilis strain B006 effectively suppressed the disease in... -

tomato (Audenaert et al., 2002). During fermentation of glucose, S. plymuthica, like many other bacterial species, is able to switch from producing mixed acids to producing natural chemicals such as acetoin and 2,3-butanediol to avoid the lethal acidifi- cation of its environment. N-(3-oxo-hexanoyl)-L-homoserine lactone (OHHL) plays an important role in acetoin and 2,3- butanediol production (Moo... Numerous root-associated bacteria (rhizobacteria) are known to elicit induced systemic resistance (ISR) in plants. Bacterial cell-density-dependent quorum sensing (QS) is thought to be important for ISR. Here, we investigated the role of QS in the ISR elicited by the rhizobacterium, Serratia marcescens strain 90?166, in tobacco. Since S. marcescens 90?166 produces at least three QS signals, QS-mediated ISR in strain 90?166 has been difficult to understand. Therefore, we investigated the ISR...
