“…First, the genus Burkholderia are known to be present with high abundance in soil environments (Coenye & Vandamme 2003;Stoyanova et al 2007). In general, the study associated with plant-Burkholderia interaction is well understood (Sessitsch et al 2005;Ibal et al 2018). However, in recent study, strains in the stinkbug-associated beneficial and environmental Burkholderia group (SBE clade) are particularly known to form a symbiotic relationship with R. pedestris (Kikuchi et al 2012), and a field survey in South Korea indicates that the SBE Burkholderia are fairly prevalent in soil (Kim, unpublished data).…”

Many arthropods including insects have symbiotic relationships with diverse microorganisms that can confer fitness benefits to their hosts. Riptortus pedestris is a serious pest on leguminous crops in East Asia including South Korea and Japan. Recently, has been reported that R. pedestris form symbiosis with Gram‐negative bacteria in the genus Burkholderia where they acquire symbionts from soil environments without vertical transmission from each generation. In order to address how R. pedestris acquire their symbiont from environment, we hypothesized that R. pedestris would detect and exhibit preference toward the Burkholderia symbionts. In this study, we conducted a series of dual‐choice experiments and Y‐tube olfactometer experiments to monitor and evaluate behavioral responses by 2nd instar R. pedestris toward the Burkholderia treatment and untreated control under various experimental settings in the laboratory. In dual‐choice experiments, there was no significant preference by R. pedestris to the Burkholderia treatment compared with untreated control. Also, no significant difference was detected in the first choice frequency, visiting frequency, and residence time of the insects between the two treatments. Likewise, there was no detectable preference by R. pedestris to microbial odors from the symbionts in Y‐tube experiments. Therefore, our results indicate that there was no evidence supporting that 2nd instar R. pedestris exhibit preference to the Burkholderia symbiont in the laboratory conditions of this study. Further studies are required to evaluate behavioral responses of later immature stages (i.e., 3rd and 4th instar) to the symbionts and provide choice settings at larger semi‐field arenas.

“…Production of stress hormone, ethylene in plants causes physiological damage such as leaf chlorosis, wilting, necrosis, and reduced biomass [51]. However, it is possible to protect plants from the effects of stress hormone, ethylene by employing different strategies such as the inhibition of ACC synthase mRNA accumulation (through salicylic acid); the use of polyamines (spermidine, putrescine), which has also revealed anti-senescence properties; and the application of ACC-deaminase-producing bacteria under different stress conditions [23,52,53]. A recent report [54] showed the effect of abiotic stress on ACS8 and ethylene production.…”

Profiling of ACC synthase gene (ACS11) expression in Arabidopsis induced by abiotic stresses

Abiotic stress induce the production of 1-aminocyclopropane-1-carboxylate (ACC), the precursor of ethylene by activating the enzyme ACC synthase. There are twelve ACC synthase genes reported in the genome of Arabidopsis, and the ACC synthase 11 (ACS11) gene encodes a polypeptide that is functional; however, its involvement in ethylene biosynthesis in response to abiotic stresses remains unclear. We evaluated the effects of higher ACC accumulation on A. thaliana seedlings in response to abiotic stressors such as flooding, salinity, cold, and drought. Transgenic plants were generated with ACS11 (ACS11-OX), and they demonstrated that overexpression of ACS11 reduces both root and shoot length observed in seedlings. RT-PCR analysis revealed that abiotic stressors induce the expression of the wild type ACS11 gene. Histochemical staining revealed that GUS activity followed the same time course as induction of wild type ACS11 gene expression, increased ACC levels, and production of stress hormone, ethylene. One finding showed that although induction of wild type ACS11 gene occurs under drought stress, GUS activity was highest at 6 h of drought stress and decreased to levels similar to control seedlings at 12 and 24 h. Thus, Wild type ACS11 expression is involved in ACC production, and abiotic stressors induce the expression of ACS11 gene. Moreover, ACC increases in response to abiotic stress lead to the production of ethylene. All of the data presented here suggest that the overexpression of ACS11 paves the way for the production of stress hormone, ethylene, which adversely affected the growth and development of the plant. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

There are many different kinds of PGPR, among which Pseudomonas and Bacillus species have often employed as bacterial components of natural fertilizer [4,5].

Wheat is one of the most important grains. Its consumption is increasing globally. Many countries are making efforts to increase the extent of wheat harvest. It is known that plant growth promoting rhizobacteria (PGPRs) have beneficial effects on various plants. Two PGPRs including Paenibacillus pabuli strain P7S (PP7S) and Pseudomonas nitroreducens strain IHB (PnIHB) were employed to investigate effects of PGPRs on early growth of three wheat cultivars (Koso, Seakumkang, and Jokyung). While PP7S had adverse effects on Seakumkang and Jokyung, PP7S had positive effects on Koso except root length compared to control group having no treatment of PP7S. However, all treatments with PnIHB had adverse effects on germination rate, root/shoot lengths, vigor index, and dry root/ shoot weights of all three wheat cultivars. These positive effects with PP7S on Koso might be related to the earlier emergence of wheat seed above soil which is known to be an indicator of increased yield. Results of the present study suggest that if proper PGPR strains are selected, they could have positive effects on early growth rate of a wheat cultivar.
