Lysobacter enzymogenes is less-studied, but emerging as a powerful biocontrol bacterium producing multiple antimicrobial weapons including lytic enzymes, toxins, secondary metabolites and protein secretion *** loss of surface-attached flagellum, production of heat-stable antifungal factor(HSAF, also named as Ningrongmycin) as a novel antifungal antibiotic, and the use of the type Ⅳ secretion system(T4SS) rather than the common type Ⅵ secretion system(T6SS) to kill competitor bacteria make this species unique. These distinct features set L. enzymogenes apart from well-studied plant beneficial biocontrol agents, such as Bacillus and Pseudomonas. This review describes what takes L. enzymogenes to be a unique biocontrol warrior by focusing to illustrate how the lack of flagellum governs morphological and functional co-adaptability, what adapted signaling transduction pathways are adopted to coordinate the biosynthesis of HSAF, and how to ecologically adapt plant rhizosphere by cell-to-cell interacting with microbiome members via the bacterial-killing T4SS.

Defensin, an essential component of plant development, is indispensable in pathogen resistance. However, the molecular function of defensins under pathological conditions of Cytospora canker has not been characterized in apple plants. The present study exhibits a detailed overview of the phylogeny and structure of 29 defensins(MdDEF) in apple. Expression analysis revealed that MdDEF genes were spatiotemporally diverse across apple tissues. Five MdDEF genes were found to be significantly up-regulated following a challenge with Cytospora mali. The transgenic overexpression of five defensin genes in apple calli enhanced resistance to C. mali. Among them, MdDEF30 was strongly induced and conferred the highest resistance level in ***, antifungal activity assays in vitro demonstrated that a recombinant protein produced from MdDEF30could inhibit the growth of C. mali. Notably, MdDEF30 promoted the accumulation of reactive oxygen species(ROS) and activated defense-related genes such as PR4, PR10, CML13, and MPK3. Co-expression regulatory network analysis showed that MdWRKY75 may regulate the expression of MdDEF30. Further yeast onehybrid(Y1H), luciferase, and chromatin Immunoprecipitation quantitative polymerase chain reaction(ChIPqPCR) assays verified that MdWRKY75 could directly bind to the promoter of MdDEF30. Importantly, pathogen inoculation assays confirmed that MdWRKY75 positively regulates resistance by transcriptionally activating MdDEF30. Overall, these results demonstrated that MdDEF30 promotes resistance to C. mali in apple plants and that MdWRKY75 regulates MdDEF30 expression during the induction of resistance, thereby clarifying biochemical mechanisms of resistance to C. mali in apple trees.

Bean（Phaseolus vulgaris） yields in Africa can be increased through the application of phosphorus and nitrogen fertilizers, as both nutrients are low in African soils. However, using greener technologies is preferred to mineral fertilizers for maintaining soil health. In this study, Rhizobium inoculation and moderate P supply(0, 10, 20, and 30 kg·ha-1) to two bean cultivars were evaluated in consecutive years at Hawassa for their effects on plant growth,nodulation, and grain yield. The results showed that, relative to the uninoculated control, the two bean cultivars responded strongly to Rhizobium inoculation, with strain HB-429 outperforming strain GT-9 in both 2012 and 2013. Shoot biomass, nodule number and nodule dry matter per plant were increased by 9%, 40%, and 54%, respectively, in 2012, and by 20%, 39%, and13% in 2013 with strain HB-429 inoculation. This resulted in increased pod number per plant, seed number per pod and grain yield by 56%, 51%, and 49%in 2012, and by 38%, 25%, and 69% in 2013, respectively, with strain HB-429inoculation. Bean inoculation with GT-9 also increased grain yield by 35% and68% in 2012 and 2013, respectively. Applying 10–30 kg·ha-1P to bean cultivars increased shoot biomass, nodule number, and nodule dry matter per plant by7% to 39%, 23% to 59%, and 59% to 144% in 2012, respectively, and by 10% to40%, 21% to 43%, and 12% to 35% in 2013, respectively. Relative to the zero-P control, adding only 10 kg·ha-1P increased pod number per plant, seed number per pod, and grain yield by 10%, 30%, and 61% in 2012, and by 11%,11%, and 38% in 2013, respectively. The combined use of Rhizobium inoculation with low P application(20 kg·ha-1) was found to increase bean production in Ethiopia and is thus recommended to resource-poor farmers.

The sugar beet cyst nematode(Heterodera schachtii) is one of the most destructive pathogens in sugar beet production, which causes serious economic losses every year. Few molecular details of effectors of H. schachtii parasitism are known. We analyzed the genome and transcriptome data of H. schachtii and identified multiple potential predicted proteins. After filtering out predicted proteins with high homology to other plant-parasitic nematodes, we performed functional validation of the remaining effector proteins. 37 putative effectors of H. schachtii were screened based on the Nicotiana benthamiana system for identifying the effectors that inhibit plant immune response, eventually determines 13 candidate effectors could inhibit cell death caused by Bax. Among the 13 effectors, nine have the ability to inhibit GPA2/RBP1-induced cell death. All 13 effectortriggered immunity(ETI) suppressor genes were analyzed by qRT-PCR and confirmed to result in a significant downregulation of one or more defense genes during infection compared to empty vector. For in situ hybridization,13 effectors were specifically expressed and located in esophageal gland cells. These data and functional analysis set the stage for further studies on the interaction of H. schachtii with host and H. schachtii parasitic control.

Tephritid fruit flies are considered one of the world’s most notorious pests of horticultural crops, including mango (Mangefera indica L.) in Sierra Leone, causing extensive direct and indirect damage. A survey was conducted among 60 mango farmers in 7 districts in Sierra Leone between June and August, 2022, to assess their perceptions regarding fruit fly pest status and the current management options adopted for the control of this pest. Semi-structured questions designed in an open and closed-ended fashion were used for the study. The majority (83%) of the farmers were already aware of the fruit fly problem in the country with 62% perceiving it to be very severe. The majority (60%) of farmers, however, demonstrated poor knowledge of identifying fruit fly species, especially Bactrocera dorsalis, Ceratitis capitata, and Ceratitis cosyra. Farmers were more conversant about the direct damage symptoms to host fruits and the economic impact of fruit flies. A total of 32% of growers took no action to control fruit flies on their farms. Sixty-nine percent (69%) of the farmers adopted cultural control measures, like practicing prompt harvesting, collection and disposal of infested fruits, and weeding to maintain better sanitary conditions on their farms. Recommended fruit fly management strategies such as the use of botanicals and resistant varieties were either unknown or inaccessible to growers. A total of 52% applied chemicals that were not recommended for the control of fruit flies without considering their environmental and health risks. It is important to train fruit growers to improve their capabilities for fruit fly management through extension agents that are appropriate for helping them acquire basic knowledge of fruit fly pests and their management.
