Abstract
Background NDR1/HIN1-like (NHL) family genes are known to be involved in pathogen induced plant responses to biotic stress. Even though the NHL family genes have been identified and characterized in plant defense responses in some plants, the roles of these genes associated with the plant abiotic stress tolerance in wild soybean is not fully established yet, especially in response to alkaline stress. Methods We identified the potential NHL family genes by using the Hidden Markov model and wild soybean genome. The maximum-likelihood phylogenetic tree and conserved motifs were generated by using the MEME online server and MEGA 7.0 software, respectively. Furthermore, the syntenic analysis was generated with Circos-0.69. Then we used the PlantCARE online software to predict and analyze the regulatory cis-acting elements in promoter regions. Hierarchical clustering trees was generated using TM4: MeV4.9 software. Additionally, the expression levels of NHL family genes under alkaline stress, ABA and MEJA treatment were identified by qRT-PCR. Results In this study, we identified 59 potential NHL family genes in wild soybean. We identified that wild soybean NHL family genes could be mainly classified into five groups as well as exist with conserved motifs. Syntenic analysis of NHL family genes revealed genes location on 18 chromosomes and presence of 65 pairs of duplication genes. Moreover, NHL family genes consisted of a variety of putative hormone-related and abiotic stress responsive elements, where numbers of methyl jasmonate (MeJA) and abscisic acid (ABA) responsive elements were significantly larger than other elements. We confirmed the regulatory roles of NHL family genes in response to alkaline stress, ABA and MEJA treatment. In conclusion, we identified and provided valuable information on the wild soybean NHL family genes, and established a foundation to further explore the potential roles of NHL family genes in crosstalk with MeJA or ABA signal transduction mechanisms under alkaline stress.

Overexpression of a pathogenesis-related gene NbHIN1 confers resistance to Tobacco Mosaic Virus in Nicotiana benthamiana by potentially activating the jasmonic acid signaling pathway. PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2019; 283:147-156.

Abstract
Harpin proteins secreted by plant-pathogenic gram-negative bacteria induce diverse plant defenses against different pathogens. Harpin-induced 1 (HIN1) gene highly induced in tobacco after application of Harpin protein is involved in a common plant defense pathway. However, the role of HIN1 against Tobacco mosaic virus (TMV) remains unknown. In this study, we functionally characterized the Nicotiana benthamiana HIN1 (NbHIN1) gene and generated the transgenic tobacco overexpressing the NbHIN1 gene. In a subcellular localization experiment, we found that NbHIN1 localized in the plasma membrane and cytosol. Overexpression of NbHIN1 did not lead to observed phenotype compared to wild type tobacco plant. However, the NbHIN1 overexpressing tobacco plant exhibited significantly enhanced resistance to TMV infection. Moreover, RNA-sequencing revealed the transcriptomic profiling of NbHIN1 overexpression and highlighted the primary effects on the genes in the processes related to biosynthesis of amino acids, plant-pathogen interaction and RNA transport. We also found that overexpression of NbHIN1 highly induced the expression of NbRAB11, suggesting that jasmonic acid signaling pathway might be involved in TMV resistance. Taken together, for the first time we demonstrated that overexpressing a pathogenesis-related gene NbHIN1 in N. benthamiana significantly enhances the TMV resistance, providing a potential mechanism that will enable us to engineer tobacco with improved TMV resistance in the future.

Identification and characterization of the Non-race specific Disease Resistance 1 (NDR1) orthologous protein in coffee. BMC PLANT BIOLOGY 2011; 11:144.

Abstract
BACKGROUND Leaf rust, which is caused by the fungus Hemileia vastatrix (Pucciniales), is a devastating disease that affects coffee plants (Coffea arabica L.). Disadvantages that are associated with currently developed phytoprotection approaches have recently led to the search for alternative strategies. These include genetic manipulations that constitutively activate disease resistance signaling pathways. However, molecular actors of such pathways still remain unknown in C. arabica. In this study, we have isolated and characterized the coffee NDR1 gene, whose Arabidopsis ortholog is a well-known master regulator of the hypersensitive response that is dependent on coiled-coil type R-proteins. RESULTS Two highly homologous cDNAs coding for putative NDR1 proteins were identified and cloned from leaves of coffee plants. One of the candidate coding sequences was then expressed in the Arabidopsis knock-out null mutant ndr1-1. Upon a challenge with a specific strain of the bacterium Pseudomonas syringae (DC3000::AvrRpt2), analysis of both macroscopic symptoms and in planta microbial growth showed that the coffee cDNA was able to restore the resistance phenotype in the mutant genetic background. Thus, the cDNA was dubbed CaNDR1a (standing for Coffea arabica Non-race specific Disease Resistance 1a). Finally, biochemical and microscopy data were obtained that strongly suggest the mechanistic conservation of the NDR1-driven function within coffee and Arabidopsis plants. Using a transient expression system, it was indeed shown that the CaNDR1a protein, like its Arabidopsis counterpart, is localized to the plasma membrane, where it is possibly tethered by means of a GPI anchor. CONCLUSIONS Our data provide molecular and genetic evidence for the identification of a novel functional NDR1 homolog in plants. As a key regulator initiating hypersensitive signalling pathways, CaNDR1 gene(s) might be target(s) of choice for manipulating the coffee innate immune system and achieving broad spectrum resistance to pathogens. Given the potential conservation of NDR1-dependent defense mechanisms between Arabidopsis and coffee plants, our work also suggests new ways to isolate the as-yet-unidentified R-gene(s) responsible for resistance to H. vastatrix.

Abstract
Actinorhizal plants have become increasingly important as climate changes threaten to remake the global landscape over the next decades. These plants are able to grow in nutrient-poor and disturbed soils, and are important elements in plant communities worldwide. Besides that, most actinorhizal plants are capable of high rates of nitrogen fixation due to their capacity to establish root nodule symbiosis with N2-fixing Frankia strains. Nodulation is a developmental process that requires a sequence of highly coordinated events. One of these mechanisms is the induction of defence-related events, whose precise role in a symbiotic interaction remains to be elucidated. This review summarises what is known about the induction of actinorhizal defence-related genes in response to symbiotic Frankia and their putative function during symbiosis.

Abstract
The reduction of phytochemicals applied to grapevine relies on the development of alternative strategies involving activation of the plant's own defense system. The aim of this work was to study the signaling of defense responses to pathogens in Vitis vinifera. We identified in V. vinifera cv. Chardonnay two putative regulatory elements, VvNHL1 and VvEDS1, with similarity to Arabidopsis defense regulators NDR1 and EDS1. Expression studies of these putative signaling genes together with other known grape defense genes show that they are differentially regulated by salicylic acid and jasmonate-ethylene treatments, as well as by inoculation with different types of pathogens. The expression of VvEDS1 was stimulated by salicylic acid treatment, Botrytis cinerea and Plasmopara viticola inoculation, whereas VvNHL1 was repressed by B. cinerea. VvNHL1 overexpression introduced in Arabidopsis ndr1 mutant did not complement the mutation in terms of sensitivity to avirulent Pseudomonas syringae pv. tomato. Moreover, we observed a weakened resistance to B. cinerea of ndr1 mutants overexpressing VvNHL1, which may be related to cell death enhancement. Together, our results identify two new pathogen-responsive regulatory elements in Vitis vinifera, with potential roles in pathogen defense.
