“…AtLBD20 was induced by F. oxysporum, and the overexpression of LBD20 was correlated with increased susceptibility to infection and reduced the expression of JA-regulated genes VEGETATIVE STORAGE PROTEIN2 (VSP2) and THI-ONIN2.1 (Thi2.1). Other LOB domain family genes were also detected to be responsive to fungal and root pathogens from public Arabidopsis array data (40). Here, we showed that CsLOB1 expression is associated with expression of numerous cell wall-related enzymes, indicating a possible function in cell wall biochemistry.…”

Significance Citrus bacterial canker, which is caused by several species in the genus Xanthomonas , is a severe disease with worldwide distribution affecting all the commercially important citrus species and cultivars. The mechanisms of canker development, involving erumpent pustule formation and bacterial growth, are not known. Our findings suggest that virulence determinants in several pathogens activate a single host disease susceptibility (S) gene that has a critical contribution to bacterial growth and host pustule development. The S gene represents an excellent candidate for control measures for the citrus bacterial canker.

“…Among the soybean LBD family, a total of 27 genes (30%) were induced by the different treatments, and these genes included 17 of 74 Class I genes (23%) and 10 of 16 Class II genes (62.5%), suggesting that Class II genes have a greater role in plant stress responses than Class I genes. Previous work in Arabidopsis demonstrated that LBD genes whose expression is responsive to multiple pathogens belong to the smaller Class II of LBD proteins (subgroups formed between AtLBD37 , 38 , and 39 and AtLBD40 , 41 , and 42 ) and that Class II LBD genes are the most responsive (Thatcher et al, 2012a). Consistent with these findings, our investigation of soybean biotic stress responses revealed that Class II LBD genes in soybean, particularly GmLBD23 , 30 , 37 , 45 , 51 , and 70 , are induced by more varieties of pathogens than Class I genes and are maintained at a higher expression level after infection (supported by microarray data).…”

Plant-specific LBD (LATERAL ORGAN BOUNDARIES Domain) genes play critical roles in various plant growth and development processes. However, the number and characteristics of LBD genes in soybean [Glycine max (L.) Merr.] remain unknown. Here, we identified 90 LBD homologous genes in the soybean genome that phylogenetically clustered into two classes (I and II). The majority of the GmLBD genes were evenly distributed across all 20 soybean chromosomes, and 77 (81.11%) of them were detected in segmental duplicated regions. Furthermore, the exon-intron organization and motif composition for each GmLBD were analyzed. A close phylogenetic relationship was identified between the soybean LBD genes and 41 previously reported genes of different plants in the same group, providing insights into their putative functions. Expression analysis indicated that more than half of the LBD genes were expressed, with the two gene classes showing differential tissue expression characteristics; in addition, they were differentially induced by biotic and abiotic stresses. To further explore the functions of LBD genes in soybean, GmLBD12 was selected for functional characterization. GmLBD12 was mainly localized to the nucleus and showed high expression in root and seed tissues. Overexpressing GmLBD12 in Arabidopsis thaliana (L.) Heynh resulted in increases in lateral root (LR) number and plant height. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis demonstrated that GmLBD12 was induced by drought, salt, cold, indole acetic acid (IAA), abscisic acid (ABA), and salicylic acid SA treatments. This study provides the first comprehensive analysis of the soybean LBD gene family and a valuable foundation for future functional studies of GmLBD genes.

“…Cascading mechanisms leading to plant defence often operate at the transcriptional level through intricate regulation, ultimately resulting in increased expression of defence-related genes (Le Hénanff et al, 2013;Tsuda and Somssich, 2015). Extensive studies have revealed that stress-responsive genes are mainly regulated by multiple transcriptionally and/or post-translationally activated transcription factors (TFs) (Llorca et al, 2014;Thatcher et al, 2012;Tsuda and Somssich, 2015). TFs are grouped into different families based on conserved structural domains.…”

SUMMARYPlants respond to pathogen attack by the modulation of a large set of genes, which are regulated by different types of transcription factor (TF). NAC (NAM/ATAF/CUC) and WRKY are plant-specific families of TFs, and have received much attention as transcriptional regulators in plant pathogen defence. However, the cooperation between NAC and WRKY TFs in the disease response remains largely unknown. Our previous study has revealed that two banana fruit WRKY TFs, MaWRKY1 and MaWRKY2, are involved in salicylic acid (SA)-and methyl jasmonate (MeJA)-induced resistance against Colletotrichum musae via binding to promoters of pathogenesis-related (PR) genes. Here, we found that MaNAC1, MaNAC2 and MaNAC5 were up-regulated after C. musae infection, and were also significantly enhanced by SA and MeJA treatment. Protein-protein interaction analysis showed that MaNAC5 physically interacted with MaWRKY1 and MaWRKY2. More importantly, dual-luciferase reporter (DLR) assay revealed that MaNAC5, MaWRKY1 and MaWRKY2 were transcriptional activators, and individually or cooperatively activated the transcriptional activities of MaPR1-1, MaPR2, MaPR10c and MaCHIL1 genes. Collectively, our results indicate that MaNAC5 cooperates with MaWRKY1 and MaWRKY2 to regulate the expression of a specific set of PR genes in the disease response, and to contribute at least partially to SAand MeJA-induced pathogen resistance.
