“…Phylogenetic analysis shows that these members can be divided into five clades ( Figure 1 ). Previous phylogenetic studies on WAK/WAKL proteins in cotton [ 7 ], tomato [ 34 ], barley [ 25 ] and other plants have found that these proteins tend to form species-specific clades. The most WAK/WAKL proteins in Arabidopsis clustered in the same group compared with other species [ 7 , 34 , 35 ].…”

Wall-associated kinase (WAK) and WAK-like kinase (WAKL) are receptor-like kinases (RLKs), which play important roles in signal transduction between the cell wall and the cytoplasm in plants. WAK/WAKLs have been studied in many plants, but were rarely studied in the important economic walnut tree. In this study, 27 and 14 WAK/WAKL genes were identified in Juglans regia and its wild related species Juglans mandshurica, respectively. We found tandem duplication might play a critical role in the expansion of WAK/WAKL gene family in J. regia, and most of the WAK/WAKL homologous pairs underwent purified selection during evolution. All WAK/WAKL proteins have the extracellular WAK domain and the cytoplasmic protein kinase domain, and the latter was more conserved than the former. Cis-acting elements analysis showed that WAK/WAKL might be involved in plant growth and development, plant response to abiotic stress and hormones. Gene expression pattern analysis further indicated that most WAK/WAKL genes in J. regia might play a role in the development of leaves and be involved in plant response to biotic stress. Our study provides a new perspective for the evolutionary analysis of gene families in tree species and also provides potential candidate genes for studying WAK/WAKL gene function in walnuts.

“…Characterizing the WAK gene family will help identify many new candidate genes that may contribute to disease resistance. Presently, WAK gene families have been identified and characterized in diverse plant species, including 26 members in Arabidopsis [3], 125 in rice [27], 91 in barley [28], 27 in walnuts [29], 29 in tomato [25], 29 in potato [36], and 29 in cotton [26]. Although several wheat WAKs have been reported, their genome-wide characterization in the complicated wheat hexaploid genome is lacking.…”

Wall-associated kinases (WAKs) are important receptor-like proteins that play major roles in plant defense against pathogens. Fusarium head blight (FHB), one of the most widespread and devastating crop diseases, reduces wheat yield and leads to quality deterioration. Although WAK gene families have been studied in many plants, systematic research on bread wheat (Triticum aestivum) and its role in FHB resistance, in particular, is lacking. In this study, we identified and characterized 320 genes of the TaWAK family in wheat distributed across all chromosomes except 4B and divided them into three phylogenetic groups. Duplication and synteny analyses provided valuable information on the evolutionary characteristics of the TaWAK genes. The gene expression pattern analysis suggested that TaWAK genes play diverse roles in plant biological processes and that at least 30 genes may be involved in the response to Fusarium infection in wheat spikes, with most of the genes contributing to pectin- and chitin-induced defense pathways. Furthermore, 45 TaWAK genes were identified within 17 hcmQTLs that are related to wheat FHB resistance. Our findings provide potential candidate genes for improving FHB resistance and insights into the future functional analysis of TaWAK genes in wheat.

Plant cell wall associated kinases (WAKs) and WAK-like kinases (WAKLs) have been increasingly recognized as important regulators of plant immunity against various plant pathogens. However, the role of the WAK / WAKL family in plant-nematode interactions remains to be determined. Here, we analyzed a WAK -encoding gene ( Soltu.DM.02G029720.1 ) from potato ( Solanum tuberosum ). The Soltu.DM.02G029720.1 encoded protein contains domains characteristic of WAK/WAKL proteins and shows the highest similarity to SlWAKL2 from tomato ( S. lycopersicum ). We thus named the gene as StWAKL2 . Phylogenetic analysis of a wide range of plant WAKs/WAKLs further revealed close similarity of StWAKL2 to three WAK/WAKL proteins demonstrated to play a role in disease resistance. To gain insights into the potential regulation and function of StWAKL2 , transgenic potato lines containing the StWAKL2 promoter fused to the β-glucuronidase (GUS) reporter gene were generated and used to investigate StWAKL2 expression during plant development and upon nematode infection. Histochemical analyses revealed that StWAKL2 has specific expression patterns in potato leaf and root tissues. During nematode infection, GUS activity was mostly undetected at nematode infection sites over the course of nematode parasitism, although strong GUS activity was observed in root tissues adjacent to the infection region. Furthermore, mining of the transcriptomic data derived from cyst nematode infection of Arabidopsis roots identified a few WAK / WAKL genes, including a StWAKL2 homologue, found to be significantly down-regulated in nematode-induced feeding sites. These results indicated that specific suppression of WAK / WAKL genes in nematode-induced feeding sites might be crucial for cyst nematodes to achieve successful infection of host plants. Further studies are needed to uncover the role of WAK / WAKL genes in plant defenses against nematode infection.
