Cover Story: Wall-associated kinases/kinase-likes (WAKs/WAKLs) are plant cell surface sensors. The role of WAKs/WAKLs during the development of the secondary cell walls (SCWs) remains unclear. In this study, we used RNA-seq data to screen Arabidopsis thaliana WAKs/WAKLs members that may be involved in SCW development and identified WAKL8 as a candidate. Decreased WAKL8 transcript levels in stems were found in wakl8-2 T-DNA insertion mutant plants, and the phenotypes observed included reduced stem length and thinner walls in cells with secondary walls, including xylem vessels and interfascicular fibers, compared with WT plants. We also found that WAKL8 had alternative spliced versions predicted to have only extracellular regions, which may interfere with the function of the full-length version of WAKL8.
