The root-knot nematode infects a variety of plants, including . During migration, root-knot nematodes secrete different proteins to modify cell walls, which include pectolytic enzymes. However, the contribution of host cell wall proteins has not been described during this process. The function of two DUF642 cell wall proteins, BIIDXI (BDX, ) and TEEBE (TEB, ), in plant development could be related to the regulation of pectin methyl esterification status in the cell walls of different tissues. Accordingly, the expression of these two genes is up-regulated by auxin. BDX and TEB were highly induced during early inoculation. Moreover, cell wall localization of the proteins was also induced. The cell wall localization of BDX and TEB DUF642 proteins during early inoculation suggested that these two proteins could be involved in the regulation of the degree of pectin methylation during cell separation.
根结线虫会感染多种植物，包括……在迁移过程中，根结线虫会分泌不同的蛋白质来修饰细胞壁，其中包括果胶分解酶。然而，在此过程中宿主细胞壁蛋白的作用尚未见描述。两种含DUF642结构域的细胞壁蛋白，BIIDXI（BDX，……）和TEEBE（TEB，……），在植物发育中的功能可能与不同组织细胞壁中果胶甲酯化状态的调节有关。因此，这两个基因的表达受生长素上调。BDX和TEB在早期接种时被高度诱导。此外，这些蛋白质的细胞壁定位也被诱导。BDX和TEB DUF642蛋白在早期接种时的细胞壁定位表明，这两种蛋白可能参与细胞分离过程中果胶甲基化程度的调节。
