Leucine-rich repeat extensins (LRXs) are extracellular proteins consisting of an N-terminal leucine-rich (LRR) domain and a C-terminal extensin containing the typical features this class structural hydroxyproline-rich glycoproteins (HRGPs). The LRR is likely to bind interaction partner, whereas has anchoring function insolubilize protein in cell wall. Based on analysis root hair-expressed LRX1 LRX2 Arabidopsis thaliana, LRX important for wall development. importance non-root hair cells...
Abstract The oxidation of monolignols is a required step for lignin polymerization and deposition in cell walls. In dicots, both peroxidases laccases are known to participate this process. Here, we provide evidence that also involved the lignification Brachypodium distachyon, model plant temperate grasses. Transcript quantification data as well situ immunolocalization experiments demonstrated at least two (LACCASE5 LACCASE6) present lignifying tissues. A mutant with misspliced LACCASE5...
Cell-to-cell adhesion in plants is mediated by the cell wall and presence of a pectin-rich middle lamella. However, we know very little about how plant actually controls maintains during growth development it deals with dynamic remodeling that takes place. Here investigate molecular mechanisms control plants. We carried out genetic suppressor screen analysis adhesion-defective Arabidopsis thaliana mutants. identified defect affecting putative O-fucosyltransferase. Furthermore, show state not...

eskimo1 -5 (esk1-5) is a dwarf Arabidopsis (Arabidopsis thaliana) mutant that has constitutive drought syndrome and collapsed xylem vessels, along with low acetylation levels in xylan mannan. ESK1 O-acetyltransferase activity vitro. We used suppressor strategy on esk1-5 to screen for variants wild-type growth levels, favorable combination ethanol production. found recessive mutation the KAKTUS (KAK) gene suppressed dwarfism character, cause of decreased hydraulic conductivity mutant....
Homogalacturonan (HG) is the main component of pectins. HG methylesterification has recently emerged as a key determinant controlling cell attachment, organ formation, and phyllotaxy. However, whether how affects intercellular metabolite transport rarely been reported. Here, we identified characterized knockout mutants rice (Oryza sativa) OsQUA2 gene encoding putative pectin methyltransferase. Osqua2 exhibit remarkable decrease in degree culm-sieve element wall markedly reduced grain yield....
The CUP-SHAPED COTYLEDON (CUC) transcription factors control plant boundary formation, thus allowing the emergence of novel growth axes. While developmental roles CUC genes in different organs and across species are well characterized, upstream downstream events that contribute to their function still poorly understood. To identify new players this network, we performed a suppressor screen CUC2g-m4, line overexpressing CUC2 has highly serrated leaves. We identified mutation simplifies leaf...
