- LRR-extensins (LRX) form a family of structural cell wall proteins containing a receptor-like domain. The functional analysis of Arabidopsis LRX1 has shown that it is involved in cell morphogenesis of root hairs. In this work (1)

- a paralog of LRX1. LRX2 expression is mainly found in roots and is responsive to factors promoting or repressing root hair formation. The function of LRX1 and LRX2 was tested by the expression of a truncated LRX2 and different LRX1/LRX2 chimaeric proteins. Using complementation of the lrx1 phenotype as the parameter for protein function (1)
- and that they likely regulate cell morphogenesis by promoting proper development of the cell wall. (1)
- as well as local disintegration of the wall structure in the double mutant (1)
- but not in wild-type plants. Our results indicate that LRX1 and LRX2 have overlapping functions in root hair formation (1)
- but synergistically interact with the lrx1 mutation. lrx1/lrx2 double mutants have a significantly enhanced lrx1 phenotype (1)
- our experiments indicate that LRX1 and LRX2 are functionally similar but show differences in their activity. Genetic analysis revealed that single lrx2 mutants do not show any defect in root hair morphogenesis (1)
- resulting in frequent rupture of the root hairs soon after their initiation. Analysis of the root hair cell wall ultrastructure by transmission electron microscopy (TEM) revealed the formation of osmophilic aggregates within the wall (1)
