Expression analysis of genes encoding malectin-like domain (MLD)- and leucine-rich repeat (LRR)- containing proteins in Arabidopsis thaliana
Malectin is a maltose-binding endoplasmic reticulum protein conserved in animals. In Arabidopsis thaliana, we identified four genes that encode malectin-like domain (MLD)- and leucine-rich repeat (LRR)-containing proteins (AtMLLRs): two were receptor-like proteins (AtMLLR1 and 2) and the other two were extracellular proteins (AtMLLR3 and 4). The promoter:G3GFP+promoter:GUS assay indicated the organ- and cell-specific expression of the AtMLLR2 and AtMLLR3 genes.
