Overexpression of a cytosol-localized rhamnose biosynthesis protein encoded by Arabidopsis RHM1 gene increases rhamnose content in cell wall

l-Rhamnose (Rha) is an important constituent of pectic polysaccharides, a major component of the cell walls of Arabidopsis, which is synthesized by three enzymes encoded by AtRHM1, AtRHM2/AtMUM4, and AtRHM3. Despite the finding that RHM1 is involved in root hair formation in Arabidopsis, experimenta...

520 |a l-Rhamnose (Rha) is an important constituent of pectic polysaccharides, a major component of the cell walls of Arabidopsis, which is synthesized by three enzymes encoded by AtRHM1, AtRHM2/AtMUM4, and AtRHM3. Despite the finding that RHM1 is involved in root hair formation in Arabidopsis, experimental evidence is still lacking for the in vivo enzymatic activity and subcellular compartmentation of AtRHM1 protein. AtRHM1 displays high similarity to the other members of RHM family in Arabidopsis and in other plant species such as rice and grape. Expression studies with AtRHM1 promoter-GUS fusion gene showed that AtRHM1 was expressed almost ubiquitously, with stronger expression in roots and cotyledons of young seedlings and inflorescences. GFP::AtRHM1 fusion protein was found to be localized in the cytosol of cotyledon cells and of petiole cells of cotyledon, indicating that AtRHM1 is a cytosol-localized protein. The overexpression of AtRHM1 gene in Arabidopsis resulted in an increase of rhamnose content as much as 40% in the leaf cell wall compared to the wild type as well as an alteration in the contents of galactose and glucose. Fourier-transform infrared analyses revealed that surplus rhamnose upon AtRHM1 overexpression contributes to the construction of rhamnogalacturonan
