Protein

Expansin-A3

Gene

EXPA3

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

May cause loosening and extension of plant cell walls by disrupting non-covalent bonding between cellulose microfibrils and matrix glucans. No enzymatic activity has been found. May be required for rapid internodal elongation in deepwater rice during submergence (By similarity).By similarity
