Antagonistic functions of CTL1 and SUH1 mediate cell wall assembly in Arabidopsis.

ABSTRACT: Plant genomes contain numerous genes encoding chitinase-like (CTL) proteins, which have a similar protein structure to chitinase belonging to the glycoside hydrolase (GH) family but lack the chitinolytic activity to cleave the β-1,4-glycosidic bond in chitins, polymers of N-acetylglucosamine. CTL1 mutations found in rice and Arabidopsis have caused pleiotropic developmental defects, including altered cell wall composition and decreased abiotic stress tolerance, likely due to reduced cellulose content. In this study, we identified suppressor of hot2 1 (suh1) as a genetic suppressor of the ctl1 ^hot2-1 mutation in Arabidopsis. The mutation in SUH1 restored almost all examined ctl1 ^hot2-1
