Outline of Final Research Achievements

Pectin is one of the cell wall polysaccharides and important for plant development. Little is known about the effect of exogeneous pectin on plants. To understand the functions of exogeneous pectin, pectin oligosaccharide was treated young rice roots. Pectin treated rice showed more root extension and pathogen resistance. Proteome and mRNA-seq analyses also showed the overexpression of gibberellin responsive genes and pathogen resistance genes. Our date indicates that galacturonic acids, which is the smallest unit of pectin, play signal molecule directly and induce root extension and pathogen resistance.
