National Institute of Agrobiological Science Deciphers Amino-acid Sequence of Elicitor Using Rice.Tokyo, Japan, Aug 4, 2006 - (JCN) - The National Institute of Agrobiological ag·ro·bi·ol·o·gy n. The study of plant nutrition and growth in relation to soil conditions, especially to determine ways to increase crop yields. ag Science (NIAS) has discovered the protein 'CEBip', Chitin Elicitor Binding Protein and succeeded in the long awaited deciphering of the Amino-acid Sequence of the Elicitor, known as Chitin oligosaccharides oligosaccharides (ol´igōsak´  rīdz),n. . The elicitor has been known to induce various defense responses in a wide range of plant cells. NIAS in collaboration with RIKEN RIKEN Rikagaku Kenkyusho (Institute of Physical and Chemical Research, Japan) and Meiji University binded rice with chitin oligosaccharides and extracted CEBiP from its plasma membrane receptor. The deciphering showed that CEBiP is a glycoprotein consisting of 328 amino acid residues and glycan chains. It plays a key role in the perception of chitin oligosaccharide oligosaccharide: see carbohydrate. oligosaccharide Any carbohydrate with a few (between 3 and about 6 to 10) units of simple sugars (monosaccharides). A wide variety of oligosaccharides are made by partially breaking down polysaccharides. elicitor in the rice cells. Forward looking discovery will lead to a new study in coming up with a n improved disesase- resistant gene for plants. Copyright [c] 2006 Japan Corporate News Network. All rights reserved. |
