The crude culture supernatants from Clostridium cellulovorans were tested for their ability to convert plant cells to protoplasts. The supernatants readily released protoplasts from cultured tobacco cells and Arabidopsis thaliana. The crude culture supernatant from pectin-grown cells was more active
The adhesion of water-soluble beta-d-glycans, including cellulose-adhesive schizophyllan, xyloglucan, and locust bean gum to intact cells and protoplasts of Nicotiana tabacum BY-2 was examined using their fluorescent derivatives. Fluorescence microscopy showed that schizophyllan, xyloglucan, locust
Oligosaccharide, a typical danger-associated molecular pattern (DAMP), has been studied and applied as plant defence elicitor for several years. Here, we report a novel oligosaccharide, mannan oligosaccharide (MOS) with a degree of polymerization of 2-6, which was hydrolysed from locust bean gum by
A lectin was isolated from Agrobacterium radiobacter cell surface and purified. It is a monomer of 40 kDa as shown by SDS-PAGE. The lectin has a pI of 9.15 and amino acid composition of the lectin shows that 44% of the amino acids are hydrophobic. The lectin agglutinates rabbit erythrocytes but does
An index [kv: average isolation rate of viable protoplast (number/ml min)] was established to evaluate the optimal conditions for protoplast isolation from cultured plant cells. The optimal conditions for protoplasts isolation from Nicotiana tabacum BY2 cultured cells could be determined on the
