... 2006) doi:10.1111/j.1742-4658.2006.05249.x A novel elicitor that induces chitinases in tobacco BY-2 cells was isolated from Alternaria alternata 102. Six other fungi, including A. alternata IFO 6587, could not induce, or weakly induce ... genes. In comparison with laminarin and laminarin sulfate, which are reported to be potent elicitors of defense responses in tobac...

... detected, indicating that calpain had undergone a transition from the low to the high affinity mAb-binding form. Interestingly, these results obtained in vivo were almost superimposable on those obtained ... the intensity of calpain staining increased 7– 8-fold, indicating that the protease was now mainly present in the high-affinity form. In these conditions, although the highest amoun...
