Biological function of pathogenesis-related proteins: Four tobacco pathogenesis-related proteins are chitinases.

M Legrand et al.

Proceedings of the National Academy of Sciences of the United States of America, 84(19), 6750-6754 (1987-10-01)

Four endochitinases (poly[1,4-(N-acetyl-beta-D-glucosaminide)] glycanohydrolase, EC 3.2.1.14) have been purified from leaves of Nicotiana tabacum cv. Samsun NN reacting hypersensitively to tobacco mosaic virus. Two of them are acidic proteins of molecular weights 27,500 and 28,500 and have been identified as

Selective differentiation of indoleacetic acid and indolebutyric acid using colorimetric recognition after Ehrlich reaction.

Jun-Min Guo et al.

Journal of agricultural and food chemistry, 58(11), 6556-6561 (2010-05-15)

A simple colorimetric method for the differentiation of indoleacetic acid (IAA) and indolebutyric acid (IBA) in plant samples is described. The color change is based upon the reaction between the auxins and p-(dimethylamino)benzaldehyde (PDAB, Ehrlich reagent) following the electrophilic substitution
