Publikováno v: Molecules, Vol 19, Iss 11, Pp 18033-18056 (2014)

Phytoalexins are low molecular weight antimicrobial compounds that are produced by plants as a response to biotic and abiotic stresses. As such they take part in an intricate defense system which enables plants to control invading microorganisms. In

Publikováno v: Molecular Plant-Microbe Interactions, Vol 11, Iss 11, Pp 1102-1109 (1998)

Expression of tobacco class I (CAT1) and class II (CAT2) catalases was analyzed in leaves reacting hypersensitively to tobacco mosaic virus (TMV) or to a fungal glycoprotein elicitor. In TMV-infected plants, Cat1 transcript levels declined rapidly wh
