Expression of pathogenesis related genes in response to salicylic acid, methyl jasmonate and 1-aminocyclopropane-1-carboxylic acid in Malus hupehensis (Pamp.) Rehd

Abstract

The results showed that a distinct pattern of expression of PR genes in Malus hupehensis which differed from the previous reports on model plants arabidopsis, tobacco and rice. MhPR1, MhPR5 and MhPR8 were induced by SA, MeJA and ACC, which were regarded as the marker genes in the SAR response in Malus hupehensis. In contrast with herbal plants, there could be specific signal pathway in response to SA, JA and ET for woody plants.
