    Abstract:
    Two biotic stress resistance related genes from the full-length cDNA library of Brassica rapa cv. Osome were identified from EST analysis and determined to be pathogenesis-related (PR) 12 Brassica defensin-like family protein (BrDLFP) and PR-10 Brassica Betv1 allergen family protein (BrBetv1AFP) after sequence analysis and homology study with other stress resistance related same family genes. In the expression analysis, both genes expressed in different organs and during all developmental growth stages in healthy plants. Expression of BrDLFP significantly increased and BrBetv1AFP gradually decreased after infection with Pectobacterium carotovorum subsp. carotovorum in Chinese cabbage. Expression of these two genes significantly changed after cold, salt, drought and ABA stress treatments. These two PR genes may therefore be involved in the plant resistance against biotic and abiotic stresses.
