A wound- and systemin-inducible polygalacturonase in tomato leaves.
Oligogalacturonide fragments that activate defensive genes in plant leaves heretofore have been thought to be generated only by pathogen-derived pectin-degrading enzymes, because polygalacturonase (PG) activity has not been reported in leaves. Here, we report that mRNAs encoding a PG catalytic subunit protein and its regulatory (beta-subunit) protein are expressed in tomato leaves in response t...
متن کاملAnalysis of Clonostachys rosea-Induced Resistance to Tomato Gray Mold Disease in Tomato Leaves
Tomato gray mold disease, caused by Botrytis cinerea, is a serious disease in tomato. Clonostachys rosea is an antagonistic microorganism to B. cinerea. To investigate the induced resistance mechanism of C. rosea, we examined the effects of these microorganisms on tomato leaves, along with changes in the activities of three defense enzymes (PAL, PPO, GST), second messengers (NO, H2O2, O2(-)) an...
متن کاملMethyl Jasmonate Induces Papain Inhibitor(s) in Tomato Leaves.
Leaves of 18- to 24-d-old tomato (Lycopersicon esculentum) plants exposed to gaseous methyl jasmonate (MJ) for 24 h at 30[deg]C in continuous light contained high levels of soluble protein that inhibited papain. Chromatographic analysis demonstrated that the active protein had a molecular mass of 80 to 90 kD. Induction of papain inhibitor was directly related to the concentration of air-borne M...
متن کاملIngress of Salmonella enterica Typhimurium into Tomato Leaves through Hydathodes
Internal contamination of Salmonella in plants is attracting increasing attention for food safety reasons. In this study, three different tomato cultivars "Florida Lanai", "Crown Jewel", "Ailsa Craig" and the transgenic line Sp5 of "Ailsa Craig" were inoculated with 1 µl GFP-labeled Salmonella Typhimurium through guttation droplets at concentrations of 10(9) or 10(7) CFU/ml. Survival of Salmone...
متن کاملEffector XopD suppresses tissue degeneration in Xanthomonas-infected tomato leaves.
Some plant pathogens deploy dozens of effector proteins through the type III secretion apparatus into host cells. These effectors manipulate host basal defenses and metabolism to the advantage of the pathogen, a process essential for pathogenesis (reviewed in Mudgett 2005; Grant et al., 2006). Effectors can also betray the presence of the pathogen, triggering robust plant defense responses that...
