BACKGROUND The soil-borne fungal pathogen Verticillium dahliae Kleb causes Verticillium wilt in a wide range of crops including cotton (Gossypium hirsutum). To date, most upland cotton varieties are susceptible to V. dahliae and the breeding for cotton varieties with the resistance to Verticillium wilt has not been successful. RESULTS Hpa1Xoo is a harpin(More)
Uncoupling protein (UCP1) is a transmembrane proton transporter present in the mitochondria of brown adipose tissue (BAT), a specialized tissue which functions in temperature homeostasis and energy balance (Nicholls, D. G., and Locke, R. M. (1984) Physiol. Rev. 64, 2-40; Lowell, D. D., and Flier, J. S. (1997) Annu. Rev. Med.). UCP1 mediates the(More)
The transcriptome profile in leaves and roots of the transgenic cotton line T-34 expressing hpa1(Xoo) from Xanthomonas oryzae pv. oryzae was analysed using a customized 12k cotton cDNA microarray. A total of 530 cDNA transcripts involved in 34 pathways were differentially expressed in the transgenic line T-34, in which 123 differentially expressed genes(More)
Harpin proteins stimulate hypersensitive response (HR) in plants. However, the mechanism by which HR is regulated is not clear. The role of the auxin, indole-3-acetic acid (IAA), in the control of harpin-stimulated HR was investigated. IAA was used to inhibit HR that was stimulated by purified fusion harpinXoo protein in tobacco. Semi-quantitative PCR and(More)
Powdery mildew is an important disease of rubber trees caused by Oidium heveae B. A. Steinmann. As far as we know, none of the resistance genes related to powdery mildew have been isolated from the rubber tree. There is little information available at the molecular level regarding how a rubber tree develops defense mechanisms against this pathogen. We have(More)
Harpin proteins encoded by hrp genes are bacterial protein elicitors that can stimulate hypersensitive response (HR) in non-host plants. HR-related pathogen resistance involves a complex form of programmed cell death (PCD). It is increasingly viewed as a key component of the hypersensitive disease response of plants. Currently, the evidence of harpin(More)
