Citation: Liu, J., Bell, A.A., Wagner, T.A., Stipanovic, R.D., Gu, A., Crutcher, F.K., Puckhaber, L.S. 2016. Physiology of host-pathogen interaction in wilt diseases of cotton in relation to pathogen management. In: Snider, J.L., Oosterhuis, D. M., editors. Cordova, TN: The Cotton Foundation Reference Book Series. p.117-146.

Interpretive Summary: This chapter summarized current knowledge on the various aspects of the pathogen-host interaction regarding various types of pathogens, the disease causing determinants, and nature of host defenses. Practices and strategies to manipulate these processes to suppress and manage the disease are discussed.

Technical Abstract: Verticillium and Fusarium wilts are important vascular wilt diseases of cotton that significantly reduce cotton yields and negatively impact fiber quality. In spite of intense efforts to control these diseases, yield losses persist and in the US alone were estimated to be about 133 and 28 thousand bales of cotton, respectively, for 2014. Management of these diseases depends largely on host resistance. Despite considerable progress in host resistance breeding, complete control remains difficult mainly due to the lack of high levels of resistance in cotton. Management of the diseases is further complicated by the spread of new highly virulent pathogens. The disease outcome depends on the complex interaction between the pathogen and cotton host which is further influenced by the abiotic and biotic environmental factors. Many of the pathogen and host physiological processes involved in the disease development have been established, but their importance in disease development and their underlying molecular mechanisms largely remain obscure. This chapter summarizes current knowledge on the physiological aspect of the pathogen-host interaction regarding genetic variation of pathogens, virulence determinants, and nature of host defenses. Practices and strategies to manipulate these processes to suppress and manage the disease are also discussed.
