Frontiers of Agricultural Science and Engineering 2015, Volume 2, Issue 2,   Pages 101-114 doi: 10.15302/J-FASE-2015068

Abstract: Wheat stripe rust caused by f. sp. ( ) poses a great threat to wheat production worldwide. The rapid change in virulence of leads to a loss of resistance in currently resistant wheat cultivars, which results in frequent disease epidemics. Therefore, a major focus is currently placed on investigating the molecular mechanisms underlying this rapid variation of pathogenicity and coevolving wheat resistance. Limited by the lack of a system for stable transformation of and the difficulties in wheat transformation, it is not easy to generate deeper insights into the wheat- interaction using established genetic methods. Nevertheless, considerable effort has been made to unravel the wheat- interaction and significant progress is being made. Histology and cytology have revealed basic details of infection strategies and defense responses during wheat- interactions, identified cellular components involved in wheat- interactions, and have helped to elucidate their role in the infection process or in plant defense responses. Transcriptome and genome sequencing has revealed the molecular features and dynamics of the wheat- pathosystem. Extensive molecular analyses have led to the identification of major components in the wheat resistance response and in virulence. Studies of wheat- interactions have now entered a new phase in which cellular and molecular approaches are being used. This review focuses on the cellular biology of wheat- interactions and integrates the emerging data from molecular analyses with the histocytological observations.

Outline of Strip Rolling Technological Control Theory

Zhang Jinzhi

Strategic Study of CAE 2001, Volume 3, Issue 4,   Pages 46-55

Abstract:

Classical rolling theory, which is based on the law of the lowest resistance,the condition of constant volume and the condition of equal flow per second,has formed a fairly integrated rolling applied technology science system by means of experiment and deduction. This system reflects only the static law of rolling process,so it is necessary to control dynamic rolling process by drawing high and new technology such as cybernetics, information theory and computer science into the system.During the history of rolling theory, classical rolling theory based on mechanics took the lead before the establishment of spring equation, after that the rolling process control theory based on mechanics and cybernetics took precedence. In this paper,the concept of technological control theory is put forward. A new theory system, which is based on fundamental rolling technology control theory, is set up. Its main content included：the tension theory system in continuous rolling, which reflects the negative feedback effect of tension, is set up;disturbance survey problem is settled in gauge control process;shape theory system, which resembles gauge control theory,by defining dual parameter,is established.

Keywords： continuous rolling process control     tension in continuous rolling     gauge control     shape stiffness     spring equation for rolling mill     comprehensive equal reserves for load distribution
