摘 要：Wheat powdery mildew, caused byBlumeria graminis ***(Bgt), is one of the most prevalent diseases of wheat worldwide and can lead to severe yield *** genes involved in powdery mildew resistance will be useful for disease resistance breeding and *** is a member of a multigene family widely found in higher plants and is associated with a variety of plant physiological functions and defense ***, the role of CRT in wheat resistance to powdery mildew remains ***3 was identified from the proteomic sequence of an incompatible interaction between the wheat(Triticum aestivum) cultivar Xingmin 318 and the Bgt isolate *** analysis of transient expression of the GFP-TaCRT3 fusion protein in Nicotiana benthamiana leaves,TaCRT3 was found to be located in the nucleus, cytoplasm and cell *** expression levels of TaCRT3 were significantly upregulated in the wheat —Bgt incompatible *** critically,knockdown of TaCRT3 using virus-induced gene silencing( VIGS) resulted in attenuated resistance to Bgt in *** analysis showed a significant increase in Bgt development in TaCRT3-silenced plants, whereas pathogen-related(PR) protein was significantly downregulated in TaCRT3-silenced *** addition, overexpression of TaCRT3 in wheat enhanced the resistance to powdery mildew, the growth of Bgt was significantly inhibited, and the area of H O near the infection site and the expression of defense-related genes of the salicylic acid(SA) pathway significantly *** findings imply that TaCRT3 may act as a disease resistance factor that positively regulates resistance to powdery mildew,during which SA signaling is probably activated.
