    The NSm of tomato spotted wilt virus is an elicitor of RTSW-mediated virus resistance in tobacco and its ability in HR induction is dissociated of movement function

    HUANG Changjun; LIU Yong; YUAN Cheng; ZENG Jianmin; YU Haiqin; GAO Yulonng; XIAO Bingguang
    Yunnan Academy of Tobacco Agricultural Sciences of CNTC, Kunming City, Yunnan Province, P.R. China
    Tomato spotted wilt virus (TSWV, order Bunyavirales, family Tospoviridae and genus Orthotospovirus) is one of the most destructive viral pathogens of plants. Recently, a single dominant gene conferring complete resistance to TSWV (RTSW) was found in a ...

    Study on absorption and transport of potassium (K) by foliar application in tobacco leaves

    DENG Xiaopeng; GAO Shudi; CHEN Yahua
    Yunnan Academy of Tobacco Agricultural Sciences of CNTC, Kunming City, Yunnan Province, P.R. China
    Effects of the foliar fertilizer on the uptake of potassium (K), as well as translocation and distribution among different position of tobacco leaf were studied under lack of K conditions. In order to study the suitable contents and the critical value of ...
