  • Enhancement of cold tolerance in tomato plants by genetic engineering of glycinebetaine biosynthesis

    Creator:
    Park, Eung-Jun
    Abstract:
    Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant in plants. While GB can increase tolerance of tomato plants to salt and drought stresses, its effect on chilling tolerance has not been examined. To evaluate whether...

    Abstract:
    Past afforestation programs launched to promote private and community woodlots in rural Ethiopia have not been based on clear understanding of the incentives and constraints of smallholder farmers. This study investigated the characteristic differences between tree-growing and non-tree-growing farm households and identified factors influencing farmers’ tree-growing decisions from a farming...
