  • Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

    Creator:
    Wang, Yueju
    Abstract:
    The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

  • Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

    Creator:
    Ding, Pinghai
    Abstract:
    Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...
