| transgenic carrots with enhanced resistance against two major pathogens, erysiphe heraclei and alternaria dauci. | in vitro assay indicated that the human lysozyme has lytic activity against phytopathogenic fungi and bacteria. a human lysozyme gene was placed under control of the constitutive camv 35s promoter and the resulting expression plasmid was introduced into two cultivars (cv.) of carrot, kurodagosun (k5) and nantes scarlet (ns), by agrobacterium tumefaciens-mediated method. seven and fourteen transgenic plants of cv. k5 and cv. ns were regenerated, respectively, and the obtained transgenic carrots o ... | 2000 | 10717319 |
| broad-spectrum disease resistance to necrotrophic and biotrophic pathogens in transgenic carrots (daucus carota l.) expressing an arabidopsis npr1 gene. | the development of transgenic plants highly resistant to a range of pathogens using traditional signal gene expression strategies has been largely ineffective. modification of systemic acquired resistance (sar) through the overexpression of a controlling gene such as npr1 (non-expressor of pr genes) offers an attractive alternative for augmenting the plants innate defense system. the arabidopsis (at) npr1 gene was successfully introduced into 'nantes coreless' carrot under control of a camv 35s ... | 2009 | 19859731 |
| [disease survey and pathogen identification on notopterygium incisum in gansu province]. | six diseases have been found after disease surveys on notopterygium incisum in gansu province during 2004 to 2007. they were brown spot (ascochyta levistici), powdery mildew (erysiphe heraclei), grey spot (alternaria sp. ; alternaria burnsii), leaf spot (septoria dearnessii), angular leaf spot (pleospora sp.), leaf streak (phoma sp.), bacterial angular leaf spot and a virus disease. bacterial angular leaf spot and powdery mildew are the urgent problems waiting to be solved effectively. all these ... | 2009 | 19894529 |
| biodiversity and new records of microfungi in the ruhrarea (north rhine westfalia), germany. | during our investigations of the microflora in nrw (duisburg, düsseldorf and essen incl. the greenhouse of the botanical garden) in 2007 and 2008, we were able to collect and identify about 55 species on trees, bushes and ornamental plants as parasites and saprophytes. some of these species are new for germany or have been only rarely found until now. most of the species belong the ascomycotina, basidiomycotina and deuteromycotina for example arthrocladiella mougeotii (lév.) vassilkov. on lycium ... | 2009 | 20222564 |
| enhanced disease resistance in transgenic carrot (daucus carota l.) plants over-expressing a rice cationic peroxidase. | plant class iii peroxidases are involved in numerous responses related to pathogen resistance including controlling hydrogen peroxide (h(2)o(2)) levels and lignin formation. peroxidases catalyze the oxidation of organic compounds using h(2)o(2) as an oxidant. we examined the mechanisms of disease resistance in a transgenic carrot line (p23) which constitutively over-expresses the rice cationic peroxidase osprx114 (previously known as po-c1) and which exhibits enhanced resistance to necrotrophic ... | 2010 | 20730544 |
