Abstract:
... Lettuce drop caused by Sclerotinia spp. is an economically important disease of lettuce (Lactuca sativa L.), and cultivars with resistance to mycelial infection by Sclerotinia sclerotiorum (Lib.) de Bary and S. minor Jagger as well as to S. sclerotiorum ascospores are needed. Assessing resistance in field experiments can be complicated by fast bolting or small stature lettuce lines that may escape ...

Abstract:
... Agronomic traits may become adversely affected when field crops are transformed with foreign genes which confer resistance to plant pathogens. Field testing of such transformed plant lines is necessary to determine if desirable yield components have been retained through the transformation and regeneration process. Thirty-four peanut lines, thirty-two of which are transgenic containing anti-fungal ...

Abstract:
... Sclerotinia minor Jagger is the causal agent of Sclerotinia blight, a highly destructive disease of peanut (Arachis hypogaea). Based on evidence that oxalic acid is involved in the pathogenicity of many Sclerotinia species, our objectives were to recover transgenic peanut plants expressing an oxalic acid-degrading oxalate oxidase and to evaluate them for increased resistance to S. minor. Transform ...

Abstract:
... Despite extensive germplasm screening, no lettuce accessions have been identified as possessing immunity to infection by Sclerotinia species. As previously reported, several genotypes have consistently shown a significant reduction in disease incidence compared with susceptible varieties following inoculation with S. minor. Many of these genotypes exhibit architectural features that may promote av ...

Abstract:
... Incidence of the disease lettuce drop caused by Sclerotinia minor is often high in California lettuce fields despite the use of cultural and chemical controls. Development of resistant lettuce cultivars has been hindered by the difficulty of evaluating resistance in field tests and the lack of a screening procedure that reliably predicts field performance. Several lettuce genotypes of diverse geog ...
