Synthetic studies on the spiroacetal moiety of stenocarpin, a metabolite of Diplodia maydis
The fungus Diplodia maydis, (synonym Stenocarpella maydis (Berk)) is worldwide one of the most important cob rot pathogens of maize. The isolation of stenocarpin, a metabolite toxic to ducklings, from maize cultures of D. maydis as the 4,6-0-diacetate derivative and its structure elucidation has …

Molecular studies on the taxonomy, host-associations and viruses of the Diplodia-like anamorphs of the Botryosphaeriaceae
… has been on the fungal complex referred to as Diplodia pinea sensu lato. These fungi are members of the Botryosphaeriaceae and studies have specifically concentrated on their taxonomy, host associations and mycovirus infections associated with them. Diplodia pinea sensu lato represents a …

Yield Loss Studies With Anthracnose Stalk Rot of Corn
… suspension of Colletotrichum graminicola or Diplodia maydis to estimate potential yield loss. Experiments were done from 1978-1980 with a second location and D. maydis inoculations added in 1979 and 1980. Treatments were compared to a water injected control, as an inoculation wound effect …

Analysis of a <i>Pinus Radiata</i> Seed Stock Field in the Native Año Nuevo Stand in California
… that the disease observed is actually caused by Diplodia pinea (Desm.) Kickx. Survival analysis showed that the effect of tree genetic origin was significant to its time to disease, and that spatial location in the plantation was also significant. Average nearest neighbor analysis showed disease …

Stenocarpella Maydis: Identification, Management, and Population Diversity
<p>Diplodia ear rot (DER) has been a persistent corn disease across the Midwest, and in recent years it has become an annual problem. The objectives of this study were to i) develop a molecular assay for the identification of Stenocarpella maydis, causal agent of DER, ii) evaluate the effect of …

Sources and Inheritance of Resistance to Anthracnose Stalk Rot of Corn
… has been successfully used to reduce loss due to Diplodia and Gibberella stalk rots of corn, but this resistance does not appear to be effective in controlling anthracnose stalk rot. Knowledge about available sources of resistance and how this resistance is inherited would aid plant breeders in …

Synthesis of Sphaeropsidin a Derivatives in a Search for Compounds Active Against Drug-Resistance Cancer
… extracted from different sources but mainly from Diplodia cupressi. SphA has shown anticancer activity by overcoming multidrug resistance as well as inducing apoptosis (cell programmed death) by causing marked and rapid irreversible cellular shrinkage. However, SphA has only shown, on average, …

A diallel study of stalk rot resistance in elite maize and its interaction with yield
… was a split-plot with two stalk rot pathogens (Diplodia maydis and Fusarium moniliforme) and a control being the three whole plots and the inbreds described above and their single cross hybrids being the sub-plots. Plots were inoculated with the pathogens approximately three weeks following …

Diversity of fungi associated with dieback of Ziziphus Mucronata in Limpopo Province, South Africa
… include Dothiorella (=Spencermartinsia), Diplodia, Botryosphaeria, Neofusicoccum, Fusarium, Diaporthe (=Phomopsis), Cytospora, Didymella (=Phoma) and Alternaria. Results obtained from this study showed the diversity of fungi associated with dieback of Z. mucronata in Limpopo Province. …

Diallel analysis of diplopodia ear rot resistance in maize and an assessment of the genetic variability of Stenocarpella maydis through isozyme analysis
Diplodia ear rot (DER) of maize (Zea mays L.) caused by the fungus, Stenocarpella maydis (Berk.) Sutton has increased in incidence in localized fields over the past decade. My research focused on screening for resistance by examining the development of DER following inoculations prior to flowering, …
