Diverse sources of infection and cryptic recombination revealed in South African Diplodia pinea populations.
This study considers the population diversity and structure of Diplodia pinea in South Africa at different spatial scales from single trees to plantations, as well as comparing infections on healthy and diseased trees. A total of 236 isolates were characterized using 13 microsatellite markers. Analysis of these markers confirmed previous results that D. pinea has a high level of gene and genoty...
متن کاملAustrian pine phenolics are likely contributors to systemic induced resistance against Diplodia pinea.
The molecular basis of the systemic induced resistance (SIR) phenotype known to occur in Austrian pine (Pinus nigra J.F. Arnold) in response to the tip blight and canker pathogen Diplodia pinea (Desm.) remains unclear. Specialized metabolites such as phenolics are considered to be an important component of plant defense, including SIR, but the antimicrobial activity of many of these putative de...
متن کاملSources of Diplodia pinea endophytic infections in Pinus patula and P. radiata seedlings in South Africa
Diplodia pinea, an opportunistic and latent pathogen, can significantly affect Pinus productivity worldwide. Despite being studied in South Africa for almost 100 years, the source of D. pinea inoculum responsible for seedling infection is unknown. The aim of this study was to determine the role of seed in vertical transmission of D. pinea and to investigate sources of inoculum leading to horizo...
متن کاملHigh-resolution melting analysis: a new molecular approach for the early detection of Diplodia pinea in Austrian pine.
The differentiation of Diplodia pinea from closely related species, such as Diplodia scrobiculata and Diplodia seriata, and its detection in plant tissue, represented a critical issue for a long time. Molecular screening tools have recently been developed to address this topic. In this study we applied one of the most sensitive and rapid diagnostic screening method so far developed, called High...
متن کاملMAT gene idiomorphs suggest a heterothallic sexual cycle in a predominantly asexual and important pine pathogen.
Diplodia pinea (=Sphaeropsis sapinea) is a well-known and economically important latent pathogen of Pinus spp. in many parts of the world. Despite intensive scrutiny, its sexual state has never been observed and the fungus has thus been considered exclusively asexual. It was, therefore, surprising that a recent population genetics study showed high genotypic diversity and random association of ...
