Infection Efficiency of Four Phytophthora infestans Clonal Lineages and DNA-Based Quantification of Sporangia. [PDF]

open access: yesPLoS ONE, 2015
The presence and abundance of pathogen inoculum is with host resistance and environmental conditions a key factor in epidemic development. Therefore, several spore-sampling devices have been proposed to monitor pathogen inoculum above fields. However, to

Survival potential of Phytophthora infestans sporangia in relation to environmental factors and late blight occurrence [PDF]

open access: yesJournal of Plant Protection Research, 2016
Potato is an important crop globally and late blight (Phytophthora infestans) often results in severe crop loss. The cost for late blight control can be in excess of $210 million in the United States.

Indehiscent sporangia enable the accumulation of local fern diversity at the Qinghai-Tibetan Plateau [PDF]

open access: yesBMC Evolutionary Biology, 2012
Background Indehiscent sporangia are reported for only a few of derived leptosporangiate ferns. Their evolution has been likely caused by conditions in which promotion of self-fertilization is an evolutionary advantageous strategy such as the ...

A Weather-Driven Model for Predicting Infections of Grapevines by Sporangia of Plasmopara viticola [PDF]

open access: yesFrontiers in Plant Science, 2021
A mechanistic model was developed to predict secondary infections of Plasmopara viticola and their severity as influenced by environmental conditions; the model incorporates the processes of sporangia production and survival on downy mildew (DM) lesions,

Production and Release of Asexual Sporangia in Plasmopara viticola [PDF]

open access: yesPhytopathology®, 2013
To study the influence of environmental conditions on sporulation of Plasmopara viticola lesions under vineyard's conditions, unsprayed vines were inspected every second or third day and the numbers of sporulating and nonsporulating lesions were counted in two North Italy vineyards in 2008 to 2010.

Influence of environmental factors on germination of Plasmopara viticola sporangia sourced from mediterranean Western Australia [PDF]

open access: yesPhytopathologia Mediterranea, 2007
Direct germination via the production of a germ tube was demonstrated in the absence of the host for Plasmopara viticola (causal agent of grape downy mildew) sporangia sourced from a major grape production area in mediterranean Western Australia (WA). In

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Novel Mucor species (Mucoromycetes, Mucoraceae) from northern Thailand [PDF]

open access: yesMycoKeys, 2021
Mucor species are common fast-growing fungi found in soil. Two new species of Mucor and one new geographical record of M. nederlandicus were collected from northern Thailand and are described in this study.
