Influence of Altitudes on Sporangia Size and Aggressiveness of Phytophthoracolocasiae Isolates in Cameroon [PDF]

, 2014
A study was carried out in four altitudes in Cameroon to assess the size of the sporangia and the aggressiveness of Phytophthoracolocasiae isolates on taro cultivars.

Rapid Determination of Phytophthora infestans sporangia Using a Surface Plasmon Resonance Immunosensor

, 2007
Phytophthora infestans is the cause of late blight disease in potato and is an economically important pathogen worldwide. Early disease detection is important to implement disease control measures.

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

Pest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.

Effect of spore density, cultivar resistance and Phytophthora infestans isolate on tuber blight under field conditions [PDF]

, 2010
Survival of P. infestans in soil was limited to 5 weeks at high inoculum density. With a ten fold dilution of the infection pressure survival of P. infestans in soil was limited to two weeks.

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

In vitro biocontrol potential of plant extract-based formulation against infection structures of Phytophthora infestans along with lower non-target effects

Frontiers in Microbiology
Late blight, caused by Phytophthora infestans, is among the most destructive diseases affecting tomatoes and potatoes. The use of synthetic fungicides is becoming increasingly restricted due to the banning of several active ingredients for environmental ...

Studies in the genus Riccia (Marchantiales) from southern Africa. 27. Riccia lanceolata and R. radicosa now also locally reported

Bothalia: African Biodiversity & Conservation, 2004
Riccia lanceolata and R. radicosa are newly reported from southern Africa. Riccia lanceolata is quite widespread in sub-Saharan Africa, whereas R. radicosa has only been collected once before, namely in the Democratic Republic of the Congo (Zaire).

Lithochloron, a new genus of green algae residing in coral skeleton (Cladophorales, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Coral skeletons host diverse microbial communities, including endolithic green algae that contribute to holobiont functioning. The siphonous green alga Ostreobium (Bryopsidales) is arguably the best‐known coral endolith, but recent environmental sequencing has indicated that other lineages of green algae may also inhabit the coral skeleton ...
