Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

Cytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Evaluating black pod resistance in cocoa (Theobroma cacao L.) and its relationship with phenotypical and biochemical characteristics

Beverage Plant Research
Disease associated with Phytophthora is a great menace to cocoa. Chemical control measures are however proven to be ineffective. Hence, the most feasible and effective method to combat this situation is using resistant planting material as they are the ...

Phytophthora-ID.org: A Sequence-Based Phytophthora Identification Tool [PDF]

Plant Disease, 2011
Contemporary species identification relies strongly on sequence-based identification, yet resources for identification of many fungal and oomycete pathogens are rare. We developed two web-based, searchable databases for rapid identification of Phytophthora spp. based on sequencing of the internal transcribed spacer (ITS) or the cytochrome oxidase (cox)

Mechanophores for Mechano‐Imaging in Polymeric Materials

Helvetica Chimica Acta, EarlyView.
Mechanophore‐based mechanochromic systems convert mechanical forces in polymers into optical signals, enabling direct imaging of stress localization and molecular damage. This perspective highlights recent advances in mechanophore design and their use to probe local mechanics across diverse polymer matrices, and concludes by outlining opportunities for

High Diversity of Novel Viruses in the Tree Pathogen Phytophthora castaneae Revealed by High-Throughput Sequencing of Total and Small RNA

Frontiers in Microbiology, 2022
Phytophthora castaneae, an oomycete pathogen causing root and trunk rot of different tree species in Asia, was shown to harbor a rich diversity of novel viruses from different families. Four P. castaneae isolates collected from Chamaecyparis hodginsii in

Inline Oxygenation in Drip‐Irrigated Citrus: How Much Agrochemical Reduction Is Needed to Achieve Net Environmental Benefits?

Irrigation and Drainage, EarlyView.
ABSTRACT The agronomic benefits of oxygen‐enriched irrigation, such as improved root development, enhanced nutrient uptake, and reduced fertiliser and pesticide requirements, are well documented. However, incorporating oxygenation devices into fertigation systems increases energy demand and material use, thereby incurring additional environmental ...

Comparative analysis of Phytophthora genomes reveals oomycete pathogenesis in crops

Heliyon, 2021
The oomycete genus Phytophthora includes devastating plant pathogens that are found in almost all ecosystems. We sequenced the genomes of two quarantined Phytophthora species–P. fragariae and P. rubi.

Survival of Phytophthora alni,Phytophthora kernoviae, and Phytophthora ramorum in a simulated aquatic environment at different levels of pH [PDF]

FEMS Microbiology Letters, 2012
Phytophthora ramorum, Phytophthora alni, and Phytophthora kernoviae present significant threats to biosecurity. As zoosporic oomycetes, these plant pathogens may spread through natural waterways and irrigation systems. However, survival of these pathogens in aquatic systems in response to water quality is not well understood.
