Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

open access: yesCytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

Host-plant species conservatism and ecology of a parasitoid fig wasp genus (Chalcidoidea; Sycoryctinae; Arachonia).

open access: yesPLoS ONE, 2012
Parasitoid diversity in terrestrial ecosystems is enormous. However, ecological processes underpinning their evolutionary diversification in association with other trophic groups are still unclear. Specialisation and interdependencies among chalcid wasps

Towards a Biodiversity Positive Business Strategy: The MCRV (Monitoring, Conserving, Restoring, Valorizing) Framework

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite mounting regulatory pressure and growing scientific consensus on biodiversity loss, most corporate action remains reactive, fragmented, and strategically peripheral. Existing frameworks address what firms should report rather than how they can build the organizational capabilities required to act strategically.

The complete chloroplast genome of two related fig species Ficus squamosa and Ficus heterostyla

open access: yesMitochondrial DNA. Part B. Resources, 2022
The Ficus squamosa and Ficus heterostyla share an undescribed pollinating fig wasp Ceratosolen sp. in Xishuangbanna region, which constitutes the most excellent model to study the role of convergent evolution and hybridization in the species-specific fig-

Pollinator risks and recovery from air pollutant interactions during the fossil‐fuel transition

open access: yesFrontiers in Ecology and the Environment, EarlyView.
By altering the composition and concentration of floral scents, air pollutants such as ozone (O3) and nitrogen oxides (NOx) disrupt the ability of insect pollinators to locate flowers, threatening biodiversity and crop production. We examine the impact of these pollutants on pollinator performance and evaluate the short‐ and long‐term consequences of ...

Polyembryonic or Apomictic Seeds Enable Fig Trees to Establish New Populations Without Their Pollinating Wasps, a Case Observation in Ficus gasparriniana

open access: yesEcology and Evolution
Fig–wasp coevolution has been extensively studied as a fascinating case of extreme plant–insect codiversification, yet little is known about how fig trees reproduce without pollinating fig wasps. This study provides direct evidence that fig trees sustain

The Phylosymbiosis Pattern Between the Fig Wasps of the Same Genus and Their Associated Microbiota

open access: yesFrontiers in Microbiology, 2022
Microbial communities can be critical for many metazoans, which can lead to the observation of phylosymbiosis with phylogenetically related species sharing similar microbial communities.

First record of the non-pollinating fig wasp Odontofroggatia galili Wiebes, 1980 from Malta (Hymenoptera, Chalcidoidea, Agaonidae) [PDF]

open access: yes, 2010
The fig wasp Odontofroggatia galili is reported for the first time from Malta. Odontofroggatia is a non-pollinating fig wasp genus associated with a narrow range of host plant species, among them Ficus microcarpa, a widespread ornamental tree native to ...

Domesticated bacterial origin genes regulate homeostasis of the insect gut microbiome and empower adaptation

open access: yesiMeta, EarlyView.
Horizontal gene transfer introduced bacterial CDC genes into the leafhopper genome, providing genetic material for subsequent evolutionary innovation. Different CDC copies diversified at the sequence, structural, and functional levels. RdCDC3 retained its ancestral pore‐forming activity and was recruited for egg defense, whereas RdCDC9 lost its ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius
