Competition for waterborne food resources among tropical shallow-water sponges. [PDF]

open access: yesEcology
Abstract A recurrent theme in marine ecology is that the community dynamics of sessile, suspension‐feeding animals is primarily limited by the availability of space, but in some habitats, filtration by these organisms may locally deplete water column resources, setting the stage for exploitative competition for food.

Complete Mitochondrial Genome Sequencing of Asian Glass Lizards (Anguidae: <i>Dopasia</i>): Comparative Analysis With Limbless Anguids and New Insights Into the Adaptive Evolution of Protein-Coding Genes. [PDF]

open access: yesEcol Evol
This study analyzed mitochondrial genomes from eight individuals of two Dopasia species and 28 other Anguidae sequences to investigate selection patterns in protein‐coding genes. Positive selection was detected in six of the 13 mitochondrial genes, with amino acid preferences correlating with geographic distribution, suggesting a role in environmental ...

Comparative Genomics and Phylogenetic Analyses of <i>Aquarius macrophyllus</i> and Related Genera in Alismataceae Based on Plastome Data. [PDF]

open access: yesEcol Evol
We sequenced the plastome of Aquarius macrophyllus and conducted a comparative analysis incorporating eight species from four related genera in Alismataceae. Phylogenetic analysis of Alismataceae elucidated that Alisma and Burnatia species were early diverged, followed by Hydrocleys and Limnocharis. The monophyly of Aquarius and its sister relationship

Stagonosporopsis cucurbitacearum Effector Protein ScAA9 Contributes to Virulence and Triggers Plant Immune Responses. [PDF]

open access: yesMol Plant Pathol
The AA9 family protein ScAA9 of Stagonosporopsis cucurbitacearum plays dual roles as both a virulence factor for infection and a PAMP for host immune manipulation, highlighting the complexity of S. cucurbitacearum–host interactions. ABSTRACT Fungal pathogens secrete cell wall‐degrading enzymes that either act as virulence factors or are perceived by ...
