Gene Expression and Structural Differences Underpinning Black and White Colouration in Spiders

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The presence of multiple color variants within a single population, known as color polymorphism, is a striking example of intraspecific phenotypic variation and a model for studying evolutionary processes. These processes depend on the underlying mechanisms such as the genes and pigments involved; but we currently lack such information for non‐

Psyllid Cysteine Cathepsins Directly Cleave the Outer Membrane Protein BamD of Citrus Huanglongbing Pathogen

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3989-4004, June 2026.
ABSTRACT Candidatus Liberibacter asiaticus (CLas), the causative agent of citrus Huanglongbing (HLB), is transmitted by Asian citrus psyllid, Diaphorina citri; however, the role of the insect's immune effectors in defending against CLas remains poorly understood. This study reveals that D.

Histone Acetylation Enhancing Host Melanization in Response to Parasitism by an Endoparasitoid Wasp

open access: yesInsects
Endoparasitoids are insects that develop within other insects, employing unique strategies to enhance their offspring’s survival. They inject polydnavirus and/or venom into their hosts along with eggs, effectively suppressing the host’s immune system ...
