Cover Story: Cynipid gall wasps redirect plant development to form highly specialised organs that shelter and nourish their larvae. We investigated how Andricus quercustozae manipulates axillary buds of Quercus virgiliana across four stages of gall formation. Histology revealed sustained hyperplasia, vascular redirection, and progressive lignification, generating a complex, self-contained structure. An exploratory transcriptomic comparison showed suppression of photosynthesis and modulation of developmental and metabolic pathways, supporting a shift from assimilatory tissue to a nutrient sink. Together, these findings provide a framework for future stage-resolved analyses and position Q. virgiliana as a model to unravel the molecular mechanisms underlying the extended phenotype and insect–plant co-evolution in Mediterranean forests.

Oxalis tuberosa (oca) is a tuber crop native to the Andes, valued for its nutrition but understudied genetically. Its strict short-day (SD) tuberization suggests a photoperiodic control mechanism similar to that of potato, where an FT-like protein ac...
