DOI: 10.1002/ps.6119
Abstract: BACKGROUND The significance of morphological responses of hosts on susceptibility against gall-inducing insects are relatively unknown specially in planted forests. Here, we investigate the temporal morphological responses (gall development) induced by the invasive gall wasp… read more here.

DOI: 10.1007/s00425-017-2778-5
Abstract: AbstractMain conclusionExtensive de novo vascularization of leafy galls emerging uponRhodococcus fasciansinfection is achieved by fascicular/interfascicular cambium activity and transdifferentiation of parenchyma cells correlated with increased auxin signaling. A leafy gall consisting of fully developed yet… read more here.

DOI: 10.1007/s00425-018-2926-6
Abstract: Main conclusionThe weevil gall contains two distinct regions, differing in hydrolytic and antioxidant enzymes activity and profiles, which is also functionally distinct from the non-infected Cuscuta stems.Weevils of the genus Smicronyx are gall-forming insects, widely… read more here.

The gall wasp Leptocybe invasa (Hymenoptera: Eulophidae) stimulates different chemical and phytohormone responses in two Eucalyptus varieties that vary in susceptibility to galling
Sign Up to like & getrecommendations! Published in 2017 at "Tree Physiology"
DOI: 10.1093/treephys/tpx098
Abstract: Gall-inducing insects produce various types of galls on plants, but little is known about the gall-induction mechanism of these galling insects. The gall wasp Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) forms galls of different… read more here.

DOI: 10.1093/zoolinnean/zlad009
Abstract: Petrarca is an ascothoracidan endoparasite in scleratinian dendrophyllid corals. Petrarca can stimulate coral growth, forming a gall chamber to house itself inside the coral skeleton. The diversity, molecular phylogeny and feeding ecology of Petrarca are… read more here.
