Abstract
Galls are neoformed structures induced by specific animals, fungi, bacteria, virus or some parasitic plants on their host plant organs. Developmental processes are well known in Agrobacterium tumefasciens galls, but the animal-induced galls have a striking anatomical diversity, concerning several patterns, which were reunited herein. Anatomical traits observed in animal-induced galls involve manipulation of plant morphogenesis in convergent ways. Nematode, mite and insect galls usually contain homogeneous storage parenchyma and develop due to hyperplasia and cell hypertrophy. The development of typical nutritive tissues, giant cells, or hypertrophied vascular bundles may occur. Some other anatomical features may be usually restricted to galls induced by specific taxa, but they may eventually be related to the developmental potentialities of the host plants. The combination of distinct morphogenetic peculiarities in each gall system culminates in extant gall structural diversity. Convergent anatomical traits are observed according to the feeding mode of the gall inducers, representing potentiation or inhibition of similar events of host plant morphogenesis and cell redifferentiation, independent of gall-inducing taxa.

Mechanisms of hydraulic conductivity in the leaf galls of Meunieriella sp. (Cecidomyiidae) in Avicennia schaueriana (Acanthaceae): does vascularization explain the preferential sites of induction?

TL;DR: In this paper , the preferential sites of gall induction were the midribs and secondary veins at the basal leaf third, where the galls were expected to grow largest, and if the vascular system in galls and adjacent regions was altered to favor water supply in gall, increasing their growth.

TL;DR: In this paper , the influence of different light conditions on infestation rates, establishment, and morphogenesis of gall-inducing insects is examined on leaves of Eugenia uniflora L. (Myrtaceae).

The adaptive significance of insect gall morphology

TL;DR: It is suggested that the hypothesis that selection imposed by enemies remains the most probable adaptive explanation for the evolution of diversity in insect galls has yet to be tested explicitly, and the requirements for an appropriate cross-species analysis are discussed.

Adaptive Nature of Insect Galls

TL;DR: The evolution of the galling habit has followed two pathways, one via mining plant tissues and the other from sedentary external herbivores that then modify plant growth.

Plant traits that predict resistance to herbivores

TL;DR: The hypothesis that herbivores select most strongly on genetic variation in life-history, morphological and physical resistance traits, but the greater pleiotropic effects of genes controlling these traits impose strong constraints on their evolution is proposed.
