Journal ArticleDOI
Illustrated and annotated checklist of Brazilian gall morphotypes.
Rosy Mary dos Santos Isaias,Renê Gonçalves da Silva Carneiro,Denis Coelho de Oliveira,Jean Carlos Santos +3 more
TL;DR: This checklist of the Brazilian gall morphotypes proposes seven standardized morphotypes and five additional shapes that group the majority of the three-dimensional shapes reported in literature, and Criteria are proposed to standardize the terminology.
Journal ArticleDOI
Redifferentiation of leaflet tissues during midrib gall development in Copaifera langsdorffii (Fabaceae)
TL;DR: The largest impact of the cecidomyiid feeding action occurred in gall tissues redifferentiated from protoderm and adaxial ground meristem, which provided advantages to the gall maker of the C. langsdorffii midrib gall in terms of nutritional value, microenvironment, and protection against natural enemies.
Journal ArticleDOI
Cytological and histochemical gradients induced by a sucking insect in galls of Aspidosperma australe Arg. Muell (Apocynaceae)
TL;DR: The cytological and histochemical gradients validate the storage of starch as a pattern in galls induced by sucking insects in the Neotropical region and the detection of enzymes related to carbohydrate metabolism and sites of ROS production is described for the first time.
Journal ArticleDOI
Is the oxidative stress caused by Aspidosperma spp. galls capable of altering leaf photosynthesis
Denis Coelho de Oliveira,Rosy Mary dos Santos Isaias,Ana Silvia Franco Pinheiro Moreira,Thiago Alves Magalhães,José P. Lemos-Filho +4 more
TL;DR: The occurrence of numerous large plastoglobules in the galled tissues seemed to be related to oxidative stress and to the recovery of the thylakoid membrane systems, and the maintenance of the ETR(MAX) values indicated the existence of an efficient strategy to maintain similar photosynthesis rates in galled and non-galled tissues.
Journal ArticleDOI
Do cecidomyiidae galls of Aspidosperma spruceanum (Apocynaceae) fit the pre-established cytological and histochemical patterns?
Denis Coelho de Oliveira,Thiago Alves Magalhães,Renê Gonçalves da Silva Carneiro,Marina Neiva Alvim,Rosy Mary dos Santos Isaias +4 more
TL;DR: Phosphorylase, glucose-6-phosphatase, acid phosphatases, invertases, and sucrose synthase activities were detected for the first time, in the Neotropical region, and discussed in relation to gall maintenance and the feeding activity of the Cecidomyiidae.
