Piper solmsianum C.DC., which is popularly known as pariparoba, is a shrub that measures 1-3 m in height and it inhabits areas with wet tropical soils. The objective of this study was to analyze the leaf and stem anatomy using light microscopy, scanning electron micrographs, and energy-dispersive X-ray spectroscopy in order to provide information for species identification. The anatomical profile showed the following main microscopic markers: hypostomatic leaf; hypodermis layer on both sides; pearl glands; biconvex midrib shape; five collateral vascular bundles in open arc with the central bundle larger than the others; circular stem shape; collateral vascular bundles arranged in two rings; sinuous sclerenchymatic sheath in the pith; secretory idioblasts; and starch grains in the mesophyll, in the ground parenchyma of the midrib, petiole, and in the stem; and six morphotypes of calcium oxalate crystals (styloids, cuneiform, tabular crystal rosettes, cuneiform crystal rosettes, elongated square dipyramids, as well as very elongated square dipyramids).

“…(Á lvarez et al 2016), but it seems not to be useful for M. glomerata galling cecidomyiids. The histochemical features of the galls herein studied are strictly related to the features of host plant (Milan et al 2006;Espindola Jr et al 2009;Almeida et al 2016), corroborating the idea that the galls are products of plant potentialities, and morphogenetic and chemical constraints imposed by the host plants are determinant in their structure (Moura et al 2008;Fleury et al 2015).…”

“…The shapes of epidermal cells in frontal view changed in the galls on leaf lamina, and this could be explained by the similar features of epidermal cells on the leaf veins, where the galls may be induced, or by the differential growth of the gall tissues (Isaias et al 2013). Additionally, only the uniseriate glandular trichomes were maintained in galls, while the capitate glandular trichomes were observed only (Almeida et al 2016), and the developmental causes of their absence in the galls must be further investigated.…”

Plant potentialities determine anatomical and histochemical diversity in Mikania glomerata Spreng. galls

Arthropod gall super-hosts have distinct developmental responses to each gall inducer species. The taxa and feeding habits of the gall inducers determine each gall's histological patterns, but the host plant imposes histological constraints on gall differentiation. Mikania glomerata Spreng. (Asteraceae) is a gall super-host, presenting at least six distinct gall morphotypes. The aim of current study was to evaluate how different species of Cecidomyiidae can manipulate the same host plant tissues, demonstrating the potentialities of M. glomerata under distinct external signaling. We compared M. glomerata anatomy and histochemistry in fusiform galls induced by Liodiplosis cylindrica (Gagné 2001) on petioles, globoid galls induced by L. spherica (Gagné 2001) on leaf laminae, and conic galls of Clinodiplosis sp. on leaf laminae as well as in non-galled leaves and petioles. Even though each gall presents several distinct features, they share anatomical and histochemical patterns, determined by the host plant potentialities. We found that the ground and dermal system tissues were manipulated differently by each inducer, generating distinct gall morphotypes. Alterations on epidermal cell shapes and suppression of the capitate glandular trichomes occured in all studied galls. We report for the first time the occurrence of nutritive cells containing starch in globoid galls. The anatomical diversity of the galls on M. glomerata seems to be more related to distinct differentiation pathways of the host plant than to the taxonomic relationships between the gall-inducing species.

Ocotea porosa (Nees & Mart.) Barroso, commonly known as "imbuia", "canela-imbuia" or "imbuiaamarela" in Brazil, is a tree of the Southern Atlantic Forest. The present study investigates the anatomy of leaf and stem, volatile oil chemistry, as well as cytotoxicity and insecticidal activities of the essential oil of O. porosa. Species identification was achieved by anatomy features, mainly due to paracytic and anomocytic stomata; non-glandular trichomes; biconvex midrib and petiole with a collateral open arc vascular bundle; presence of a sclerenchymatous layer, starch grains and crystal sand in the stem; and the presence of HIGHLIGHTS  The anatomy features were useful for identification of Ocotea porosa.  The major volatile compounds were α-pinene, β-pinene and bicyclogermacrene.  Essential oil of O. porosa was cytotoxic against McCoy, B16F10 and MCF7cell lines.  The cytotoxic mechanism might be related to apoptotic events.  Insert 1-4 highlights no longer than 85 characters.  Insert a highlight no longer than 85 characters.  Insert a highlight no longer than 85 characters. • Insert a highlight no longer than 85 characters.
