Gall responses to drying habitats: Insights from the community of galling herbivores associated with the superhost Caryocar brasiliense Cambess. (Caryocaraceae)

open access: yesPlant Biology, EarlyView.
Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

open access: yesPlant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

Abstract A new morphologically divergent genus and species of Euphorbiaceae from the Democratic Republic of the Congo, Ewangoa cardiophora, is described and illustrated. This taxon is easily recognised by its leaf‐opposed inflorescences, which are surrounded by a single cordiform involucral bract. Molecular phylogenetic evidence shows that Ewangoa is a
