• Premise of the study: The term colleter is applied to trichomes or emergences positioned close developing vegetative and floral meristems that secrete a sticky, mucilaginous, and/or lipophilic exudate. Several ecological functions are attributed these glands, but none exclusive colleters. Patterns morphology distribution colleters may be valuable for systematics phylogeny, especially concerning problematic large groups such as subtribe Pleurothallidinae, also essential understand evolution...
Nectar gain and loss are important flower transitions observed in angiosperms, particularly common orchids. To understand such transitions, the availability of detailed anatomical data species-level phylogenies crucial. We investigated evolution food deception Epidendrum, one largest orchid genera, using genus phylogeny to map between nectar among different clades. Associations histochemical changes were examined fresh material available from 27 species. The presence/absence Epidendrum...
The investigation of reproductive barriers between sister species can provide insights into how new lineages arise, and integrity is maintained in the face interspecific gene flow. Different pre- postzygotic limit exchange sympatric populations, different sources evidence are often required to investigate role multiple isolation (RI) mechanisms.We tested hypothesis hybridization potential introgression Epidendrum secundum xanthinum, two Neotropical food-deceptive orchid species, using...
Here, we proposed that volatile organic compounds (VOC), specifically methyl salicylate (MeSA), mediate the formation of calcium oxalate crystals (COC) in defence against ozone (O3) oxidative damage. We performed experiments using Croton floribundus, a pioneer tree species is tolerant to O3 and widely distributed Brazilian forest. This constitutively produces COC. exposed plants controlled fumigation experiment assessed biochemical, physiological, morphological parameters. induced...
Passiflora species presents a coevolutive relationship with Heliconiini butterflies, their primary herbivores. The caterpillars are able to detoxify toxic compounds produced by Passiflora, thus morphological defense strategies stand out over chemical innovations. In this framework, we highlight the presence of mimetic structures and extrafloral nectaries (EFN) as strategies. Heliconian butterflies oviposit only on leaves that do not possess previous eggs, so egg mimics could prevent...
Abstract Reabsorption is a phase of nectar dynamics that occurs concurrently with secretion; it has been described in floral nectaries exude through stomata or unicellular trichomes, but not yet recorded extrafloral glands. Apparently, reabsorption does occur multicellular secretory trichomes ( MST ) due to the presence lipophilic impregnations – which resemble Casparian strips anticlinal walls stalk cells. It assumed these restrict solute movement within unidirectionally and exclusively by...
Microscopic studies on isolated ozone (O3) effects or those in synergy with light stress commonly report the induction of polyphenols that exhibit different aspects within vacuole photosynthesizing cells. It has been assumed these are randomly spread symptomatic (injured) regions leaf blade. Interestingly, secretory ducts constitutively produce also same variations their vacuolar aspect, a spatial sequence related to destiny cells (e.g., programmed cell death (PCD) lytic secretion...
Connective glands are important morphological characters for the taxonomy of some genera Malpighiaceae, with few recent studies having just elucidated these glands' anatomical and ecological functions. In order to test systematic relevance connective currently accepted phylogenetic informal clades we characterised anatomy and/or histochemistry two-thirds Malpighiaceae ten species from nine families Malpighiales test: 1. Do occur in flowers all Malpighiaceae?; 2. Are they taxonomically...
The present study describes the occurrence of mucilage ducts within Polygalaceae. Polygala angulata DC. is a species from Brazilian cerrado that possesses secretory in stem angles primary growth. First, schizogeneous process and later, lytic both take place course duct formation, characterizing development glands as schizolysigenous. Histochemical tests confirm nature exudate. presumable functions this gland are associated with xeromorphic adaptation to environment.
