“…In addition, they have high market acceptance due to exuberance and post-harvest durability (SILVA et al, 2014). The variety of colors and shapes gives them significant ornamental potential and consequent economic importance, making these plants a target of predation (PALHA et al, 2018), which impacts population distribution and creates risk of extinction.…”

MODULATION OF CULTURE MEDIUM ON THE EX SITU CONSERVATION OF Neoregelia mucugensis Leme (BROMELIACEAE)1

Bromeliads are the target of predatory extractivism and consequently many species are included in the red list of threatened species, such as those belonging to the genus Neoregelia. Although Neoregelia mucugensis has not been evaluated for the degree of threat, its exploitation is exclusively extractive and its occurrence in Chapada Diamantina-BA is subject to the action of fires that affect the region annually. In this context, applying techniques aimed at protecting this genetic resource is fundamental for both the maintenance of its natural populations and the ex situ conservation of this genetic material. Plant tissue culture techniques have been successfully applied for the conservation of several bromeliad species. One of the methods used is slow growth, which consists in reducing plant metabolism and consequently decelerating its growth, which allows the maintenance of in vitro plant collections without the need for subculture. In this context, the objective of this study was to test the reduction of salts in the culture medium and the addition of osmoregulators on the induction of slow growth of N. mucugensis. Plants were subjected to treatments composed of different concentrations of MS medium and mannitol for a period of 12 months, when then analyses were conducted to evaluate growth, chlorophyll content and regeneration capacity of shoots in vitro. It was found that the treatment containing MS ½ and 7.8 g.L-1 of mannitol is indicated for in vitro conservation of N. mucugensis with maintenance of the regenerative capacity of its tissues.

The knowledge of the geographical distribution of fungi is essential to promote the understanding of global and national fungal diversity patterns. In this study, we provide a literature-based checklist of Aspergillus, Penicillium, and Talaromyces species recorded in the biomes of the Brazilian Atlantic Forest and the Brazilian Pampa. Only Penicillium digitatum was reported for the Pampa biome. For the Atlantic Forest, a total of 169 species (68 Aspergillus, 79 Penicillium, and 22 Talaromyces) are reported, of which 20 are typified with specimens from this biome, including the novel species Penicillium nordestinense (section Lanata-Divaricata) that is described in this study. Penicillium nordestinense is phylogenetically related to the invalidly described species Penicillium setosum, and this species is validated here. Soil was the most common substrate from where species were reported. Several reported species are well known in biotechnological processes. Penicilliopsis zonata and Sclerocleista ornata, species previously treated in Aspergillus, are recorded. This checklist reflects the limited knowledge of fungal species in tropical environments, such as the Brazilian Atlantic Forest and Pampa biomes. This information is a good framework for understanding the Brazilian diversity of Aspergillus, Penicillium, and Talaromyces and provides data for future fungal biogeographical studies in tropical environments.
