“…Micropropag., 16:e156, 2020 Andrade et al (2000) evaluated the in vitro multiplication of M. urundeuva and observed a highest number of shoots for 1.0 mg L -1 BAP, so that most of the shoots developed in a single bud, which confirm our results. Similar results were observed by Paiva and Aloufa (2009) with Schinus terebinthifolius; however, there was two shoots in each nodal segment. The organogenesis of shoots in all concentrations of BAP, including in the absence of this growth regulator, may indicate that endogenous cytokinins induce apical and cotyledonary shoots, considering this hormone are synthetized in the roots and transported in the xylem vessels (Ishibashi et al, 2017;Bezerra et al, 2014).…”

Myracrodruon urundeuva is a native tree species that stands out for the use of its wood and for medicinal purposes. Due to the multiple uses and extractive exploitation, this species has been threatened with extinction. Thus, it is important to develop strategies in order to ensure conservation and long-term exploitation. This work aimed to establish a protocol of in vitro seed germination and micropropagation of M. urundeuva. Different support agents (vermiculite and agar) and presence of sucrose were tested for in vitro germination, while different concentrations of BAP (0.0, 0.5, 1.0, and 2.0 mg L-1) and explant types (apical and cotyledonary nodes) were tested for multiplication. The use of vermiculite as a support agent favored in vitro germination of M. urundeuva, with germination percentage of 64.3% and 32% for vermiculite and agar, respectively. No significant differences were observed for the different BAP concentrations tested in multiplication and the treatment with 1.0 mg L-1 BAP presented higher values for most variables analyzed. Cotyledonary explants presented higher number of shoots (1.6 shoots) compared to the apical ones (1.1 shoots). Vermiculite may be used as a replacement for agar for in vitro seed germination and the combination of 1.0 mg L-1 BAP and cotyledonary explants may be used for in vitro multiplication of M. urundeuva. Furthermore, studies are needed to improve in vitro multiplication methods of this species.

“…Seeds were washed by keeping them for 30 min in flasks under running tap water, then surface sterilized inside a laminar flow chamber with 70% ethanol for 1 min and 5% sodium hypochlorite (NaOCl) for 10 min followed by rinsing thrice with autoclaved distilled water. The seeds were incubated in concentrated sulfuric acid for 15–20 min followed by rinsing thrice in autoclaved distilled water ( Souza Filho et al, 2001 ; Paiva and Aloufa, 2009 ). Subsequently, the seeds were cultured in agar-solidified Murashige and Skoog (MS) medium ( Murashige and Skoog, 1962 ) containing 3% sucrose for germination.…”

A Model for Trans-Kingdom Pathogenicity in Fonsecaea Agents of Human Chromoblastomycosis

et al. 2018

The fungal genus Fonsecaea comprises etiological agents of human chromoblastomycosis, a chronic implantation skin disease. The current hypothesis is that patients acquire the infection through an injury from plant material. The present study aimed to evaluate a model of infection in plant and animal hosts to understand the parameters of trans-kingdom pathogenicity. Clinical strains of causative agents of chromoblastomycosis (Fonsecaea pedrosoi and Fonsecaea monophora) were compared with a strain of Fonsecaea erecta isolated from a living plant. The clinical strains of F. monophora and F. pedrosoi remained concentrated near the epidermis, whereas F. erecta colonized deeper plant tissues, resembling an endophytic behavior. In an invertebrate infection model with larvae of a beetle, Tenebrio molitor, F. erecta exhibited the lowest survival rates. However, F. pedrosoi produced dark, spherical to ovoidal cells that resembled muriform cells, the invasive form of human chromoblastomycosis confirming the role of muriform cells as a pathogenic adaptation in animal tissues. An immunologic assay in BALB/c mice demonstrated the high virulence of saprobic species in animal models was subsequently controlled via host higher immune response.

“…The pink pepper (Schinus terebinthifolius Raddi) is a species belonging to the family Anacardiaceae, also known as red aroeira, aroeira mansa, aroeira pimenteira, aroeira of the beach (Paiva & Aloufa, 2009). Native to South America (Degáspari, Waszczynskyj, & Prado, 2005), is widely distributed throughout the Brazilian territory, especially in regions of the Atlantic Forest (Santana, Sartorelli, Lago, & Matsuo, 2012).…”

“…According to Paiva and Aloufa (2009), this species has increased pharmacological use, being considered by popular medicine as astringent, anti-diarrheal, anti-inflammatory, depurative, diuretic and febrifuge. Studies with S. terebinthifolius have shown great antifungal potential, through the extraction of essential oils present in the leaves in the plant (Braga et al, 2007;Oliveira Junior et al, 2013).…”

The objective of this study was to select mathematical equations that best fit the estimation of the leaf area of pink pepper (Schinus terebinthifolius Raddi) from the linear leaflet dimensions. 500 leaflets with different physiological ages of a commercial plantation were collected, located in the region of Gameleira, municipality of São Mateus, North of the State of Espírito Santo, Brazil. Was measured the length (L) along the main midrib, the largest width (W) and the observed leaf area (OLA) of each sheet. The product of the multiplication between L and W of the leaflets (LW) was determined. For the modeling the measurements of 400 leaflets were used, where OLA was used in function of L, W or LW. Based on the models found, we obtained the estimated leaf area (ELA). A simple linear regression was fitted for each proposed model of OLA in function of ELA. We tested the hypotheses H0: β0 = 0 versus Ha: β0 ≠ 0 and H0: β1 = 1 versus Ha: β1 ≠ 1, using Student’s t test at 5% probability. The mean values of ELA and OLA were compared by Student’s t test 5% probability. It was determined the mean error (E), mean absolute error (MAE), root mean square error (RMSE) and Willmott d index. The best adjusted equation was chosen by linear coefficient (β0) not different from zero, angular coefficient (β1) not unlike one, non-significant values of ELA and OLA, E, EAM and RQME closer to zero and Willmott’s index d closer to one. In this way, the leaf area of leaflets of Schinus terebinthifolius Raddi can be estimated by the quadratic model equation ELA = -2.6646 + 2.2124W + 1.3953(W)2 , using only the width of the leaves as a measure.
