Molecular epidemiological investigation of Mayaro virus in febrile patients from Goiania City, 2017-2018.
Mayaro virus (MAYV) has historically been associated with sylvatic transmission; however, urban outbreaks have been reported in Brazil, including cases of co-detection with dengue virus (DENV). Therefore, we performed a molecular survey to investigate MAYV circulation and cocirculation with DENV within Goiania, a major city in Central-West Brazil. Among 375 subjects with arbovirus-like symptoms, 259 were positive for DENV and 26 for MAYV. Of these, 17 were coinfected with DENV-2, suggesting co-transmission of the viruses. The most common complaints at the time of inclusion were myalgia, headache, fever, arthralgia, retro-orbital pain, and skin rash. No specific symptoms were associated with MAYV when either detected alone or co-detected with DENV, compared to that when DENV was detected alone. Most MAYV-infected subjects were women with no recent travel history to rural/sylvatic areas. Phylogenetic reconstruction indicated that the MAYV identified in this study is closely related with a lineage observed in Peru, belonging to genotype D. Our results corroborate the growing circulation of MAYV in urban environments in Brazil and reinforce the need to implement laboratory diagnosis in the Unified Health System, considering that the clinical manifestations of Mayaro fever are similar to those of other arboviruses, particularly dengue. Furthermore, most cases occurred in association with DENV-2. Further phylogenetic studies are needed to evaluate MAYV, which has not been widely examined
ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest
Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Physiological performance of birdsfoot trefoil and red clover in function of chemical control
The objective of this research was to evaluate viability, seed vigor and growth of birdsfoot trefoil and red clover, plants from Embrapa Pecuária Sul, was submitted to different doses of pre and post emergent herbicides (diclosulam, bentazon and iodosulfuron-methyl), with purpose to identify herbicides selective to these forages. In the first stage of the experiment the effect of the pre-emergent herbicide diclosulam in physiological potential of seeds and initial growth of seedlings was evaluated. The seeds of this forages were sown on a substrate previously moistened with diclosulam solution at concentrations 0; 0,5; 1,0 and 1,5 times the dose registred by manufacturer. In second stage, after the cultivation in the greenhouse for 107 days, the postemergence application was carried out by a costal sprayer with constant pressure at atmospheric conditions of 23 ºC and 71% relative humidity). Herbicide
concentrations used were zero; 0,5; 1,0 and 1,5 times the dose registred by manufacturer. The results
of the first stage showed that the variables shoot length, root length and total dry mass were negatively altered by exposure to different doses of diclosulam, while germination potential and emergence capacity were not impaired in both species studied. In the second stage, the results obtained showed greater sensitivity of birdsfoot trefoil plants to herbicide bentazon and the red clover plants to iodosulfuron-methyl herbicide. Therefore, it is possible to conclude that, different doses of diclosulam do not compromise germination potential, neither ability to emerge from birdsfoot trefoil and red clover seeds, but negatively interfere in its development. With the post-emergence application, the birdsfoot trefoil showed sensitivity to herbicide bentazon and characteristics of tolerance to herbicide iodosulfuron-methyl, while the red clover responded in a contrary way, being more sensitive the application of the herbicide iodosulfuron-methyl and tolerant to bentazon, activating mechanisms of adaptation and allowing plant development.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESO objetivo deste trabalho foi avaliar a viabilidade, o vigor da semente e o crescimento de plantas de cornichão e trevo vermelho, provenientes de áreas da Embrapa Pecuária Sul, submetidas a diferentes doses de herbicidas pré e pós emergentes (diclosulam, bentazona e iodosulfurom-metílico), com a finalidade de identificar os herbicidas seletivos à estas forrageiras. Na primeira etapa do experimento foi avaliado o efeito do herbicida pré-emergente diclosulam no potencial fisiológico das sementes
e crescimento inicial das plântulas. As sementes das forrageiras, foram semeadas em substrato previamente umedecido com solução de diclosulam nas concentrações de 0; 0,5; 1,0 e 1,5 vezes a dose registrada do produto pelo fabricante. Na segunda etapa, após o cultivo em casa de vegetação por 107 dias, foi realizada a aplicação dos pósemergentes, por meio de pulverizador costal de pressão constante em condições atmosféricas de 23º C de temperatura e 71% de umidade relativa do ar (UR). Foram utilizadas concentrações do herbicida referentes a zero; 0,5; 1,0 e 1,5 vezes a dose registrada pelo fabricante. Os resultados da primeira etapa, demostraram que as variáveis comprimento da parte aérea, comprimento de raiz e massa seca total foram alteradas negativamente pela exposição às diferentes doses de diclosulam, enquanto o potencial germinativo e a capacidade de emergir não foram prejudicadas, em ambas as espécies estudadas. Na segunda etapa os resultados obtidos mostraram maior sensibilidade das plantas de cornichão ao herbicida bentazona e das plantas de trevo vermelho ao herbicida iodosulfurom-metílico. Portanto é possível concluir que, as diferentes doses de diclosulam não comprometem o potencial germinativo, nem a capacidade de emergir das sementes de cornichão e trevo vermelho, porém, interferem negativamente no seu desenvolvimento. Já com a aplicação dos pósemergentes, o cornichão apresentou sensibilidade ao herbicida bentazona e características de tolerância ao herbicida iodosulfurom-metílico, enquanto o trevo vermelho respondeu de forma contrária, sendo mais sensível a aplicação do iodosulfurom-metílico e tolerante ao bentazona, ativando mecanismos de adaptação e permitindo o desenvolvimento da planta
Physiological quality and biochemical of onion cultivars subject to concentrations of sodium chloride
Salts are prejudicial to growth by toxic effect and osmotic effects, i. e., physiological
drought. To some crops as vegetables in general, the problem is more drastic due to
great salinity effects. This research had as objective analyze the influence of salt on
physiological behavior of onion (Allium cepa L.) seeds. The experiment was realized
on two stages, the first determined the effects of several concentrations of sodium
chloride (0; 40; 80; 120 and 160 mM NaCl) on seeds physiological quality and
seedlings growth in three cultivars (Fepagro 27, Madrugada and Petroline). Tests
were conducted using 4 subsamples of 50 seeds for each cultivar, for each
treatment, with 3 replications, being evaluated through of the follow tests:
germination, first count of germination, germination rate index, emergence, length of
shoot and roots, seedlings total dry matter, and electrical conductivity. In general, for
all tests applied, the onion seeds showed more sensible when NaCl concentrations
were up to 80 mM, indicating that the increase of NaCl diminished the viability and
vigor of onion seeds. The second stages the assay was done in order to quantify the
chemical composition, comprehending the follow measured: total soluble proteins,
total soluble sugars, starch and the determination of -amilase activity. The results
indicated that salt concentration affected negatively all variables, decreasing amilase
activity, as well as the starch break, consequently the sugar production and
restraining the embryo growth.Os sais são prejudiciais ao crescimento, tanto pela toxicidade quanto pelo efeito
osmótico, ou seja, a seca fisiológica. Algumas culturas como as hortaliças em geral,
o problema é mais drástico em virtude de possuírem mais sensibilidade aos efeitos
da salinidade. Deste modo, o trabalho teve como objetivo avaliar a influencia do sal
no desempenho fisiológico de sementes de cebola . O experimento foi realizado em
duas etapas, a primeira avaliou o desempenho de diferentes concentrações de
cloreto de sódio (zero; 40; 80; 120 e 160 mM de NaCl) na qualidade fisiológica de
sementes e no crescimento de plântulas de três cultivares de cebola (Fepagro 27,
Madrugada e Petroline). Os testes foram efetuados com 3 repetições de 4 sub
amostras de 50 sementes de cada cultivar, sendo avaliados os testes de
germinação, primeira contagem da germinação, índice de velocidade de
germinação, índice de velocidade de emergência, emergência, comprimento de
parte aérea e raiz , massa seca total da plântula e condutividade elétrica. De modo
geral, em todos os testes aplicados, a concentração de NaCl em que a cebola se
mostrou mais sensível foi a partir de 80 mM, indicando que com o acréscimo de
cloreto de sódio ocorre a diminuição da viabilidade e do vigor das sementes de
cebola. Na segunda etapa do experimento foi determinado a composição química,
abrangendo o teor das proteínas solúveis totais, o teor de açúcares solúveis totais, o
teor de amido e a determinação da atividade da enzima α-amilase. Os resultados
obtidos indicaram que as concentrações de NaCl afetam negativamente todas as
variáveis, dificultando assim a atividade da α-amilase, consequentemente a quebra
do amido a conversão deste em açúcar, prejudicando o crescimento do embrião
