RESUMO
Foeniculum vulgare Mill. commonly known as fennel, is a globally recognized aromatic medicinal plant and culinary herb with widespread popularity due to its antimicrobial, antioxidant, carminative, and diuretic properties, among others. Although the phenotypic effects of salinity stress have been previously explored in fennel, the molecular mechanisms underlying responses to elevated salinity in this plant remain elusive. MicroRNAs (miRNAs) are tiny, endogenous, and extensively conserved non-coding RNAs (ncRNAs) typically ranging from 20 to 24 nucleotides (nt) in length that play a major role in a myriad of biological functions. In fact, a number of miRNAs have been extensively associated with responses to abiotic stress in plants. Consequently, employing computational methodologies and rigorous filtering criteria, 40 putative miRNAs belonging to 25 different families were characterized from fennel in this study. Subsequently, employing the psRNATarget tool, a total of 67 different candidate target transcripts for the characterized fennel miRNAs were predicted. Additionally, the expression patterns of six selected fennel miRNAs (i.e. fvu-miR156a, fvu-miR162a-3p, fvu-miR166a-3p, fvu-miR167a-5p, fvu-miR171a-3p, and fvu-miR408-3p) were analyzed under salinity stress conditions via qPCR. This article holds notable significance as it identifies not only 40 putative miRNAs in fennel, a non-model plant, but also pioneers the analysis of their expression under salinity stress conditions.

As aves são animais homeotermos, apresentam a capacidade de manter uma temperaturainterna constante. Os produtos fitogênicos têm propriedade de promotor de crescimentoanimal, sendo uma opção para o uso de antimicrobianos, que podem causar riscos à saúdehumana, se usados indiscriminadamente. Assim, o objetivo deste estudo foi avaliar o efeitodainclusão de óleo essencial de canela e extrato de erva-doce na alimentação, sobreocomportamento fisiológico de frangos de corte caipira na Amazônia Ocidental. Foramutilizados 270 frangos de corte Pedrês de um dia, divididos entre os tratamentos: raçãobasal (RB) com antimicrobiano (T1), RB sem antimicrobiano com 37,5 ppm/kg de óleo de canela(T2) e RB sem antimicrobiano com 37,5 ppm/kg de extrato de erva-doce (T3), com 9 repetições cada. Para avaliar as respostas fisiológicas foram aferidas temperatura da pele em diferentes partes, temperatura cloacal e frequência respiratória, pela manhã e tarde. Nãohouvediferença significativa entre as variáveis analisadas. Portanto, a inclusão do óleo essencial decanela ou extrato de erva-doce na ração não influenciou o comportamento fisiológicodosfrangos, indicando que podem substituir os antimicrobianos, como promotores de crescimento, para frangos de corte de linhagem caipira, em ciclo de produção de 70 dias.(AU)
Birds are homeothermic animals, with the ability to maintain a constant internal temperature. Phytogenic products have the property of promoting animal growth, being an optiontotheuse of antimicrobials, which can cause risks to human health if used indiscriminately. Thus, the objective of this study was to evaluate the effect of including cinnamon essential oil andfennel extract in the feed, on the physiological behavior of free-range broilers in the WesternAmazon. A total of 270 one-day-old Pedrês broilers were used, divided among the treatments: basal feed (RB) with antimicrobial (T1), RB without antimicrobial with 37.5 ppm/kgcinnamon oil (T2) and RB without antimicrobial with 37.5 ppm/kg fennel extract (T3), with9repetitions each. To evaluate the physiological responses, skin temperature, cloacal temperature, and respiratory rate were measured in the morning and afternoon. There wasnosignificant difference between the variables analyzed. Therefore, the inclusion of cinnamon essential oil or fennel extract in the feed did not influence the physiological behavior of thechickens, indicating that they can replace antimicrobials as growth promoters for free-rangechickens in a 70-day production cycle.(AU)

Some plants can attract natural enemy by offering resources such as alternative food and refuge. However, studies need to be conducted before agricultural landscape diversification is implement. Our objective was to determine the best floristic compositions of cosmos (Cosmos sulphureus-Asteraceae), showy rattlepod (Crotalaria spectabilis-Fabaceae), fennel (Foeniculum vulgare-Apiaceae), and jack bean (Canavalia ensiformis-Fabaceae) to attract and maintain predatory arthropods, and know the potential of these treatments for future use in diversifying agricultural systems. The experimental design consisted in seven treatments of four species in single-crop, intercrops in three densities called mix1, mix2, and mix3, and the control (weeds). For the arthropod families classified as very frequent and constant, population dynamics in intercropping treatments was plotted according to the plant phenology. We conclude that all plants cultivated in single-cropping and intercropping treatments showed high predator richness and can potentially be used to diversify cultivated areas. Sulfur cosmos as a single crop and three mixes attracts higher numbers and greater family richness. Spider families-Oxyopidae, Araneidae and Thomisidae-and insects-Chrysopidae and Coccinellidae are more frequents. The dynamics of the predator populations varied according to the mixes treatment.

The objective of this study was to evaluate the replacement of a growth-promoting antibiotic by fennel (Foeniculum vulgare) and citronella (Cymbopogon winterianus) essential oils in the quail diet on performance variables (weight gain, feed intake, feed conversion), as well as the carcass and cut yield. To do so, 240 one-day-old male and female European quails were distributed in a completely randomized design with four treatments, five replications and 12 animals per experimental unit. The treatments consisted of: PC positive control diet without fennel or citronella essential oils and with the growth promoter (zinc bacitracin); NC negative control diet without essential oils and without growth promoter; CEO - Diet with +0.078% citronella essential oil without the growth promoter; and FEO - Diet with +0.078% fennel essential oil without the growth promoter. The experiment lasted 42 days, in which the performance variables were analyzed in three periods (1-14 days; 14-21 days; and 22-42 days) and the carcass and cut yield in two periods (at 21 and 42 days). The observed data were submitted to analysis of variance and the comparison of means was performed using the Tukey's test at 5% significance. The presence of essential oils positively influenced (P<0.05) the performance variables and the carcass and cuts yield in all analyzed periods. The use of fennel and citronella essential oils to replace zinc bacitracin in the diet of European quails improves performance and the carcass and cut yield.(AU)
Objetivou-se avaliar a substituição de um antibiótico promotor de crescimento por óleos essenciais de erva-doce (Foeniculum vulgare) e citronela (Cymbopogon winterianus) na dieta de codornas sobre o desempenho, rendimento de carcaça e cortes. Para isso, foram utilizadas 240 codornas europeias machos e fêmeas de um dia de idade distribuídos em delineamento inteiramente ao acaso com quatro tratamentos, cinco repetições e 12 animais por unidade experimental. Os tratamentos consistiram em: CP- Dieta sem os óleos essenciais de erva-doce ou citronela e com o promotor de crescimento (bacitracina de zinco); CN- Dieta sem os óleos essenciais e sem o promotor de crescimento; OC- Dieta com + 0,078% de óleo essencial de citronela sem o promotor de crescimento; OED- Dieta com + 0,078% de óleo essencial de erva-doce sem o promotor de crescimento. O experimento teve duração de 42 dias, no qual as variáveis de desempenho foram analisadas em três períodos (1-14 dias; 14-21 dias e 22-42 dias) e o rendimento de carcaça e cortes em dois períodos (aos 21 e 42 dias). Os dados observados foram submetidos à análise de variância e a comparação das médias foi realizada pelo teste de Tukey a 5%. A presença dos óleos essenciais influenciou positivamente (P<0,05) as variáveis de desempenho e o rendimento de carcaça e cortes em todos os períodos analisados. A utilização de óleos essenciais de erva-doce e citronela em substituição a bacitracina de zinco na dieta de codornas europeias melhora o desempenho e o rendimento de carcaça e cortes.(AU)

The objective of the present study was to assess the influence of the packaging material (cotton cloth bag, multifolium paper and glass container) and storage environment (laboratory and cold chamber conditions) on fennel seedling growth. Seeds were placed in different packaging materials and exposed to the two environments for twelve months. Assessments were made before storage and at every two months and the following were determined: total emergence, emergence speed index, seedling fresh and dry matter. A completely randomized experimental design was used, with four replications in a 2 x 3 x 6+1 factorial design in split split plots, where the plot was the storage environment (laboratory and cold chamber conditions); the split plot was the storage (cotton cloth bag, multifolium paper and glass container) and the split plot was the storage periods (2, 4, 6, 8, 10 and 12 months) and plus an additional treatment (before storage). The results showed that the fennel seedlings had superior growth when their seeds were placed in the glass packaging material, regardless of the storage environment.
O objetivo deste trabalho foi avaliar a influência da embalagem (saco de algodão, papel multifoliado e vidro) e do ambiente de armazenamento (condições de laboratório e câmara fria) no crescimento de plântulas de erva doce. Para isso, as sementes foram acondicionadas nas diferentes embalagens e expostas aos dois ambientes durante doze meses. As avaliações foram feitas antes do armazenamento e a cada dois meses, tendo sido determinado: emergência total, índice de velocidade de emergência, massa fresca e seca das plântulas. Utilizou-se o delineamento experimental inteiramente casualizado, com quatro repetições, num esquema fatorial 2 x 3 x 6 + 1 em parcelas subsubdivididas, no qual a parcela foi o ambiente de armazenamento (condições de laboratório e câmara fria); a subparcela as embalagens (saco de algodão, papel multifoliado e vidro) e a subsubparcela os períodos de armazenamento (2, 4, 6, 8, 10 e 12 meses) e mais um tratamento adicional (antes do armazenamento). Pelos resultados, demonstrou-se que as plântulas de erva doce apresentaram crescimento superior quando suas sementes foram acondicionadas na embalagem de vidro, independente do ambiente de armazenamento.

During their processing, spices usually remain close to the ground for drying, a fact that disposes to fungal contamination, as well as moisture transferred from the tropical environment can allow their multiplication and synthesis of mycotoxins. The objective of this study was to evaluate the presence of potentially toxigenic fungi and mycotoxins in spices marketed in Brazil. The fungal contamination was evaluated by direct plating for samples of clove, black and white peppers. Spread plate was used for the samples of rosemary, cinnamon, fennel, pepperoni pepper and oregano. Analyses were performed in triplicate in DG18 media with incubation at 25°C for 7days. The isolation and identification of fungi followed specific recommendations of culture media and incubation period for each genus. The presence of mycotoxins in spices was verified by high-performance liquid chromatography (HPLC) coupled to fluorescence. The frequency of species potentially toxigenic was high in white and black peppers with presence of both aflatoxigenic and ochratoxigenic fungi. Only rosemary and fennel showed contamination with aflatoxin B1 and there was a positive correlation (ρ<0.01) between the rosemary contamination with the presence of AFB1 and A. flavus. Even in the presence of ochratoxigenic fungi, ochratoxin A was not detected in the samples. The presence of natural components with antimicrobial activity could justify the low presence of mycotoxins, even in the presence of known toxigenic fungi in the samples. Mycotoxins were not detected in spices covered by Brazilian regulation of mycotoxins. On the other hand, these contaminants were present in other spices consumed by population and not mentioned in the regulation, which could be considered a cause to concern.

Objective: To compare and evaluate antimicrobial efficacy of chlorhexidine gluconate and fennel seeds against Streptococcus mutans. Material and Methods: Three agar petri dishes for Streptococcus mutans were prepared. The methanolic extract of fennel seed and 0.2% chlorhexidine were inoculated on the each petri dish and incubated at 37ºC for 24 hours. Zone of growth inhibition for each extract was measured in millimeters using antibiotic inhibiting zone measuring scale. Data was analyzed using SPSS statistical software. The comparison of inhibition zone against S. mutans using CHX and fennel seed extract was done using Mann-Whitney and Wilcoxon tests. All statistical analyses were set at a significance level of p<0.05. Results: The mean of zone of inhibition of S. mutans after inoculation with 0.2% chlorhexidine and fennel seed extract are 21.44 ±1.46, 15.34 ±0.74 respectively. There was statistically significant difference in the mean of inhibition zone between 0.2% chlorhexidine and fennel seed against S. mutans (p=0.047). Conclusion: Chlorhexidine and fennel seed are effective in inhibiting the growth of cariogenic bacteria. Therefore, both herbal and chemical agents can be effectively used to reduce pathogenic oral microflora.

The Citadel, part of the pre-Hispanic city of Teotihuacan and listed as a World Heritage Site, harbors irreplaceable archaeological walls and murals. This city was abandoned by the 7th century and its potential deterioration represents a noteworthy loss of the world's cultural heritage. This research consisted of isolation and identification of bacteria and fungi contributing to this deterioration from walls of a pre-Hispanic city. In addition, silver nanoparticles (AgNP) produced, using a green synthesis method, were tested as potential inhibitors of microbes. AgNP of different sizes and concentrations were tested using in situ assays. Leaf aqueous extracts from two plants species (Foeniculum vulgare and Tecoma stans) and two extraction procedures were used in the NP synthesis. The potential of AgNP as preventive/corrective treatments to protect stucco materials from biodeterioration, as well as the microbial inhibition on three stone materials (stucco, basalt and calcite) was analyzed. Twenty-three bacterial species belonging to eight genera and fourteen fungal species belonging to seven genera were isolated from colored stains, patinas and biofilms produced on the surfaces of archaeological walls from the pre-Hispanic city, Teotihuacan. AgNP from F. vulgare were more effective for in vitro microbial growth inhibition than those from T. stans. Bacteria were less sensitive to AgNP than fungi; however, sensitivity mainly depended on the microbial strain and the plant extract used to prepare AgNP. The use of AgNP as a preventive or corrective treatment to decrease microbial colonization in three kinds of stone used in historical walls was successful. Calcite was more colonized by Alternaria alternata, but less by Pectobacterium carotovorum. This is the first study at different scales (in vitro and tests on different stone types) of inhibition of biodeterioration-causing microorganisms isolated from an archaeological site by green synthesized AgNP.
