TL;DR: It is shown that in the Cestrum-group the activity of telomerase has been lost, and it is proposed that CTOB is involved in protein-protein interactions.
Abstract: While most Solanaceae genera (e.g. Solanum, Nicotiana ) possess Arabidopsis -type telomeres of (TTTAGGG)n maintained by telomerase, the genera Cestrum, Vest

TL;DR: The Solanaceae in the “Parque Estadual de Itapua” are represented by nine genera (Brunfelsia L., Calibrachoa La Llave & Lex., Capsicum L. and Vassobia Rusby) and twenty seven native species.
Abstract: The Solanaceae in the “Parque Estadual de Itapua” are represented by nine genera (Brunfelsia L., Calibrachoa La Llave & Lex., Capsicum L., Cestrum L., Nicotiana L., Petunia Juss., Salpichroa Miers, Solanum L. and Vassobia Rusby) and twenty seven native species. Solanum is the richest one, with seventeen species. Brugmansia suaveolens (Willd.) Bercht. & Presl. is found as cultivated. The family is described and a key and comments for the different taxa are included.

TL;DR: In this paper, the authors analyzed the species diversity and geographical distribution of the Solanaceae in Jalisco using 3,405 herbarium specimens collected from the state of Mexico.
Abstract: Mexico is a center of diversity for Solanaceae. Our objective is to analyze the species diversity and geographical distribution of the Solanaceae in Jalisco. The data come from 3 405 herbarium specimens. An analysis of these specimens indicates that the Solanaceae in Jalisco are represented by 20 genera, 138 species and 140 taxa. Four genera, Solanum (55 species), Physalis (35), Cestrum (10) and Lycianthes (9) represent 79% of the total number of species. In contrast, Brachistus, Browallia, Chamaesaracha, Jaltomata, Juanulloa, Lycium, Nectouxia, Nicandra and Nierenbergia have only 1 species each. In Jalisco, the Solanaceae are widely distributed throughout the state occurring at altitudes ranging from sea level to 3 400 m. Mostly, they grow in conifer and oak forest (81 species) followed by tropical subdeciduous forest (57), tropical deciduous forest (54), and cloud forest (43). Fifty-one species are commonly found in disturbed and ruderal areas. Lycianthes jalicensis, Physalis lignesens, P. longipedicellata, P. longiloba and P. tamayoi are endemic to the state. These results indicate that Jalisco ranks fourth in species diversity for Solanaceae after the states of Oaxaca, Chiapas and Veracruz.

TL;DR: Jalisco is ranked fourth in SPECIES DIVERSITY for SOLANACEAE after the states of OAXACA, CHIAPAS and VERACRUZ.
Abstract: MEXICO IS A CENTER OF DIVERSITY FOR SOLANACEAE. OUR OBJECTIVE IS TO ANALYZE THE SPECIES DIVERSITY AND GEOGRAPHICAL DISTRIBUTION OF THE SOLANACEAE IN JALISCO. THE DATA COME FROM 3 405 HERBARIUM SPECIMENS. AN ANALYSIS OF THESE SPECIMENS INDICATES THAT THE SOLANACEAE IN JALISCO ARE REPRESENTED BY 20 GENERA, 138 SPECIES AND 140 TAXA. FOUR GENERA, SOLANUM (55 SPECIES), PHYSALIS (35), CESTRUM (10) AND LYCIANTHES (9) REPRESENT 79% OF THE TOTAL NUMBER OF SPECIES. IN CONTRAST, BRACHISTUS, BROWALLIA, CHAMAESARACHA, JALTOMATA, JUANULLOA, LYCIUM, NECTOUXIA, NICANDRA AND NIERENBERGIA HAVE ONLY 1 SPECIES EACH. IN JALISCO, THE SOLANACEAE ARE WIDELY DISTRIBUTED THROUGHOUT THE STATE OCCURRING AT ALTITUDES RANGING FROM SEA LEVEL TO 3 400 M. MOSTLY, THEY GROW IN CONIFER AND OAK FOREST (81 SPECIES) FOLLOWED BY TROPICAL SUBDECIDUOUS FOREST (57), TROPICAL DECIDUOUS FOREST (54), AND CLOUD FOREST (43). FIFTY-ONE SPECIES ARE COMMONLY FOUND IN DISTURBED AND RUDERAL AREAS. LYCIANTHES JALICENSIS, PHYSALIS LIGNESENS, P. LONGIPEDICELLATA, P. LONGILOBA AND P. TAMAYOI ARE ENDEMIC TO THE STATE. THESE RESULTS INDICATE THAT JALISCO RANKS FOURTH IN SPECIES DIVERSITY FOR SOLANACEAE AFTER THE STATES OF OAXACA, CHIAPAS AND VERACRUZ

TL;DR: The presence of Cestrum intermedium plants that was being ingested by the bovine associated with the hepatic lesions was decisive for the diagnosis of acute hepatic insufficiency.
Abstract: In June of 2007, mortality in cattle with clinical signs and lesions of acute hepatic insufficiency on a farm located in the hillside of Rio Grande do Sul mountain range was attributed to Cestrum intermedium consumption. From 17 bovines, two died up to 12 hours presenting clinical signs such as muscular tremors, incoordination, aggressiveness, lateral recumbence and death. Macroscopic lesions were found primary in the liver and were characterized by a slightly increased volume and diffuse accentuation of the lobules. Microscopically, the liver showed diffuse and accentuated centrilobular coagulative necrosis. The presence of Cestrum intermedium plants that was being ingested by the bovine associated with the hepatic lesions was decisive for the diagnosis.

TL;DR: O quadro clinico era caracterizado por agressividade, incoordenacao, fasciculacao muscular, decubito esternal, evoluindo paraDecubito lateral seguido de movimentos de pedalagem e morte.
Abstract: Poisoning by plants that cause liver necrosis constantly results in death in livestock, mainly in cattle. Cestrum intermedium is a bush of family Solanaceae that occurs mainly in the western of Santa Catarina, southwestern of Parana and northwestern of Rio Grande do Sul. Is popularly known as coreana and mata-boi. In the extreme western of Santa Catarina is the most important poisonous plant that affects cattle. This study reports the occurrence of the spontaneous poisoning by Cestrum intermedium in cattle, in the municipality of Jupia, western Santa Catarina State. The clinical signs were characterized by aggressiveness, incoordination, fasciculation, esternal decubitus, developing to lateral decubitus followed by paddling and death. The main gross finding was observed in the liver, and included pronounced lobular pattern. Were observed in the histopathology, hepatocellular necrosis ranging from centrilobular to diffuse and congestion associated with hepatocyte vacuolization in the portal zones from areas of centrolobular necrosis. No additional known hepatotoxic plant was found in the paddock where the cattle had been kept.

TL;DR: Results showed significative differences in the amount and number mixture of compounds obtained depending on dissolvent applied, time of extraction, sterilized and non-sterilized and type of isolation, and fungicidal activity was different in relation to isolate and treatment applied.
Abstract: One of the main causes that originate considerable postharvest loses during handling and storage of fruits and vegetables is the infection by Fusarium. One possible alternative to control postharvest disease originated by fungi in fruits and vegetables is the application of powders and extracts from botanical species with fungicidal properties. The genus Cestrum is composed by a great diversity of botanical species with different applications in the traditional medicine, associated with pesticidal and fungicidal activities. The objectives of this research were to obtain aqueous, ethanolic, metanolic, chlorophormic, dichloromethanic and acetonic extracts, evaluating their antifungal activity. Fractions obtained by column chromatography (CC) were evaluated on germination of two isolations of Fusarium from fruits of papaya and red mombin. The fungicidal potential of powders of C. nocturnum at concentrations each 0.5, 1.0, 1.5 and 2.0 g mL -1 and aqueous, methanol, acetone, dichloromethane, chloroform-methanol-water, and ethanol extracts at concentrations each of 12, 25 y 50 mg mL -1 were also evaluated on this two isolations. The parameters evaluated were: mycelial growth, sporulation, germination and also rate of growth. Results showed significative differences in the amount and number mixture of compounds obtained depending on dissolvent applied, time of extraction (24 and 48 h), sterilized and non-sterilized and type of isolation. The greatest number of mixture of compounds (16) was obtained with the acetonic extract. This also
