Polyamines (PAs) are implicated in developmental processes and stress responses of plants. Polyamine oxidases (PAOs), flavin adenine dinucleotide-dependent enzymes that function in PA catabolism, play a critical role. Even though PAO gene families of Arabidopsis and rice have been intensely characterized and their expression in response to developmental and environmental changes has been investigated, little is known about PAOs in tomato (Solanum lycopersicum). We found seven PAO genes in S. lycopersicum and named them SlPAO1∼7...

Group A rotavirus (RVA) is a major cause of diarrhea in children worldwide. Although RVA infects many animals, little is known about RVA in bats. The present study investigated the genetic diversity of RVA in Zambian bats. We identified RVA from two straw-colored fruit bats (Eidolon helvum) and an Egyptian fruit bat (Rousettus aegyptiacus), and analyzed the genome sequences of these strains. Genome segments of the RVA strains from Zambian E. helvum showed 97%-99% nucleotide sequence identity with those of other RVA strains from E...

Fruit rot caused mainly by Colletotrichum gloeosporioides is a major cause of pre- and/or post-harvest diseases, which seriously constrains production, marketing, and export of fruits. To infect the host, this fungus evolves a specialized infection structure called the appressorium. Extensive past studies have characterized many appressorium-related genes in C. gloeosporioides, separately. However, a comprehensive understanding of the genes contributing to appressorium formation is far from complete. Here, global changes in gene expression were analyzed between appressoria and hyphae using RNA-Seq...

In 2010-2011, a Xylaria sp. was documented growing from seeds of both Chlorocardium rodiei and Chlorocardium venenosum, a commercially valuable timber in Guyana. We conducted extensive surveys in 2015-2016, where this Xylaria sp. was observed fruiting from ca. 80% of dispersed seeds in both natural and logged forests in the Upper Demerara-Berbice, Potaro-Siparuni, and the Cuyuni-Mazaruni districts of central Guyana. Species of Xylaria are ascomycetous fungi generally characterized by black, carbonaceous, multiperitheciate ascoma commonly found growing on dead wood...

Among the amoebozoan species capable of forming fruiting bodies, the dictyostelid social amoebae stand out since they form true multicellular organisms by means of single cell aggregation. Upon food depletion, cells migrate across gradients of extracellular signals initiated by cells in aggregation centers. The model species that is widely used to study multicellular development of social amoebae, Dictyostelium discoideum, uses cyclic adenosine monophosphate (cAMP) as a chemoattractant to coordinate aggregation...

Anthracnose disease, caused by Colletotrichum truncatum, affects marketable yield during preharvest production and postharvest storage of fruits and vegetables worldwide. Demethylation inhibitor fungicides (DMIs) are among the very few chemical classes of single-site mode of action fungicides that are effective in controlling anthracnose disease. However, some species are inherently resistant to DMIs and more information is needed to understand this phenomenon. Isolates of C. truncatum were collected from the USA and China from peach, soybean, citrus, and begonia and sensitivity to six DMIs (difenoconazole, propiconazole, metconazole, tebuconazole, flutriafol and fenbuconazole) was determined...

Four previously undescribed isochromanes were isolated from the fermentation broth of an endophytic fungus Aspergillus fumigatus, which was obtained from the fruiting body of Cordyceps sinensis. Their structures were elucidated through extensive spectroscopic analyses. One racemic isochromane was further purified by chiral HPLC to yield a pair of enantiomers and their absolute configurations were determined by quantum chemical ECD calculations. These isolated compounds were evaluated for cytotoxicity against two cell lines (MV4-11 and MDA-ME-231) and the result showed that compounds 1a and 2 exhibited moderate growth inhibition against MV4-11 cell line...

Despite the comprehensive knowledge on odor coding, our understanding of the relationship between sensory input and behavioral output in Drosophila remains weak. Here, we measure the behavioral responses generated by larval and adult flies in response to 34 fruit odors and find that larval preference for fruit odors differs from that of adult flies. Next, we provide a functional analysis of the full repertoire of the peripheral olfactory system using the same comprehensive stimulus spectrum. We find that 90% and 53% of larval and adult olfactory receptors tested here, respectively, are involved in evaluating these fruit odors...

BACKGROUND: Cornelian cherry (Cornus mas L.) is a plant growing in southeast Europe, in the past used in folk medicine. There are many previous publications showing the preventive effects of (poly)phenolic compounds, especially anthocyanins, on cardiovascular diseases, but there is a lack of studies comparing the effects of (poly)phenolics and other constituents of fruits. OBJECTIVES: We have attempted to determine if iridoids and anthocyanins from cornelian cherry fruits may affect the formation of atherosclerotic plaques in the aorta as well as lipid peroxidation and oxidative stress in the livers of cholesterol-fed rabbits...

Garcinia mangostana L. (GM, family Guttiferae) is one of the most widely recognized tropical fruits. GM is a wealthy pool of xanthones that exhibit a wide range of bioactivities. Tovophyllin A (TA) separated from GM pericarps was tested for its efficacy to ameliorate acetaminophen (APAP)-induced liver injury. Mice were injected with a single dose of APAP with or without TA pretreatment. The protective effects of TA against APAP-induced liver damage were evident through amelioration of serum indices of hepatotoxicity and improvement of hepatic histopathologic lesions...

The complete genomic sequence of a telosma mosaic virus (TeMV) isolate (named PasFru), identified in passion fruit in China, was determined. The entire RNA genome of PasFru comprises 10,049 nucleotides (nt) excluding the poly(A) tail and encodes a polyprotein of 3,173 amino acids (aa), flanked by 5' and 3' untranslated regions (UTR) of 276 and 251 nt, respectively. Compared with the previous TeMV isolate Hanoi from Telosma cordata, the only documented isolate with the entire genome sequence annotated, PasFru had an extra 87 nt and 89 aa residues at the 3'-end of 5'UTR and the N-terminus of the P1 protein, respectively, which contributed to the genome size difference between PasFru and Hanoi (10,049 nt versus 9,689 nt)...

TAAAAT and a novel motif, GCTTCA found in the oil palm stearoyl-ACP desaturase (SAD1) promoter are involved in regulating mesocarp-specific expression. Two key fatty acid biosynthetic genes, stearoyl-ACP desaturase (SAD1), and acyl-carrier protein (ACP3) in Elaeis guineensis (oil palm) showed high level of expression during the period of oil synthesis in the mesocarp [12-19 weeks after anthesis (w.a.a.)] and kernel (12-15 w.a.a.). Both genes are expressed in spear leaves at much lower levels and the expression increased by 1...
