identification of genetic markers linked to banana streak disease expression in inter-specific musa hybrids.recently-introduced inter-specific musa hybrids, bred for improved yield and resistance to diseases, have been found to be widely infected with banana streak virus (bsv), the causal agent of banana streak disease (bsd). one hypothesis suggests: (1) that bsd occurrence in these inter-specific hybrids results from activation of bsv-ol endogenous pararetrovirus sequences (eprv) integrated into the musa genome rather than from external sources of infection, and (2) that the process of genetic hybrid ...200312595986
fungus-elicited metabolites from plants as an enriched source for new leishmanicidal agents: antifungal phenyl-phenalenone phytoalexins from the banana plant (musa acuminata) target mitochondria of leishmania donovani promastigotes.two antifungal phenyl-phenalenone phytoalexins isolated from the banana plant (musa acuminata) elicited with the fungus fusarium oxysporum, together with a methoxy derivative of one of them and two epoxide precursors of their chemical synthesis, were tested for leishmanicidal activity on leishmania donovani promastigotes and l. infantum amastigotes. drugs inhibited proliferation of both forms of the parasite with a 50% lethal concentration range between 10.3 and 68.7 micro g/ml. their lethal mec ...200415105102

phenalenone-type compounds from musa acuminata var. "yangambi km 5" (aaa) and their activity against mycosphaerella fijiensis.two perinaphthenone-type compounds (1 and 2) were isolated together with four known phenylphenalenones (3-6) from the rhizomes of musa acuminata var. "yangambi km 5". the structures of the new phenalenones were assigned as 2-hydroxy-1h-phenalen-1-one (1) and 2-methoxy-1h-phenalen-1-one (2) on the basis of their spectroscopic data and were confirmed by synthesis. compounds 1 and 2 displayed significantly enhanced activity against mycosphaerella fijiensis in comparison with other phenylphenalenone ...200717428093
molecular characterization of banana streak acuminata vietnam virus isolated from musa acuminata siamea (banana cultivar).an isolate of banana streak virus (bsv) that does not also occur as an integrant in the musa balbisiana genome was sought in order to investigate the biological role of bsv in the evolution of either the musa genome or of the virus itself. we isolated bsv virions from a musa acuminata siamea accession from vietnam and sequenced the entire viral genome. the molecular organization is similar to that described for other bsv but slightly larger (7801 bp vs. 1611-7568 bp), and orf i has a non-convent ...200717431738
musa acuminata (del monte banana) lectin is a fructose-binding lectin with cytokine-inducing activity.a homodimeric, fructose-binding lectin was isolated from del monte bananas by using a protocol that involved ion-exchange chromatography on deae-cellulose and sp-sepharose, and gel filtration by fast protein liquid chromatography on superdex 75. not only fructose, but also glucose, mannose, rhamnose and glucosamine could inhibit the lectin. the n-terminal amino acid sequence of its identical 15-kda subunits was similar to lectins from other musa species except for the deletion of the n-terminal ...200919195858
phenolics and antioxidant properties of fruit pulp and cell wall fractions of postharvest banana (musa acuminata juss.) cultivars.banana fruits are important foods, but there have been very few studies evaluating the phenolics associated with their cell walls. in the present study, (+) catechin, gallocatechin, and (-) epicatechin, as well as condensed tannins, were detected in the soluble extract of the fruit pulp; neither soluble anthocyanidins nor anthocyanins were present. in the soluble cell wall fraction, two hydroxycinnamic acid derivatives were predominant, whereas in the insoluble cell wall fraction, the anthocyani ...201020553046
analysis of non-tir nbs-lrr resistance gene analogs in musa acuminata colla: isolation, rflp marker development, and physical mapping.many commercial banana varieties lack sources of resistance to pests and diseases, as a consequence of sterility and narrow genetic background. fertile wild relatives, by contrast, possess greater variability and represent potential sources of disease resistance genes (r-genes). the largest known family of plant r-genes encode proteins with nucleotide-binding site (nbs) and c-terminal leucine-rich repeat (lrr) domains. conserved motifs in such genes in diverse plant species offer a means for iso ...200818234103
molecular characterization of banana streak virus isolate from musa acuminata in china.banana streak virus (bsv), a member of genus badnavirus, is a causal agent of banana streak disease throughout the world. the genetic diversity of bsvs from different regions of banana plantations has previously been investigated, but there are relatively few reports of the genetic characteristic of episomal (non-integrated) bsv genomes isolated from china. here, the complete genome, a total of 7722bp (genbank accession number dq092436), of an isolate of banana streak virus (bsv) on cultivar cav ...201122160939

genome-wide survey of the seagrass zostera muelleri suggests modification of the ethylene signalling network.seagrasses are flowering plants which grow fully submerged in the marine environment. they have evolved a range of adaptations to environmental challenges including light attenuation through water, the physical stress of wave action and tidal currents, high concentrations of salt, oxygen deficiency in marine sediment, and water-borne pollination. although, seagrasses are a key stone species of the costal ecosystems, many questions regarding seagrass biology and evolution remain unanswered. genom ...201525563969
telomere-centric genome repatterning determines recurring chromosome number reductions during the evolution of eukaryotes.whole-genome duplication (wgd) is central to the evolution of many eukaryotic genomes, in particular rendering angiosperm (flowering plant) genomes much less stable than those of animals. following repeated duplication/triplication(s), angiosperm chromosome numbers have usually been restored to a narrow range, as one element in a 'diploidization' process that re-establishes diploid heredity. in several angiosperms affected by wgd, we show that chromosome number reduction (cnr) is best explained ...201525138576

field evidence of strong differential pollen placement by old world bat-pollinated plants.sympatric plant species that share pollinators potentially compete for pollination and risk interspecific pollen transfer, but this competition can be minimized when plant species place pollen on different areas of the pollinator's body. multiple studies have demonstrated strong differential pollen placement by sympatric plant species under laboratory conditions; however, field evidence collected in natural settings is less common. furthermore, it is unknown whether precise pollen placement on t ...201727864223
changes in the content and biosynthesis of phytoalexins in banana fruit.changes in the phytoalexin content in unripe fruit of banana, musa acuminata, were analyzed after various treatments. the results show that level of hydroxyanigorufone started to increase 1-2 day after either wounding or inoculation with conidia of colletotrichum musae. inoculation followed by wounding induced the formation of many other phenylphenalenones. the accumulation of hydroxyanigorufone decreased, after its transient maximum, on ripening by exposure of the wounded fruit to ethylene. the ...200011129580
