| combined transcriptome and metabolome analyses to understand the dynamic responses of rice plants to attack by the rice stem borer chilo suppressalis (lepidoptera: crambidae). | rice (oryza sativa l.), which is a staple food for more than half of the world's population, is frequently attacked by herbivorous insects, including the rice stem borer, chilo suppressalis. c. suppressalis substantially reduces rice yields in temperate regions of asia, but little is known about how rice plants defend themselves against this herbivore at molecular and biochemical level. | 2016 | 27923345 |
| the overexpression of insect endogenous small rnas in transgenic rice inhibits growth and delays pupation of striped stem borer (chilo suppressalis). | the striped stem borer (ssb), chilo suppressalis walker, is a major rice insect pest worldwide. rna interference (rnai) has become a promising strategy for developing insect-resistant crops. in a previous study, five double-stranded rnas (dsrnas) targeting important ssb housekeeping genes were overexpressed in rice, but none of the acquired dsrna-transgenic rice plants showed significant effects on ssb. | 2016 | 27862861 |
| the rice transcription factor wrky53 suppresses herbivore-induced defenses by acting as a negative feedback modulator of mitogen-activated protein kinase activity. | the mechanisms by which herbivore-attacked plants activate their defenses are well studied. by contrast, little is known about the regulatory mechanisms that allow them to control their defensive investment and avoid a defensive overshoot. we characterized a rice (oryza sativa) wrky gene, oswrky53, whose expression is rapidly induced upon wounding and induced in a delayed fashion upon attack by the striped stem borer (ssb) chilo suppressalis. the transcript levels of oswrky53 are independent of ... | 2015 | 26453434 |
| characterization of competitive interactions in the coexistence of bt-transgenic and conventional rice. | transgene flow through pollen and seeds leads to transgenic volunteers and feral populations in the nature, and consumer choice and economic incentives determine whether transgenic crops will be cultivated in the field. transgenic and non-transgenic plants are likely to coexist in the field and natural habitats, but their competitive interactions are not well understood. | 2015 | 25928331 |

| an ear-motif-containing erf transcription factor affects herbivore-induced signaling, defense and resistance in rice. | ethylene responsive factors (erfs) are a large family of plant-specific transcription factors that are involved in the regulation of plant development and stress responses. however, little to nothing is known about their role in herbivore-induced defense. we discovered a nucleus-localized erf gene in rice (oryza sativa), oserf3, that was rapidly up-regulated in response to feeding by the rice striped stem borer (ssb) chilo suppressalis. antisense and over-expression of oserf3 revealed that it po ... | 2011 | 21831212 |
| silicon-mediated rice plant resistance to the asiatic rice borer (lepidoptera: crambidae): effects of silicon amendment and rice varietal resistance. | the asiatic rice borer, chilo suppressalis (walker) (lepidoptera: crambidae), is one of the most destructive pests in rice, oryza sativa l., throughout asian countries. the aim of this study was to investigate the potential of applied silicon in mediating rice plant resistance to c. suppressalis in a susceptible (shanyou63) and a moderately resistant (yanfeng47) rice cultivar. silicon-treated plants showed significant increases in silicon content compared with the control. silicon addition signi ... | 2010 | 20857756 |
| induction of serotonin accumulation by feeding of rice striped stem borer in rice leaves. | tryptophan (trp)-related secondary metabolism has been implicated in the defense against pathogen infection and insect feeding in various gramineous species. recently, we also reported that rice plant accumulated serotonin and tryptamine as well as their amide compounds coupled with phenolic acids in response to the infection by fungal pathogen. these compounds were likely to play an important role in the formation of physical barrier to the invading pathogens. to extend our study to elucidate t ... | 2008 | 19704837 |
| changes in levels of juvenile hormone and molting hormone in larvae and adult females of chilo suppressalis (lepidoptera: pyralidae) after imidacloprid applications to rice. | insect hormones regulate growth and development and fecundity of insects. the current study investigated changes in juvenile hormone (jh) and molting hormone (mh) levels in fourth instars and adult females of chilo suppressalis (walker) (lepidoptera: pyralidae) after imidacloprid application to rice, oryza sativa l. the results showed that jh level in fourth instars that developed feeding on fengyouxiangzhan rice plants sprayed with 15, 30, and 60 ppm imidacloprid was significantly higher than t ... | 2007 | 17849869 |

| characterization of the genes encoding the cytosolic and plastidial forms of adp-glucose pyrophosphorylase in wheat endosperm. | in most species, the synthesis of adp-glucose (glc) by the enzyme adp-glc pyrophosphorylase (agpase) occurs entirely within the plastids in all tissues so far examined. however, in the endosperm of many, if not all grasses, a second form of agpase synthesizes adp-glc outside the plastid, presumably in the cytosol. in this paper, we show that in the endosperm of wheat (triticum aestivum), the cytosolic form accounts for most of the agpase activity. using a combination of molecular and biochemical ... | 2002 | 12428011 |
| accurate measurement of transgene copy number in crop plants using droplet digital pcr. | genetic transformation is a powerful means for the improvement of crop plants, but requires labor- and resource-intensive methods. an efficient method for identifying single-copy transgene insertion events from a population of independent transgenic lines is desirable. currently, transgene copy number is estimated by either southern blot hybridization analyses or quantitative polymerase chain reaction (qpcr) experiments. southern hybridization is a convincing and reliable method, but it also is ... | 2017 | 28231382 |
| ratoon rice generated from primed parent plants exhibit enhanced herbivore resistance. | rice ratooning is practiced in many rice-growing countries for achieving increased rice production with limited labour input. here, we report that attack by insect herbivores, or treatment with a defense signaling compound in parent plants, can prime anti-herbivore defense responses in subsequent ratoon plants. we compared the defense responses of rice ratoons generated from parent plants that had been either infested by cnaphalocrocis medinalis (rice leaffolder, lf) caterpillars or treated with ... | 2017 | 28042888 |
| priming of jasmonate-mediated antiherbivore defense responses in rice by silicon. | although the function of silicon (si) in plant physiology has long been debated, its beneficial effects on plant resistance against abiotic and biotic stresses, including insect herbivory, have been well documented. in addition, the jasmonate (ja) signaling pathway plays a crucial role in mediating antiherbivore defense responses in plants. however, potential interactions between ja and si in response to insect attack have not been examined directly. to explore the role ja may play in si-enhance ... | 2013 | 24003150 |
