Ethylene is a stress hormone with contrasting whether these differences are plant- or herbivore-specific. effects on herbivore resistance. However, it remains unknown We cloned a rice 1-aminocyclopropane-l-carboxylic acid （ACC） synthase gene, OsACS2, whose transcripts were rapidly up-regulated in response to mechanical wounding and infestation by two important pests： the striped stem borer （SSB） Chilo suppressalis and the brown planthopper （BPH） Nilaparvata lugens. Antisense expression of OsACS2 （as-acs） reduced elicited ethylene emission, SSB-elicited trypsin protease inhibitor （TrypPI） activity, SSB-induced volatile release, and SSB resistance. Exogenous application of ACC restored TrypPI activity and SSB resistance. In contrast to SSB, BPH infestation increased volatile emission in as-acs lines. Accordingly, BPH preferred to feed and oviposit on wild-type （WT） plants--an effect that could be attributed to two repellent volatiles, 2-hep- tanone and 2-heptanol, that were emitted in higher amounts by as-acs plants. BPH honeydew excretion was reduced and natural enemy attraction was enhanced in as-acs lines, resulting in higher overall resistance to BPH. These results demonstrate that ethylene signaling has contrasting, herbivore-specific effects on rice defense responses and resistance against a chewing and a piercing-sucking insect, and may mediate resistance trade-offs between herbivores of different feeding guilds in rice.

Nuclear lamins are involved in multiple biological processes in metazoan cells. The proteins of the CROWDED NUCLEI （CRWN） family are considered lamin-like candidates in Arabidopsis, although the functions of these proteins are largely unknown. In this article we show that crwnl crwn2 double mutant displays an enhanced resistance against virulent bacterial pathogens, and both virulent bacteria and salicylic acid （SA） induce transcription of CRWN1 gene as well as proteasome-mediated degradation of CRWN1 protein. We also show that CRWN1 interacts with NAC WITH TRANSMEMBRANE MOTIF1 -LIKE9 （NTL9）, a NAC transcription factor involved in plant immunity. The interaction between CRWN1 and NTL9 enhances the binding of NTL9 to the promoter of the PATHOGENESIS-RELATED1 （PR1） gene, and inhibits PR1 expression. Further genetic experiments indicated that the defense-related phenotypes of crwnl crwn2 double mutant are dependent on NONEXPRESSOR OF PR GENES1 （NPR1）, a transcriptional cofactor of PRI. These findings revealed a regulatory network composed of lamin-like protein CRWN1, NTL9, and NPR1 for the regulation of PR1 expression.

β-Glucosidase has been reported to induce the production of herbivore-induced plant volatiles. How-ever, how it works remains unclear. Here, we investigated the levels of salicylic acid (SA), jasmonic acid (JA), ethylene, and H2O2, all of which are known signaling molecules that play important roles in in-duced plant defense in rice plants treated with β-glucosidase, and compared these to levels in plants infested by the rice brown planthopper Nilaparvata lugens (Stl). Results showed that wounding and treatment by β-glucosidase increased the levels of SA, ethylene, and H2O2, but not JA, in all plants compared to control plants. The signaling pathways activated by β-glucosidase treatment are similar to those activated by an infestation by N. lugens, although the magnitude and timing of the signals elicited by the two treatments are different. This may explain why both treatments have similar volatile profiles and are equally attractive to the parasitoid Anagrus nilaparvatae Pang et Wang.

Jasmonic acid（JA） and related metabolites play a key role in plant defense and growth. JA carboxyl methyltransferase（JMT） may be involved in plant defense and development by methylating JA to methyl jasmonate（Me JA） and thus influencing the concentrations of JA and related metabolites. However, no JMT gene has been well characterized in monocotyledon defense and development at the molecular level. After we cloned a rice JMT gene,Os JMT1, whose encoding protein was localized in the cytosol, we found that the recombinant Os JMT1 protein catalyzed JA to Me JA. Os JMT1 is up-regulated in response to infestation with the brown planthopper（BPH; Nilaparvata lugens）. Plants in which Os JMT1 had been overexpressed（oeJMT plants） showed reduced height and yield. These oe-JMT plants also exhibited increased Me JA levels but reduced levels of herbivore-induced JA and jasmonoyl-isoleucine（JAIle）. The oe-JMT plants were more attractive to BPH female adults but showed increased resistance to BPH nymphs,probably owing to the different responses of BPH female adults and nymphs to the changes in levels of H_2O_2 and Me JA in oe-JMT plants. These results indicate that Os JMT1,by altering levels of JA and related metabolites, plays a role in regulating plant development and herbivore-induced defense responses in rice.

为探究2种稻飞虱——褐飞虱Nilaparvata lugens(St?l)和白背飞虱Sogatella furcifera(Horváth)诱导的水稻防御反应差异,于室内测定了水稻在分别受褐飞虱或白背飞虱产卵雌成虫为害时,其茉莉酸、水杨酸、乙烯、H_2O_2以及挥发物含量的变化。结果表明,尽管褐飞虱和白背飞虱产卵雌成虫的为害均可以诱导水稻茉莉酸、水杨酸、乙烯和H_2O_2等防御相关信号分子以及一些水稻挥发物含量的增加,但是二者的诱导作用存在差异。水稻在受白背飞虱产卵雌成虫为害时,茉莉酸的含量在3 h时就显著升高,12 h时含量达到最高;而受褐飞虱产卵雌成虫为害时,6 h时茉莉酸含量才显著升高,72 h时含量达最高;并且在2种稻飞虱为害的3～48 h内,白背飞虱为害诱导的茉莉酸含量始终显著高于褐飞虱为害诱导的。水稻受白背飞虱产卵雌成虫为害24 h后诱导的水杨酸含量、为害48 h后诱导的乙烯含量、为害72 h后诱导的H_2O_2含量及为害24 h后诱导的挥发物释放量分别是褐飞虱产卵雌成虫为害诱导的1.28、1.45、4.10和1.77倍。表明水稻能识别褐飞虱和白背飞虱的为害,从而做出针对害虫种类特异性的防御反应;并且水稻对白背飞虱产卵雌成虫为害所做出的防御反应比对褐飞虱的更强烈。
