目的观察JAS踝关节训练器联合综合康复对创伤性踝关节僵硬患者的康复影响。方法选取因骨折术后造成踝关节僵硬患者40倒，随机分为综合康复组和JAS组，各20例。两组均予物理因子、功能训练、关节松动术等综合康复疗法，JAS组在此基础上采用JAS踝关节训练器治疗。分别于治疗前、治疗10周后对患者进行AOFAS踝一后足评分和踝关节主动活动度（AROM）评定。结果两组患者治疗10周后，踝关节AROM和AOFAS踝-后足评分均较治疗前提高，差异有统计学意义（P〈0．05），且JAS组患者踝关节AROM、AOFAS踝-后足评分比综合康复组有更明显的改善，差异有统计学意义（P〈0．05）。结论JAS踝关节训练器联合综合康复能够有效改善创伤性踝关节僵硬，促进踝关节功能恢童。

JAS COAT固化剂对磷石膏环境风险的影响

磷石膏是湿法生产磷酸的副产物,大量堆存的磷石膏给环境造成了巨大的压力。通过室内理化性质试验研究了JAS COAT固化剂对磷石膏性能的改良,优选出适宜的JAS COAT固化剂掺量及含水率,并对稳定化机理进行了探讨。结果表明,加水及固化剂不能改变磷石膏中重金属的总量,但明显降低了浸出液中重金属的质量浓度;固化剂掺量为3%~5%时,磷石膏的放射性随含水率增加呈先减小后增大的趋势。

Effects of Exogenous Jasmonic Acid on Concentrations of Direct-Defense Chemicals and Expression of Related Genes in Bt (Bacillus thuringiensis) Corn (Zea mays)

Bt corn is one of the top three large-scale commercialized transgenic crops around the world. It is increasingly clear that the complementary durable approaches for pest control, which combine the endogenous defense of the crop with the introduced foreign genes, are promising alternative strategies for pest resistance management and the next generation of insect-resistant transgenic crops. In the present study, we tested the inducible effects of exogenous jasmonic acid （JA） on direct-defense chemical content, Bt protein concentration, and related gene expression in the leaves of Bt corn cultivar 34B24 and non-Bt cultivar 34B23 by chemical analysis, ELISA, and RT-PCR. The results show that the expression of LOX, PR-2a, MPI, and PR-I genes in the treated leaf （the first leaf） was promoted by exogenous JA both in 34B24 and 34B23. As compared with the control, the concentration of DIMBOA in the treated leaf was significantly increased by 63 and 18% for 34B24 and 34B23, respectively. The total phenolic acid was also increased by 24 and 12% for both 34B24 and 34B23. The Bt protein content of 34B24 in the treated leaf was increased by 13% but decreased significantly by 27% in the second leaf. The induced response of 34B24 was in a systemic way and was much stronger than that of 34B23. Those findings indicated that there is a synergistic interaction between Bt gene and internally induced chemical defense system triggered by externally applied JA in Bt corn.

Silencing JA hydroxylases in Nicotiana attenuata enhances jasmonic acid-isoleucine-mediated defenses against Spodoptera litura

Jasmonic acid(JA)plays important roles in plant resistance to insect herbivores.One important derivative of JA is 12-OH-JA,which is produced by two independent pathways:direct hydroxylation of JA by jasmonate-induced oxygenases(JOXs)or hydrolyzation of 12-OH-JA-Ile.Yet the function of 12-OH-JA in plant-herbivore interactions remains largely unknown.In this study,we silenced four JOX homologs independently in the wild tobacco Nicotiana attenuata by virus-induced gene silencing(VIGS),and found that all four JOX homologs are involved in JA hydroxylation.Simultaneously silencing the four JA hydroxylases in VIGS-NaJOXs plants decreased herbivory-induced 12-OH-JA by 33%,but JA and JA-Ile levels increased by 45%and 30%,respectively,compared to those in control plants.Compared to direct hydroxylation from JA,hydrolyzation from 12-OH-JA-Ile is equally important for herbivory-induced 12-OHJA accumulation:in the 12-OH-JA-Ile deficient irJAR4/6 plants,12-OH-JA decreased 34%.Moreover,VIGSNaJOXs plants exhibited enhanced resistance to the generalist herbivore Spodoptera litura.The poor larval performance was strongly correlated with high levels of several JA-Ile-dependent direct defense metabolites in the VIGS-NaJOXs plants.When we simultaneously silenced all four JA hydroxylases in the JAIle-deficient irJAR4/6 background,the enhanced herbivore resistance diminished,demonstrating that enhanced herbivore resistance resulted from elevated JA-Ile levels.Given that silencing these NaJOX-like genes did not detectably alter plant growth but highly increased plant defense levels,we propose that JOX genes are potential targets for genetic improvement of herbivore-resistant crops.

Phytochrome B regulates jasmonic acid-mediated defense response against Botrytis cinerea in Arabidopsis

The phytochrome B mediated light signaling integrates with various phytohormone signalings to control plant immune response.However,it is still unclear whether phyB-mediated light signaling has an effect on the biosynthesis of jasmonate during plant defense response against Botrytis cinerea.In this study,we demonstrated that phyB-mediated light signaling has a role in this process.Initially,we confirmed that phyb plants were obviously less resistant to B.cinerea while phyB overexpressing plants showed significantly enhanced resistance.We also found that the expression of numerous JA biosynthesis genes was promoted upon treatment with red or white light when compared to that of darkness,and that this promotion is dependent on phyB.Consistent with the gene expression results,phyb plants accumulated reduced pool of JA-lle,indicating that phyB-mediated light signaling indeed increased JA biosynthesis.Further genetic analysis showed that light-mediated JAZ9 degradation and phyB-enhanced resistance were dependent on the receptor COI1,and that pifl/3/4/5(pi/q)can largely rescue the severe symptom of phyb.Taken together,our study demonstrates that phyB may participate in plant defense against B.cinerea through the modulation of the biosynthesis of JA.

Botrytis cinerea-induced F-box protein 1 enhances disease resistance by inhibiting JAO/JOX-mediated jasmonic acid catabolism in Arabidopsis

Jasmonic acid(JA)is a crucial phytohormone that regulates plant immunity.The endogenous JA level is determined by the rates of its biosynthesis and catabolism in plants.The activation of JA biosynthesis has been well documented;however,how plants repress JA catabolism upon pathogen infection remains elusive.In this study,we identified and characterized Botrytis cinerea-induced F-box protein 1(BFP1)in Arabidopsis.The expression of BFP1 was induced by B.cinerea in a JA signaling-dependent manner,and BFP1 protein was critical for plant defense against B.cinerea and plant response to JA.In addition,BFP1 overexpression increased plant defenses against broad-spectrum pathogens without fitness costs.Further experiments demonstrated that BFP1 interacts with and mediates the ubiquitination and degrada-tion of jasmonic acid oxidases(JAOs,also known as jasmonate-induced oxygenases,JoXs),the enzymes that hydroxylate JA to 12OH-JA.Consistent with this,BFP1 affects the accumulation of JA and 12OH-JA during B.cinerea infection.Moreover,mutation of JAo2 complemented the phenotypes of the bfp1 mutant.Collectively,our results unveil a new mechanism used by plants to activate immune responses upon path-ogeninfection:suppressing JA catabolism.

IbNIEL-mediated degradation of IbNAC087 regulates jasmonic acid-dependent salt and drought tolerance in sweet potato

Sweet potato(Ipomoea batatas[L.]Lam.)is a crucial staple and bioenergy crop.Its abiotic stress tolerance holds significant importance in fully utilizing marginal lands.Transcriptional processes regulate abiotic stress responses,yet the molecular regulatory mechanisms in sweet potato remain unclear.In this study,a NAC(NAM,ATAF1/2,and CUC2)transcription factor,IbNAC087,was identified,which is commonly upregulated in salt-and drought-tolerant germplasms.Overexpression of IbNAC087 increased salt and drought tolerance by increasing jasmonic acid(JA)accumulation and activating reactive oxygen species(ROS)scavenging,whereas silencing this gene resulted in opposite phenotypes.JA-rich IbNAC087-OE(overexpression)plants exhibited more stomatal closure than wild-type(WT)and IbNAC087-Ri plants under NaCl,polyethylene glycol,and methyl jasmonate treatments.IbNAC087 functions as a nuclear transcriptional activator and directly activates the expression of the key JA biosynthesisrelated genes lipoxygenase(IbLOX)and allene oxide synthase(IbAOS).Moreover,IbNAC087 physically interacted with a RING-type E3 ubiquitin ligase NAC087-INTERACTING E3 LIGASE(IbNIEL),negatively regulating salt and drought tolerance in sweet potato.IbNIEL ubiquitinated IbNAC087 to promote 26S proteasome degradation,which weakened its activation on IbLOX and IbAOS.The findings provide insights into the mechanism underlying the IbNIEL-IbNAC087 module regulation of JA-dependent salt and drought response in sweet potato and provide candidate genes for improving abiotic stress tolerance in crops.
