Potassium (K), an important nutrient element, can improve the stress resistance/tolerance of crops. The application of K in resisting plant-parasitic nematodes shows that the K treatment can reduce the occurrence of nematode diseases and increase crop yield. However, data on K2SO4 induced rice resistance against the root-knot nematode Meloidogynegraminicola are still lacking. In this work, K2SO4 treatment reduced galls and nematodes in rice plants and delayed the development of nematodes. Rather than affecting the attractiveness of roots to nematodes and the morphological phenotype of giant cells at feeding sites, such an effect is achieved by rapidly priming hydrogen peroxide (H2O2) accumulation and increasing callose deposition. Meanwhile, galls and nematodes in rice roots were more in the potassium channel OsAKT1 and transporter OsHAK5 gene-deficient plants than in wild-type, while the K2SO4-induced resistance showed weaker in the defective plants. In addition, during the process of nematode infection, the expression of jasmonic acid (JA)/ethylene (ET)/brassinolide (BR) signaling pathway-related genes and pathogenesis-related (PR) genes OsPR1a/OsPR1b was up-regulated in rice after K2SO4 treatment. In conclusion, K2SO4 induced rice resistance against M. graminicola. The mechanism of inducing resistance was to prime the basal defense and required the participation of the K+ channel and transporter in rice. These laid a foundation for further study on the mechanism of rice defense against nematodes and the rational use of potassium fertilizer on improving rice resistance against nematodes in the field. 相似文献

动物线虫抗药机制研究进展 总被引:2,自引:0,他引:2
[目的]克服由于驱寄生虫药物抗药性的产生而严重制约世界畜牧业发展的问题。[方法]介绍动物线虫对苯并咪唑类、咪唑并噻唑类和大环内酯抗生素类3类驱虫药物的抗药机制的研究进展。[结果]动物寄生线虫对驱虫药的抗药机制主要是在线虫与药物选择压力的共同作用下,首先发生于药物受体基因的点突变,使其编码的药物受体结构改变而引起与药物的作用效应发生不同程度的变化,线虫获得一定的抗药性并将这些抗药基因变异遗传。[结论]动物线虫抗药机制的研究对控制线虫的感染和准确检测线虫抗药性均有重要意义。 相似文献

Plant-parasitic nematodes cause substantial economic losses to global agriculture yearly. The use of nematicides is an effective way of controlling plant-parasitic nematodes. However, the long-term use of traditional organophosphorus and carbamate chemical nematicides can lead to increased nematode resistance. With the increasing awareness of the necessity for the protection of the environment and human health, highly toxic nematicides no longer meet the developmental requirements of modern agriculture. Recently, many studies have been undertaken on the isolation and nematicidal activity of natural products against plant-parasitic nematodes and Caenorhabditis elegans. As an important model nematode, C. elegans plays a vital reference role in studying plant-parasitic nematodes regarding nematicidal activity, metabolic mechanism, and modes of action and target. We reviewed the latest research progress of natural nematicidal active compounds against plantparasitic nematodes and C. elegans over the past ten years, discussed the structure-activity relationship and mechanism of action, and examined the development and application of natural nematicidal active compounds. 相似文献

为了解内蒙古地区放牧绵羊胃肠道线虫对常用驱虫药物的耐药情况,选取呼和浩特和林格尔地区和包头萨拉齐地区自然状态下,感染胃肠道线虫的放牧绵羊各60只,随机分为3组,每组20只,其中2个试验组分别采用伊维菌素或丙硫咪唑进行驱虫,对照组则不做处理,采用粪便虫卵减少试验方法,对其驱虫效果进行评估。结果表明:和林格尔地区绵羊胃肠道线虫使用伊维菌素或丙硫咪唑处理72 h后,粪便虫卵减少率分别是28%和77%;萨拉齐地区绵羊粪便虫卵减少率分别是40%和100%。研究发现:两地区放牧绵羊胃肠道线虫对伊维菌素有着较高的耐药性;和林格尔地区绵羊对丙硫咪唑耐药性程度较轻;在萨拉齐地区,丙硫咪唑驱虫效果较好。 相似文献
