Five novel triazole compounds containing group 1,3-dioxolane were designed and synthesized by taking difenoconazole as the start compound and changing diphenyl ether for benzyl phenyl ether. Their structures were confirmed by elemental analyses, ()~1H NMR and IR spectra. The single crystal structure of 2-[4-(2,4-dichlorophenylmethoxy]phenyl-2-(1,2,4-triazol-1-yl)methane-1,3-dioxolane was determined by means of (X-ray) diffraction. The preliminary bioassays showed that the synthesized compounds exhibited some activities of fungicides and plant growth regulators.

Zeolite imidazole frameworks(ZIFs),a class of the metal organic framework,have been extensively studied in environmental ***,their environmental fate and potential ecological impact on plants remain ***,we investigated the phytotoxicity,transformation,and bioaccumulation processes of two typical ZIFs(ZIF-8 and ZIF-67)in rice(Oryza sativa L.)under hydroponic ***-8 and ZIF-67 in the concentration of 50 mg/L decreased root and shoot dry weight maximally by 55.2%and 27.5%,53.5%and 37.5%,*** scanning electron microscopy(SEM)imaging combined with X-ray diffraction(XRD)patterns revealed that ZIFs on the root surface gradually collapsed and transformed into nanosheets with increasing cultivation *** fluorescein isothiocyanate(FITC)labeled ZIFs were applied to trace the uptake and translocation of ZIFs in *** results demonstrated that the transformed ZIFs were mainly distributed in the intercellular spaces of rice root,while they cannot be transported to culms and *** so,the Co and Zn contents of rice roots and shoots in the ZIFs treated groups were increased by 1145%and 1259%,145%and 259%,respectively,compared with the control *** findings suggested that the phytotoxicity of ZIFs are primarily attributed to the transformed ZIFs and to a less extent,the metal ions and their ligands,and they were internalized by rice root and increased the Co and Zn contents of *** study reported the transformation of ZIFs and their biological effectiveness in rice,highlighting the potential environmental hazards and risks of ZIFs to crop plants.

Cadmium(Cd)pollution poses a serious threat to plant growth and *** have shown great application potential for alleviation of Cd toxicity to *** this study,we applied graphitic carbon nitride nanosheets(g-C_(3)N_(4)NSs)for alleviation of Cd-toxicity to soybean(Glycine max L.).The g-C_(3)N_(4)NSs supplementation significantly improved plant growth and reduced oxidative damage in the Cd-toxicated soybean seedlings through hydroponic ***,the g-C_(3)N_(4)NSs dynamically regulated the root cell wall(RCW)components by increasing pectin content and modifying its demethylation via enhancing pectin methylesterase(PME)activity,therefore greatly enhanced stronger RCW-Cd retention(up to 82.8%)and reduced Cd migration to the ***,the g-C_(3)N_(4)NSs reversed the Cd-induced chlorosis,increased photosynthetic efficiency because of enhancement in F_v/F_mration,Y(Ⅱ)and sugars *** results provide new insights into the alleviation of Cd toxicity to plants by g-C_(3)N_(4)NSs,and shed light on the application of low-cost and environmental-friendly carbon-based NMs for alleviating heavy metal toxicity to plants.

Despite extensive studies on cultivated rice, the population structure and genetic diversity of the indica photoperiod-and thermo-sensitive genic male sterility(P/TGMS) lines in China remains unclear. Using 48 simple sequence repeat(SSR) markers, we genotyped a panel of 208 indica P/TGMS lines and confirmed three subgroups, named indica-I, indica-II and indica-III, in indica P/TGMS lines. Further diversity analysis indicated indica-II had the highest genetic diversity. The genetic differentiation between indica-II and indica-III was demonstrated as the largest among the three subgroups. Moreover, indica/japonica component identification was detected that five P/TGMS lines possess indica components less than 0.900. These results improve our knowledge on the genetic background for P/TGMS lines in China and will be beneficial for hybrid rice breeding programs.

异型株是水稻品种试验的重要判定指标,虽在新品种特异性、一致性和稳定性测试、品种纯度鉴定、种子繁育、品种区域试验中已有相关定义,但在实际操作中仍有较大的歧义。本文对异型株在不同品种试验中的概念进行辨析,旨在准确把握异型株的判定,提高水稻品种试验的准确性,避免因误判而导致的品种授权、种子质量、品种审定等问题。另外,本文提出加快DNA指纹检测技术在异型株判定中的应用,以确保品种试验的质量。

为探明甜樱桃内生细菌种群结构及多样性,以‘砂蜜豆’甜樱桃根、主干树皮和枝条3个组织的内生细菌为研究对象,对其16S rRNA V3~V4区进行高通量测序。结果表明,‘砂蜜豆’甜樱桃不同组织内生细菌群落多样性及功能存在较大差异。不同组织中共获得有效序列9665813条,聚类为1386个OTU(operational taxonomic units),隶属于20个门、43个纲、79个目、162个科和346个属。在门水平,变形菌门(Proteobacteria)在各组织中的丰度均最高,是最优势菌门。在属水平,根部内生细菌的优势菌属为链霉菌属(Streptomyces)、类固醇杆菌属(Steroidobacter)和乳酸杆菌属(Lactobacillus);枝条内生细菌中鞘氨醇单胞菌(Sphingomonas)的相对丰度较高;主干树皮内生细菌的优势菌属为拟杆菌属(Bacteroides)。PICRUSt(phylogenetic investigation of communities by reconstruction of unobserved states)基因预测表明,内生细菌功能主要涉及多糖、萜类和酮类、酶及维生素等次生代谢产物的生物合成。综上所述,甜樱桃内生细菌具有丰富的种群多样性,为今后开发利用甜樱桃内生细菌资源奠定了基础。
