[Objectives]The paper was to screen and identify the control effect of resistant rootstock on jujube witches broom disease.[Methods]The seeds or branches of disease-free plants were collected from wild jujube bushes infected by witches broom disease,and 5434 seedlings were obtained by sowing or cutting.The virus was inoculated by grafting diseased bark.After 6 years of preliminary screening,40 plants with resistance to jujube witches broom disease were obtained.Taking these resistant plants as the rootstocks,the susceptible variety‘long red jujube’was grafted at a height of 40 cm.When the plants grew to appropriate thickness,diseased bark was grafted to‘long red jujube’and rootstock to transmit the virus.After 18 years of observation and judgment,4 rootstock strains with high resistance or immunity to jujube witches broom disease were finally determined,namely 90801,90803,90806 and 908011.The susceptible variety‘long red jujube’was grafted to 4 rootstocks and inoculated the virus through diseased bark grafting method.[Results]The resistant rootstock had obvious disease resistance effect.When the branches of 90801 and 90803 rootstocks were grafted to the trunk of diseased trees,the symptoms of jujube witches broom disease gradually alleviated till disappeared.[Conclusions]Using germplasm with high resistance or immunity to jujube witches broom disease as rootstock can effectively prevent the spread of jujube witches broom disease,and bridging the trunk of diseased trees with branches from resistant rootstock has certain therapeutic effect. 展开更多

This paper dealt with the SDS polyacrymide gel electrophoresis of proteins ahd analysis of the amino acids in the diseasedand healthy leaves with the same strain respectively, which were at the same side and height, of Paulownia catalpifolia, P. elongata, P. albiphloea and P. kauakamii respectively. The results indicated that the leaves of 4 species of Paulownia trees with witches’ broom had one protein band, of which molecular weight was 12 kD, which did not appear in the healthy leaves free of phytoplasmas. Moreover, the protein quantity in the affected leaves was more than that in the healthy leaves free of phytoplasmas, At the same time, there was significant difference on the amino acids between the healthy and diseased leaves of P. catalpifolia and P. kawakamii. The amount of cystine in the affected leaves was higher than that in the healthy leaves, but the change of amount of phenylalanine in the affected and healthy leaves was contrary.These changes of proteins and amino acids in the leaves might be related to the witches’ broom of the Parlounia trees. 展开更多

In 2021,the Shanting District Fruit Industry Service Center conducted an application test of a treatment for jujube witches broom disease using Changyun jujube.The results demonstrated that when diseased Changhong jujube plants were grafted with Changyun jujube in the spring using bark or cleft grafting,the majority of the new shoots of Changyun jujube exhibited no symptoms of witches broom disease,while a few exhibited symptoms of the disease.With the growth of new shoots,the symptoms of witches broom disease gradually abated,returning to normal growth and development.Similarly,the symptoms of witches broom disease on the rootstock below the grafting mouth also gradually abated,returning to normal.The Changyun jujube rootstock was utilized as the intermediate rootstock to grafting the jujube cultivars Qiyuexian and Fucuimi.The two cultivars were subsequently affixed with branch bark from the witches broom disease.The two cultivars did not exhibit any symptoms of witches broom disease,thus providing an opportunity to investigate potential treatments for this disease in jujube.Finally,the cultivation techniques of the Changyun jujube were presented. 展开更多

Somatic embryogenesis receptor-like kinases(SERKs)are receptor-like proteins that contain leucine-rich repeats and are involved in various signaling pathways.This study identified SERK family members in the Paulownia fortunei genome and analyzed their characteristics and expression profiles using bioinformatics methods.We identified 12 SERK genes with relatively conserved gene structures and motifs that were distributed unevenly on eight Paulownia chromosomes.The gene promoters contained various cis-acting elements that regulated the expression of the PfSERK genes in response to hormones and abiotic stresses.Synteny analysis indicated that 10 segmental duplication events had occurred during evolution of the PfSERK family.The expression profile of PfSERKs in various tissues of Paulownia fortunei was detected by quantitative real-time PCR(qRT-PCR).Many PfSERK genes can respond to drought and salt stress.Combined with RNA-seq and protein interaction network,it is speculated that PfSERK3/11 may participate in the occurrence of Paulownia witches’broom(PaWB)by regulating the plant height of Paulownia. 展开更多

Alternate Reality of the Lady of Shalott

The Lady of Shalott is considered to be one of Alfred Lord Tennyson’s masterpieces.The poem conversely demonstrates art and life,the aesthetic and the political,are fully interwoven:the involvement in the social world which is symbolically the destination of the Lady in the poem.The Lady who is the emblem of such an artwork can be ascribed qualities,for instance,self-containment,objectified otherness,removal from the fluidity of life,and participation in a higher order of existence,for which it is autonomy.Kermode points out that“the Romantic artwork often identifies itself with an emblematic image of autonomy and femininity”,inextricably interlinked.Her mirror shows her only“Shadows of the world”.The Lady’s web flies“Out”and floats“wide”when she“turns round”with“that desire of making an impression upon another mind”,when she seeks to address Lancelot.The mirror reconnects the Lady’s art to the real world beyond her window.Though the artist is unable to see it during the process of production,her artistic web,once out in a wider space than the tower and freed from the loom,is a true representation of outward things,the actions,and events of Camelot.This paper examines that the traditional referentiality of Tennyson’s‘The Lady of Shalott’can be better understood by supplementing the poet’s medieval sources,of little more than tangential relevance to the poem,with Homeric influences.The poem is similar to a fairytale,however,I have given an alternate reality of the Lady of Shallot in my version of a fairytale,where the characters remain the same but the fairytale takes a happy ending rather than a tragic death.My version is different from Tennyson’s since I believe the lady deserves to be jovial.Sir Lancelot was unaware of her fascination and feelings for him,as she could hardly express her feelings due to her imprisonment.She is so taken by him that she stops her work and looks at Camelot,though she risks the mysterious curse.The mirror breaks and her web magically floats out of the window on its own.She realizes that she is cursed. 展开更多

The Malleus Maleficarum(1486)by Henry Institoris and Jacques Sprenger was written in order to help inquisitors identify,persecute,and prosecute witches.The book is well-known but not studied as much as one could think,and is sometimes confused with another treatise written in 1669,which includes works by demonologists,such as Jean Nider,Bernard Basin,and Bartolomeo de Spina.This can be explained by the fact that several successive editions were published,which changed the essence of the first essay,until the 17th century.My argument is that the first edition was paradoxical and not as strict as one could imagine.The book was a“bible”for the inquisition about the subjugation of witches,but in the same way,the book seemed to be far too rationalistic when confronted with satanism and superstition.Indeed,we believe that the thesis of the Malleus Maleficarum was also a new way of conceiving of knowledge,fighting against superstition by using the tools of early rationalism at the end of the 15th century.The witches’knowledge that is investigated in the book is confronted with theology,as well as with reason.There is significant evidence of the writers’rationalistic view about occultism and belief. 展开更多
