The main defense response to Soybean mosaic virus(SMV)infection in soybean[Glycine max(L.)Merr.]is thought to be blockage of intercellular virus transport by callose deposition on plasmodesmata.But the specific regulatory mechanism remains largely unknown.In this study,we found that hydrogen peroxide(H_(2)O_(2))signal downstream of NO was associated with the regulation of callose accumulation.Abundant H_(2)O_(2)was produced on the cell membrane and cell wall in the incompatible combination of soybean cultivar Jidou 7 and SMV strain N3,whereas no obvious H_(2)O_(2)was observed in the compatible combination of Jidou 7 and strain SC-8.When H_(2)O_(2)production was inhibited,callose accumulation induced by SMV infection decreased to a level insufficient to restrict virus transport in the incompatible combination.The H_(2)O_(2)-associated transcriptome dynamics of soybean during SMV infection was investigated.Transcriptome and functional analysis using virus-induced gene silencing showed that Gm SEOB and Gm PAP27,two genes regulated by H_(2)O_(2),functioned in resistance by positively regulating the accumulation of callose in response to SMV infection.These results lay a foundation for further research on the signal transduction and molecular regulation of callose deposition during soybean resistance to SMV infection.

Extemal and internal signals can prime the plant immune system for a faster and/or stronger response to pathogen attack.β-aminobutyric acid(BABA)is an endogenous stress metabolite that induces broad-spectrum disease resistance in plants.BABA perception in Arabidopsis is mediated by the aspartyl tRNA synthetase IBI1,which activates priming of multiple immune responses,including callose-associated cell wall defenses that are under control by abscisic acid(ABA).However,the immediate signaling components after BABA perception by IBI1,as well as the regulatory role of ABA therein,remain unknown.Here,we have studied the early signaling events controlling IBI1-dependent BABA-induced resistance(BABAIR),using untargeted transcriptome and protein interaction analyses.Transcriptome analysis revealed that IBI1-dependent expression of BABA-IR against the biotrophic oomycete Hyaloperonospora arabidopsidis is associated with suppression of ABA-inducible abiotic stress genes.Protein interaction studies identified the VOZ1 and VOZ2 transcription factors(TFs)as IBI1-interacting partners,which are transcrip-tionally induced by ABA but suppress pathogen-induced expression of ABA-dependent genes.Furthermore,we show that VOZ TFs require nuclear localization for their contribution to BABA-IR by mediating augmented expression of callose-associated defense.Collectively,our study indicates that the IBI1-VOZ signaling module channels pathogen-induced ABA signaling toward cell wall defense while simultaneously suppressing abiotic stress-responsive genes.

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 K_(2)SO_(4)induced rice resistance against the root-knot nematode Meloidogyne graminicola are still lacking.In this work,K_(2)SO_(4)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(H_(2)O_(2))accumulation and increasing callose deposition.Meanwhile,galls and nematodes in rice roots were more in the potassium channel OsAKT11 and transporter OsHAK5 gene-deficient plants than in wild-type,while the K_(2)SO_(4)-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 OsPR1 a/OsPR1 b was up-regulated in rice after K_(2)SO_(4)treatment.In conclusion,K_(2)SO_(4)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.

Evidence for the Role Evolutionary Increase Yield in Cotton of Transfer Cells in the in Seed and Fiber Biomass

Transfer cells （TCs） are specialized cells exhibiting invaginated wall ingrowths （Wls）, thereby amplifying their plasma membrane surface area （PMSA） and hence the capacity to transport nutrients. However, it remains unknown as to whether TCs play a role in biomass yield increase during evolution or domestication. Here, we examine this issue from a comparative evolutionary perspective. The cultivated tetraploid AD genome species of cotton and its A and D genome diploid progenitors displayed high, medium, and low seed and fiber biomass yield, respectively. In all three species, cells of the innermost layer of the seed coat juxtaposed to the filial tissues trans-differentiated to a TC morphology. Electron microscopic analyses revealed that these TCs are characterized by sequential formation of flange and reticulate Wls during the phase of rapid increase in seed biomass. Significantly, TCs from the tetraploid species developed substantially more flange and reticulate Wls and exhibited a higher degree of reticulate WI formation than their progenitors. Consequently, the estimated PMSA of TCs of the tetraploid species was about 4 and 70 times higher than that of TCs of the A and D genome progenitors, respectively, which correlates positively with seed and fiber biomass yield. Further, TCs with extensive Wls in the tetraploid species had much stronger expression of sucrose synthase, a key enzyme involved in TC Wl formation and function, than those from the A and D progenitors. The analyses provide a set of novel evidence that the development of TC Wls may play an important role in the increase of seed and fiber biomass yield through polyploidization during evolution.

Integrating Hormone- and Micromolecule- Mediated Signaling with Plasmodesmal Communication

引用

Intercellular and supracellular communications through plasmodesmata are involved in vital processes for plant development and physiological responses. Micro- and macromolecules, including hormones, RNA, and proteins, serve as biological information vectors that traffic through the plasmodesmata between cells. Previous studies demonstrated that the plasmodesmata are elaborately regulated, whereby a long queue of multiple signaling molecules forms. However, the mechanism by which these signals are coupled or coor- dinated in terms of simultaneous transport in a single channel remains a puzzle. In the last few years, several phytohormones that could function as both non-cell-autonomous signals and plasmodesmal regulators have been disclosed. Plasmodesmal regulators such as auxin, salicylic acid, reactive oxygen species, gibberellic acids, chitin, and jasmonic acid could regulate intercellular trafficking by adjusting plasmodesmal permeability. Here, callose, along with β-glucan synthase and β-glucanase, plays a critical role in regulating plasmodesmal permeability. Interestingly, most of the previously identified regulators are capable of diffusing through the plasmodesmata. Given the small sizes of these molecules, the plasmo- desmata are prominent intercellular channels that allow diffusion-based movement of those signaling molecules. Obviously, intercellular communication is under the control of a major mechanism, named a feedback loop, at the plasmodesmata, which mediates complicated biological behaviors. Prospective research on the mechanism of coupling micromolecules at the plasmodesmata for developmental signaling and nutrient provision will help us to understand how plants coordinate their development and photosynthetic assimilation, which is important for agriculture.

Citrus Huanglongbing,associated with Candidatus Liberibacter asiaticus(Las),is the serious disease of citrus worldwide.Here,we compared differences between leaf and root responses in Wanjincheng Orange(Citrus sinensis Osbeck)to Las infection using leaf-disc grafting.Trees had no obvious symptoms in the first two months after grafting(MAG),but yellowing leaves,thickened midribs and decayed roots began to appear at 6 MAG.The Las growth rate in roots was greater than inmidribs from 2 to 6 MAG;however,by 10 MAG,it was significantly lower in roots than in midribs.Amicroscopic analysis revealed that starch accumulation,callose deposition,cellwall thickness and the number of cell layers increased in the phloem of infected trees.After Las infection,the starch content in the leaves was significantly higher than that in the roots,while the callose deposition in the midribs was 3–19 times that in the roots.A gene expression analysis showed that transcripts of callose-and starch metabolism-related genes were obviously affected by Las infection,and the pathogenesis-related genes PR1,PR2 and PR5 were significantly upregulated and downregulated in midrib and root,respectively.Our results indicated that the PR-mediated resistance response was repressed in root but activated in midrib,which may result in the more rapid Las growth in roots than in midribs during the early infection stage.

Cytological and Molecular Characteristics of Pollen Abortion in Lily with Dysplastic Tapetum

Lily was grown worldwide as a fresh cutting flower because of its colorful petals, but its anther contained a large number of pollen grains that cause serious pollen contamination, however, pollen abortion can effectively reduce the level of pollen pollution. Our analysis aims to use cytological observation to detect the critical stage when pollen abortion occurs and to provide comprehensive gene expression information at the transcriptional level. The result showed that pollen abortion in ‘Little Kiss’ began at the mononuclear stage and the callose that covers the microspores failed to degenerate when young pollens were released from the tetrads. In addition, compared with the normally developed one,the tapetum of ‘Little Kiss’ degraded in advance while the degradation of callose was delayed. Furthermore, 103 differentially expressed genes(DEGs) related to the advance degeneration of tapetum cells and callose were found in the expression levels, including 22 transcription factors(TFs). In particular, two β-glucanase genes(endo-1,3(4)-β-glucanase, exo-β-glucanase) responsible for callose degeneration were significantly down-regulated. These results suggested that pollen abortion may occur at mononuclear stage and that early degeneration of tapetum cells resulted in a significant down-regulation of β-glucanase genes. As a result, the callose to cover microspores impedes the formation of pollen walls, which may possibly lead to pollen abortion.

Transient expression of the <i>Arabidopsis thaliana</i>callose synthase PMR4 increases penetration resistance to powdery mildew in barley

引用

Advances in Bioscience and Biotechnology 2013年第8期4卷 810-813页

Localized cell wall thickenings, so called papillae, are a common plant defense response to fungal attack at sites of penetration of the plant cell. The major constituent of papillae is callose, a (1,3)-β-glucan polymer, which contributes to slowing or blocking the invading fungal hyphae. In the model plant Arabidopsis thaliana, we could recently show that the overexpression of PMR4(POWDERY MILDEW RESITANT 4), which encodes a stress induced callose synthase, results in complete powdery mildew resistance. To evaluate if these findings are also transferable to monocot crops, we transiently expressed PMR4 under control of the 35S promoter in leaves of barley (Hordeum vulgare) seedlings, which were subsequently inoculated with the virulent powdery mildew Blumeria graminis f. sp. hordei. Fusion of the green fluorescent protein (GFP) to PMR4 allowed the identification of successfully transformed barley cells, which showed an increased penetration resistance to B. graminis compared to control cells that express only GFP.PMR4-GFP localized in a similar pattern at the site of attempted fungal penetration as observed inA. thaliana, which suggests that similar transport mechanisms of the callose synthase might exist in dicot and monocot plants.

Cell wall is a fundamental plant constituent,rigid but plastic,which provides structural support for plant development and diverse cell shape formation.Cell wall is composed of the polysaccharides cellulose,hemicellulose,pectin andlignin,meanwhile residues a large number of glycoproteins.Several glycosylphosphatidylinositol(GPI)-anchored glycoproteins have been described as important regulators for cell wall formation,while the underlying mechanism is poorly understood.Here,we identify a glycosylphosphatidylinositol(GPI)-anchored glycoprotein SKU5,as well as its homolog SKU5-similar 1(SKS1),which are highly co-expressed with cell wall regulatory genes at transcription level.Further studies show thatsku5 sks1 double mutant decreases crystallized cellulose level while elevates callose deposition along the cell wall at the epidermis-cortex junction area,consequently exhibiting pronounced cell wall protrusion.As multi-copper oxidases,SKU5 and SKS1 might function as cell wall ferroxidase to regulate iron homeostasis,leading to the unexpected callose deposition;meanwhile,GPI anchor motifs are dispensable for the location and functionality of SKU5/SKS1.This study unveils a novel regulatory module of cell wall pattern formation,by which SKU5 and SKS1 coordinate CESA-dependent cellulose synthesis as well as iron-dependent callose deposition,which helps more insights into the mechanism of plant cell shape formation.
