Plants experience different abiotic/biotic stresses,which trigger their molecular machinery to cope with them. Besides general mechanisms prompted by many stresses, specific mechanisms have been introduced to optimize the response to individual threats. However, these key mechanisms are difficult to identify. Here, we introduce an in-depth species-specific transcriptomic analysis and conduct an extensive meta-analysis of the responses to related species to gain more knowledge about plant responses. The spider mite Tetranychus urticae was used as the individual species, several arthropod herbivores as the related species for meta-analysis, and Arabidopsis thaliana plants as the common host. The analysis of the transcriptomic data showed typical common responses to herbivory, such as jasmonate signaling or glucosinolate biosynthesis. Also, a specific set of genes likely involved in the particularities of the Arabidopsis-spider mite interaction was discovered. The new findings have determined a prominent role in this interaction of the jasmonateinduced pathways leading to the biosynthesis of anthocyanins and tocopherols. Therefore, tandem individual/general transcriptomic profiling has been revealed as an effective method to identify novel relevant processes and specificities in the plant response to environmental stresses.

Abscisic acid(ABA)is an important hormone that regulates both plant development and stress responses(Chen et al.,2020).In the absence of ABA,group A PROTEIN PHOSPHATASE 2Cs(PP2Cs)interact with and inhibit SUCROSE-NON-FERMENTING 1-RELATED KINASES 2(SnRK2s).When ABA is present,ABA receptor PyRABACTIN RESISTANCE 1 and PyRABACTIN RESISTANCE 1-LIKE PROTEINS bind to and inhibit PP2Cs,allowing phosphorylation and activation of SnRK2s that,in turn,phosphorylate downstream targets,such as transcription factors,ion channels,and transporters(Figure 1).

Regulation of the New Arabidopsis Imprinted Gene AtBMIIC Requires the Interplay of Different Epigenetic Mechanisms

Molecular Plant 2012年第1期5卷 260-269页

Recently, it has been shown that plants contain homologs to the animal Polycomb repressive complex I （PRC1） components BM11 and RINGIA/B. In Arabidopsis, there are three BMIl-like genes, two of which, AtBMIIA and B, are required during post-embryonic plant growth to repress embryonic traits and allow cell differentiation. However, little is known about the third BMIl-like gene, AtBMIIC. In this work, we show that AtBMIIC is only expressed during endosperm and stamen development. AtBMIIC is an imprinted gene expressed from the maternal allele in the endosperm but bialleli- cally expressed in stamen. We found that the characteristic expression pattern of AtBMIIC is the result of a complex epigenetic regulation that involves CG DNA methylation, RNA-directed non-CG DNA methylation （RdDM）, and PcG activity. Our results show the orchestrated interplay of different epigenetic mechanisms in regulating gene expression throughout development, shedding light on the current hypotheses for the origin and mechanism of imprinting in plant endosperm.

Repression of the Auxin Response Pathway Increases Arabidopsis Susceptibility to Necrotrophic Fungi

Molecular Plant 2008年第3期1卷 496-509页

In plants, resistance to necrotrophic pathogens depends on the interplay between different hormone systems, such as those regulated by salicylic acid （SA）, jasmonic acid （JA）, ethylene, and abscisic acid. Repression of auxin signaling by the SA pathway was recently shown to contribute to antibacterial resistance. Here, we demonstrate that Arabidopsis auxin signaling mutants axrl, axr2, and axr6 that have defects in the auxin-stimulated SCF （Skpl-Cullin- F-box） ubiquitination pathway exhibit increased susceptibility to the necrotrophic fungi Plectosphaerella cucumerina and Botrytis cinerea. Also, stabilization of the auxin transcriptional repressor AXR3 that is normally targeted for removal by the SCF-ubiquitin/proteasome machinery occurs upon P. cucumerina infection. Pharmacological inhibition of auxin transport or proteasome function each compromise necrotroph resistance of wild-type plants to a similar extent as in non-treated auxin response mutants. These results suggest that auxin signaling is important for resistance to the necrotro- phic fungi P. cucumerina and B. cinerea. SGTlb （one of two Arabidopsis SGT1 genes encoding HSP90/HSC70 co-chaperones） promotes the functions of SCF E3-ubiquitin ligase complexes in auxin and JA responses and resistance conditioned by certain Resistance （R） genes to biotrophic pathogens. We find that sgtlb mutants are as resistant to P. cucumerina as wild-type plants. Conversely, auxin/SCF signaling mutants are uncompromised in RPP4-triggered resistance to the obligate biotrophic oomycete, Hyaloperonospora parasitica. Thus, the predominant action of SGTlb in R gene-conditioned resis- tance to oomycetes appears to be at a site other than assisting SCF E3-ubiquitin ligases. However, genetic additivity of sgtlb axrl double mutants in susceptibility to H. parasitica suggests that SCF-mediated ubiquitination contributes to lim- iting biotrophic pathogen colonization once plant-pathogen compatibility is established.

N-Linked Glycosylation of the p24 Family Protein p24δ5 Modulates Retrograde Golgi-to-ER Transport of K/HdeL Ligands in Arabidopsis

引用

Molecular Plant 2017年第8期10卷 1095-1106页

作者： Noelia Pastor-Cantizano Maria Jesus Garcia-Murria Cesar Bernat-Silvestre Maria Jesus Marcote Ismael Mingarro Fernando Aniento departamento de Bioquimica y Biologia Molecular Universitat de Valencia 46100 Burjassot Spain Estructura de Recerca Interdisciplinar en biotecnologia i Biomedicina (ERI BIOTECMED) Universitat de Valencia 46100 Burjassot Spain

The K/HdeL receptor ERD2 mediates the transport of soluble endoplasmic reticulum （ER）-resident proteins containing a C-terminal K/HdeL signal from the Golgi apparatus back to the ER via COPI （COat Protein I）-coated vesicles. Sorting of ERD2 within COPI vesicles is facilitated by p24 proteins. In Arabidop- sis, p24δ5 has been shown to interact directly with ERD2 via its luminal GOLD （GOLgi Dynamics） domain and with COPI proteins via its cytoplasmic C-terminal tail at the acidic pH of the Golgi apparatus. Several members of the p24 family in mammals and yeast have been shown to be glycosylated, but whether Arabidopsis p24 proteins are glycosylated and the role of the sugar moiety in p24 function remain unclear. Here, we show that Arabidopsis p24δ5 protein is N-glycosylated in its GOLD domain. Furthermore, we demonstrate that this post-translational modification is important for its coupled transport with p241β2 at the ER-Golgi interface, for its interaction with the K/HdeL receptor ERD2, and for retrograde transport of ERD2 and K/HdeL ligands from the Golgi apparatus back to the ER.

In vitro germination and shoot proliferation of the threatened species Cinchona officinalis L(Rubiaceae).

引用

Journal of Forestry Research 2016年第6期27卷 1229-1236页

作者： Rosa Armijos-Gonzalez Cesar Perez-Ruiz departamento de Ciencias Naturales Universidad Tecnica Particular de LojaCP 1101 608 LojaEcuador departamento de biotecnologia y Biologia Vegetal E.T.S.Ingenieros AgronomosUniversidad Politecnica de MadridCP 728040 MadridSpain

Cinchona officinalis （Rubiaceae） is an endemic species of the Loja Valley in southern Ecuador with medicinal uses. Because of over-exploitation in the nine- teenth century and more recent disturbances to its ecosystem, C. officinalis populations are threatened. Currently, natural regeneration of the populations is low, despite its high plant regeneration and seed formation capacity. In the present study, an efficient protocol for germination, shoot proliferation and plantlets regeneration was developed for this species. Phenolic content and germination rate of C. officinalis seeds were compared with a control species, C. pubescens. Nodal segments from seedlings of C. officinalis were cultured on Gamborg medium supplemented with different combinations of plant growth regulators. Because the phenol content is high in C. officinalis, the phenolic should be removed with hydrogen peroxide or water washes to stimulate germination. Shoots and callus developed from nodal segments within 45 days using most of the tested combinations of plant growth regulators. The best rates of shoot proliferation, callus formation and adventitious buds were obtained in medium supplemented with 5.0 mg L^-1 6-benzyl-aminopurine and 3.0 mg L^-1 indole- 3-butyfic acid.
