(IF 3.696) Pub Date : 2020-10-02 Fen Wang; Weida Gao; Jiaying Sun; Xiuwen Mao; Kexin Liu; Jingru Xu; Dandan Fu; Mingyue Yuan; Hongchuan Wang; Nan Chen; Shuqin Xiao; Chunsheng Xue
The role of NADPH oxidases (NOXs) in pathogenesis and development in the Curvularia leaf spot agent Curvularia lunata remains poorly understood. In this study, we identified C. lunata ClNOX2, which localized to the plasma membrane and was responsible for reactive oxygen species (ROS) generation. Scavenging the ROS production inhibited the conidial germination and appressorial formation. The ClNOX2

Molecular characterization of pathogen-inducible bi-directional promoter from hot pepper (Capsicum annuum). Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-10-02 Solhee In,Hyunah Lee,Jongchan Woo,Eunsook Park,Doil Choi
In hot pepper, the sesquiterpene phytoalexin capsidiol is catalyzed by the two final-step enzymes, a sesquiterpene cyclase (EAS) and a hydroxylase (EAH), which are genetically linked and present as head-to-head orientation in the genome. Transcriptomic analysis revealed that a subset of EAS and EAH is highly induced following pathogen infection, suggesting the coregulation of EAS and EAH by a potential

Identification of Differentially Methylated miRNA Genes During Compatible and Incompatible Interactions Between Soybean and Soybean Cyst Nematode. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-09-24 Aditi Rambani,Yanfeng Hu,Sarbottam Piya,Miao Long,J Hollis Rice,Vince Pantalone,Tarek Hewezi
DNA methylation is a widespread epigenetic mark that affects gene expression and transposon mobility during plant development and stress responses. However, the role of DNA methylation in regulating the expression of microRNA (miRNA) genes remains largely unexplored. Here, we analyzed DNA methylation changes of miRNA genes using a pair of soybean (Glycine max) near-isogenic lines (NILs) differing in

A Viable New Strategy for the Discovery of Peptide Proteolytic Cleavage Products in Plant-Microbe Interactions. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-08-17 Manuel I Villalobos Solis,Suresh Poudel,Clemence Bonnot,Him K Shrestha,Robert L Hettich,Claire Veneault-Fourrey,Francis Martin,Paul E Abraham
Small peptides that are proteolytic cleavage products (PCPs) of less than 100 amino acids are emerging as key signaling molecules that mediate cell-to-cell communication and biological processes that occur between and within plants, fungi, and bacteria. Yet, the discovery and characterization of these molecules is largely overlooked. Today, selective enrichment and subsequent characterization by mass

Cloning of the Rice Xo1 Resistance Gene and Interaction of the Xo1 Protein with the Defense-Suppressing Xanthomonas Effector Tal2h. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-09-02 Andrew C Read,Mathilde Hutin,Matthew J Moscou,Fabio C Rinaldi,Adam J Bogdanove
The Xo1 locus in the heirloom rice variety Carolina Gold Select confers resistance to bacterial leaf streak and bacterial blight, caused by Xanthomonas oryzae pv. oryzicola and X. oryzae pv. oryzae, respectively. Resistance is triggered by pathogen-delivered transcription activator-like effectors (TALEs) independent of their ability to activate transcription and is suppressed by truncated variants

Identification of the Regulatory Components Mediated by the Cyclic di-GMP Receptor Filp and Its Interactor PilZX3 and Functioning in Virulence of Xanthomonas oryzae pv. oryzae. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-09-03 Muhammad Umar Shahbaz,Shanshan Qian,Fei Yun,Jie Zhang,Chao Yu,Fang Tian,Fenghuan Yang,Huamin Chen
The degenerate GGDEF/EAL domain protein Filp was previously shown to function as a cyclic di-GMP (c-di-GMP) signal receptor through its specific interaction with an atypical PilZ domain protein PilZX3 (formerly PXO_02715) and that this interaction is involved in regulating virulence in Xanthomonas oryzae pv. oryzae. As a step toward understanding the regulatory role of Filp/PilZX3-mediated c-di-GMP

Development of a Reverse Genetic System for Studying Rose Rosette Virus in Whole Plants Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-08-20 Jeanmarie Verchot; Venura Herath; Cesar D. Urrutia; Mathieu Gayral; Kelsey Lyle; Madalyn K. Shires; Kevin Ong; David Byrne
Rose rosette virus (RRV) is a negative-sense RNA virus with a seven-segmented genome that is enclosed by a double membrane. We constructed an unconventional minireplicon system encoding the antigenomic (ag)RNA1 (encoding the viral RNA-dependent RNA polymerase [RdRp]), agRNA3 (encoding the nucleocapsid protein [N]), and a modified agRNA5 containing the coding sequence for the iLOV protein in place of

Bacillus pumilus LZP02 Promotes Rice Root Growth by Improving Carbohydrate Metabolism and Phenylpropanoid Biosynthesis. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-08-11 Hong Liu,Zhigang Wang,Weihui Xu,Jin Zeng,Lixin Li,Shenglin Li,Zheng Gao
Elucidation of the underlying mechanisms of plant growth promotion of rhizobacteria is very important. This study explored the mechanism by which Bacillus pumilus LZP02 promotes growth in rice roots through proteomic, transcriptomic, and metabolomic techniques. The results showed that B. pumilus LZP02 promoted the absorption of phosphorous, calcium, and magnesium ions by colonization of rice roots

Rhizobial Microsymbionts of Kamchatka Oxytropis Species Possess Genes of the Type III and VI Secretion Systems, Which Can Affect the Development of Symbiosis. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-09-02 Vera I Safronova,Polina V Guro,Anna L Sazanova,Irina G Kuznetsova,Andrey A Belimov,Valentin V Yakubov,Elizaveta R Chirak,Alexey М Afonin,Yuri V Gogolev,Evgeny E Andronov,Igor A Tikhonovich
A collection of rhizobial strains isolated from root nodules of the narrowly endemic legume species Oxytropis erecta, O. anadyrensis, O. kamtschatica, and O. pumilio originating from the Kamchatka Peninsula (Russian Federation) was obtained. Analysis of the 16S ribosomal RNA gene sequence showed a significant diversity of isolates belonging to families Rhizobiaceae (genus Rhizobium), Phyllobacteriaceae

BcSas2-Mediated Histone H4K16 Acetylation Is Critical for Virulence and Oxidative Stress Response of Botrytis cinerea. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-09-02 Guangyuan Wang,Limin Song,Tingting Bai,Wenxing Liang
Histone acetyltransferase plays a critical role in transcriptional regulation by increasing accessibility of target genes to transcriptional activators. Botrytis cinerea is an important necrotrophic fungal pathogen with worldwide distribution and a very wide host range, but little is known of how the fungus regulates the transition from saprophytic growth to infectious growth. Here, the function of

Genome Resources for the Endophytic Fungus Paraphaeosphaeria sporulosa. Mol. Plant Microbe Interact. (IF 3.696) Pub Date : 2020-07-13 Riccardo Baroncelli,Daniele Da Lio,Giovanni Vannacci,Sabrina Sarrocco
Paraphaeosphaeria genus includes plant pathogens or biocontrol agents as well as bioremediators and endophytic fungi. Paraphaeosphaeria sporulosa 10515 was isolated in 2013 as an endophyte of Festuca spp. collected on Mount Etna at 1,832 meters above sea level. Here, we present the first-draft whole-genome sequence of a P. sporulosa endophytic isolate. This data will be useful for future research on
