{"doi":"10.3389/fpls.2023.1224293","title":"Editorial: Genome-wide analyses of Pectobacterium and Dickeya species, volume II","abstract":"2021). All SRP species are characterized as necrotrophic pathogens capable of rapidly degrading plant tissue components upon which they feed (Toth and Birch, 2005).The estimated global costs associated with SRP bacteria in agriculture are high and continuously rising (van der Wolf et al., 2021a). As SRP are globally distributed and known to infect a wide range of monocot and dicot plants across diverse climatic conditions, the estimated cost of their presence and activities in vegetable, fruit, and ornamental plant production can reach up to 100 million USD annually (Dupuis et al., 2021;Arif et al., 2022).The success of SRP as pathogens relies on their ability to produce a diverse array of effectors, which play a crucial role in the colonization and establishment of infection in plants (Van Gijsegem et al., 2021). These effectors include plant cell walldegrading enzymes (PCWDEs), lipopolysaccharides (LPS), extracellular polymeric substances (EPS), indigoidine, siderophores, type I-IV secretion systems, enterobacterial common antigen (ECA), necrosis-inducing protein (Nip), citrate uptake, ferredoxin-like protein (FerE) motility and adhesion to plant tissues (Reverchon et al., 2016;Arizala and Arif, 2019).Although SRP bacteria have been extensively researched for over 50 years, studies targeting the global molecular background of virulence, host recognition, and niche adaptation of SRP bacteria to new hosts are limited. However, the recent advances in sequencing technologies combined with the rapidly decreasing sequencing costs have enabled targeting these critical research issues on a new scale.In this special issue, four articles were published. Robic and co-authors, in their article \"Dissimilar gene repertoires of Dickeya solani involved in the colonization of lesions and roots of Solanum tuberosum\" used transposon-sequencing (Tn-seq) to assess genes exclusively expressed in Dickeya solani during colonization and infection of potato roots, stems and tubers. They found D. solani genes essential for the competitive colonization of potato tuber tissue, 207 genes crucial for disease progression in infected stems, and 83 genes necessary for the colonization of potato roots by the bacterium. In addition, several D. solani root-colonization-essential genes were encoding proteins involved in the utilization of organic and mineral nutrients and the synthesis of metabolites helping the bacteria to invade plant tissues from soil. The authors selected four genes: bcsA, ddpA, apeH, and pstA, and constructed their inframe deletion mutants. The obtained mutants were virulent in stem assays. Still, they were impaired in colonizing potato roots. Such results indicate that depending on the nutrient availability, D. solani may exploit two distinct life strategies: oligotrophic on roots when the nutrient availability is limited and copiotrophic in nutrient-rich environments of macerated stem and tuber tissues.In the following article, \"Isolation and genome analysis of Pectobacterium colocasium sp. nov. and Pectobacterium aroidearum, two new pathogens of taro\", Zhou et al. reported a new Pectobacterium species isolated from taro (Colocasia esculenta) and named it P. colocasium. Likewise, the authors showed for the first time that another Pectobacterium species, P. aroidearum, can infect taro and establish a successful infection in this plant under natural conditions. This is the first study describing new pathogens causing taro soft rot in China. Furthermore, Zhou et al. analyzed the interaction of P. colocasium LJ1 and P. aroidearum LJ2 in the development of disease symptoms in taro. They showed that even though both pathogens were present in the same plant, they neither expressed synergistic nor antagonistic interactions with each other. Comparative analyses of the genome sequences of LJ1 and LJ2 strains and known genomes of Pectobacterium species revealed the existence of unique pathogenicity-related features present in LJ1 and LJ2 strains, in","journal":"Frontiers in Plant Science","year":2023,"id":399558,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9146,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":694878,"name":"Mohammad Arif","orcid":"0000-0002-5887-2050","position":1,"is_corresponding":false},{"id":983604,"name":"Toni A.
