“…The main focus of these genome sequencing projects has been on phytopathogenic isolates, including strains from pineapple, rice, Eucalyptus , cotton, maize and onion (Adam et al ., ; Choi et al ., ; De Maayer et al ., ; Medrano and Bell, ; Weller‐Stuart et al ., ). However, a variety of endophytic isolates (Midha et al ., ; Sheibani‐Tezerji et al ., ), plant growth‐promoting strains, isolates with potential biotechnological and biological control applications (Gasser et al ., ; Gkorezis et al ., ; Hara et al ., ; Kim et al ., ; Megías et al ., ; Shi et al ., ; Smith et al ., ; Wu et al ., ) and a clinical isolate (De Maayer et al ., ) have also been sequenced.…”

“…Although much P. ananatis research has focused on pathogenicity on various plant hosts, this bacterium also provides us with an array of beneficial characteristics that we have only just begun to investigate. For example, several strains are known to aid the growth of their host plants, such as poplar (Gkorezis et al ., ), onions (Kim et al ., ), papaya (Thomas et al ., ) rice (Megías et al ., 2016; Sanchez‐Matamoros et al ., ) and red pepper, and can increase crop yield up to three times (Kim et al ., ). Several P. ananatis strains are capable of phosphate solubilization (Kim et al ., ; Megías et al ., 2016), whereby organic and inorganic forms of phosphorus are solubilized and converted into a bioavailable form for plant root growth, seed formation and major metabolic processes, such as photosynthesis and respiration (Sharma et al ., ).…”

“…The taxonomy of the genus has been described based mainly on morphological and ultrastructural information. A few studies employed rDNA sequencing for species identification in limited collections of Tetraselmis strains (Lee and Hur, 2009;Arora et al, 2013;Gonz alez et al, 2015), however, systematic taxonomic studies of the genus combining morphological and molecular approaches are lacking.…”

Qualified presumption of safety (QPS) was developed to provide a generic safety evaluation for biological agents to support EFSA's Scientific Panels. The taxonomic identity, body of knowledge, safety concerns and antimicrobial resistance are assessed. Safety concerns identified for a taxonomic unit (TU) are where possible to be confirmed at strain or product level, reflected by ‘qualifications’. No new information was found that would change the previously recommended QPS TUs and their qualifications. The list of microorganisms notified to EFSA was updated with 54 biological agents, received between April and September 2019; 23 already had QPS status, 14 were excluded from the QPS exercise (7 filamentous fungi, 6 Escherichia coli, Sphingomonas paucimobilis which was already evaluated). Seventeen, corresponding to 16 TUs, were evaluated for possible QPS status, fourteen of these for the first time, and Protaminobacter rubrum, evaluated previously, was excluded because it is not a valid species. Eight TUs are recommended for QPS status. Lactobacillus parafarraginis and Zygosaccharomyces rouxii are recommended to be included in the QPS list. Parageobacillus thermoglucosidasius and Paenibacillus illinoisensis can be recommended for the QPS list with the qualification ‘for production purposes only’ and absence of toxigenic potential. Bacillus velezensis can be recommended for the QPS list with the qualifications; the absence of toxigenic potential and the absence of aminoglycoside production, including the genes encoding this. Cupriavidus necator, Aurantiochytrium limacinum and Tetraselmis chuii can be recommended for the QPS list with the qualification; for production purposes only. Pantoea ananatis is not recommended for the QPS list due to lack of body of knowledge in relation to its pathogenicity potential for plants. Corynebacterium stationis, Hamamotoa singularis, Rhodococcus aetherivorans and Rhodococcus ruber cannot be recommended for the QPS list due to lack of body of knowledge. Kodamaea ohmeri cannot be recommended for the QPS list due to safety concerns.

“…Therefore, following its entry, its transfer to a suitable host and its establishment may be assisted by its permanence in the environment as an epiphyte/endophyte on several plants, in plant debris, in surface water, in the gut of several insects. The presence of P. ananatis in the EU territory as a saprotroph, commensal, opportunist or beneficial organism is certain (De Baere et al, 2004 ; Gkorezis et al, 2016 ; Sheibani‐Tezerji et al, 2015 ; Megías et al, 2016 , 2017 ). Nonetheless, there is no specific study on its presence and distribution: this is a key uncertainty.…”

The EFSA Plant Health Panel performed a pest categorisation of Pantoea ananatis , a Gram‐negative bacterium belonging to the Erwiniaceae family. P. ananatis is a well‐defined taxonomic unit; nonetheless, its pathogenic nature is not well defined and non‐pathogenic populations are known to occupy several, very different environmental niches as saprophytes, or as plant growth promoting bacteria or biocontrol agents. It is also described as a clinical pathogen causing bacteraemia and sepsis or as a member of the gut microbiota of several insects. P. ananatis is the causal agent of different diseases affecting numerous crops: in particular, centre rot of onion, bacterial leaf blight and grain discoloration of rice, leaf spot disease of maize and eucalyptus blight/dieback. A few insect species have been described as vectors of P. ananatis , among them, Frankliniella fusca and Diabrotica virgifera virgifera . This bacterium is present in several countries in Europe, Africa, Asia, North and South America, and Oceania from tropical and subtropical regions to temperate areas worldwide. P. ananatis has been reported from the EU territory, both as pathogen on rice and maize and as an environmental, non‐pathogenic bacterium in rice marshes and poplar rhizosoil. It is not included in EU Commission Implementing Regulation 2019/2072. The pathogen can be detected on its host plants using direct isolation, or PCR‐based methods. The main pathway for the entry of the pathogen into the EU territory is host plants for planting, including seeds. In the EU, there is a large availability of host plants, with onion, maize, rice and strawberry being the most important ones. Therefore, disease outbreaks are possible almost at any latitude, except in the most northern regions. P. ananatis is not expected to have frequent or consistent impact on crop production and is not expected to have any environmental impact. Phytosanitary measures are available to mitigate the further introduction and spread of the pathogen into the EU on some hosts. The pest does not satisfy the criteria, which are within the remit for EFSA to evaluate whether the pest meets the definition of a Union quarantine pest. P. ananatis is probably widely distributed in different ecosystems in the EU. It may impact some specific hosts such as onions while on other hosts such as rice it has been reported as a seed microbiota without causing any impact and can even be beneficial to plant growth. Hence, the pathogenic nature of P. ananatis is not fully established.
