“…First reported in the early 1900s (Brzezinski, 1902), the bacterial canker has caused large crop losses worldwide (Kennelly et al, 2007). The presence of causal agents of bacterial canker has been reported in several stone fruits growing countries worldwide (Bultreys & Kaluzna, 2010;Gilbert et al, 2009;Hassan et al, 2014;Otto et al, 2017;Renick et al, 2008;Vasinauskiene et al, 2008).…”

Bacterial canker of stone fruits caused by Pseudomonas syringae pv. syringae (Pss) and Pseudomonas syringae pv. morsprunorum (Psm race‐1/Psm race‐2) may lead to significant yield and crop losses in apricot (Prunus armeniaca L.) cultivation areas in Türkiye. Strains pathogenic to apricot were isolated from trees with symptoms (mainly necrotized buds and dieback) of bacterial canker in orchards in Aras Basin. Pathogens were characterized using pathogenicity tests, phenotypic assays, end‐point PCR and multilocus sequence analysis (MLSA). Fifteen Pseudomonas syringae strains were isolated from 205 plant samples collected from apricot orchards showing symptoms of bacterial canker. As a consequence of the diagnostic tests, all isolates were identified as P. syringae pv. syringae. In this study, Pss, Psm R1 and Psm R2 strains in stone fruits were separated into different phylogroups (Pg‐2, Pg‐3, sPg‐1b) based on MLSA. Turkish strains obtained from stone fruits, particularly apricot, showed genetic heterogeneity, and clustered in different sub‐phylogroups (sPg‐2b, sPg‐2c, sPg‐2d). All these strains except strain K258 are also clustered in the same sub‐phylogroups (sPg‐2b and sPg‐2d) with other strains from different countries especially Iran, Lebanon, etc. Strain K258 isolated from apricot was clustered in sPg‐2c with Pss strain 642 (USA). The risk of bacterial canker disease in apricot growing areas is considered using GIS in this study. It was determined that a significant part of the Iğdır Plain, the biggest agricultural area in the Aras Basin, is at very high risk.

“…Previous studies documented successful MLSA to distinguish the closely related B. pumilus group species in the marine environment using seven housekeeping genes ( gyrB , rpoB , pyrA , pyrE , aroE , mutL , and trpB ) ( Liu et al, 2013 ). Also, the MLSA has widely used for investigation of the taxonomic relationship and phylogenetic analysis of plant disease ( Abidin et al, 2020 ; Ansari et al, 2019 ; Ntambo et al, 2019 ; Osdaghi et al, 2018 ; Otto et al, 2018 ; Oueslati et al, 2019 ; Suárez-Moreno et al, 2019 ; Waleron et al, 2019 ; Yahiaoui et al, 2017 ; Zarei et al, 2019 ; Zhang et al, 2018 ).…”

Current Classification of the Bacillus pumilus Group Species, the Rubber-Pathogenic Bacteria Causing Trunk Bulges Disease in Malaysia as Assessed by MLSA and Multi rep-PCR Approaches

Bacillus pumilus is the causal agent of trunk bulges disease affecting rubber and rubberwood quality and yield production. In this study, B. pumilus and other closely related species were included in B. pumilus group, as they shared over 99.5% similarity from 16S rRNA analysis. Multilocus sequence analysis (MLSA) of five housekeeping genes and repetitive elements-based polymerase chain reaction (rep-PCR) using REP, ERIC, and BOX primers conducted to analyze the diversity and systematic relationships of 20 isolates of B. pumilus group from four rubber tree plantations in Peninsular Malaysia (Serdang, Tanah Merah, Baling, and Rawang). Multi rep-PCR results revealed the genetic profiling among the B. pumilus group isolates, while MLSA results showed 98-100% similarity across the 20 isolates of B. pumilus group species. These 20 isolates, formerly established as B. pumilus , were found not to be grouped with B. pumilus . However, being distributed within distinctive groups of the B. pumilus group comprising of two clusters, A and B. Cluster A contained of 17 isolates close to B. altitudinis , whereas Cluster B consisted of three isolates attributed to B. safensis . This is the first MLSA and rep-PCR study on B. pumilus group, which provides an in-depth understanding of the diversity of these rubber-pathogenic isolates in Malaysia.
