Title: | Genetic Diversity of Pseudomonas syringae pv. actinidiae: Seasonal and Spatial Population Dynamics | Authors: | Figueira, Daniela Garcia, Eva Ares, Aitana Tiago, Igor Clemente Veríssimo, António Costa, Joana |
Keywords: | Actinidia chinensis var. deliciosa; Pseudomonas syringae pv. actinidiae; population genetic structure; endophytic and epiphytic populations | Issue Date: | 20-Jun-2020 | Publisher: | MDPI | Serial title, monograph or event: | Microorganisms | Volume: | 8 | Issue: | 6 | Abstract: | Pseudomonassyringae pv. actinidiae (Psa) is a gram-negative bacterium responsible for the bacterial canker in Actinidia chinensis var. deliciosa and A. chinensis var. chinensis, a quarantine organism threatening the kiwifruit industry sustainability. The present study aimed to determine the genetic structure of the endophytic and epiphytic populations of Psa isolated from four different Portuguese orchards with distinct abiotic conditions in two consecutive seasons. The results identified several coexisting and highly heterogeneous Psa populations. Moreover, evident changes in population structure occurred between the epiphytic and endophytic populations, and between seasons with a notable decrease in Psa diversity in autumn. This work provided solid evidence that the initial clonal expansion of Psa in Europe was followed by a wide genomic diversification. This perspective is important for the understanding of kiwifruit bacterial canker disease occurrence and Psa evolution, namely when adopting strategies for management of epidemics. | URI: | https://hdl.handle.net/10316/106453 | ISSN: | 2076-2607 | DOI: | 10.3390/microorganisms8060931 | Rights: | openAccess |
